Description

 Processed product and method for naked-flavored walnut and easy-to-skin naked multi-flavored nitrogen-filled nut

 [1] The present invention relates to a edible nut. In particular, it relates to a class of nut convenient foods and processing methods.

 Background technique

 [2] Walnut is a traditional food of human beings. Walnuts and walnut kernels are produced in dozens of countries and regions all over the world. The processing methods and reprocessing of their production are also changing with each passing day.

 [3] The walnut kernels in the well-known walnut husks have a layer of kernels, also known as lentil, seed coats, seed coats (hereinafter referred to as kernels), which are bitter and have an effect on the palatability of walnut kernels. Fresh walnut fruit can be peeled and peeled off by hand. The fresh walnuts peeled off and peeled are crispy, sweet and fragrant. The taste is very beautiful, but it is not easy to preserve, and the processing efficiency is extremely low. There are fewer people, and they can only be enjoyed during the picking period of walnuts.

 [4] The walnut nuts suitable for long-term preservation and the walnut kernels after shelling are deeper due to the folds on the surface, and the kernels are firmly attached to the kernels and are difficult to peel off, so that most of the consumption In accepting the delicious colleagues of walnuts, they have to accept the bitterness of walnut kernels.

 [5] The color of Renpi is currently an important criterion for the pricing of walnut kernels in international trade. It can be seen that the influence of kernels on the quality of walnut kernels and the difficulty of separation are a consensus.

 [6] In many methods of deep processing of walnut kernels, it is necessary to remove the walnut kernels. For example, in the cooking, the skin is peeled off by hot water soaking, and some deep processing is used to remove the walnut kernels by acid and alkali solution corrosion. The purpose of the skin is to remove the pigment and bitterness of the walnut kernels and affect the color and taste of the food. However, these known methods are not very inefficient in eliminating this effect, that is, to sacrifice the nutritional value of the walnut meat. Or at the expense of security.

 [7] Nuts such as walnuts, hazelnuts, and pine nuts are nutritious and delicious. The fruit is removed from the shell by the use of the nutrients. Although the shelling can be carried out at the factory, the repackaging of the nuts brings waste, and the corresponding food safety and trust issues also affect consumer demand.

[8] Open walnuts, open hazelnuts, etc., which were artificially inspired by pistachios, belong to the manufacture of obvious cracks on the shell. The method, although bringing some convenience to the use of nuts, can not completely rule out the contamination of nuts in the circulation of goods, food safety and the corresponding trust issues can not be ignored.

 Nuts and nuts are nutritious and delicious foods. Not only humans know, but other organisms also know that oxidation and insects are the main causes of deterioration in the storage or circulation of edible nuts. The prevention and control of edible nuts in storage and circulation is also an important issue in the safety of edible nut foods.

Disclosure of invention

technical problem

 People really need an economical and safe way to remove or reduce the kernels on the walnut kernels, so that the walnut kernels can be as white and white as the almonds and peanut kernels, so that more people can enjoy the walnuts. It is the main purpose and the pursuit effect of the present invention to reduce the bitterness brought by Renpi. People also need nuts such as walnuts, hazelnuts, pine nuts, etc., which have a hard outer shell and are not easy to remove the internal tissues. They can be like peanuts, which can be used to keep the nut shells in a natural and complete state, and to take nuts with convenience. It can prevent oxidation and insects, and solve the corresponding food safety and trust problems.

Technical solution

 SUMMARY OF THE INVENTION It is an object of the present invention to provide a walnut nut product in which the walnut kernel and the kernel are in a state of discontinuous contact and easy separation; and the core peach shell is still in a complete or substantially intact state and a method of processing the walnut nut product. Peer provides one or a type of nut product and processing method that can keep the nut shell in a natural and complete state and facilitate the use of nuts.

 Walnut kernel and kernel are in a state of non-continuous contact and easy separation; it refers to the state in which the walnut kernel and the kernel are partially separated, partially separated, and partially contacted but easily separated, in order to distinguish it from the continuous continuity of walnut kernel and kernel. The contact is not easily separated. Walnut kernel and kernel are partially separated, partially separated, and partially contacted but easily separated. The state in which the walnut shell is still intact or substantially intact, and the space of the shell is limited.

 The ingenious feature of the present invention is that the inner wall of the walnut itself and the folds of the walnut kernel are closely adjacent to each other, so that the shell itself becomes an effective tool for peeling the kernel.

The method for realizing the walnut processed product of the invention is designed according to the principle that the combination of the outer layer of the outer layer and the inner layer of the walnut layer, that is, the walnut kernel and the outer shell is stronger than the natural connection between the kernel and the meat. , In this way, during the drying process of the walnut kernel, the kernel meat is naturally separated from the kernel skin or the bonding strength is significantly reduced, so that the skin is peeled off from the kernel meat in the peeling shell.

 [15] The method of combining the walnut kernel with the outer shell is to fill the natural gap with a binder solution, and the walnut concentrates the binder during the inhalation of the binder solution, and Produces water swelling and presses the walnut kernel skin from the inside to the outside on the inner wall of the outer shell. This is dried from the outside. The first shrinkage is the walnut shell, then the bonding layer between the shell and the walnut kernel is dry. The bond is solidified, and after curing, the skin is further dried to make the wrinkles of the kernels stretch, pulling the kernels to uniformly separate the kernels from the deep folds, and finally allowing the kernels to dry and shrink in the drying and further detached from the cured shell. Renpi. Thereby achieving its purpose of artificially using the walnut shell to peel off the walnut kernel from the walnut kernel.

 [16] The core method of processing walnuts is to artificially fill the natural gap between the outer shell of the walnut and the walnut kernel to make the kernel and outer shell, including interspersed with walnuts. The center of the center of the center of the wood (also known as the diaphragm), forming a bond that is not easy to separate; processed walnuts, peeled off the shell with walnuts, the kernels on the walnuts will be accompanied by the walnut shell Stripped.

 [17] The present invention provides one or a type of nut product and a processing method which can maintain the nut shell in a natural and complete state and facilitate the use of nuts. This nut product is obtained by processing dark marks on the nut shell. The outer shell of such a nut product has a processed dark mark that is easily cracked along the processed portion while remaining in a naturally occurring state or substantially remaining in a natural intact state. This processed nut, after taking its nuts, squeezes its outer shell by hand to crack the nut shell along the dark spots without the use of tools. The processed nuts include the above-mentioned naked walnuts and walnuts, hazelnuts, apricot kernels, pine nuts and other nuts with a hard outer shell which are difficult to remove the internal tissues by hand, or at least one of them, the product name corresponding to the easy open naked Walnuts, easy-opening walnuts, easy-opening hazelnuts, easy to open pine nuts, etc.

 [18] The method of realizing such a processed product is to artificially freeze the shell of the water-containing nut to artificially freeze the crystal of the moisture at the frozen portion to damage the tissue structure to form a hidden scar. Because of this hidden scar, that is, the dark mark reaches a certain degree, the nut shell is easily cracked along the processing part, and the unprocessed part can maintain the corresponding damage resistance strength. The degree of damage and distribution of the damaged tissue structure of the processed dark mark on the nut shell is limited to the fact that the nut shell is easily cracked without cracking.

[19] In the present invention, in order to achieve the object of the invention described above, the processed nut product has a function of preventing oxidation and preventing insects during storage without increasing the input and the process. Beneficial effect

 [20] The present invention changes people's traditional understanding, this kind of understanding that walnut kernels are a component of walnut kernels, and the color of kernels is currently one of the criteria for grading pricing of walnuts in international trade. A common reflection is that this kind of understanding also believes that it is impossible to peel off the skin without opening the outer shell of the walnut.

 [21] The present invention provides a novel way of presenting the naked kernel of the walnut, that is, it exists in its original intact shell and the intact two-layer original packaging of the kernel, avoiding the processing of the walnut kernel and even the walnut kernel. Pollution during transportation and circulation provides a solution to food safety and the problems of trust.

 [22] The present invention also provides a new method of protecting a new variety of walnuts. Walnut kernels are different from peanuts, beans and other dicotyledonous kernels. Walnuts are used as seeds to germinate. The hazelnut skin is an effective tissue for transporting cotyledons to germs. The separation between kernels and kernels is not easy to separate and become walnuts. As an important influencing factor of plant seed germination survival rate, the processing method of naked kernel walnut is mainly to improve the quality of food service, objectively destroying the close combination between the kernel and the meat, effectively reducing the walnut as a plant. Germination and survival rate of breeding seeds.

 [23] Adults who are new varieties of walnuts often face a dilemma. They want to increase the sales of walnuts to recover the cost of breeding, and they do not want to sell the edible walnut products for seed use and reduce the breeding benefits. The impact of protective demand on the supply of consumer demand has plagued the breeding of new varieties of walnut. The processing method of naked walnuts has significantly reduced the economics of edible walnut products as plant seeds, thus providing a technical protection option for high quality walnut breeders to protect their legitimate interests. The survival rate of walnut fruit as a breeding seed can be effectively reduced, and the legitimate benefits of protecting high-yield and high-quality walnut varieties for adult breeding will not be impaired due to the supply impact of protective demand on consumer demand.

[24] The inventor has an important finding that the consumers of fresh walnuts have no adverse reactions after the nuclear peaches have been reported in some books. The source of the adverse reactions may come from the skins that are not easily removed. Whether the walnut kernel skin has the same medicinal effect as peanut kernel skin, or the adverse reaction of eating more walnuts and whether the medicinal value of walnut is mainly derived from kernel skin, is not a problem to be solved by the present invention, but the invention has the advantages of eliminating walnuts. Adverse reactions and the possibility of collecting walnut kernels for pharmaceutical use.

[25] Walnuts and naked walnuts provide people with more palatable food and food deep processing materials.

[26] It is possible to keep the nut shell in a natural and complete state and to use nut products and processing methods that are convenient for nuts. It provides a solution to the convenience of nuts and the trust of food safety. The present invention provides an option to increase the market competitive advantage of nut processed products. Try to solve the corresponding food safety and trust issues.

 DRAWINGS

 [27]

 BEST MODE FOR CARRYING OUT THE INVENTION

[28] First step:

 [29] Picking out the peeled green skin, the whole shell is intact, and the walnut nuts which have gaps between the shell and the nuts are treated as the processing object by preliminary air drying; the water-soluble glue such as starch glue is used as the main solute, and water is used as the solvent. The binder solution; the salt, sugar and the like may be selectively added to the solution to make the processed product have a multi-flavor characteristic.

 [30] Step 2:

 [31] The object to be processed is placed in a vacuum-capable container, and after the vacuum is drawn to form a vacuum negative pressure, the pre-formed binder solution is added and the processed walnut is immersed, and then the vacuum is released to normal. Pneumatic pressure, and let the walnut soak in the pre-mixed binder solution until the walnut kernel absorbs water and expands so that the contact between the kernel and the walnut shell is as large as possible; in the process of soaking, the seed kernel is not well developed and the seed kernel is not developed. Kernel walnuts are removed by flotation.

 [32] Step 3:

 [33] The soaked walnuts are clamped with a jig made of insulating material, and only the portion of the outer surface of the walnut shell on which the distraction wood is located is the gap. The jig and the clamped walnuts are immersed in liquid nitrogen for half a second to several seconds, and can be quickly immersed in the soaking liquid and liquid nitrogen for several times. The number of times of contact between the parts of the walnut shell to be processed and the liquid nitrogen is contacted. Due to the size and thickness of the walnut, it was adjusted by experiment.

 [34] Step 4:

 [35] The walnut fruit after soaking is air-dried, the moisture on the shell is quickly removed, and the binder solution is concentrated in the dry state until solidified.

[36] Step 5:

[37] After the binder is cured, the walnut fruit is further dried by a known method such as vacuum drying to a degree suitable for long-term storage, and the drying strength is controlled so that the nut is removed from the shell by the binder during the shrinking process. Renpi ; Release the vacuum negative pressure to the normal pressure, fill the nitrogen vapor evaporated by the liquid nitrogen absorption in the third step, and make it easy to open the multi-flavored nitrogen-filled dry bare walnut.

 [38] The above five-step process briefly describes a nut processing method using walnut as an example, and the inventors have taken this as a preferred embodiment, and organically combines several processing methods of the present invention based on the above five-step process and can Maximize the effect and minimize consumption.

 [39] The binder solution in the first step process is both a carrier for the binder and a carrier for the flavoring agent in the organic combination of the five-step process, and the same is the second step of the walnut kernel soaking flotation and the third step. In the step process, the soaking liquid for freezing and scoring is realized on the shell, and a liquid is continuously immersed to realize four functions.

 [40] The liquid nitrogen in the third step is the cryogen that realizes the freezing scoring. It is converted into gaseous hydrazine and can also be used as a refrigerant for the production of finished fresh walnuts, which is converted into a gas chiller and can be eliminated in the fifth. In the step process, the gas as an anti-oxidation and anti-worm is filled in the inner space of the nut shell which is used to release the vacuum negative pressure, so that the liquid nitrogen is used in three ways.

 [41] The vacuum equipment in the second step process is used to efficiently fill the binder solution in the nut shell, and also as a device for drying nuts and nut nitrogen, so that the equipment utilization rate is improved by one machine.

 [92] 3. Implementation of easy-to-open features

[93] Example 9 easy to open walnut

 [94] Soak the walnuts that have just been removed from the green skin and wash away the stains on the surface of the shell. During the soaking process, the walnuts with poor development of the kernels and the undeveloped kernels are removed by flotation; in the freshly soaked liquid When the fish is removed, it is clamped with a clamp made of insulating material, and only the gap of 1-3 mm on the plane of the distraction wood is exposed. The walnuts and clamps are immersed in liquid nitrogen for half a second to several seconds, and can be repeatedly immersed in the soaking solution and liquid nitrogen for several times. Then remove the fixture and go into the drying operation. After drying, the walnut hand can squeeze the walnut shell in the direction of the distraction wood to split into two halves along the distraction wood plane. The inter-turn and contact times of the walnut shell processing parts in contact with liquid nitrogen were adjusted experimentally due to the size and shell thickness of the walnut.

 [95] Example ten easy to open the dice

 [96] The scorpion that has just been removed from the fruit pod is soaked, and the scorpion scorpion which is not well developed and the seed kernel is not developed is removed by flotation during the soaking process, and the heat insulating material is used when it is just removed from the soaking liquid. The resulting clamp is clamped and only reveals a gap of 1-3 mm through the plane of the husk of the scorpion shell and the largest circumference of the fruit tip. Dip the tweezers and clamps into liquid nitrogen for half a second to several seconds and quickly immerse them in the soaking solution and liquid nitrogen for several times. Then remove the fixture and go into the drying operation. After drying, the scorpion can be split into two halves by hand. The number of times of contact between the processing part of the scorpion shell and the liquid nitrogen and the number of contacts were adjusted according to the size and thickness of the scorpion.

 [97] The above described production process is described in the processing of two embodiments:

[98] The selected and used nuts are soaked. During the soaking process, the nuts with poor development of the kernels and the undeveloped kernels are removed by flotation, clamped with a clamp made of insulating material, and the nut shell is in the fixture. Only the part to be processed is exposed, the nut and the clamp are immersed in liquid nitrogen for half a second to several seconds, and can be repeatedly immersed in the soaking liquid and liquid nitrogen for several times, and the moisture of the frozen part is crystallized and expanded by local freezing. The tissue structure forms hidden scars, so that the hidden scars, that is, the dark marks, can be easily broken. The degree and extent of damage to the damaged tissue structure of the processed dark marks on the nut shell is limited to the fact that the nut shell is susceptible to cracking without cracking. The jig is then removed and dried to make easy-open nuts. [99] Due to different nut varieties, different production areas, different fruit size and shell thickness, etc.; it is impossible to enumerate the number of times and contact times in contact with liquid nitrogen, but these are not tested in production. It is difficult for the technician to adjust according to the results, and does not affect the substantial disclosure of the solution of the present invention.

 [100] 4. Implementation of anti-oxidation and anti-worm characteristics

 [101] Example 11 nitrogen-filled nuts

 [102] The shelled edible nuts, such as walnuts, almonds, hazelnuts, etc., to be stored or circulated, or the products processed in the second, fourth, sixth, eighth, ninth and tenth embodiments of the present invention are placed in a container capable of achieving a vacuum environment. Vacuuming inside, after the extracted air reaches more than 90%, it is filled with nitrogen to release the vacuum negative pressure to normal pressure; the oxygen content of the gas in contact with the edible tissue structure of the nut is significantly lower than the oxygen content in the atmosphere, and the processing nut is improved. Anti-oxidation and insect-proof ability.

 [103] The nitrogen gas to be charged may be the nitrogen gas volatilized after the refrigeration machine can be removed after the liquid nitrogen is absorbed by the liquid.

 Industrial applicability

 [104] Since the walnut fruit is naturally in the outer edge of the shell, that is, the walnut umbilical part corresponding to the stalk of the walnut fruit has a liquid-accessible passage. In this part, the binder solution can be introduced into the gap between the shell and the skin, which can be formed by the natural drying of the walnut fruit, so that it is not necessary to destroy the natural integrity of the shell, that is, the needle is injected by needle injection or needle-free injection. The umbilicus channel presses the aqueous solution of the binder into the nut shell, and then flows the binder solution evenly on the inner wall of the walnut shell by centrifugal rotation, and increases the bonding surface to achieve maximum peeling. The role of walnut kernels.

 [105] The core method of processing walnuts is to artificially fill the natural gap between the outer shell of the walnut and the walnut kernel to make the kernel and outer shell (including interspersed with walnuts). The distracting wood in the middle of the center forms a bond that is not easily separated; the processed naked walnut is peeled off from the outer shell after the walnut is removed, and the kernel on the walnut will be peeled off along with the walnut shell.

 [106] The implementation of the characteristics of the naked man, the purpose is to provide a walnut kernel and kernel skin in a state of non-continuous contact and easy separation; while the walnut shell is still in a complete or substantially intact state of walnut fruit products, namely naked walnut .

[107] Walnut kernel and kernel are in a state of non-continuous contact and easy separation; it means that the walnut kernel and the kernel are partially separated, some are about to be separated, and some are in contact but easily separated, to distinguish it from walnut kernel and kernel. The original continuous contact is not easily separated. Walnut kernel and kernel are partially separated, Part of the state that is about to be separated and partially contacted but easily separated means that the walnut shell is still intact or substantially intact, and the shape of the shell cavity is limited.

 [108] The popularity of vacuum technology has provided an improved way to improve the above-mentioned processing methods by injecting a binder solution from the umbilicus of the walnut into a vacuum environment and using atmospheric pressure to inhale the binder solution from any channel on the walnut shell. And filling the gap between the inner wall of the walnut shell and the walnut kernel, any passage on the walnut shell including the umbilicus of the walnut is not limited to the liquid-permeable passage naturally formed in the umbilicus of the walnut, and the three-step process is completed in one step.

 [109] Embodiment for realizing multi-flavor characteristics in a vacuum condition The manner of realizing the above solution is to put a processing object prepared in the first step of the first embodiment into a container capable of realizing a vacuum environment, and wait for a vacuum. After the air is extracted by more than 90%, a pre-binder solution containing a binder and other flavoring agents is added and the processed walnut is immersed, and then the vacuum is released to normal pressure, and the walnut is pre-bonded. In the solution, "soaked into the walnut kernel to absorb water and expand the contact between the kernel and the walnut shell as much as possible", this method of three-step process is one step to effectively overcome the defects of the injection method, so that one by one becomes Batch processing can ensure the filling rate of the binder solution is above 90%, eliminating the centrifugal processing, and changing the soaking liquid from the clear water to the binder solution, so that the consumption of the filling binder solution can be easily measured and the amount of reuse can be repeated. The crumbs have been taken out of the walnut shell after vacuuming, and the immersed walnut stalk has been suspended in the surface of the binder solution; since the binder solution is filled in the same manner as the immersion, That the addition of flavoring agents to the processed kernels walnut taste in the marinade soaking the seasoning step in the present work also be resolved.

 [110] The implementation of the easy-opening feature is that the nut shell of the soaked nut is locally frozen to cause the crystal of the frozen part to crystallize and damage the tissue structure to form an hidden scar, so that the hidden scar is a dark mark. To a certain extent, the nut shell can be easily cracked along the processing site. The jig is then removed and dried to make easy-open nuts.

 [111] There are many ways to achieve this type of local freezing. The development of the steel industry has led to a large demand for liquid oxygen, making liquid nitrogen a by-product of liquid oxygen providing economics for such local freezing. The utility of the invention is based on this economy.

[112] The process combination of the invention can be used for the processing of walnuts to produce twelve new products: 1 dry naked walnut, 2 fresh naked walnut, 3 easy to open naked walnut, 4 easy to open naked walnut 5 more dry bare walnuts, 6 more fresh bare walnuts, 7 flavors easy to open dry naked walnuts, 8 flavors easy to open fresh naked walnuts; 1 frozen Multi-flavored fresh walnuts, 2 frozen raw fresh walnuts, 3 dried walnuts, 4 plain dried walnuts.

 [113] The first eight are shelled walnuts, the latter four are walnut kernels, and shelled walnuts and walnut kernels have been the main product forms of walnut international trade.

 [114] The process combination of the present invention can also be used for the processing of other nuts, such as walnuts, which have a hard outer shell and are easy to remove the internal tissues, and are made of a nut shell which is easy to open, odorous, bare, and nitrogen-filled. In a natural and complete state, the nuts are easy to use, just like the walnuts with a hard shell. The skin of other nuts that are not easy to remove the internal tissues. The effect of peeling on the food and the difficulty of peeling are not prominent enough compared to the walnut.
