Definitions
- the invention relates to a method for preparing a novel vegetable gum-linseed gum. Background technique
- Flaxseed gum is a pure natural, pollution-free, multifunctional, nutrient-rich vegetable gum. It is a green food additive certified by the National Green Food Development Center. It is mainly used as a thickener and humectant in food, pharmaceutical, and cosmetics fields. , Stabilizers, emulsifiers and adhesives.
- An object of the present invention is to provide a method for extracting linseed gum from linseed.
- the method of the invention has simple process, stable rubber extraction yield above 6%, no environmental pollution, and greatly reduced production cost.
- the method for extracting linseed gum from linseed according to the present invention includes the following steps:
- the steps of extraction, liquid-solid phase separation and concentration are all performed in an extraction tank with a stirring blade and a filter filter plate.
- a filter plate is installed in the lower part of the extraction tank, and a rotatable filter plate is installed.
- Scraper is installed in Chinese Patent Application No. 00247105.1, which is incorporated herein by reference.
- step a of the present invention the water extraction is performed 2 to 6 times.
- the weight ratio of flax seed to water at the first extraction is 1: 3-15, and the weight ratio of flax seed to demineralized water at each subsequent extraction is 1: 2-8.
- Demineralized water is preferably used in the extraction.
- the temperature is maintained at 35-100 ° C, and the extraction time is 10-100 minutes.
- constant stirring is required, but no other chemical reagents are added.
- step b of the present invention the liquid-solid phase separation is performed by pressurizing or pumping filtration in the extraction tank, and at the same time Rotate the stirring blade so that it continuously sweeps the filter plate to keep the filter surface clean and unobstructed. And the filtrate can be heated at the same time to reduce the temperature of the filtrate to facilitate filtration.
- One of the difficulties in extracting linseed gum is the separation of the leaching solution from the linseed after the extraction. The present invention solves this problem well through the above method.
- the concentration is performed under normal pressure or reduced pressure (500-700 mmHg), with stirring by a scraper, and the glue solution is concentrated to 1/2 to 1/20 of the original volume.
- the concentration time can be greatly reduced by reducing pressure and scraping the agitation.
- the concentrated gum solution obtained by the above method can be directly dried, and the properties of the flaxseed gum can be kept unchanged.
- the method further comprises the step of adding an ethanol solution with a weight ratio of 1: 0.6-1.5 to the concentrated gum solution at room temperature under stirring, to precipitate the gum solution, and drying after the solid-liquid separation.
- the ethanol solution is preferably a 95% ethanol solution.
- the drying may be carried out by hot air purging drying, wherein the temperature of the hot air is 70-140 ° F. Drying can also be carried out by coating the concentrated gum solution on a carrier and drying it by microwave heating.
- the yield of the method of the invention is as high as 6-15%, and the process is simple, does not cause environmental pollution, and the production cost is greatly reduced. Flaxseed after extraction can still be used for oil extraction, and the oil yield is not significantly different from that before extraction.
- the performance of the obtained flaxseed gum product is better than similar gums, such as carrageenan and konjac gum, etc., and it is an ideal substitute product. It can be widely used as thickener, humectant, stabilizer, emulsifier in food, pharmaceutical, cosmetics and other fields.
- Adhesives and adhesives have the advantages of high viscosity, high moisture retention, and good stability.
- step 2 Add the solid material separated in step 1 to 1:10 demineralized water at a temperature of 55 ° C, stir at normal pressure for 30 minutes, separate the seed solution, and repeat the extraction 3 times to obtain glue solution 8, C , D.
- step 2 Add the solids separated in step 1 to demineralized water with a weight ratio of 1: 5 and a temperature of 40 ° C, stir for 30 minutes under normal pressure, separate the seed liquid, and repeat the extraction three times to obtain glue solutions 8, C, and D. .
- the concentrated glue solution is coated on a polyester mesh, dried by microwave heating, and a flaxseed gum product is obtained after drying.
- step 2 Add the solids separated in step 1 to demineralized water with a weight ratio of 1:10 and a temperature of 70 ° C, stir for 20 minutes under normal pressure, separate the seed liquid, and repeat the extraction three times to obtain gums 8, C, and D.
