A kind of freshness preserving package method for fruit non-refrigeration transport
Technical field: the present invention relates to a kind of fruit freshness preserving packing method, particularly to starching the non-refrigerated transport fresh-preserving packing method of class fruit such as red bayberry, strawberry and loquat etc.
Background technology: at present, fresh-keeping and storage process technology hysteresis in the postpartum of China's fresh provisions or agricultural byproducts, the high speed that does not catch up with China rural economy crop increases progressively, and has had a strong impact on the increment of China's agricultural byproducts, vast farmers is got rich strive for a relatively comfortable life to be subjected to obstruction.As packaging industry, be that the important industry of protection and sales promotion is provided for product specially, and fresh-keeping, the storing and the sale that are packaged as agricultural byproducts have played key effect.Agricultural byproducts want fresh-keeping must good packing technique and packaging product.At the fresh-keeping package technology of important fresh-keeping and the means of hoard of food or agricultural byproducts, two aspects of external main research, first freshness preserving equipment is as cold storing and fresh-keeping car, cold storing and fresh-keeping storehouse, refrigeration strong box etc.; It two is packing such as fresh-keeping packaging softwood, composite fresh-keeping softwood, and as preservative film, fresh-keeping beverage paper composite tanks etc., particularly the paper composite tanks has been widely used in the fresh-keeping packaging of beverage series products.They have solved the fresh-keeping flexible packaging of liquid beverage, and lack research for having the preservation method of transportation with storage function.The producer of domestic fresh-keeping package technology research is a lot, the content of research mainly concentrates on the freshness preserving equipment, as air-conditioned cold store, ozone and ultraviolet sterilization freshness preserving equipment and refrigeration strong box etc., be exactly the flexible packaging Perserving materials in addition, these aspects are similar with content to the foreign study mode, this type of is fresh-keeping inconvenient with means of hoard use, cost is higher, simultaneously common packing chest, packing box is except general packaging function, not possessing has multifunctionality, as protection against the tide, radiation proof, heat insulation, fresh-keeping etc., it is fresh-keeping to be not suitable for non-refrigerated transport, particularly as red bayberry, slurry such as strawberry class fruit, because fruit does not have shell or harder crust, especially easily oxidized and microbiological attack and damaging is difficult to fresh-keepingly, generally is no more than 2-3 days and just produces rotten, spoiled, become rotten phenomenon.
Summary of the invention: the objective of the invention is to provides slurry class freshness preserving package method for fruit non-refrigeration transport such as a kind of suitable red bayberry, strawberry for overcoming the deficiencies in the prior art.
The objective of the invention is to reach by following scheme: a kind of freshness preserving package method for fruit non-refrigeration transport is characterized in that may further comprise the steps:
A, wash clean with thimerosal fruit and be cooled to below 10 ℃;
B, in the nutritional supplementation antistaling agent, soaked 3-5 minute;
C, will soak overnutrition and replenish fruit after the antistaling agent and take out and drain;
D, the fruit after will the draining crisper packing of packing into;
E, will pack later fruit with crisper and pack in the thermal insulation carton;
Wherein said nutritional supplementation antistaling agent comprises nontoxic macromolecule filming material and the biological film forming agent that is no less than total weight 2 ‰, is no more than the biological preservative of total weight 2 ‰ and is no less than the nutritional agents of total weight 2 ‰, and all the other are water; Described thermal insulation carton is covered with the plastics lamella by the surface or/and the corrugated board moulding of the ply of paper of aluminizing forms; Described crisper adopts the BOPS sheet material to press empty moulding, and handles through antifog anti-frosting.
After the processing of fruit through the nutritional supplementation antistaling agent; can form layer protecting film at fruit surface separates they and air; provide nutrient for fruit on the one hand; prevent germ further invasion and attack and oxidation on the other hand; in addition; the thermal insulation packing chest can make the temperature inside the box maintain a suitable temperature as far as possible longways; and has protection against the tide; the function of radiation proof and absorption ethene; so freshness date that can prolong fruit to a great extent; can make slurry class fruit such as red bayberry; strawberry and loquat etc. are fresh-keeping more than five days; and make it finally to realize that the non-refrigerated transport from the place of production to the market is fresh-keeping, reduced fresh-keeping traffic cost widely.
The invention will be further described below in conjunction with specific embodiment.
The specific embodiment:
Non-refrigerated transport fresh-preserving packing method will be to fruit through steps of processing: at first harvestings such as fruit such as red bayberry, strawberry are got off, and according to size, degree of ripeness, collide with and situation such as insect bite sorts arrangement, rotten, rotten the picking out of change, then wash clean and be cooled to below 10 ℃, put into antistaling agent immersion 3-5 minute with biological antiseptic liquid; The fruit drop that will soak again after the antistaling agent anhydrates, in the crisper of then fruit being packed into the packing, to pack later fruit with crisper at last packs in the thermal insulation carton, wherein the nutritional supplementation antistaling agent comprises nontoxic macromolecule filming material and the biological film forming agent that is no less than total weight 2 ‰, be generally between the 0.8%-2 ‰ of total weight, biological preservative can be potassium sorbate, in sodium sorbate or the gibberellin any or their mixture, the biological antiseptic agent content does not surpass 2 ‰ of total weight, in order to avoid the excessive relevant national standard that do not meet of biological preservative, nutritional agents is by sucrose, vitamin C, citric acid and calcium chloride are formed, content total weight 2 ‰-1% between, filmogen can be PVA (polyvinyl alcohol) or PGE (poly-diethanol), biological film forming agent can be xanthans or sugar ester, content is between the 1%-2 ‰ of total weight, all the other are water, evenly stir through normal temperature to form, and the water yield will be enough to the fruit submergence; Crisper adopts BOPS (biaxially oriented polystyrene) sheet material to press empty moulding, and handles through antifog anti-frosting; The thermal insulation carton is formed by the corrugated board moulding that the surface is covered with the plastics lamella or the ply of paper of aluminizing, can be to be covered with the plastics lamella in the one or both sides of corrugated board, the compound again white board (or boxboard) of going up of plastic sheet laminar surface, also can be to be covered with the ply of paper of aluminizing in the one or both sides of corrugated board, can also be to be coated with the ply of paper of aluminizing on the plastic sheet laminar surface again, compound and corrugated board production technology be composited by paper.
