Abstract
The invention belongs to the technical field of food packaging, in particular to a nitrogen-charged packaging method. According to the nitrogen-charged packaging method, selection of the vacuumizing degree and the quantity of charged nitrogen changes intelligently along with the weights of contents in packages, the main embodiment lies in that under the condition that the weights of products in packaging bags are different, the numerical value of the vacuum degree switching point corresponding to vacuumizing and the numerical value of the nitrogen switching point for nitrogen charging can change, and specifically, when the weight of the product in each packaging bag is 4-6 g, the vacuum degree is 0.08-0.12 MPa, and the quantity of charged nitrogen is 7-9 MPa. In this way, the packaging stability of the products is guaranteed, and the problem that the quantity of charged nitrogen is difficult to adjust and control when irregular food is packaged is solved; and airtightness of the packaging bags is better guaranteed, the original flavor of the products is maintained, the shelf life of the products is prolonged, and oxidization of greases and the like is restrained.
Description
Technical field
The invention belongs to Food Packaging technology field, and in particular to nitrogen-filled packaging method.
Background technology
In food service industry, such as various cooked such as chicken leg, ham, sausage, seasoned, oxen fresh-keeping in order to be carried out to food
Jerky etc., for example various pickles of curing food and bean product, preserved fruit etc., more and more widely using vacuum packaging, by vacuum packet
Dress reduces oxygen content in packaging, prevents the Biodeterioration of packaged food, keeps the color, smell and taste of food, and extends the shelf life.But
It is " dead angle " occur in traditional vacuum packaging packaging bag, causes the breeding of storage growth of aerobic microorganisms, Oxidation of Fat and Oils, food
The problems such as product are putrid and deteriorated；And easily there is product crimp, and outward appearance shrinkage phenomenon.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of nitrogen-filled packaging method, and the method is comprised the following steps：Take out
Vacuum, nitrogen charging, Quick seal, cooling；In the vacuum step, vacuum changes with packing content amount of substance；It is described to fill
In nitrogen step, nitrogen charging amount changes with packing content amount of substance.
Wherein, in above-mentioned nitrogen-filled packaging method, the vacuum changes with packing content amount of substance and shows as：In packaging
Tolerant quality is 4~6g/ bags, and it is 0.08~0.12MPa to vacuumize corresponding vacuum switching point.
Wherein, in above-mentioned nitrogen-filled packaging method, the nitrogen charging amount changes with packing content amount of substance and shows as：In packaging
Tolerant quality is 4~6g/ bags, and nitrogen charging amount is 7~9MPa.
Wherein, in above-mentioned nitrogen-filled packaging method, nitrogen displacement rate is up to more than 99.9%.
The beneficial effects of the invention are as follows：
(1) the method is used and first vacuumized, then inflated with nitrogen, and nitrogen displacement rate is high, up to more than 99.9%；
(2) with pack content amount, intelligence changes for the selection of suction and nitrogen charging amount, it is ensured that the packaging of product is steady
It is qualitative, when solving irregular packaging for foodstuff nitrogen charging amount be difficult to regulation and control the problems such as；
(3) product quality is ensured：Compared with traditional vacuum is packed, nitrogen-filled packaging technology is mainly by vacuumizing, quick,
Remaining oxygen in packaging is greatly reduced, nitrogen charging, Quick seal, cooling is then carried out, the sealing of packaging bag is better assured that,
The original local flavor of product is maintained, shelf life of products is extended, and inhibit the oxidation of grease etc.；
(4) attractive packages degree is ensured：Nitrogen is practically insoluble in water and oil, and food is to nitrogen substantially without absorption, therefore nitrogen charging
The packaging of gas will not be deflated, it is ensured that the aesthetic property of packaging for foodstuff.Avoid swelling for packaging bag volume during food sterilization
Cause permanent deformation, also will not as vacuum packaging occur product crimp, and outward appearance shrinkage phenomenon.
Specific embodiment
The invention provides a kind of nitrogen-filled packaging method, the method is comprised the following steps：Vacuumize, nitrogen charging, Quick seal,
Cooling；In the vacuum step, vacuum changes with packing content amount of substance：Packing content amount of substance is 4~6g/ bags,
It is 0.08~0.12MPa to vacuumize corresponding vacuum switching point；In the nitrogen charging step, nitrogen charging amount is with packing content material
Measure and change：Packing content amount of substance is 4~6g/ bags, and nitrogen charging amount is 7~9MPa.
Wherein, in above-mentioned nitrogen-filled packaging method, nitrogen displacement rate is up to more than 99.9%.
Wherein, above-mentioned nitrogen-filled packaging method, it is because inventor has found through test of many times that selection is filled with nitrogen：
1. the air during nitrogen excludes packaging for foodstuff is filled with, anaerobic environment is built, greatly suppresses the microorganisms such as bacterium, mould
Growth and breeding, extend food shelf-life；
2. nitrogen is filled with, the oxygen content in packaging is reduced, the pace of change of food peroxide value is significantly reduced, is effectively delayed
Food browning degree, so as to prevent the oxidation of grease in food, natural pigment, micronutrient, the oxidation for slowing down food becomes
Matter, colour fading and rotten change, keep the original color, smell and taste of food, improve food quality, reach food fresh keeping purpose；
3. nitrogen colorless and odorless, chemical property is lazy, not with food chemically reactive, and is not absorbed by food, and nitrogen
The specific physical property of gas is different from preservative treatment chemically, will not leave behind any residue, and security is very high；
4. nitrogen is filled with packing can well prevent the attrition crushing of food, food from bonding or cuddling up in a heap, and keep food
The advantages of geometry of product, dry, crisp, color, fragrance.
Wherein, in above-mentioned nitrogen-filled packaging method not specified (NS) part, be this area routine operation.
The present invention is further explained and is illustrated with reference to embodiments, but and be not so limited protection model of the invention
Enclose.
