Abstract

The invention relates to the technical field of package and in particular relates to a gas-filled packaging method for retaining the freshness of cherries. According to the invention, a composite controlled-atmosphere packaging method is adopted, wherein air in a packaging box or packaging bag is replaced; the packaging box or packaging bag is made from a low-barrier film; and the controlled-atmosphere gas consists of 5-8% carbon dioxide (CO2), 82-87% nitrogen (N2) and 8-10% oxygen (O2). The packaging box or packaging bag is sealed after air in the packaging box or packaging bag is replaced, and then stored at a temperature of 0-4 DEG C. The gas replacing rate is over 99.8%, and the error rate of the freshness retaining gas mixing accuracy is less than 1.5%.

Description

A kind of fresh-keeping cherry gas flush packaging method
 
Technical field
The present invention relates to the packing technique field, concretely, relate to a kind of fresh-keeping cherry gas flush packaging method.
Background technology
At present, commonly used fresh-keeping (or guaranteeing the quality) method of food mainly is: (1) fresh chemically; (2) freeze preservation; (3) vacuumizing high-temperature sterilization guarantees the quality; (4) vacuum nitrogen filling is fresh-keeping; (5) compound controlled atmosphere; (6) natural biological is fresh-keeping.In above-mentioned six kinds of fresh-keeping (guaranteeing the quality) technology, fresh chemically is to utilize the chemicals antiseptic and inhibiting bacteria function, but the customer is restricted because of paying close attention to the anti fouling composition secondary action; The shortcoming of freeze preservation is that the mouthfeel taste changes behind the food product refrigeration; The shortcoming that vacuumizes high-temperature sterilization is that distinctive taste, mouthfeel, the nutrition to food destroys bigger; Nitrogen-filled packaging can keep mouthfeel, taste and the nutrition of food preferably, but freshness date is very short, prolongs storage period like need and then need pack the back high-temperature sterilization, and the mouthfeel taste changes bigger.Compound controlled atmosphere is the brand new preservation technique that on above-mentioned traditional basis, grows up; Pack environment there is certain requirement; Be characterized in need not high-temperature sterilization; Thereby compound controlled atmosphere can guarantee mouthfeel, taste and the nutrition of original food, really guaranteed Normal juice, original flavor, the original appearance of food.
Cherry is divided into following five processes on the packing and storing method: pluck cherry--cleans to drench and does--gas flush packaging--sterilization processing--fresh-keeping warehouse storage.
Summary of the invention
In view of the prior art defective, the purpose of this invention is to provide a kind of compound controlled atmosphere cherry gas flush packaging method.
The technical scheme that the present invention adopts is following: the present invention adopts compound fresh-keeping method of modified atmosphere packing; Air in packing box or the packaging bag is replaced; Low Obstruct membrane is adopted in packing box or packaging bag, and controlled atmosphere gas is made up of CO2 (CO2), nitrogen (N2), oxygen (O2).The concentration of CO2 (CO2) is that the concentration of 5%-8%, nitrogen (N2) is 82%-87%, oxygen (O2) 8%-10%, after being replaced, the air in packing box or the packaging bag seals, and be to store under 0-4 degree in temperature.The gas replacement rate reaches more than 99.8%, and fresh-keeping gas mixed-precision percentage error is less than 1.5%.
The invention has the advantages that: CO2 gas has the effect that suppresses most of putrefactivebacterias and fungus growth breeding, is the main antipathogenic composition in the atmosphere gas; O2 has most of anaerobism putrefactivebacteria growth and breedings of inhibition, keeps the fresh meat color and luster and keeps fresh fruit of vegetables aerobic respiration, keeps the effect of freshness; N2 is a unreactable gas, and is inoperative with food, as blanketing gas, forms composite fresh-keeping gas with CO2, O2 and special gas.
The specific embodiment
The present invention adopts compound fresh-keeping method of modified atmosphere packing, and the air in packing box or the packaging bag is replaced, and low Obstruct membrane is adopted in packing box or packaging bag, and controlled atmosphere gas is made up of CO2 (CO2), nitrogen (N2), oxygen (O2).The concentration of CO2 (CO2) is that the concentration of 5%-8%, nitrogen (N2) is 82%-87%, oxygen (O2) 8%-10%, after being replaced, the air in packing box or the packaging bag seals, and be to store under 0-4 degree in temperature.The gas replacement rate reaches more than 99.8%, and fresh-keeping gas mixed-precision percentage error is less than 1.5%.

Claims (1)

1. fresh-keeping cherry gas flush packaging method; It is characterized in that: the present invention adopts compound fresh-keeping method of modified atmosphere packing, and the air in packing box or the packaging bag is replaced, and low Obstruct membrane is adopted in packing box or packaging bag; Controlled atmosphere gas is made up of CO2 (CO2), nitrogen (N2), oxygen (O2); The concentration of CO2 (CO2) is that the concentration of 5%-8%, nitrogen (N2) is 82%-87%, oxygen (O2) 8%-10%, after being replaced, the air in packing box or the packaging bag seals, and be to store under 0-4 degree in temperature; The gas replacement rate reaches more than 99.8%, and fresh-keeping gas mixed-precision percentage error is less than 1.5%.
