Embodiment 1

[0019] A modified atmosphere fresh-keeping packaging method for medlar, mainly completed by the following steps:

[0020] 1. Lycium barbarum packaging, the packaging bag is a composite film bag composed of kraft paper layer, aluminum foil layer and polyethylene layer from the inside to the outside;

[0021] 2. Fill the packaging bag with mixed gas, the mixed gas is N 2 95%, CO 2 5%.

[0022] 3. Lycium barbarum is used 60 Co-γ-ray radiation treatment;

[0023] The water content of the wolfberry is: 12%-22%

Embodiment 2

[0025] Step is identical with embodiment 1, and described mixed gas is N 2 97%, CO 2 3%;

Embodiment 3

[0027] Step is identical with embodiment 1, and described water content is 15%-18%, and mixed gas is N 2 97%, CO 2 3%;

[0028] Due to the implementation of the above technologies, while the kraft paper and aluminum foil are shading, the aluminum foil completely blocks the external moisture, and the polyethylene layer increases the toughness of the film bag, making the packaging better and safer; N 2 The chemical properties are inactive, and it is difficult to react with other substances at room temperature. It is a good filling protective gas to prevent the oxidation of wolfberry; CO 2 It can be dissolved in various fats or water to form weakly acidic carbonic acid, which can inhibit the activity of mold, spoilage bacteria and other microorganisms, thereby further protecting the wolfberry fruit and fundamentally preventing the "oily discoloration" of the wolfberry fruit.

Abstract

The invention provides a modified atmosphere packaging method for fructus lycii, and belongs to the field of food fresh-keeping. The modified atmosphere packaging method is mainly comprises the following steps: a, packaging fructus lycii, wherein a packaging bag is a composite membrane bag formed by compounding a kraft paper layer, an aluminum foil layer and a polyethylene layer; b, filling the packaging bag with mixed gas, wherein the mixed gas contains 95%-97% of N2 and 3%-5% of CO2; c, adopting <60>Co-gamma for radiation treatment; therefore, the modified atmosphere packaging method provided by the invention for fructus lycii is safe, efficient and long in storing time, and effectively prevents fructus lycii from moisture absorption and agglomeration, and oxidation discoloration.

Description

Technical field: [0001] The invention relates to a modified atmosphere fresh-keeping packaging method for wolfberry fruit, which belongs to the field of food preservation, and in particular to a modified atmosphere fresh-keeping packaging method for wolfberry fruit. Background technique: [0002] The main components of Lycium barbarum: ① Polysaccharides, complex polysaccharides composed of acidic heteropolysaccharides and polypeptides or proteins, are its active ingredients; ② Alkaloids: such as betaine (betaine); ③ Carotene; ④ Fatty acids; ⑤ Various free amino acids ; ⑥ Trace elements; Lycium barbarum polysaccharide rich in wolfberry is a water-soluble polysaccharide composed of six monosaccharide components: arabinose, glucose, galactose, mannose, xylose, and rhamnose, which have physiological activities. It can enhance non-specific immune function, improve disease resistance, and inhibit tumor growth and cell mutation. The phenomenon of oily smell will affect the efficac...
