Controlled-atmosphere fresh-keeping packing method for honey peaches

Abstract

The invention relates to the technical field of fresh-keeping packaging, in particular to a controlled-atmosphere fresh-keeping packing method for honey peaches. The method comprises the following steps: step 1, selecting materials; step 2, conducting cleaning and soaking: cleaning honey peaches before preservation, soaking the honey peaches in 1% NaClO solution for 5-10minutes, and then further soaking the honey peaches in a fresh-keeping liquid for 30-50min; step 3, conducting drying; step 4, soaking the dried honey peaches in brine, and airing the soaked honey peaches; and step 5, conducting gas filling and packaging: putting the air-dried honey peaches into a composite fresh-keeping bag filled with an ethylene absorbent, filling the fresh-keeping bag with a barrier gas, and sealing thebag, wherein the barrier gas is a mixture of nitrogen, carbon dioxide and helium. The method can effectively maintain the delicious taste of the honey peaches, has simple implement conditions, is suitable for batch production, has low requirements for storage conditions, and reduces the cost of production and transportation.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping packaging, in particular to a modified-atmosphere fresh-keeping packaging method for juicy peaches. Background technique [0002] Because peaches are rich in nutrition, they not only have nutritional value, but also have very good medicinal value. They are sweet, sweet, and juicy, so they are very popular among people, especially for the elderly and people with bad teeth. However, due to its own characteristics, peaches are susceptible to pests and various pathogens and rotting bacteria, and are not easy to store, thus affecting their commercial value. Effective fresh-keeping and storage are a worldwide problem. At present, under normal temperature and high temperature conditions, there is no good technology at home and abroad to effectively preserve the freshness of juicy peaches. [0003] At present, there are many reports on the commonly used fresh-keeping methods of juicy peaches, which...

Problems solved by technology

[0003] At present, there are many reports on the commonly used fresh-keeping methods of juicy peaches, which are chemical methods (such as coating treatment), but chemical methods, but the fresh-keeping effect is greatly affected by temperature and humidity; the fresh-keeping effect of ozone in cold storage is not ideal; The concentration of ozone has harmful effects on people, and there is also a low-temperature storage method, which can effectively inhibit the post-ripening softening and rot of peach fruits. However, peaches are cold-sensitive fruits. If the temperature is too low, cold damage symptoms will appear, mainly manifested as pulp browning, Lignification or flocculation, reduction of juice, abnormal post-ripening and loss of flavor, etc.
