Red bayberry preservation method

Abstract

The invention discloses a red bayberry preservation method comprising the following steps of: firstly, picking up red bayberries; secondly, selecting fruits; thirdly, sterilizing a storehouse and a container; and fourthly, precooling, grading, refrigerating and packaging, wherein the packaging operation is carried out by using a method for preserving red bayberries through filling nitrogen gas in vacuum, which comprises the following steps of: (1) basketing, extracting air and filling air; placing precooled red bayberries into a plastic basket, covering the plastic basket, then, sleeving a preservation pouch, extracting air in the pouch by using air extraction equipment, then, filling pure nitrogen gas, next, sealing the pouch, and then placing the pouch into a foam box; (2) placing a purchased dry ice-cream brick in the middle of the foam box; and (3) boxing: covering a lid of the foam box, sealing a seam by using viscose paper, fixing the lid, and placing the sealed foam plastic box into an external paper packaging box. By using the red bayberry preservation method provided by the scheme, the red bayberries can be kept non-toxic and harmless, long in preservation period and firm in packaging on the premise that the tastes of the red bayberries are not changed, and damaging a package and a product can be avoided in the transportation process.

Description

technical field [0001] The invention relates to an improvement of a fresh-keeping method for red bayberry, in particular to a method that does not change the taste of red bayberry, is non-toxic and harmless, has a long fresh-keeping period, and has firm packaging to avoid damage to the packaging and products during transportation. Background technique [0002] At present, there are a variety of technologies used to preserve bayberry on the market, which can be roughly divided into the following categories: temperature-controlled preservation technology, modified atmosphere preservation technology, chemical preservation technology, coating preservation technology and radiation preservation technology. The temperature-controlled fresh-keeping technology is mainly to place ice packs or ice cubes in the foam fresh-keeping box to achieve the effect of cooling and fresh-keeping. The main defects are that the fresh-keeping time is not long, the fresh-keeping effect is not good, and ...

AI Technical Summary

Problems solved by technology

To delay fruit ripening and aging, its defect is mainly that there are potential safety hazards and cause harm to the human body

The modified atmosphere preservation technology is mainly the plastic box-type modified atmosphere storage method. The plastic box-type modified atmosphere storage method refers to the combination of cold storage and spontaneous modified atmosphere preservation boxes to achieve fresh-keeping effects. The main defect is that the packaging is simple and damaged during transportation. suitable for long distance transportation
