Embodiment Construction

[0015] A vacuum air-conditioning fresh-keeping process for fresh lily scales is formed by fresh-keeping and storing fresh lily raw materials, then performing fresh lily pretreatment and vacuum air-conditioning treatment, and finally packaging them into vacuum bowls. The specific process steps are as follows:

[0016] (1) Fresh-keeping storage of fresh lily raw materials: select fresh lily raw materials, select fresh and high-quality fresh lily raw materials, and then send them to fresh lily storage warehouses for storage at a temperature of -2°C to 0°C;

[0017] (2) Fresh lily pretreatment: peel and remove the fresh lily raw materials after fresh storage, and then screen the fresh lily flakes, then use sterilized water to clean and drain the fresh lily flakes, and then air-dry them deal with;

[0018] (3) Vacuum air-conditioning: first use ultraviolet rays to sterilize the polypropylene composite bowl, and then put the fresh lily strips into the polypropylene composite bowl, a...

Abstract

The invention discloses a vacuum air-adjusting preservation process for fresh lily scales. The vacuum air-adjusting preservation process comprises the following steps: carrying out preservation storage treatment on a fresh lily raw material; carrying out pretreatment and vacuum air-adjusting treatment on the fresh lily raw material; and finally sealing into a vacuum bowl. According to the process, by virtue of a vacuum air-adjusting fresh keeping technique, the fresh lily raw mateiral is in a gas environment with low oxygen and high nitrogen; the metabolism speed of the fresh cut lily can be further inhibited and the respiration intensity is lowered; and oxidation of the fresh cut lily surface and reproduction of bacteria can be controlled, so that the refreshing time of the fresh cut lily is prolonged to about 15-20 days; meanwhile, by virtue of a polypropylene composite bowl, the vacuum air-adjusting preservation process has good heat sealability and simultaneously has certain gas permeability, so as to keep the gas environment in package in balance within 10 days; by virtue of the package, the fresh cut lily can be effectively protected in the air-adjusting environment which is beneficial to preservation; and squeeze damages in the transport process are avoided.

Description

technical field [0001] The invention relates to the technical field of food fresh-keeping, in particular to a vacuum air-conditioning fresh-keeping process for fresh lily scales. Background technique [0002] In recent years, with the acceleration of the pace of urban life, the changes in the living and consumption habits of the urban population and the level of consumption [0003] As a fashionable consumer product, clean vegetables that are convenient, fast, safe and pollution-free are becoming more and more popular among consumers; at the same time, consumers have higher and higher requirements for freshness of clean vegetables. Coupled with the national agricultural departments at all levels paying attention to how to reduce the loss of agricultural products and the advancement of the convenience project of vegetable baskets, and the health department's attention to food hygiene and safety, the research and development of clean vegetable preservation techniques and key t...
