Embodiment Construction

[0008] The present invention will be further described below in conjunction with embodiment.

[0009] The process of the present invention includes: 1) raw material acquisition and processing: purchase fresh eggplants from farmers or markets during the eggplant production season, remove the stems of the acquired eggplants, wash them with water, and then filter or dry them; 2) chlorination Sodium solution treatment: put filtered water or dried eggplants into the container, then add a sodium chloride solution with a concentration of 5%-6% by weight in the container, the amount of sodium chloride solution added is based on the total amount of eggplants. 3) Quick-freezing: after the container is filled with sodium chloride solution, put it into the freezer for quick-freezing and preservation. The added sodium chloride solution is a solution cooled to natural temperature, and the temperature of the freezer is controlled at minus 18°C ​​to minus 20°C. 4) Thawing: Thaw the quick-fro...

Abstract

The invention discloses a process of preserving egg plants by refrigeration, which comprises the steps as following: 1) the purchase and treatment of raw materials: the fresh egg plants are purchased from peasants or the market during the production season of the egg plants; after being removed the stalk, the purchased egg plants are cleaned by water and then filtered for removing the water or dried with air; 2) the sodium chloride solution treatment: the egg plants which are filtered with water removed or dried with air are put in a container, and then the sodium chloride solution with a weight percentage concentration ranging from 5 percent to 6 percent is added in the container; the sodium chloride solution is added in until the egg plants are completely immersed by the sodium chloridesolution; 3) quick freezing: after the container is filled up with the sodium chloride solution, the container is immediately put in a household freezer for preserving by refrigeration; 4) thaw: the egg plants after being rapidly frozen are thawed when being taken and used. The process of the invention can maintain the freshness of the egg plants for a longer time.

Description

technical field [0001] The invention relates to a fresh-keeping technology for fresh vegetables, in particular to a freezing and fresh-keeping technology for eggplant. Background technique [0002] After fresh eggplant is harvested, if it is not kept fresh, it can only be transported and sold for a short distance, otherwise, it will easily deteriorate. The characteristic that fresh eggplants are easy to deteriorate determines that in the season when eggplants are harvested intensively, it is easy to have a problem of selling them; while in other seasons, there is a problem of lack of supply of fresh eggplants. Contents of the invention [0003] The purpose of the invention is to design a kind of eggplant freezing and fresh-keeping technology. [0004] The present invention aims to solve the problem that fresh eggplants are difficult to sell in the eggplant harvest season, and there is a lack of supply of fresh eggplants in other seasons. [0005] In order to achieve the ...
