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: buy 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 eggplant 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 the eggplant. 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-frozen...

Abstract

The invention discloses a process for freezing and keeping fresh eggplants. The process includes: 1) Acquisition and processing of raw materials: 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 them. water or dry; 2) sodium chloride solution treatment: put filtered water or dried eggplant into the container, and then add a sodium chloride solution with a concentration of 5%-6% by weight in the container to chlorinate The amount of sodium solution added is until the eggplant is completely submerged; 3) Quick freezing: After filling the container with sodium chloride solution, immediately put it into the freezer for quick freezing to keep fresh; thaw. The invention can keep the freshness of the eggplant for a long 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. 【Content of 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...
