Abstract

The present invention relates to a Chinese evergreenchinkapin seed soft can and a processing method thereof. The method comprises steps of: peeling fresh Chinese evergreenchinkapin seed; using kernel of the Chinese evergreenchinkapin seed with inner coat removed as a raw material; employing reduced pressure infiltration to protect color; vacuumizing and carrying out ultra high pressure modification treatment; and cooking and cooling to obtain a finished product. The method provided by the invention realizes penetration of a protective color liquid into the Chinese evergreenchinkapin seed kernel, and effectively avoids a browning phenomenon during the processing procedure and the shelf period; ultra high pressure modification prevents the product from turning back to a raw state, and has advantages of simple processing technology, and beautiful color, good flavor, and premium taste of the product.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a chestnut soft can and a processing method thereof. Background technique [0002] Soft cans are bagged foods that can be stored for a long time and are made of high-temperature resistant retort bags made of polyester, aluminum foil, polyolefin and other film composite packaging materials as packaging containers, and sealed and sterilized. Soft cans have the advantages of high-temperature sterilization, long-term storage, light weight, easy to carry, easy to open, convenient to eat, etc., and are very popular among consumers. [0003] Chestnut contains starch, soluble sugar, protein, fat, vitamin C, minerals and amino acids. It is rich in 17 kinds of amino acids, and the content of 7 kinds of essential amino acids accounts for more than 20% of the total amino acid content. It has outstanding nutrition and functionality. It is sweet and non-toxic, and has the effects of...
