Embodiment Construction

[0025] 0.5 grams of sorbic acid C for fresh corn on the cob at room temperature 6 h 8 o 2 , 10 g sodium benzoate C 7 h 5 o 2 Na, 2 g citric acid C 6 h 8 o 7 , 0.5 g sodium metabisulfite Na 2 S 2 o 5 , 100 mg vitamin B 1 , add 1000 ml of water in sequence, and become a colorless and transparent preservative solution after fully dissolving. After the fresh corn cobs are soaked for ten minutes, they are immediately put into a high-temperature-resistant peritoneal polypropylene bag, evacuated, and then put into a sterilizing pot to complete. Its color, fragrance, taste and shape will not change after being kept fresh at room temperature for 18 months.

Abstract

Disclosed is a fresh-keeping method for corn in normal temperature which comprises, (1) confirming breed and purchasing based on standard, (2) debarking and cutting head, washing with clean water, (3) fresh-keeping in bags, vacuum-pumping, (4) measuring and loading into cooking pot, closing the door, (5) elevating temperature while keeping the pressure unchanged, (6) keeping constant temperature, (7) sterilizing and quit heat supply, (8) cooling down and lowering the pressure, blasting the bags, (8) water inflowing for cooling down, so as to keep the pressure constant.

Description

technical field [0001] The invention relates to a method for keeping fresh corn cobs fresh at room temperature. Background technique [0002] After China's accession to WTO, the deep processing industry in the fields of agricultural by-products and food urgently needs to apply fresh-keeping technology, but this field is still in its infancy in China. At present, there are many fresh-keeping technologies at home and abroad, and different means such as low-temperature freezing, constant temperature, high pressure, radiation, coating, nitrogen filling, and controlled atmosphere are generally adopted to achieve the purpose of fresh-keeping. However, these fresh-keeping technologies have high cost and large investment, and cannot be stored at room temperature for a long time, which brings difficulties to the storage, transportation, shelf life and consumption period, and is not conducive to the field of deep processing of agricultural and sideline products.
