Embodiment 1

[0016] 1 kg of noodle soup, dehydrated so that the water content of the food is 8%, is sterilized by ultraviolet rays and divided into two parts A and B equally. Prepare 40ml, 0.5mol / l Hcl solution and pour it into A portion of food for airtight packaging, prepare 20ml.1mol / l NaoH solution and pour it into B portion of food for airtight packaging. Half a year later, the food A and B were disassembled and mixed, poured into boiling water for consumption, the taste was delicious, and the food did not deteriorate.

[0017] 1 kg of white radish, boiled and sterilized, divided into two parts A and B, prepared 50ml, poured 1mol / l vinegar into food A and sealed the package, 50ml 1ml / l Na 2 CO 3 Pour it into the food of part B and seal the package. After 3 months, disassemble the food of part A and B and mix it, pour it into boiling water and eat it. The taste is delicious and the food has not deteriorated.

Abstract

The present invention discloses method of preserving food with strong acid and strong alkali based on the principle that most bacteria can not survive in strong acid or strong alkali. The food preserving method includes sterilization of food, dewatering, dividing the food into two parts, soaking one part in acid solution and the other in alkali solution, and hermetically packing. Before the food is eaten, the two parts are neutralized to make the food become neutral and harmless and water flushed. The present invention has simple operation, convenient preservation and long preserving time.

Description
