Abstract

A convenient refrigerant for food is prepared from water and one or two of organic acid and alkali-metal carbonate. Its advantages are high effect, low cost and no poison and damage to human body.

Description

Technical field: [0001] The invention relates to a refrigerant, in particular to a food-convenient refrigerant for instant food. Background technique: [0002] Although there are several kinds of refrigerants that can be cooled by dissolving in water, most of them are harmful to the human body and cannot directly contact with food. Or it is applicable to a small amount of refrigerant that is in direct contact with food and beverages and must be stirred before being dissolved in water, which is extremely inconvenient to use. Invention content: [0003] The invention solves the above-mentioned defects in the prior art, and provides a non-toxic and harmless food-convenient refrigerant with a large cooling range. [0004] The technical scheme of the present invention is as follows: it includes the following materials: one or both of organic acid and alkali metal carbonate, and water. [0005] Compared with the prior art, the present invention has the characteristics of non-t...
