Problems solved by technology

The latter, such as hydrogen peroxide, hypochlorous acid and its salts, peracetic acid, bleaching powder, etc., have a stronger bactericidal function than ordinary preservatives in their oxidation, and also have a bleaching function, but due to their unstable chemical properties, they are easy to Decomposition, may have adverse reactions with food ingredients or bring adverse effects on food, rarely added directly to food, mainly used for drinking water, as well as sterilization and disinfection of containers, tools, equipment and semi-finished products

Abstract

The invention relates to a food bactericide and a preparation method thereof. The food bactericide comprises the components in parts by volume: 0.05-0.40 part of glycerin fatty acid ester, 0.05-0.50 part of a grapefruit extract solution, 0.05-0.30 part of sodium citrate, 0.02-0.10 part of lactic acid and 90-105 parts of distilled water, the pH of the food bactericide is 3.0-6.0, and the food bactericide is prepared by mixing the components above; the food bactericide has efficient bactericidal and bacteriostatic effects on bacteria in food by a synergistic effect of all the components under the special pH condition; and the preparation method is simple and suitable for the demands of industrial production.

Description

technical field [0001] The invention relates to the field of fungicide production, in particular to a food fungicide and a preparation method thereof. Background technique [0002] Grapefruit, namely "Zhu Luan", also known as grapefruit, Rutaceae, originates from the West Indies. It can be used for garden planting and ornamental, and the fruit is edible and medicinal. Its grapefruit extract is light yellow crystalline powder, soluble in acetone, ethanol, hot acetic acid and hot water, insoluble in ether, hexane and chloroform. It belongs to dihydroflavone. Under alkaline conditions, the pyrone ring is cracked. After hydrogenation treatment, dihydrochalcone sweetener can be prepared. The sweetness is about 150 times that of sucrose. It has anti-inflammatory, analgesic, anti-viral, Bacteriostasis and inhibition of eye aldose reductase, can be used as an active ingredient of food fungicides. [0003] Food fungicides are a class of chemical agents that can prevent the reprodu...
