Problems solved by technology

The biggest disadvantage of sorbic acid is its low solubility, and its potassium salt is the most commonly used, but the price is more expensive, 80,000 yuan per ton
[0004] All preservatives allowed in my country's GB2760-96 have different selectivity to the intensity of bacteriostasis. For example, a preservative has high inhibitory intensity to Gram-positive bacte

Abstract

The invention discloses a high-activity compound biological preservative and a processing technology thereof. The compound biological preservative is prepared from a chelating agent, an antimicrobialagent, organic acid and an binder; the processing technology of the compound biological preservative comprises the steps that raw materials are weighed and dissolved into water to form a mixture, themixture is homogenized, spray drying is conducted, and the high-activity compound biological preservative is obtained. According to the compound biological preservative, all ingredients complement each other, the synergistic effect is achieved, not only is the bacteriostatic strength is enhanced, but also the bacteriostatic spectrum is added, the inhibiting effect on Gram-positive bacteria, Gram-negative bacteria and fungi is achieved, and the dosage of a single component antibacterial agent is greatly reduced; the experimental results show that the antibacterial and antiseptic effects of thecompounded biological preservative is better compared with a single component preservative.

Description

technical field [0001] The invention relates to the technical field of preservatives, in particular to a highly active compound biological preservative and its processing technology. Background technique [0002] Microbial contamination is one of the main factors affecting food safety. The function of preservatives is to kill or inhibit the growth and reproduction of microorganisms to prevent tissue infection and biological corruption of substances. During the production and circulation of food, it will be spoiled due to microbial contamination, and the addition of preservatives is necessary. However, the random inspection of food frequently has problems with preservative items or microbial indicators, and excessive use and addition of preservatives that are prohibited for food The situation has been repeatedly banned. [0003] The food preservatives currently produced in my country are mainly benzoic acid and sorbic acid, of which benzoic acid accounts for 90%. In order t...
