Problems solved by technology

[0003] Natamycin is usually prepared with an alcohol solution to spray or soak the surface of food. However, natamycin is insoluble in ethanol and water and can only be prepared as a suspension during use. It must be stirred frequently during use.
This process is usually difficult to control. Natamycin is prone to sedimentation during use, resulting in high concentration in the lower layer, and even only alcohol in the upper layer.
Then there are two extreme situations, either the natamycin is too large and the preservative exceeds the s

Embodiment Construction

[0018] In order to make the technical solution of the present invention more clearly expressed, the present invention will be further described below.

[0019] The invention provides a food preservative used as a food additive. The food preservative is in powder form. The food preservative includes natamycin and an acidic substance, and the natamycin and the acidic substance form the base material of the food preservative , the mass percent of the natamycin and the acidic substance is (0.0005~2.333): 1, preferably, the mass percent of the natamycin and the acidic substance is (0.163~1): 1; the acidic substance Used to adjust the pH value of food preservatives dissolved in alcohol, the acidic substances can be citric acid, fumaric acid, malic acid, tartaric acid, adipic acid, ascorbic acid, D-isoascorbic acid, glutamic acid, glycine, gluconic acid - a mixture of one or more components of acids such as delta-lactones.

[0020] Preferably, the food preservation agent also includ...

Abstract

The invention discloses a food preservative. The food preservative is used as a food additive, and includes natamycin and an acidic material. A base material of the food preservative is composed of the natamycin and the acidic material and the mass percent ratio between the natamycin and the acidic material is (0.0005-2.333):1. The food preservative provided by the invention has the characteristics of good solubility in ethyl alcohol, high stability, a wide antimicrobial spectrum and high activity. Meanwhile, the food preservative is easy to use and effectively inhibits various kinds of microorganisms like mould, bacteria, and yeast, so as to guarantee food quality and prevent food from growing mould, meet the requirements of food preservation and freshness maintenance and meet the demands of people on food safety.

Description

technical field [0001] The invention relates to a food additive, in particular to a food fresh-keeping agent. Background technique [0002] Natamycin is a natural, broad-spectrum, efficient and safe inhibitor of filamentous fungi such as yeast and mold. It can not only inhibit fungi, but also prevent the production of mycotoxins. Natamycin is harmless to the human body, it is difficult to be absorbed by the human digestive tract, and it is difficult for microorganisms to develop resistance to it. At the same time, because of its low solubility, it is usually used for surface preservation of food. Natamycin is currently the The only anti-fungal microbial preservative in the world. [0003] Natamycin is usually prepared with an alcohol solution to spray or soak the surface of food. However, natamycin is insoluble in ethanol and water, and can only be prepared as a suspension during use, and it must be stirred frequently during use. This process is usually difficult to contro...
