Novel casing salt and preparation method and application thereof

Abstract

The invention belongs to the field of the light industry, and particularly relates to a novel casing salt and a preparation method and application thereof. According to the novel casing salt, sodium chloride is used as a main raw material, a specific phosphate combination is added, a mass ratio of trisodium phosphate (Na<3>PO<4>) to disodium phosphate (Na<2>HPO<4>) in the specific phosphate combination is 1: 1 to 1: 4, and ball-milling mixing is adopted. The casing salt is used in the stages of salting, preserving, storing and transporting of casings. The novel casing salt accounting for 10-50% of the mass of casings is added into raw casing materials, semi-finished casing products and finished casing products for salting, or the raw casing materials, semi-finished casing products and finished casing products are soaked into saturated casing bittern with a pH value of 7.0-10, so antimicrobial problems of traditional casing salts are solved, the mechanical properties of natural casingsare obviously improved, the elasticity and toughness of the casings are enhanced, and favorable color protection effect is obtained. Phosphate used in the invention is low in cost and guarantees foodsafety when used as a food additive in natural casing products.

Description

technical field [0001] The invention belongs to the field of light industry, and in particular relates to a novel casing salt and its preparation method and application. Background technique [0002] Table salt has been used to preserve natural casings for thousands of years. Casing salt is refined from sea, lake, well and mine salt and used for casing processing. At present, the demand for casings in the international market is very large, and it is showing a trend of gradual growth. Its consumer market is mainly concentrated in developed countries and regions such as Europe, North America and Japan. On the one hand, consumers in developed countries advocate natural consumption concepts, which provides space for the development of the casing industry. On the other hand, these countries have very high requirements for product quality, and the scraping, processing and transportation of raw animal intestines There will be microbial cross-infection and bacterial growth, affec...

Problems solved by technology

On the one hand, consumers in developed countries advocate natural consumption concepts, which provides space for the development of the casing industry. On the other hand, these countries have very high requirements for product quality, and the scraping, processing and transportation of raw animal intestines There will be microbial cross-infection and bacterial growth, affecting the sensory quality and product quality of casings, causing irreparable losses to casing processing enterprises, and making the external environment for casing export increasingly severe
