Abstract

The invention discloses a thymol composite biological coating preservative and a preparation method and application thereof. Every 1000 ml of thymol composite biological coating preservative contains0.05-0.075 g of polysaccharide, 0.05-0.1 g of calcium stearoyl lactylate, 0.05-0.1 g of thymol microcapsules and the balance water. An edible coating film prepared by the method is good in wettabilityand solubility and low in viscosity, and can uniformly coat the surface of a fruit after preharvest spraying to form a uniform and continuous film.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a thymol composite biological coating preservative and its preparation method and application. Background technique [0002] Blueberry is the second largest berry in global trade after strawberry. The fresh fruit is blue and covered with a layer of white powder. The pulp is delicate and unique in flavor. It is rich in anthocyanins and other physiologically active substances. It is popular all over the world because of its various health functions. . In recent years, both domestic and foreign supply and consumption have been increasing year by year, among which the production and consumption in Asia have the fastest growth, especially in China. Since my country's blueberry entered the industrialized development in 2000, the output has doubled, and it has become a new type of fruit industry with rapid development. In 2017 alone, the national blueberry cultiv...
