Abstract

A preparation method and application of a melanin fermentation product of Mycocystis coronoidis. In the present invention, S. coronis is used as a fermentation strain, and a fermented product with high melanin content is prepared through a specific liquid fermentation medium formula, and the fermentation product includes S. coronis melanin fermentation liquid and a concentrate thereof. The melanin fermentation product has the characteristics of wide pH adaptation range, strong thermal stability, long-term storage under natural light, and no fading. The melanin fermentation product can be used for coloring Changsha stinky tofu blanks, and can also be widely used in medium and low-acid foods such as beverages, jellies, and candies with a pH>4.5, as well as fuel consumption and sauce products.

Description

A kind of preparation method and application of R. coronoides melanin fermentation product technical field The invention belongs to microbial fermentation and food field, be specifically related to a kind of R. coronoides melanin fermentation product, Its preparation method and application. Background technique Melanin has important purpose in food processing, and various foods such as beverage, jelly, biscuit and ice cream and sauce system In the production process of spices, oyster sauce and other condiments, melanin must be used to meet the sensory needs of consumers. some other special Flavored foods, such as my country's traditional specialty snack Changsha stinky tofu, are mainly characterized by their black color as the main feature recognized by consumers. At present, the most commonly used melanin in food is caramel color, but caramel color is easy to precipitate and has a burnt smell, which limits its color. The scope of use; and the caramel color contai...
