Method for making sweet tangelo sericin polypeptide juice

Abstract

The invention relates to a method for making sweet tangelo sericin polypeptide juice. A novel juice product which is excellent in taste and rich in nutrition is produced from sweet tangelo pulp as the main raw material through the steps of: performing enzymolysis treatment and stabilizer adding treatment after juicing, and enabling the treated juice to be compatible with sericin polypeptide having physical properties such as excellent suspension property and the like and biological activity such as resistance to oxidation and the like obtained through special enzymolysis treatment. The method provided by the invention has the characteristics that deep processing of the sweet tangelo is performed in advance so that the debitterizing process is omitted; as a result, the cost is saved and the original flavor is also ensured; and the sericin polypeptide is added to the juice, so that the functions as a preservative and a stabilizer are achieved while the function as the juice nutrition component is realized; and therefore, addition of the artificial preservative is avoided. According to the invention, konjac glucomannan serves as the main body, while pectin and xanthan gum serve as an auxiliary complex, so that a compound stabilizer of natural polysaccharide is formed and has excellent effect; and therefore, the nutritional functions of the product are greatly improved.

Description

technical field [0001] The invention relates to a production process of sweet orange pomelo juice, in particular to a method for preparing sweet orange pomelo sericin polypeptide juice, which belongs to the technical field of fruit juice production. Background technique [0002] Sweet orange pomelo is a unique and precious fruit that grows in southern Zhejiang and northern Fujian. It is a hybrid of citrus pomelo bred from Hassuo pomelo as the male parent and Ueda Wenzhou citrus as the female parent.

Problems solved by technology

In recent years, farmers in southern Zhejiang and northern Fujian have begun to plant a large number of sweet oranges and pomelo, and some fresh fruits cannot be sold in time, which dampens the enthusiasm of fruit farmers.

At present, there is no processed product of sweet orange pomelo in the market except for the fresh fruit of sweet orange pomelo. Therefore, the demand for deep processing of this new type of fruit with increasing output is very urgent.
