Abstract

A preparation method of thermally irreversible gel protective film of bird's nest and its application in the processing of fruity bird's nest beverage. After mixing the hot solutions in equal proportions (or using curdlan, sodium alginate and other thermally irreversible gels as raw materials), put the stewed and drained bird's nest into soaking for 15-30 minutes, remove and cool (cool at room temperature, dry with cold wind) , ice water bath, etc.) to form a heat irreversible gel protective film; the weight composition of the fruity bird's nest drink is: bird's nest 0.3%~1.5%, fruit juice 3%~15%, sweetener 3%~8%, acidity regulator 0.005%~0.2%, thickener 0.09%~0.15%, essence 0.1%~0.3%. The present invention applies the thermally irreversible gel to the processing of the bird's nest beverage, which not only helps to maintain the appearance and taste of the bird's nest, but also has good flavor and color, is sweet and sour, and is suitable for all ages.

Description

technical field [0001] The invention relates to the field of bird's nest processing, in particular to a method for preparing a thermally irreversible gel protective film of bird's nest and its application in processing fruity bird's nest beverages. Background technique [0002] Bird's nest is a traditional nourishing food in our country. It has many functions and is sought after by consumers. At present, common commodity forms include dried bird's nest, fresh stewed bird's nest, instant bird's nest, etc., and the price is relatively expensive. With the advancement of food processing technology and the improvement of people's living standards, consumers have more requirements for the diversity, convenience and price of bird's nest products. At present, the development of bird's nest beverages has become a research hotspot for bird's nest processors. Therefore, the development New, multi-taste bird's nest drinks have become the general trend. However, due to the characterist...
