Abstract

The invention relates to a preparation method of blueberry and roselle composite instant-dissolvable powder including prebiotics. The preparation method includes following steps: preparing pulp, performing enzymolysis, preparing juice, preparing roselle juice, performing a mixing process and a concentrating process, adding the prebiotics, and performing filtration, a freezing process and a packaging process. In the invention, an instant-dissolvable fruit powder is prepared with cooperative use of the three healthy foods: blueberry, roselle and the prebiotics, so that the instant-dissolvable powder is richer in mouthfeel and nutritional value. Organic acids in the blueberry fruits and roselle calyxes have antibiotic effects and have functions of reducing a pH value of digested substances and improving secretion of pancreas. Fructo-oligosaccharide is a natural active substance and is a novel sweetening agent which has health-caring functions of regulating intestinal flora, reproducing bifidobacterium, promoting absorption of calcium, regulating blood fat and immune system, resisting dental caries and the like. During the preparation process, by means of the preparation method, damages on vitamins and organic substances are reduced as far as possible so that nutritional value of the instant-dissolvable powder is ensured to loss as less as possible. The instant-dissolvable powder can be dissolved in water at low temperature and is wider in application.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of prebiotic blueberry roselle compound instant powder. Background technique [0002] Both blueberry fruit and roselle calyx are rich in organic acids and anthocyanins. Organic acids can directly affect its sensory quality, and at the same time have a protective effect on anthocyanins and other substances. Anthocyanins are the most effective free radical scavenger found so far, and their anti-free radical ability is 20 times that of vitamin C and vitamin E. 50 times. In addition, anthocyanins have the effects of protecting eyes, preventing cerebral thrombosis, delaying brain aging, and improving Parkinson's symptoms. [0003] Prebiotics refer to substances that can promote the growth and reproduction of probiotics, clean the intestinal tract through probiotics, and benefit the health of the host. [0004] In the prior art, the research and utilization of blu...
