Composite fruit powder with effect of regulating intestinal flora and preparation method of composite fruit powder

Abstract

The invention discloses composite fruit powder with an effect of regulating intestinal flora and a preparation method, longan, medlar and red dates are compounded according to a mass ratio of 4: 5: 1-3: 4: 1, and the composite fruit powder is prepared by the following steps: mixing dried longan, dried medlar and dried red dates according to a ratio, adding 60-80% ethanol, soaking for 8-12 hours, drying the dried longan, dried medlar and dried red dates at 50-70 DEG C for 8-12 hours, treating at 120-150 DEG C for 3-10 minutes for enhancing the aroma; and carrying out superfine grinding on the aroma-enhanced raw materials at 0-5 DEG C for 1-3 minutes to obtain the longan, medlar and red date composite fruit powder.

Description

technical field [0001] The invention belongs to the field of nutritious food production, and in particular relates to longan, wolfberry and jujube nutritious fruit powder capable of regulating intestinal flora and a preparation method thereof. Background technique [0002] Due to factors such as fast pace of life, high stress, and unbalanced dietary intake in modern people, the intestinal flora is often in an unbalanced state. The long-term imbalance of intestinal flora can induce various diseases, such as obesity and diabetes, which seriously affect human health. Therefore, changing the structure of intestinal flora through dietary nutrition and regulating intestinal homeostasis, so as to improve human health, has become a key development direction in the field of nutritional and healthy food research. [0003] Currently, nutritional and healthy foods for regulating intestinal flora are mainly based on adding functional prebiotics such as oligosaccharides. Some agricultur...

Problems solved by technology

There are some problems with the existing processing technology of the three raw materials: on the one hand, the existing processed products only stop at the simple two-by-two mixing and compounding of the raw materials for processing, and lack the synergistic effect of the active ingredients in the three raw materials On the other hand, because longan, wolfberry and jujube all have the characteristics of high soluble sugar content, high viscosity of raw materials, difficulty in direct milling, and easy moisture absorption and agglomeration of the prepared powder, the existing processing technology is mainly through Add drying additives to solve the above problems. The ratio of added additives to raw materials should be at least 1:1 to solve the above problems, but a large amount of additives will lead to problems such as reduced nutritional value of the product, weak flavor, and poor taste.
