Preparation method of banana powder with laxative and weight-reducing functions

Abstract

The invention discloses a preparation method of a banana powder product with functions of relaxing bowel and losing weight. The product is mainly prepared from whole banana powder and banana resistant starch in different ratio. The production method comprises the following steps of: preparing mature bananas with full yellow skin into the whole banana powder by the steps of peeling, color protection, pulping, vacuum freeze drying and the like; and preparing raw bananas with dark green skin into the banana resistant starch by the steps of peeling, pulping, enzymolysis, drying with a heat pump and the like. The whole banana powder has fragrant and sweet mouthfeel and has the function of relaxing bowel; the banana resistant starch has no smell or no taste, and has the functions of increasing satiety and losing weight; and the whole banana powder and the banana resistant starch can be blended and taken in a ratio of 1:9-9:1 according to the requirement of a user, so that the effect of relaxing bowel or losing weight is achieved.

Description

technical field [0001] The invention relates to a preparation method of a health food, in particular to a preparation method of a combined banana powder product with functions of laxative and laxative or weight loss. Background technique [0002] At present, the ripeness of bananas on the market is divided into the following seven stages according to the color of the skin: 1. Dark green skin; 6. The epidermis is all yellow; 7. The epidermis is all yellow, and there are spots on the skin. [0003] Banana is a fruit with a respiratory climacteric period. Before the peak respiratory period, the fruit is in a hard green state, which is easy to store and transport; after the peak respiratory period, the bananas will turn yellow and become soft, which is difficult to store and transport. Moreover, the post-harvest loss of bananas is serious, and the problem of unsalable bananas during the harvest period has become increasingly prominent. Therefore, deep processing of bananas is ...

AI Technical Summary

Problems solved by technology

Although the product obtained by the freeze-drying process retains the natural color, fragrance and active ingredients of bananas to the greatest extent, the thickness of the material is required to be very thin. Therefore, the production efficiency of the freeze-drying process is low, the production cost is high, and the one-time investment is large.

The hot air drying equipment is simple and easy to operate, but the production cycle is long, it is difficult to protect easily oxidized and heat-sensitive materials and maintain the original flavor and color of bananas

Spray drying protects easily oxidized and heat-sensitive materials to a certain extent and maintains the original flavor and color of bananas, and the process is continuous and the production efficiency is high, but the one-time investment of equipment is large and energy consumption is high

Microwave vacuum drying has the advantages of short drying cycle, high efficiency, good product quality, sterilization, and low processing cost. At the same time, it also has problems such as difficulty in continuous production, great impact on workers' health during production operations, and high one-time input costs.
