Dietary-fiber-enriched kiwi fruit compound beverage and preparation method thereof

Abstract

The invention relates to the field of food processing and making, in particular to a dietary-fiber-enriched kiwi fruit compound beverage and a preparation method thereof. The beverage preparation method comprises the following steps of 1, superfine grinding; 2, brewer's grain treatment; 3, ultrahigh pressure modification. The composite beverage is low in price, the cost is only two thirds that ofa kiwi fruit beverage in the market, fermented brewer's grains are fully utilized, and the utilization way of the brewer's grains and the competitiveness of a factory are increased.

Description

technical field [0001] The invention relates to the field of food processing and production, in particular to a kiwifruit compound beverage rich in dietary fiber and a preparation method thereof. Background technique [0002] Dietary fiber in a broad sense refers to resistant bag starch and other polysaccharide carbohydrates and lignin that are not nitrated and absorbed by the human body, mainly including cellulose, hemicellulose, pectin, and hydrocolloid substances. It is an edible Sexy plant-based ingredients. In my country, due to the improvement of living standards, major changes have taken place in the structure of food. The staple food rice and flour are gradually replaced by polished rice and refined flour. The daily intake of plant dietary fiber shows a downward trend, leading to obesity. , diabetes, coronary heart disease, peptic ulcer and other diseases of civilization and affluence, so many people choose to take most of the dietary fiber from beverages or fruits. ...

In my country, due to the improvement of living standards, major changes have taken place in the structure of food. The staple food rice and flour are gradually replaced by polished rice and refined flour. The daily intake of plant dietary fiber shows a downward trend, leading to obesity. , diabetes, coronary heart disease, peptic ulcer and other diseases of civilization and affluence, so many people choose to take most of the dietary fiber from beverages or fruits. Therefore, the research on the modification technology of dietary fiber is of great significance to the utilization rate and added value of dietary fiber. Currently, the modification of dietary fiber mainly includes chemical method, physical method and enzymatic method, but due to physical The method requires special equipment, the efficiency of chemical method is low, and the price of enzymatic modification is high, so simple and efficient modification methods still need to be explored

[0003] The application number is 201710027797.8, which discloses a preparation method of laxative high-food kiwifruit ultrafine powder and its chewable tablets. The whole fruit of kiwifruit is used as raw material to carry out high-pressure homogenization, supramolecular microencapsulation, emulsification homogeneity, and ultramicronization. It is prepared by crushing, dry modification and other steps. Its technical characteristics are the use of supramolecular microencapsulation, adding γ-cyclodextrin to kiwi fruit pulp, grinding, adding emulsifier, homogenizing, pre-freezing, and vacuum drying. Obtain the dry powder of the capsule, and then put it on a planetary ball mill to grind with agate to obtain microencapsulated superfine powder. The chewable tablet has the advantages of relieving constipation, regulating the intestinal tract, and having low toxic and side effects. However, the nutritional content of the chewable tablet is Substance may lose activity due to multiple grinding treatments
