Preparation method of cereal, fruit and vegetable chewable tablets capable of clearing heat and eliminating dampness

Abstract

The invention discloses a preparation method of cereal, fruit and vegetable chewable tablets capable of clearing heat and eliminating dampness. Compound fruit and vegetable powder prepared from sweetpotatoes, carrots and pumpkins, glabrous greenbrier rhizome and radix puerariae mixed powder and the like are added to cereal powder prepared from raw materials of wheat germs, brown rice, corn and red beans for blending, so that the cereal, fruit and vegetable chewable tablets comprehensive in nutrients are obtained. Compared with an extrusion puffing and cooking technology, a baking and frying technology adopted by the preparation method disclosed by the invention has the characteristics of being low in equipment investment and large in processing quantity, the prepared cereal powder has rich scorch aroma, and is low in water absorption rate, low in viscosity and easy to disperse in water, water molecules are in sufficient contact with other materials, and agglomerating is not liable togenerate; a radio frequency sterilizing technique is utilized, so that the problem of microbial contamination of low-water-activity foods is solved; the cereal, fruit and vegetable chewable tablets prepared by the technology disclosed by the invention have the advantages of being convenient to carry, good in mouth feel, stable in quality, long in product shelf life and the like, nutrient components are easy to absorb, and after being eaten for a long term, the cereal, fruit and vegetable chewable tablets also have the advantages of clearing heat, eliminating dampness and reliving constipation.

Description

Technical field [0001] The invention relates to the technical field of health food processing, in particular to a method for preparing a chewable tablet for clearing heat and removing dampness from cereals, fruits and vegetables. Background technique [0002] Cereals, fruits and vegetables are rich in nutrients and contain a lot of dietary fiber, vitamins, and minerals. They are indispensable nutritional supplements for people. However, there are many kinds of cereals, fruits and vegetables, and they are rich in nutrients. Consumers cook and process them by themselves, which is time-consuming and laborious, and it is difficult to ensure the quality of eating. Therefore, the development of convenient, delicious, chewable tablets rich in a variety of cereals and fruits and vegetables has become a research hotspot for food processing companies and developers. [0003] Cereal grains contain a small amount of anti-nutritional factors, and at the same time contain a large amount of indi...

Problems solved by technology

However, the water absorption capacity of the samples in the extrusion process and the cooking process is relatively large, the starch absorbs water and expands rapidly, and the viscosity increases rapidly, which prevents the chance of water molecules from contacting with other materials and reduces the speed of water penetration.

[0004] At the same time, due to the different nutritional components of the two types of raw materials, grains and fruits and vegetables, satisfactory food quality cannot be achieved through simple mixing of the two; cereals, fruit and vegetable powders are generally made by hot air, freeze-drying, or spray-drying dehydration. The concentration is 0.1-0.9, which is a food with low water activity. Although food-borne pathogenic bacteria cannot grow under low water activity conditions, they can survive for several months to years. Therefore, even a small amount of pollution will be harmful to human health. It poses a great threat, and the traditional thermal sterilization method is not enough to solve the problem of microbial contamination of low water activity foods, and the finished chewable tablets processed from this are also inevitably subject to the threat of microbial contamination
