Abstract

The invention discloses a chewable tablet rich in green tea dietary fibers and a preparation method thereof, and belongs to the technical field of food processing. The chewable tablet is prepared fromthe following raw materials by the mass percentage: 10%-20% of microcrystalline cellulose, 0.5%-2.5% of citric acid, 10%-30% of xylitol, 0.5%-1% of magnesium stearate, and the balance a compound of green tea dietary fiber powder and maltodextrin. The mass ratio of the green tea dietary fiber powder to maltodextrin in the compound is 1:1 to 1:3. The preparation method adopts a secondary extrusionmodification technology for the green tea dietary fibers extracted from tea leaves, green tea residues are modified by high temperature and high pressure produced during extrusion and shearing of an extruder, and the extruded modified green tea dietary fibers are obtained. The green tea dietary fibers after extrusion modification treatment have good physical properties; compared with green tea residues which are not extruded and modified, the green tea dietary fibers have the water solubility increased from 12.5% to 15.3%, the expansibility increased from 5.6 g / g to 6.8 g / g, and the content ofthe soluble dietary fibers increased from 1.1% to 6.8%.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a chewable tablet rich in green tea dietary fiber and a preparation method thereof. Background technique [0002] my country's tea production ranks first in the world, and a large amount of tea dregs will be produced during tea processing. Studies have shown that dietary fiber in tea dregs is as high as 60-80%. Dietary fiber is divided into soluble and insoluble dietary fibers. The speed of human digestion and the acceleration of cholesterol excretion can also help diabetics reduce the concentration of total cholesterol and triglycerides. It has physiological activities such as preventing diabetes, cardiovascular disease, and lowering cholesterol. Although insoluble dietary fiber cannot be decomposed and utilized by the human body, it is Water swelling promotes intestinal peristalsis, can prevent constipation and prevent colon cancer, and plays an important role...
