Method for preparing high grade edible fiber using apple slag as raw material and fruit juice enriched with said edible cellulose

Abstract

The method of preparing high grade diet fiber with apple dregs as material includes high speed shearing, mixing and emulsifying, high pressure homogenizing, dewatering, freeze drying and other technological steps. The produced diet fiber is added into apple juice in certain ratio to obtain apple juice with refined diet fiber. The pure physical process obtains pure natural product containing no any chemical. The process has no environmental pollution and the diet fiber is easy to be absorbed by human body. The diet fiber powder may be used as the additive for other fruit juice and food.

Description

technical field [0001] The present invention relates to a method for preparing dietary fiber and beverage or food rich in the product obtained by the method, especially a method for preparing apple pomace into highly refined dietary fiber and fruit juice drink or food rich in dietary fiber obtained by the method food. Background technique [0002] In recent years, my country's apple planting area and production have increased significantly. With the construction of a large number of fruit juice production lines, a large number of pomace has been discarded, seriously polluting the environment. Apple pomace contains a large amount of polysaccharides, lignin, cellulose, hemicellulose, etc., and is a good new resource of dietary fiber. [0003] In the prior art, the methods for preparing dietary fiber from apple pomace mainly include chemical method and fermentation method. Among them, the chemical method will use a large amount of strong acid and strong alkali and organic ext...

AI Technical Summary

Problems solved by technology

Among them, the chemical method will use a large amount of strong acid and strong alkali and organic extraction solvent in the preparation process, which not only increases the production cost, but also causes serious pollution to the environment, and using a large amount of strong acid and strong alkali will destroy the color quality and taste of the obtained product. At the same time, a part of lignin will be destroyed under NaOH environment, which will affect the yield of the reaction process.

Although the fermentation method does not have the above defects, its production process is complex, the process conditions are high, the process is not easy to control, and the production cost is relatively high

Difficult to promote on a large scale
