Abstract

The present invention provides a method for stachyose hydrate extraction. Leaf bamboo shoot or Yintiao are cleaned, grinded and soaked, and then are Paste-pasteurized. The plant protein of the leaf bamboo shoot or Yintiao is coagulated. The fruit compound enzyme which is ten thousandth of the weight of the extraction is added into the extraction for degumming. After the degumming, the solution is filtered by 10000D ultrafiltration membrane, and then is bleached and concentrated in vacuum, and is dried into stachyose hydrate powders. The method solves the problem of the use of chemical reagents which generates lead salt residue. The method shortens the processing time. The production rate of the method is more than 90 percent and the purity is of 95 percent. Raw materials utilization in the method is high.

Description

technical field [0001] The invention relates to a method for extracting stachyose, in particular to a method for extracting stachyose from ground bamboo shoots or silver bars. Background technique [0002] At present, the existing technology extracts stachyose from ground bamboo shoots and silver bars, mostly using water extraction and alcohol precipitation or rolling juice, and then adding chemical reagents lead acetate and oxalic acid to remove tannins. The process takes a long time and the residual lead salts are difficult to remove. . The stachyose extraction method of patent No. 00123630.X adopts the addition of chemical reagents lead acetate and oxalic acid, and the process takes a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new process for extracting stachyose in view of the deficiencies in the prior art, which uses biological enzyme preparations to remove tannin and heat to remove protei...
