Problems solved by technology

[0004] The above technologies all use rehmannia glutinosa as raw material to produce stachyose products, but there are the following technical defects: 1) the purity of stachyose is not high, and the yield is low; 2) the process is complicated, the operation cost is high, and it is not suitable for industrial production; 3) The complexity of processing aids reduces the controllability of product risks: for example, the use of macroporous adsorption resins will increase the possibility of introducing heavy metal ions into the final product

Abstract

The invention relates to an industrial production method for extracting stachyose from radix rehmanniae. The method comprises the following steps: (1) carrying out juice extraction; (2) carrying out impurity removal; (3) carrying out decoloring; (4) carrying out ion exchange; (5) carrying out vacuum concentration; and (6) carrying out sterilizing and spray drying, thereby obtaining a powdery stachyose product, of which the stachyose purity is higher than 70%.

Description

technical field [0001] The invention relates to a production method of stachyose, in particular to an industrial production method for extracting stachyose from rehmannia glutinosa. Background technique [0002] Stachyose is a functional oligosaccharide that naturally exists in the Lamiaceae stachyus plant and can significantly promote the proliferation of beneficial bacteria in the human intestinal tract. It is known as "natural super strong bifidus factor". Stachyose has a clear structure, molecular formula C 24 h 42 o 21 , molecular weight 666.59, it is composed of fructose, glucose, galactose, and galactose polymerization, and the effective usage amount is 0.5-3 grams per day. At present, stachyose in the market is obtained by extracting and separating the traditional Chinese vegetable caddis worm as raw material. Compared with products such as isomalto-oligosaccharide and fructo-oligosaccharide (effective use amount 8-15 g / day) obtained through enzyme engineering tra...
