Abstract

The invention discloses a preparation method of high-purity stachyose. The method comprises the following steps of S1, cleaning and baking raw materials to obtain dried raw materials; S2, performing water extraction and juicing on the raw materials, and performing filtering to obtain a sugar solution; S3, adding yeast into the sugar solution, and carrying out constant-temperature static culture to obtain a fermentation solution; S4, adding a clarifying agent calcium hydroxide into the fermentation solution, and taking a supernate; S5, adding activated carbon into the supernate, and taking a filtrate; S6, introducing the filtrate into a nanofiltration membrane for purification to obtain a purified solution; S7, introducing ion exchange resin into the purified solution to obtain a stachyose solution; and S8, concentrating and drying the stachyose solution to obtain the stachyose. The method is simple in step, wide in material source, convenient to operate, complete in technology and easy to control in process, facilitates large-scale industrial production and creates relatively high social benefits. Experimental results show that the prepared stachyose is high in purity and has obvious competitive advantages compared with similar products.

Description

technical field [0001] The invention relates to the technical field related to sugar production, in particular to a method for preparing high-purity stachyose. Background technique [0002] Stachyose is a naturally occurring tetrasaccharide, a functional oligosaccharide that can significantly promote the proliferation of beneficial bacteria such as Bifidobacteria. The pure product is a white powder with a slightly sweet taste and a sweetness of 22% of that of sucrose. It has a pure taste without any bad taste or peculiar smell. Its molecular structure: "galactose-galactose-glucose-fructose". It can promote the formation of beneficial bacteria in the digestive tract as dominant bacteria, inhibit the production of spoilage bacteria such as Clostridium aerogenes, and produce a large number of physiologically active substances, adjust the pH value of the intestinal tract, kill pathogenic bacteria, and prevent spoilage Product generation, inhibit the production and absorption o...
