Embodiment

[0053] Embodiment: The raw material liquid is the material liquid after removing VC by nanofiltration, and the material liquid is yellow, wherein the content of VC glucoside is about 5%, and the content of glucose is about 20%. The rotation period of the equipment is 2100s or 35min. The flow rate of the resin = 450 / 35 = 12.8mL / min, and the feed volume of the reaction liquid is about 138mL. The amount of resin can be characterized by the ratio of resin volume to feed volume, that is, 12.8:138=1:10.8. In the case of 2100S / rev, the amount of feed liquid that can be processed by a unit of resin is: 10.8ml feed liquid / ml resin; Method carries out the result of VC glucoside production as follows:

Abstract

The invention discloses a production method of ascorbyl glucoside. The method comprises the following steps: 1, performing nanofiltration separation on an ascorbyl glucoside reaction solution, and removing residual VC from the reaction solution to obtain a nanofiltered concentrated solution; 2, separating the nanofiltered concentrated solution through a continuous fluid separation device to obtain a VC glucoside reaction solution, and removing glucose from the VC glucoside reaction solution; 3, adjusting the pH value of the VC glucoside reaction solution separated by the continuous fluid separation device through cation resin, concentrating through a nanofiltration membrane, and removing inorganic salts from the reaction solution to obtain a VC glucoside concentrated solution; 4, performing reduced pressure distillation and concentration on the VC glucoside concentrated solution to further increase the concentration of VC glucoside, and crystallizing to obtain VC glucoside. The method disclosed by the invention has the advantages of being environment-friendly, reduced in pollution and cost, increased in yield and quality and simplified in operation.

Description

technical field [0001] The invention relates to the field of ascorbyl glucoside production, in particular to a production method of ascorbyl glucoside. Background technique [0002] Vitamin C (referred to as VC) is one of the essential nutrients for the human body. It is mainly used clinically to treat ascorbic acid disease, so the chemical name is ascorbic acid (Vitamin C, AA). In addition, VC's unique chemical structure and physiological activity make it widely used as sour agent, reducing agent, antioxidant, bleaching agent and stabilizer in the fields of cosmetics, food and medicine. However, VC also has a series of inherent disadvantages: it is extremely unstable in aqueous solution; it is easily oxidized by oxygen in the air and other oxidants; it will degrade rapidly when exposed to neutral pH, heat, light and heavy metals, etc., thus limiting its applications in certain fields. Therefore, the development of VC derivatives with high added value has become a research...
