Embodiment
[0053] Example: The raw material liquid is the material liquid after VC has been removed by nanofiltration, and the material liquid is yellow. The content of VC glucoside is about 5% and the glucose content is about 20%. The equipment rotation period is 2100s or 35min. The flow rate of the resin = 450 / 35 = 12.8 mL / min, and the feed volume of the reaction solution is about 138 mL. 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 / revolution, the amount of material liquid that can be processed per unit of resin is: 10.8ml material liquid / ml resin; The results of the method for VC glucoside production are as follows:

Abstract
The invention discloses a production method of ascorbyl glucoside, which comprises the following steps: step 1: the ascorbyl glucoside reaction liquid is separated by nanofiltration, and residual VC in the reaction liquid is removed to obtain a nanofiltration concentrated liquid; step 2: the nanofiltration The filtered concentrated liquid is separated by a continuous fluid separation device to remove the glucose in the VC glucoside reaction solution; Step 3: The VC glucoside solution from the continuous fluid separation device is first passed through a positive resin to adjust the pH, and then concentrated through a nanofiltration membrane , remove the inorganic salts in the reaction solution to obtain VC glucoside concentrate; step 4: carry out vacuum distillation and concentration of VC glucoside concentrate, further increase the concentration of VC glucoside, and then crystallize to obtain VC glucoside . The production method of ascorbyl glucoside of the present invention has the advantages of environmental protection, pollution reduction, cost reduction, yield increase, quality improvement and simplified operation.
Description
Technical field [0001] The invention relates to the field of ascorbyl glucoside production, in particular to a method for producing ascorbyl glucoside. Background technique [0002] Vitamin C (VC for short) is one of the essential nutrients for the human body. It is mainly used to treat scorbic acid in clinical practice, so its chemical name is ascorbic acid (Vitamin C, AA). In addition, the unique chemical structure and physiological activity of VC make it widely used in cosmetics, food and medicine as a sour agent, reducing agent, antioxidant, bleaching agent and stabilizer. However, VC also has a series of inherent disadvantages: it is extremely unstable in aqueous solution; it is easily oxidized by oxygen and other oxidants in the air; it will rapidly degrade when exposed to neutral pH, heat, light and heavy metals, which limits it Application in certain fields. Therefore, the development of high value-added VC derivatives has become a hot spot for domestic and foreign scho...
