Problems solved by technology

At present, the method of producing it is "wet method", that is, it is produced by heating glycine and sodium carbonate in an aqueous solution, the yield is low, and the product separation and purification are troublesome, so its wide application is limited

Embodiment Construction

[0006] 1. Take 7.5 grams of glycine and 5.3 grams of sodium carbonate, put them in a mortar and mix thoroughly, then put them in a glass container, add 7.5ml of water to make a paste, make it into a "wet-solid phase", and adjust the heating power to 50W, after heating for 20 minutes, stop heating, take out the reaction product after cooling, and pulverize to obtain bisglycinate sodium carbonate product, and the yield can reach about 80%.

[0007] 2. Take 7.5 grams of glycine and 5.3 grams of sodium carbonate, mix well, add water to make a paste, make it into a "wet-solid phase", then put it in a microwave oven, adjust the heating power to 75W, and heat it for 15 minutes. The product is cooled, and then the product is taken out and pulverized to obtain the sodium bisglycinate carbonate product with a yield of over 98%. If the raw material of the reaction product is very pure, the product can be used directly as a food additive and pharmaceutical industry agent without purificat...

Abstract

A microwave method for synthesizing glycine sodium carbonate as the additive of food and medicine is disclosed, which features the microwave 'Wet-solid phase' method instead of 'Wet synthesis'. Its advantages are short reaction time, and high output rate.

Description

Technical field: [0001] The invention relates to a synthesis method of a novel food additive and sodium glycinate carbonate used in the pharmaceutical industry, and belongs to the production field of food additives and pharmaceutical industrial agents. Background technique: [0002] Traditionally used food puffing agent mostly uses NaHCO 3 or NH 4 HCO 3 , or their complex products, which are widely used because of their low price, but they are not satisfactory because of their low solubility or the production of water after reacting with acidic substances in food, which deteriorates the production conditions. In recent years, a class of sodium glycinate carbonate has been developed abroad to replace NaHCO 3 As a puffing agent and an acid regulator, it not only eliminates the shortcomings of the latter, but also glycine itself is needed by the human body, so it is also a nutritional agent, so it has been used abroad. In China, it is mainly used in the pharmaceutical indus...
