Abstract

The invention discloses a monosodium glutamate production technology which comprises the following steps: fermenting glutamic acid; extracting glutamic acid: a glutamic acid fermentation broth is subjected to pasteurization and two-stage ultrafiltration to obtain bacteria paste and a glutamic acid clear solution, the glutamic acid clear solution is subjected to evaporation and concentration, and is separated after continuously isoelectric cooling to obtain crystallized alpha-glutamic acid and a separated mother solution; mixing, heating and keeping warm and separating alpha-glutamic acid and a crystal transformation mother solution to obtain the glutamic acid, preparing a suspension liquid through mixing the glutamic acid and water, controlling the crystal transformation pH value to be 4.0-5.0, rising the temperature, carrying out the crystal transformation to obtain beta-glutamic acid, neutralizing with a sodium carbonate water solution, then performing activated carbon decolorizing, filtering, carrying out decoloration and iron removal on the filtrate through a granular activated carbon column, performing evaporative crystallization and centrifugal separation on the decoloring solution, drying and screening to obtain the finished product. The monosodium glutamate production technology has the advantages that the discharge of waste liquid during the monosodium glutamate production process is reduced, the consumption of chemicals is reduced, the production cost is reduced, the economic benefit is improved, and the resource recycling is facilitated.

Description

technical field [0001] The invention belongs to the field of food technology and relates to a production technology of monosodium glutamate. Background technique [0002] my country has a long history of monosodium glutamate production, and is a big producer and consumer of monosodium glutamate, with an annual output exceeding 2 million tons. The production of monosodium glutamate generally uses corn as raw material and uses fermentation technology, which is a high-tech industry for deep processing of agricultural products. Due to the large demand, the appearance of monosodium glutamate crystals is white and glossy, and the requirements for regular and neat crystal particles are getting higher and higher. How to improve the productivity and quality of monosodium glutamate has become a key issue in the research of monosodium glutamate production technology. [0003] In the glutamic acid fermentation technology, how to increase the acid production rate and the sugar-acid conv...
