Abstract

The invention discloses a technology of producing monosodium glutamate from potato starch. The technology comprises the following steps: adding moderate-temperature alpha-diastase, xylanase, 0.2% beta-glucanase and saccharifying enzyme to obtain enzymatic hydrolysate; configuring fermentation medium, sterilizing the fermentation medium and cooling the fermentation medium to 33 DEG C; selecting and inoculating corynebacterium crenatum B9 in the fermentation medium, wherein the inoculum size is 1%, then fermenting at 38 DEG C and cultivating for 29-31 hours; after fermentation, extracting and refining the extract to prepare the monosodium glutamate. The monosodium glutamate prepared according to the technology has a purity of higher than 99.2% and completely satisfies the national requirements of salt-free monosodium glutamate. According to the technology, the corynebacterium crenatum B9 strain can be directly inoculated to ferment; moreover, the technology is high in fermentation efficiency, short in fermentation time and economical in cost. The salt-free monosodium glutamate of the invention is prepared from potato starch and opens up a new direction in the monosodium glutamate production industry.

Description

technical field [0001] The invention relates to a process for producing monosodium glutamate from potato starch, which belongs to the field of biotechnology monosodium glutamate production. Background technique [0002] Potatoes, scientific name potato. It is an important food and vegetable dual-purpose crop. Potatoes are rich in vitamins and trace elements such as calcium and potassium, and are easy to digest and absorb, rich in nutrients. In European and American countries, especially North America, potatoes have long been the second staple food. Potatoes are beneficial to the recovery of patients with hypertension and nephritis edema. [0003] Potato flour (PotatoFlour) is made from potatoes, including the skins, that have been cooked, dried and finely ground. The production process of potato starch is basically the same as that of fresh sweet potato, but industrial production of potato starch is simpler than manual production. It is mainly organized by the processes ...
