Example Embodiment

[0019] Example 1

[0020] A kind of rice preparation MSG process steps are as follows:

[0021] (1) Wash the rice once, drain off the rice water, add water to soak, the water level should be 25 cm higher than the rice layer during the soaking process, soak for 2 hours, add the soaked rice and soaked rice water to the mill to refine the fineness More than 60 meshes, and adjust the rice milk concentration to 17 Baume;

[0022] (2) Adjust pH 67 with calcium chloride, add medium temperature alpha amylase according to 0.5% of the weight of rice, heat the rice milk to 50°C and keep it for 80 minutes;

[0023] (3) Add 0.3% trypsin by weight of rice to the rice milk, keep it at 50°C, the enzymolysis time is 7 hours, and heat the rice milk to 85°C for 15 minutes;

[0024] (4) The rice milk is filtered in a plate and frame, and the rice residue is filtered into feed. The filtrate is added with glucoamylase at 0.15% of the weight of the rice, and the temperature is controlled at 64°C for 17 hours...

Example Embodiment

[0026] Example 2

[0027] The experiment was carried out with the same process parameters as in Example 1, except that step (2) adjusted pH 6.8 with calcium chloride, and added medium-temperature α-amylase at 0.6% of the weight of the rice, heated the rice milk to 55°C and kept it at 90 Step (3) Add 0.4% trypsin by weight of rice to the rice milk, keep it at 55°C, the enzymolysis time is 8 hours, and heat the rice milk to 85°C for 15 minutes.

Example Embodiment

[0028] Example 3

[0029] The experiment was carried out with the same process parameters as in Example 1, except that step (2) adjusted pH 6.6 with calcium chloride, and added medium temperature alpha amylase at 0.4% of the weight of the rice, and heated the rice milk to 45°C and kept it at 60°C. Step (3) Add 0.2% trypsin by weight of rice to the rice milk, keep 45°C, enzymolysis time is 6 hours, and heat the rice milk to 85°C for 15 minutes.

Abstract

The invention provides a process for preparing monosodium glutamate from rice so that the cost of raw materials is saved. According to the process, by virtue of technological innovation, the fermentation liquor raw material proportion is properly adjusted, and the sugar refining process is adjusted; compared with an original process, the process has the advantages of reasonably utilizing resources, increasing the process technical index and saving the cost of the raw materials.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a production process for preparing monosodium glutamate from rice. Background technique [0002] Rice in the southern region is the most important raw material for starch. Southern enterprises in the monosodium glutamate manufacturing industry can save production costs by using rice to prepare reducing sugar. The current process uses a double-enzyme method to prepare reducing sugar. The development of this process has gone through decades. In this process, rice waste residue from sugar production is mostly processed into low-value-added feed, and the protein in rice is not fully utilized. Protein in rice waste residue is the most important component, accounting for more than 80%, and it is the best nitrogen for glutamic acid fermentation. source. Contents of the invention [0003] In order to make full use of the protein in rice, a process for preparing monosodium glu...
