The invention discloses a method for preparing a monopotassium L-aspartate dihydrate by a separation process. The method taking L-aspartic acid and potassium carbonate or potassium hydroxide as raw materials comprises the following steps of: adding the raw materials to a reaction vessel; allowing the blended materials to react in the presence of a solvent-deionized water, and then correcting the pH value; decolorizing, filter-pressing, concentrating and cooling the obtained reaction solution; adding a monopotassium L-aspartate dihydrate crystal as a seed crystal to the reaction solution; inducing the monopotassium L-aspartate in the reaction solution to be crystallized so as to form the monopotassium L-aspartate dihydrate crystal with a stable water content; and adding an organic solvent for soaking the monopotassium L-aspartate dihydrate crystal, then directly filtering out a mother liquid, and finally drying to obtain the monopotassium L-aspartate dihydrate. The monopotassium L-aspartate dihydrate obtained by the method has the advantages of large and uniform crystallization granularity and stable water content (based on each batch of the products), thus meeting the requirements for the dihydrate.

The invention relates to a panD mutant gene, encoded protein, a vector, an engineering bacterium and an application of the encoded protein. Series recombinant escherichia coli, for high-yield production of L-aspartate-[alpha]-decarboxylase (PanD), is obtained by changing codon base of the panD gene through random mutation of error-prone PCR. With the application of gene engineering bacterium for high-yield production of the PanD, the efficient transformation of the L-aspartate is achieved, so that [beta]-alanine can be prepared by virtue of a biological method, wherein PanD enzyme activity of recombinant escherichia coli numbered as 6-85 can reach 250U / L or above and [beta]-Ala yield can reach about 8.5g / L, nearly 4 times and 3 times above that of a parent strain.

The invention relates to a novel chelated calcium, which is composed of 50 parts of L-aspartate trehalose, vitamin C37 and sucralose. The chelate calcium is prepared through solution preparation, filtration, chelation, drying and stirring, sieving and sterilization. An international leading chelation theory is adopted, and the collapse of cavitation and high-frequency high-voltage ultrasonic methods are used to reach the molecular resonance frequency, so as to chelate multiple molecules that are extremely difficult to react. The chelated calcium is formed through operations of the molecule chelating nano-energy conversion device. Each calcium ion together with two amino acids chelated therewith is absorbed by intestine in a wrapped manner, and the absorption rate reaches 95%. The chelate calcium has good taste and can be directly taken without side effects. The production process is reasonable, simple, easy to operate and easy to implement in industrial production.
