1. dl-alanine is finished all in thousand grade purification workshop; this could insure the health and microbiological indicators as requirements. total colony count of the product is less than 200 / g, far less than 1000 / g of general standard.
2. because the total colony is very few,the product inventory period is extending,completely solve the product transportation,inventory process discoloration,mildew,odor and other issues.
3. dl-alanine has higher crystallization density reaching to 75~84%, the crystalline particles are uniformly.sinogel company dl-alanine has high fluidity, it is easy to mix and dissolve when used as food additives.
4. do not add any anti blocking agent.
5. dl-alanine appearance is white,10%solution transmittance greater than 98%,generally more than 99%.each batch of products to increase 0.02-micron membrane filtration experiments,to ensure that no visible impurities.
