At present, there are many types of VCs on the market, which are mainly divided into four categories: ordinary VC, coated VC, VC salts and VC ester derivatives. Let's take a look at the performance of various VCs. VC variety ordinary VC envelope VC VC salt VC ester derivatives
Conclusion
A, VC polyphosphate ester is hygroscopic, poor fluidity, low domestic standards, from the process requirements, is a mixture of many derivatives and unreacted products, the products of various manufacturers vary greatly, there is no feed processing residue Rate comparison test, and no bioavailability test data. Other vitamin C phosphate derivatives are currently not used domestically.
B. Strictly speaking, only the envelope VC has sustained release in water, and some VC esters are also available;
C, the stability of the coated product depends entirely on the specific manufacturer's products, and the cost performance is also.
D, bioavailability, because of different synthesis conditions, VC ester composition is different, bioavailability will be different, the relevant manufacturers have relatively few data.
E, the use of manufacturers need to understand: VC coated film products require detailed product stability, the bioavailability of VC esters.
