This products is of high stability and permanent effect by applying microcapsule coating technology which overcome the original deficiency of VC in production and application. Its every index up to domestic and foreign advanced level and the products are highly appraised by clients.
Quality Index:
Appearance: white or light yellow microgranule
Content(ascorbic acid C6H8O6): min97%
Dry loss: max2%
Total arsenic(As,mg/kg): max3
Heavy metal(base on Pb,mg/kg): max20
Function and characteristic:
Wide application: prevent animal from VC deficiency and anemia, promote the form of connective tissue, lengthen the period of exuviation, improve immunity and resistance to response and relieve the toxicity of body's metal ion.
Good stability: resistance to high temperature and high pressure, greatly reduce the loss during the feed processing caused by high temperature, humidity, heat and extrusion, avoid the loss of VC and the dissolving in water during storage period.
High availability: dynamic and slowly release in animal body, sustainedly participate in the reaction of organism, show physiological function.
Excellent effect: good fluidity of microgranule,can be used together with other feed not to affect the product's performance, to reduce culture cost and improve culture rate.
Usage and dosage: used to produce premixture and concentrated materials to be added into feed or single to be used.

High biological availability
The experiment of culture of grass carp designed by China Aquaculture Institute showed that the coated VC is higher biological availability than that of ordinary VC.
The different effect on crucian growth when added ordinary VC and coated VC into the feed.
