Biological calcium carbonate(oyster shell powder)
Appearance:White or almost white powder
CAS No.:471-34-1
Molecular Formula:CaCO3
Molecular Weight:100.09
Usage:As a nutritional supplement, the natural source is safer, more suitable for human digestion and absorption, and is one of the best nutrient calcium sources. Biological calcium carbonate has a high calcium content. Its calcium content is 3 times that of calcium lactate and 4 times that of calcium gluconate. The three indicators of good nutrition, absorption rate, utilization rate and animal weight gain are better than calcium in milk. Moreover, it has no peculiar smell and small side effects; it can be widely used in food, medicine and other industries. In addition to being a nutritional enhancer, it can also be used as an alkaline agent, dough regulator or anti-caking agent.
Packaging and Storage:25kg, inner packaging is food grade PE bag, outer packaging is composite paper bag, or customized packaging according to user requirements.
Storage conditions: Store in a dry, clean, cool and ventilated placeShelf Life: In conform to the specified storage conditions and packaging is complete, shelf life is 2 years.
