Vitamin B2 Riboflavin Introduction
Vitamin B2 Riboflavin is a dry uniform flowable particle made by microbial fermentation which uses glucose syrup and yeast extract as raw materials and then gets refined through membrane filtration, crystallization, and spray-drying process.
Vitamin B2 Riboflavin Properties
Vitamin B2 Riboflavin is to be added to animal feed in order to maintain body health, accelerate growth and development, and keep the integrity of skin and mucous membranes. The product is a yellow to brown evenly high fluidity particle with a melting point of 275-282 ℃, slightly smelly and bitter, soluble in dilute alkali solution, and insoluble in water and ethanol. DryRiboflavin remains quite stable against oxidants, acid, and heat but not alkali and light which would pose to a fast decomposition of it, particularly in alkaline solutions or ultraviolet. Thus it is highly advised that this product must be sealed from light and stay away from alkaline substances in the premix to tackle unnecessary loss, additionally when there is free water around—the more free water, the more loss. However, Riboflavin has good stability if it appears as drying powder in darkness. However, the feed pelleting and bulking process lay a damaging impact on the Riboflavin– about 5% to 15% loss rate by pelleting process and about 0 to 25% by the bulking process.
