The invention relates to the field of
vitamin production, and particularly relates to a
vitamin D3 beadlet which is long in
expiration date and can be dispersed in cold water. The
vitamin D3 beadlet comprises vitamin D3 oil, 2,6-ditertiary butyl-4-
cresol,
starch sodiilm octenylsuccinate,
maltodextrin and pure water. A production method of the vitamin D3 beadlet comprises the following steps: firstly weighing, then dissolving the vitamin D3 oil, charging
ethoxyquin; and adding the pure water in an emulsifying pot, charging the
starch sodiilm octenylsuccinate, charging white
sugar, waiting for emulsifying; adding a mixture in an oil dissolving kettle in the emulsifying pot, starting a
fluidized bed system and a
starch system for
processing, and pumping the vitamin D3 beadlet out. The
expiration date of the vitamin D3 beadlet produced by adopting the formula can reach 24 months, thus the service life of the vitamin D3 beadlet is prolonged, and the vitamin D3 beadlet can be dispersed in cold water, thus the use limit to the vitamin D3 beadlet can be reduced, and the use range is enlarged; meanwhile, compared with an existing
standard formula, the formula and the production method have the advantages that the production cost can be greatly lowered, and the production benefit of enterprises is increased.
