Vitamin D3 or known as cholecalciferol is a common chemical substance present in certain foods such as eggs, fish, and dairy products. The powders appear as fine colorless crystals and are easily soluble in fat. This substance is very crucial in the regulation of calcium metabolism and bone health. Enough dietary intake can prevent rickets caused by the lack of bone mineralization. In addition, vitamin D3 plays a role in muscle development since the vitamin D receptor is in the muscle tissue and its deficiency can lead to muscle weakling. having enough vitamin D3 dietary intake also prevents colorectal cancer and multiple sclerosis.
The production process of Cholecalciferol consists of several steps. The first step is to prepare the 7- dehydrocholesterol as the raw material. The rection took place in a insulated reaction chamber which consisted of an ultra-violet mercury lamp to irradiate it with 200-240 bm wavelength light for 15 minutes, converting it to vitamin D3. Along the process, the material was stirred continuously to increase the reaction rate. The addition of ethanol to the 7-dehydrocholesterol made the reaction more efficient.
The second step was to transfer the pre-vitamin D into a heating vessel to transform it into vitamin D3. Once the reaction was complete, the mixture was put in a rotary evaporator to remove the unwanted ethanol. The final product would be a cholecalciferol (vitamin D3) which was a colorless powder.
