Here d sorbitol is converted to l ascorbic acid via 2 keto l gulonic acid 2kga as key intermediate using a bio oxidation with gluconobacter oxydans and several chemical steps. Vitamin d is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun.

Field of the invention.

Vitamin d manufacturing process. A vitamin manufacturing plant will typically test the batch at different locations in the mixer to make sure the levels of each vitamin are consistent throughout. This invention relates to a method of manufacturing vitamin d 2 vitamin d 2 activated type vitamin d 2 activated type vitamin d 3 and their derivatives from 7 8 dihydroxy vitamin d 2 7 8 dihydroxy vitamin d 3 and their derivatives. Vitamin d3 is manufactured from cholesterol which is isolated from wool grease.

After the vitamin blend has been mixed in the mixer workers dump it into a hopper above the machine. There has been a remarkable development of study of vitamin d since 1958 when 25 hydroxy vitamin d 3 was. Purified cholesterol is then taken through a four step chemical process to make 7 dehydrocholesterol this is otherwise known as pre vitamin d3 next the pre vitamin d3 is irradiated to produce vitamin d3 cholecalciferol.

Background of the invention. Then some more steps occur in the liver and kidneys to convert vitamin d3 into the form used by our bodies. The cholesterol is converted chemically to 7 dehydrocholesterol which is irradiated with uv light to form pre vitamin.

7 vitamin tablets are made in a tableting machine. Today industrial production processes use additional bio oxidation steps with ketogulonicigenium vulgare as biocatalyst to convert d sorbitol to the intermediate 2kga without chemical steps. It is then that the mixture will go through the encapsulation process to create the vitamin pills.

After pre vitamin d3 is produced it is converted into vitamin d3. This is the same reaction that is used by human skin to manufacture the vitamin from sunlight. 1 25 dihydroxy vitamin d3 this biologically active form is also known calcitriol.

However it is not abundant in food. As more people avoid sun exposure vitamin d supplementation becomes even more necessary to ensure that your body receives an adequate supply. If capsules are not being used the vitamin mixture will be compressed into tablets.

The vitamin powder then flows through the hopper to a filling station beneath and flows from there to a rotating table.
