Tell us about your production challenge

Vitamin C is an essential nutrient, but the human species lost the ability to produce it biologically during the course of evolution. Instead, we source the substance either from whole foods or vitamin C manufacturing. The chemical characteristics of the natural nutrient and processed compound are the same, but supplements offer higher concentrations, especially to persons with nutrient deficiencies.

Sorbitol fermentation achieves nature-identical synthesis of vitamin C

Vegetables and fruits such as kale and lemon are rich sources of vitamin C. But the natural compound is susceptible to light and oxygen, which could dent the extraction yield of processing. Instead, industrial production often relies on crops like corn and wheat for vitamin C manufacturing.

Sorbitol derived from the feedstock undergoes a double cycle of fermentation and filter pressing to synthesize ascorbic acid. The two-step fermentation process recovers around 60% of the product with 95% purity.

Chemically modified disintegrants break up the binders faster

The bioavailability of synthetic vitamin C is identical to that in food-derived vitamins. But the efficacy of supplements also depends on other ingredients besides ascorbic acid.

Disintegrating agents such as cellulose gum or starch facilitate absorption by the body after the dosage is ingested. Meanwhile, advances in this department are developing superdisintegrants that counter the strength of binders to speed up the release of the vitamins.

Add the right lubricants to address sticking issues during production

The flowability of the raw materials presents a significant challenge to vitamin C manufacturing. Apart from risks of caking, lack of flow can result in surface imperfections in the final capsule or tablet. Additives like magnesium stearate or stearic acid act as lubricants to decrease friction between the tablet and the forming die.

Silicon dioxide or other flow agents prevent the formation of lumps as the granules travel along the production line.

Label the packaging quantities in terms of the daily vitamin requirement

As a producer, you must always declare the nutrient reference values (NRV) of vitamin C supplements. International labeling guidelines stipulate that these values should be expressed in metric units or as a percentage of the recommended daily allowance (RDA).

In 2019, the Food and Agriculture Organization set the RDA of vitamin C for adults at 60 milligrams. However, national authorities may establish different quantities. Authorities in the US and EU recommend a daily intake of 80 milligrams for adult females and 90 milligrams for adult males.
