DSM Nutritional Products has over 60 years experience in the synthesis of
vitamins.
Starting in 1935 with the chemical synthesis of vitamin C, a process invented
by Dr. Tadeusz Reichstein, of the Swiss Institute of Technology in Zurich,
Roche gradually added other synthesized vitamins to its range. Today DSM sells
the full palette of fat-soluble and water-soluble vitamins.
In 1956, Roche began producing carotenoids with the first synthesis of
beta-carotene, and over the years followed up with apocarotenal, apo-ester,
canthaxanthin, astaxanthin, lycopene, zeaxanthin and lutein.
Apart from vitamins and carotenoids, Roche Vitamins moved into other products
of significance to the food, pharmaceutical, feed or cosmetic industries, such
as medicinal feed additives (1970), citric acid (1977), amino acids (1979),
polyunsaturated fatty acids (1988), feed enzymes ( 1990), and cosmetic
ingredients such as sunscreens and emulsifiers (1996).
