OPTIMIZATION OF LIQUID CHROMATOGRAPHIC CONDITIONS TO SEPARATE WATER-SOLUBLE VITAMINS

Water-soluble vitamins.

 B-complex vitamins and vitamin C are water-soluble vitamins that are not stored in the body and must be replaced each day.  These vitamins are easily destroyed or washed out during food storage and preparation.  The B-complex group is found in a variety of foods: cereal grains, meat, poultry, eggs, fish, milk, legumes and fresh vegetables.  Citrus fruits are good sources of vitamin C.  Us...

Absorption of water-soluble vitamins.

The water-soluble vitamins vary widely in chemical structure and properties, so it is not surprising that the characteristics of absorption of individual members of the group also show differences. Water-soluble vitamins are absorbed mainly into the blood, some very freely (e.g. ascorbic acid), others (e.g. thiamine) only in limited amounts. Vitamin Biz has an apparently unique mode of absorpti...

Water Soluble Vitamins for Dairy Cattle

Research on effects of water soluble vitamins when fed to dairy cows and field supplementation of some water soluble vitamins has increased markedly in the past few years. In research studies, biotin supplementation (20 mg/ day) has consistently improved hoof health of cows and often increased milk production. Supplementation of niacin, although common, has little effect on milk production unle...

Liquid chromatography with isotope-dilution mass spectrometry for determination of water-soluble vitamins in foods.

Vitamins are essential for improving and maintaining human health, and the main source of vitamins is the diet. Measurement of the quantities of water-soluble vitamins in common food materials is important to understand the impact of vitamin intake on human health, and also to provide necessary information for regulators to determine adequate intakes. Liquid chromatography (LC) and mass spectro...
