Vitamin B12 is destroyed by the addition of substantial amounts of vitamin C in the presence of copper. Effects of carnosine and anserine, natural water-soluble antioxidants, on the destruction of vitamin B12, were studied. Addition of carnosine (l0mM) effectively repressed the destruction of vitamin B12, but anserine had only weak inhibitory effects. 

Effect of Light-Induced Riboflavin Degradation on the Loss of Cobalamin in Milk

To evaluate the loss of biologically active cobalamin in milk during light-induced riboflavin degradation, various milk samples were exposed to fluorescent light (3,500 lx) for 24 h at 4°C. Total

Vitamin B12 among Vegetarians: Status, Assessment and Supplementation

The status of vitamin B12 among vegetarians, the diagnostic markers for the detection of cobalamin deficiency and appropriate sources for sufficient intake are discussed, through the description of the features and functions of Vitamin B12 and its absorption mechanism.

Biologically active vitamin B12 compounds in foods for preventing deficiency among vegetarians and elderly subjects.

To prevent vitamin B 12 deficiency in high-risk populations such as vegetarians and elderly subjects, it is necessary to identify plant-source foods that contain high levels of bioactive vitamin B12 and, in conjunction, to prepare the use of crystallineitamin B12-fortified foods.

TLC SEPARATION AND ANALYSIS OF VITAMIN B12 AND RELATED COMPOUNDS IN FOOD

ABSTRACT To evaluate why differences between the vitamin B12 contents determined by both microbiological and intrinsic factor-chemi-luminescence B12 assay methods occur in some edible shellfish and
