The contribution of some B-vitamins in citrus juices is frequently overlooked. Orange juice contains appreciable amounts of thiamine and folacin. Riboflavin, niacin, vitamin B6 and pantothenic acid are also present in sufficient amounts to supply dietary requirements in proportion to the caloric values of the products. Surveys were made on the B-vitamin content in frozen concentrated orange juice (FCOJ), pasteurized orange juice (POJ) and canned grapefruit juice (CGJ) produced in Florida. In each survey, samples collected from various commercial manufacturing plants or from supermarkets were analyzed for all B-vitamins. With the exception of thiamine, all B-vitamins were assayed using the standard microbiological procedures. Thiamine was determined by the thiochrome fluorescence method. In reconstituted FCOJ, thiamine and folic acid appeared in amounts that may be considered as significant in diet, supplying more than 10% of the U. S. Recommended Daily Allowance (U.S. RDA) in a 177 ml serving. Niacin, riboflavin, vitamin B6, and pantothenic acid are all occurring in quantities equal to the level of calories supplied for an average dietary intake. The amount of these vitamins supplied by COJ and CGJ are slightly lower than the reconstituted FCOJ. Study on thiamine content in juices of oranges of different cultivars at various stages of maturity revealed that it increases as fruit matures and differs in juices of differents cultivars. |
