Vitamin Potency

Vitamin A deficiencies in the diets of albino rats have been overcome by feeding commercial pilchard oil. The effects of graduated doses have been examined and satisfactory growth rates have been obtained by feeding 12 mg. per day per rat, though no emphasis is placed upon absolute evaluation of vitamin potency. In comparison colorimetric assay gave values lower than the feeding experiments indicate.

The vitamin A content of liver oils of five species of salmon in the genus Oncorhynchus has been determined. The richest samples contained 40 times, and the poorest twice as much vitamin A per gram as a sample of cod liver oil stated to contain 500 A.D.M.A. units per gram. Potencies of samples were in descending order: Skeena spring, Vancouver spring and sockeye, coho, pink and chum salmon. Oil content of the livers averaged 5 per cent and percentage of liver in the fish 2 per cent. The melting point, unsaponifiable matter and iodine value of the oils have been determined.

The total oil in samples of canned British Columbia sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon, each from three different localities, contained respectively 50, 67, 67 and 50, 67, 67 international units of vitamin D per gram, equivalent to average contents of 1700 and 880 international units in the oil per pound of contents for the sockeye and pink samples respectively. The oil in the cans of sockeye salmon from two of the localities contained approximately 2.5 and 2.0 A.D.M.A. units of vitamin A per gram respectively. A composite sample of the oil in all the cans of pink salmon contained no appreciable amount of vitamin A. Several physical and chemical characteristics of the oil samples are given.

Vitamin A deficiency (VAD) is a public health problem in Ghana. Research on the orange flesh sweet potato root has been given prominence because of its high β - carotene content as a means to enhance the nutritive value and vitamin A content of the traditional diets of Ghanaian children as a long -term intervention towards combating VAD. Two Ghanaian cereal -legume weaning foods: roasted maize- soy blend and fermented maize -soy blend were added to Orange Flesh Sweet potato (O FS) flour from the variety, Beauregard, to develop four weaning food formulations . To each product formulation preparation, 25% and 50% OFS flour was added to the basic cereal - legume meals , and mixed thoroughly. The four weaning formulations were evaluated for chemical composition, sensory characteristics and consumer acceptability. All samples had a range of protein (12.1% - 15%), fat (4.8% - 6.4%), carbohydrate (71.1% – 75.1%), energy (380 - 390 kcal/100g) and minerals (calcium, iron and phosphorus) to ensure good nutrient density, while the moisture content was low (5.3% - 6.1%) for storage stability. The contribution of β -carotene ( 55.18 –115.55 ug/g) by the OFS in the formulations further enhanced the nutritive value of all the blends and is enough to meet the daily β -carotene needs of the children ( 1-6 yrs of 400 -450ug/100g). A higher level of β -carotene was seen in the roasted maize meal weaning foods which make s them a better potential blend for combating VAD. Also, sensory evaluation of the products indicated the highest consumer acceptability score (87%) for the roasted maize meal porridge formulation containing 25% OFS . It is, therefore , concluded that OFS flour has the potential to be used at 25% replacement level in the soy- fortified roasted maize meal formulation, and OFS is a useful ingredient with the potential to improve the β -carotene or vitamin A content of such formulations . This will help alleviate vitamin A deficiency of children in Ghana and other countries with similar problems . It is , therefore, recommended that the orange flesh sweet potato flour be used by mothers as an entry point for enhancing the traditional weaning food preparations .

Separate proximate analyses of the flesh and skin of three freshly-caught ling cod (Ophiodon elongatus) from the east coast of Vancouver island are reported. Average percentages of protein in the flesh and skin were 18.1 and 26.9 (moist) or 87.0 and 88.5 (dry); ash, 1.2 and 2.5 (moist); fat, negligible; Calories per 100 g. (moist), 81 and 117.

Composite Samples

Samples of canned coho (blueback) salmon (Oncorhynchiis kisutch), from fish caught each month of the fishing season (May-September) in a limited area on the coast of British Columbia, were subjected to analysis from which nutritive values were determined by the calculation of calorific values. The average percentages of constituents in composite samples of the entire contents were: water, 72.8; fat, 4.50; protein, 19.9; sodium chloride-free ash, 1.37; sodium chloride, 1.13; calorific value per pound of contents, 562. Percentages of fat, protein, sodium chloride-free minerals, and consequently the food value, reached a maximum in cans containing fish caught in mid-July.
