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.

Proximate Analyses

Proximate analyses of samples of canned pilchard from fish caught early and late in the season in one vicinity on the west coast of Vancouver island are tabulated. The average calorific value per pound of content was 747 and 1074 Calories, respectively. The percentage of fat (18.5) in the late-caught fish was almost twice as great as that in the early-caught fish. Separate proximate analyses of the flesh, skin, and bone disclosed significant changes in the percentages of fat, protein, and minerals in these components between the beginning and end of the season.

The proximate compositions and calculated calorific values of individual and composite samples of canned sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon from fish caught in several localities on the British Columbia coast are compared. The resulting data are also presented in such a way as to allow comparison of the composition and energy content of the various constituents in the can, some of which are frequently discarded in the utilization of canned salmon. The average percentages of the total oil, protein, salt (sodium chloride)-free minerals, and Calories contributed by the different constituents in the samples were respectively: flesh—(sockeye) 62, (pink) 72; 85, 81; 55, 54; 73, 78; skin—(sockeye) 11.2, (pink) 15.3; 3.6, 4.3; 9.8, 6.7; 7.7, 9.0; free aqueous liquor—(sockeye) 0, (pink) 0; 11, 14; 5, 7; 4, 8; free oil—(oil) 26, 10; (Calories) 15, 4; bone—(salt-free minerals) 30.2, 32.6. Corresponding average percentage compositions of composite samples of entire contents were: water—(sockeye) 68.6, (pink) 71.5; oil—8.82, 6.75; protein—20.2, 19.3; salt-free minerals—1.57, 1.57. The average energy contents were (sockeye) 749, (pink) 644 Calories per pound. Comparison with published analyses of canned sockeye and pink salmon from Alaska and Washington indicated that more extensive and detailed sampling will be necessary before conclusions can be drawn regarding the comparative compositions and food values of canned British Columbia salmons, and the relation of these values to those of salmon caught to the north and south.

Ashes of composite samples of canned sockeye, pink and blueback salmon and canned pilchard were analyzed for Ca, Mg, Na, Ka P. Cl, S and traces of Cu and Mn. Comparison of the relative amounts of these elements with their concentration in sea water indicates selective absorption of Ca and K over Mg and Na respectively. The presence of Cu and Mn in trades is important for dietetic purposes.

The Individual

Analysis by standard methods of samples of Clupea pallasii from different seasons and localities in British Columbia showed the following ranges in composition: water, 64.2 to 80.2%; oil, 4.1 to 19.4%; protein, 10.1 to 16.8%; ash, 1.9 to 2.8%. Oil content is highest in summer, declines during the fall and winter, and falls to a minimum after spawning time in early spring. There is an accompanying decline in the weight of the fish. Herring are highly variable in calorific value (2.41 to 0.94 Calories per gram). Potential oil yields on reduction as high as 30 gallons per ton are indicated with a minimum of 7 gallons per ton. Average condition factors for samples were determined by averaging the individual condition factors obtained from [Formula: see text], when C is the condition factor, W is weight in grams, L is length in millimetres, and 3.26 is the exponent in the empirically fitted equation W = CLn. This condition factor was found to be positively correlated with oil content and to follow in general the same seasonal trend.

Proximate analyses were made at bi-monthly intervals during 1933–34 on samples of Ostrea lurida, O. virginica, and O. gigas grown under identical conditions in the strait of Georgia. The proportions of glycogen and protein are shown to be approximately reciprocal and the greatest variation to occur during the summer. The energy content varies slightly, attaining a maximum in late fall and early winter, O. gigas having the highest and O. lurida the lowest values.

Objective: Major objective of this study is to determine the calorific value and antioxidant activity of Canavaliarosea. Methods: Petroleum ether extract of the seeds were tested qualitatively for twelve components. Calorific value in kJ/100g seed flour was determined based on the results of the proximate analysis. Enzymatic and non-enzymatic antioxidants were analyzed by standard procedures using UV-Visible Spectrophotometer. Results: C. roseais a perennial creeper with roughly circular compound leaves. Flowers are brightly pink-purple, in racemes. It is having large fruits up to 8-12 cm, with brown dormant seeds inside. Seeds were collected from banks of ‘Kabani’ River (Panamaram) and from various tribal hamlets in Wayanad district, Kerela. Preliminary phytochemical screening reveals the presence of eight compounds such as, tannins,saponins, flavonoids, cardiac glycosides, terpenoids, phenols, coumarins and phlobatannins. The analysis of nutritive value of seed has a higher value of crude protein (48.71 %) and crude carbohydrate (34.07). The calorific value of seed material was 1529.9kJ/100g seed flour. Enzymatic antioxidants superoxide dismutase (38.134 u/mg fw) and catalase (19.051 u/mg dw) then non-enzymatic antioxidants poly phenols (12.81 u/mg dw) and ascorbic acid (10.301 u/mg fw) were tested. All those tests show significant levels of antioxidants in the sample. Conclusion: Hence, the present study providing details about the place of collection, ethnobotanical information, energy content and antioxidant activity of Canavaliarosea.

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.
