The nutritive value of canned pilchard (Clupea pilchardus Walb.)
Abstract
In the present paper investigations of chemical composition and energy value of adriatic canned pilchard in vegetable oil are reviewed. For this purpose samples from the commercial product were collected in Yugoslav factories during the 1947 and 1948 fishing seasons.
Before having been examined chemically the canned fish was separated mechanically from the oil. The fish-oil weight ratio was calculated and plotted in table I and II. Table IV shows the average of this analysis. After having being separated from the oil the fish was dried with filter paper, weighed and homogenized. In this material the individual compounds were determined by standard methods.
As it is evident from table I and II the amount of water in the individual samples is varying in a wide range, namely between 44,8-58,8%.. The fat contents range between 11,4-20,8% and the protein contents between 25,9-31,4%. It must be pointed out that the amount of salt added to the samples of the 1947 season is to high.
The average energy value per 100 fish was calculated 277 calories in the 1947 and 247 in the1948 season. The average energy value of the whole contents was found to be 431,4 calories per 100 grams.
Similar investigations were carried out on two samples of Portuguese canned pilchards. The difference in regard to fish and free oil contents was found greater as in the Yugoslav samples. On the basis of the results reported by French authors the energy value of Yugoslav sardines seems to be greater then that of French and Portuguese canned pilchards.
A comparison of own results was made with the chemical composition and energy value of Norwegian canned Fish. This products contain more fat and less protein. The energy value of canned sprat (Clupea sprattus) was calculated 340 calories and that of canned herring (Clupea harengus) 327 calories per 100 grams.
