フィッシュミール製造におけるエネルギー投入量の推定

Abstract

The input of energy and non-energy goods in the manufacture of fish meal was examined. The amount of these goods was then converted into energy input. The estimated energy input for fish meal manufacture was 1, 600-2, 300 kcal per kilogram of product. Since this value is one half or one third of that for the production of starch or its related products, it can be said that fish meal plant is less energy intensive than other food processing plants. The total energy input, which is the sum of energy input in catching process and that in manufacturing process, was also estimated to be 4, 000-17, 000 kcal per kilogram of product. This result indicates that the fish meal made of sardine captured near Japan is more energy intensive than the maize which is transported for a long distance from USA as a principal constituent of assorted feed.
