Leftover meals, have been used to make feed for domestic animals. This report describes fried garbage manufacturing with fat under reduced pressure and repeated runs. The level of saturated and mono-unsaturated fatty acid increased with usage, while polyunsaturated fatty acid level decreased. As for fatty acids of fried meal fat, this was not observed but under storage at 37°C, it was. The determination of chemical components, mineral and PCB of raw or fried garbage was conducted. A comparison with other data, indicated fried ones have as high qualities as the other guaranteed feeds for animals.
Two meals were made for sea bream aquaculture. One was made of soluble fish, fish meal, dried Tofu cake (bean curd lees), wheat meal, crab-processing waste, corn meal and fish oil. The other one was made from dried garbage, crab shells, wheat meal, corn meal and crab-processing waste. These meals were examined for preservation with or without antioxidant. Preservative conditions were day-light irradiation, fixed 40°C (dark), cold-storage (-20°C, dark) for 20, 40, and 60 d. Acid, peroxide and fatty acid profile and carotenoidal coloring matters were determined. Under conditions of day-light irradiation or of a temperature of 40°C, feed containing garbage without antioxidant showed inferior fat quality (POV; 26.1 79. 7, 26. 1→ 42.3), but with antioxidant, improvement was noted (POV : 26. 1→ 30.1).
