Abstract
Production of animal feed from food waste by controlled the moisture content were investigated. Simple structural equipment was regularly fed with food wastes from a university cafeteria, junior high school and restaurant in the city. Moisture content was controlled at 40 % w.b. and 20 % w.b. in the term of curing period and feed production period, respectively. Temperature, moisture content and pH were measured. Final material was analyzed nutritional components as swine feed and safety.
During experimental period, pH was low and curing period pH was less than 5. In addition, since moisture content was controlled 20 % w.b. the aromatic and good handling condition materials were generated. Nutritional components were at the same level as commercial formula feed and the many recycling feed. As to safety, heavy metals, aflatoxin, and pathogenic microbe were satisfied the standards. Therefore, it was thought that the availableness as recycling feed was high. To control the moisture content at 20 % w.b. can reduce the cost for drying and avoid the risk of thermal denaturation. However, it was necessary for investigation that retention time, early decomposition and removal for oil and fat, and prevention of deterioration because the peroxide value was high.
