PREPARATION AND CHARACTERIZATION OF DRY CAT FOOD FROM FACTORY WASTES FISH MIXING WITH DIFFERENT CEREALS
Abstract
- The aim of this research is to prepare the dry cat food using factory wastes fish and cereals. Pyi-taw-thar and Nga-khaung-pwa were collected as the rejected low grade fish from Ngwe Pin Lae fish factory, Hlaingthayar Township, Yangon Region. The ingredients were dried by using hot air oven. Dry cat food was prepared from fish by mixing with each cereal namely wheat, corn and soybean. The respective conditions were investigated for varying ingredient compositions and steaming time. The nutritive values, pH, water activity, size stability, metabolizable energy and cat feeding of dry cat food with different cereals were also determined. It was observed that the optimum parameters were 3:7 ratio of fish powder and wheat flour with steaming time of 25 min., 1:1 ratio of fish powder and corn flour with steaming time of 25 min. and 2:8 ratio of fish powder and soybean flour with steaming time of 20 min.. The optimum dry cat food (fish and soybean) was also selected based on the comparison of nutritive values of dry cat food (fish and wheat, fish and corn, and fish and soybean). It was found that the dry cat food prepared from fish and soybean had the highest protein content of 41.5 % and metabolizable energy of 3277.5 kcal/kg.
