By the amount of total microorganism 2.5x102 CFU/g, Yeast and Fungus <25 CFU/g, Moisture 4.75% Fat 6.54% Protein 48.06% Ash 7.47% Fiber 0.54% Carbohydrate 32.64%. The study of 3-differrent-temperature of storage were 28, 40 and 50 degree Celsius. In 90-day storage checking; found that all of the three variation had overall liking, the characteristic appearances and color were different, but flavour, taste, and texture were of no difference.
