Yield of durian powder from Mon-Thong durian ranges from 7-11 percent based on the weight of durian fruit. The variable which affects the yield of durian flour is ripeness of durian flesh. The production of durian powder for one batch is approximately 27-30 kilograms and takes 2 days. Time consumed in various steps of the production are as follows: the preparation step before drying needs 5-6 working hours by 10 workers, the drying time of sliced durian flesh in hot-air oven is 20 hours with an electrical consumption of 0.5 kilowatt per hour, the grinding of approximately 27-30 kg consumes approximately 1 hour and 1 worker. Durian powder is obtained by grinding with hammer mill through the sieve with an opening aperture of 1 mm diameter. The chemical properties e.g. moisture, fat, protein, carbohydrate, ash, crude fibre, starch and total sugar content of durian powder were determined. The physical properties e.g. color and viscosity of durian powder were also determined. 100 grams durian powder provides approximately 370 kilocalories with total dietary fibre 11.8 grams, which composed of soluble dietary fibre 3.4 grams and insoluble dietary fibre 8.4 grams. From the content of dietary fibre, durian powder can be classified as high dietary fibre food. Ripeness of durian flesh affected directly to the viscosity of durian powder. The longer period after cutting unripe durian fruit, the more decreasing in viscosity of durian powder. It is recommended that durian powder must be made from unripe durian fruits after cutting of not more than 2 days. The production cost of durian powder is 185.56 baht/kg, when the price of durian fruit is 15 baht/kg.
