Development of small soymilk and soya paneer makers

Abstract

Soybean provides a cheaper and protein rich alternative to animal protein. In Bangladesh, utilization of soybean in food items are scarce due to unavailability of suitable processing machines. Soymilk production and pasteurization machines can assist in increasing the human consumption of soybean by making soymilk and soya paneer. Thus, the experiment was conducted during 2019-21 to develop soymilk making machinery to increase consumption of soybean as human foods. Soymilk making machines consisted of a blender and a pasteurizing unit. The holding capacity of the blender and the pasteurizing units were 2 liters and 6 liters per batch, respectively. In the improved model, the operational time of the blender was 15 seconds corresponding to 83.68% blending efficiency to prepare soymilk for each batch. Time for raising the interlayer water temperature up to 100 ºC was 37.67 minutes. The soymilk was prepared within 20 minutes pasteurizing. The soya paneer was prepared and sensory evaluation was done. The panelists showed their satisfactions both on soymilk and soya paneer.
