Tempeh is an Indonesian traditional food that is very fond by whole society, both from those in urban and rural areas. Fresh tempeh, which is made of fermented soybean by Rhizopus, is normally sold as it is. In this form, its shelf life is only 2 days old when stored in room temperature. Tempeh milk and tempeh flour are two of alternatives processing of tempeh. The aim of this research is to determine the influence of temperature for protein solubility in tempeh flour and tempeh milk preparation. Beside taste and aroma, several nutritional value, such as fat, carbohydrate, coarse fiber, isoflavon were also determined toward the optimized temperature tempeh milk and tempeh flour. The protein content was determined by Kjeldahl method, the carbohydrate content was analyzed by Luff Schoorl method, isoflavon content measured by HPLC, coarse fiber was determined gravimetrically and taste and aroma was determined organoleptically. Tempeh milk was prepared in the range of temperature of 60 to 90oC. Tempeh flour was made by drying the side product of tempeh milk by using dehydrator apparatus. Then tempeh milk was pasteurized to increase the shelf lifes. The results showed that the optimum protein solubility was obtained with the value of 0,33% (w/v) at 70oC. Organoleptic test showed that tempeh milk with 7% (w/w) and 8% (w/w) sugar content had taste score of 1,87<?<2,82 and 2,81<?<3,49 respectively, on the other hand comercial soy milk had taste score 3,79<?<5,00. Milk containing 0,25% (v/v) and 0,5% (v/v) vanilla had the aroma score of 1,92<?<2,76 and 3,12<?<3,88 respectively, while for commercial soy milk the taste score was 3,38<?<4,81. Soluble protein in tempeh milk remained stable after storage for one week at 4oC. Tempeh flour with the particle size of 40 mesh, contained of 3,48% (w/w) fat, 38,33% (w/w) protein and 9,71% (w/w) coarse fiber.
