First studies in whey content for incorporated by soymilk content and whey content ratio at 100:0, 95:5, 90:10 and 85:15 and then studied the condition for production, heat treatment at 100 deg C for 10, 15 and 20 minutes and incubating time at 43 deg C for 11 and 22 hours. The best condition was chosen by lactic acid content, pH and organoleptic test in appearance, texture and flavor of product.
