Abstract

Soybean is used mostly as the main source of protein for feeds by the livestock industry. It is important that soybeans are properly heat-treated before it is fed to animals. The reason for this is that raw soybeans contain an anti-nutritional factor that can severely interfere with the digestion of protein.This study describes the optimization of heat treatment of soybeans by roasting using a soybean roaster prototype. Results showed that anti-nutritional factor, indicated by urease activity, is minimized if a load of 36 kilograms of soybeans is roasted for 25 minutes at 125 ̊C air temperature. This study also includes a discussion of the design of the prototype, which was based on the anthropometric measurements of Filipino farmers. This study concludes that there is an economic advantage associated with the utilization of the soybean roaster for animal feeds, revealing the potential for small scale farmers to engage in the production of soybeans and cooperatively process their harvest for animal production. The cost of the designed/fabricated machine is much lower than the existing machine in the market, and the roasted soybean costs lower than the commercially available soybean meal.
