Abstract
Strained lees of soy-sauce made from whole soy-beans was desalted and dried for recycling as livestock feed stuff. Formulation of the feed using the finished product is flexible as 98% of the salt in the raw lees has been removed by desalting. The product can be used as a source of nitrogen in the feed formula. 581kcal/100g of energy especially composed of crude fat is included in the product which can also be effectively used for fattening. The product is microbiologically safe as microorganisms were not found in the product and water activity was under 0.3. The suitability of the dry desalted lees of soy-sauce from whole soy-beans for livestock feed was suggested by investigating quality in this study.
