Preparation of Soymilk Using Different Methods

Abstract

The present experiment was conducted to prepare soymilk from whole soya seed by using various techniques. Twelve (12) soymilk samples were prepared by three different methods with four concentration level. Each sample was analyzed for proximate composition and sensory qualities were evaluated by a taste panel. No significant difference was found between dehulled soy seed blending milk and whole soy seed powder milk. But 125g concentration obtained highest score from the judges. From the results of chemical analysis, significant difference was found in terms of moisture, total solids, solids- not- fat, protein, fat, carbohydrate, ash content and acidity percentage. Dehulled soy seed blending milk contained more moisture, protein, fat and ash content. On the other hand, a sharp increase of nutrient concentration was observed with the increase of soymilk concentration. But soymilk of 150 and 175g concentration become thicker after boiling which had fewer acceptances by the judges. Considering the physical and chemical properties of all samples, it is recommended that 125g concentrate dehulled soy seed blending milk may be prepared in industrial scale.
