Production and sensory characteristics of flavoured soymilk samples

Abstract

The sensory quality characteristics of four flavoured soymilk samples including vanilla, banana, coffee and chocolate were evaluated at varying concentrations of the flavour. This was done to establish the most acceptable flavour and desired concentration for commercial production of soymilk and also to facilitate increased consumption of soymilk for improved nutrition. Hot extraction of the milk from blanched soybeans was achieved by blending in hot water and sieving through muslin cloth. Different concentration levels of the flavours being assessed, namely chocolate, coffee, vanilla and banana, were added. Consumer preference for the various samples was assessed using a nine-point hedonic scale. Addition of flavours was found to improve the sensory characteristics and consumer preference of soymilk. Colour, taste, aroma, mouthfeel and hence overall acceptability of the soymilk samples were improved significantly by the addition of vanilla, banana, coffee and chocolate flavours. The maximum concentrations of the individual flavours for optimal sensory impact were established. Based on the results, the following flavour concentrations are recommended per 100 ml of soymilk: 0.03% vanilla, 0.01% banana, 1.5% coffee and 4% chocolate. © 2003 Blackwell Publishing Ltd.
