Physicochemical properties differ with the composition of fibres.
The utilisation of specific fibres in food products is largely determined by their functionalities, processing conditions, colour and flavor (Tosh & Yada, 2010).
For example, the water-retention capacity of cotyledon fibre is higher than hull fibres because of cotyledon’s capacity to bind more water.
However, the oil-binding capacity of cotyledon fibre is similar to that of hull fibres (Pfoertner and Fischer, 2001 and Guillon and Champ, 2002).
Similarly, colour and flavor display variation in different composition of fibres. For instance, pea cotyledon fibres are white in colour with a neutral beany flavor and its hull fibre is creamy white with a neutral flavor. Both hull and cotyledon fibres made from peas are commercially available for food applications in certain cereal and meat products (Goff et al., 2001 and Weightman et al., 1994), but there remains a great deal of untapped potential in the form of soybean hulls.
