Recent studies showed a strong correlation
between content of soluble non-cellulosic polysaccharides (S-NCP) and WHC in plant
material and agro-industry co-products collected in Vietnam [15]. This could be due to the
occurrence of more gaps within the cell matrix that can retain excess water in feed
ingredients which are high in S-NCP. Similarly, it has been shown that the S-NCP fraction in
co-products from vegetable food and agro-industries was linearly related to selected
hydration properties, such as swelling and WBC
