Optimisation of aqueous extraction of gum from durian (Durio zibethinus) seed: A potential, low cost source of hydrocolloid

► Water to seed (W/S) ratio had the most significant (p < 0.05) effect on the solubility. ► The extraction process at very acidic or alkali pH led to reduce the volume-weighted mean. ► Aqueous extraction variables exhibited the most significant effect on span. ► The aqueous extraction at elevated temperature and alkali pH resulted in the high OHC. ► The durian seed gum with maximum WHC can be used as a potential source of dietary fibre.
