Facilitated diffusion of tetrodotoxin analogs (maculotoxin) across semi-permeable membranes into amylase-rich rice water, with concurrent mucopolysaccharide secretion reducing bioaccumulation.
Critical pretreatment for consuming wild apple snails (Pomacea spp.), preventing potentially fatal neurotoxic poisoning from their algal diet.
