Description
Hydration-mediated toxin leaching through osmotic exchange in freshwater gastropods.
Technical
Facilitated diffusion of tetrodotoxin analogs (maculotoxin) across semi-permeable membranes into amylase-rich rice water, with concurrent mucopolysaccharide secretion reducing bioaccumulation.
Culinary Significance
Critical pretreatment for consuming wild apple snails (Pomacea spp.), preventing potentially fatal neurotoxic poisoning from their algal diet.
Science
Primary Reaction
Osmotic gradient-driven toxin efflux
Parameters
