Popis: The manner in which sodium metabisulphite is taken up by potato tissue from boiling aqueous solution has been investigated in respect of depth of penetration, extent of uptake and scalding time: uptake relationships. The extent to which 45Ca and 35S migrate to the centre of potato strips during hot-air drying after scalding in solutions of 45CaCl2 and NaH35SO3 has been examined autoradiographically. 45Ca is more uniformly distributed than 35S which shows a greater tendency to concentrate at the strip centres. Losses in measurable SO2 during hot-air dehydration are predominantly chemical rather than physical.
