A study is made by ion‐exchange and chromatography on silica gel of the organic acids present in apple pulp and peel at various stages of maturity. The concentration of quinic acid falls rapidly throughout the developmental period, whilst that of malic acid reaches a peak at 50–60 days after petal fall. Citric acid, present in much smaller proportion than the other two acids, shows considerable changes in amount and concentration.
