Methyl Anthranilate Content of Ohio Concord Grapes

Abstract

ABSTRACTConcord grapes grown at five locations in Ohio were collected in 1982 and 1983 for analysis of methyl anthranilate (MA) in free‐run and heat‐extracted juice samples. The MA content of free‐run juice ranged from 0.33–2.05 mg/L in 1982 and 0.14–0.91 mg/L in 1983. The MA content was higher in heat‐extracted juice than in free‐run juice. Heat‐extracted juice contained 0.19–2.60 mg/L of MA in 1982 and 0.22–3.50 mg/L in 1983. In general, the MA content increased with maturity and was highest in grapes grown in the coolest regions.
