Abstract
The effect of exogenous pectinase on the levels of 2,5‐dimethyl‐4‐hydroxy‐2__H__‐furan‐one (DMHF) and DMHF‐glucoside was studied in clarified strawberry juice (Fragaria × ananassa, cv. Elsanta). The extent of conversion of DMHF‐malonyl glucoside to DMHF‐glucoside and DMHF was monitored at three different temperatures (45 °C, 50 °C and 60 °C) and at three different pH values (pH 3.0, 4.0 and 5.4). The effect of using two different concentrations of pectinase was also studied. Based on these results, the endogenous levels of DMHF‐malonyl glucoside were calculated for the first time in strawberries. Copyright © 2002 John Wiley & Sons, Ltd.
