Strawberry pulp was separated into serum and Insoluble pulp by centrifugation. The serum was concentrated in vacuo at 55~58$^{circ}C$ and 10% aroma recovered. Two folds concentrated strawberry pulp was prepared by mixing concentrated serum, aroma fraction and Insoluble pulp. To develop aroma-rich jam, the strawberry jam was prepared by filling mixture of concentrated pulp, sucrose, citric acid and pectin into retortable pouches and by heating them after heat-seating. The color and flavor quality of the jam prepared by new method were better than the jam prepared by conventional method, as Indicated by GC, GC/MS data, surface color and anthocyanin contents. These results were confirmed by the sensory evaluations. Flavor off-flavor, color intensity and overall acceptance were superior to the conventional method.
