Pomegranate is a deciduous tree crop cultivated commercially for its fruit and juice in many parts of the world. Minimally processed fruits and vegetables have become one of the fastest-growing sectors of the food industry. Pomegranates have a relatively new minimally processed product comprised of arils packaged in plastic containers. Fruit quality of minimally processed pomegranate arils is largely unknown in the American market as is the quality of imported fruit. These minimally processed products have been reported as having poor quality by schoolchildren panelists participating in sensory analysis. This investigation included physicochemical and color quality assessment of pomegranate whole fresh market fruit and minimally processed arils. Data were collected on the total weight of arils, 100 aril weight, fruit diameter, fruit length, proportions of intact, damaged, and decayed arils in weight and number, total soluble solids (TSS), titratable acidity (TA), total phenolics, and color. There were significant quality differences between minimally processed pomegranate products and between imported versus domestic fruit. Pomegranate fruit imported from Chile did not meet market standards for internal quality in that they had significantly lower TSS and the TA was rather high for public consumption. The results of this investigation demonstrate a need for quality and grading standards in the international pomegranate trade and the potential for better quality control in the minimally processed prepackaged pomegranate aril market.
