Effects of Site and Cultivar on Consumer Acceptance of Pomegranate

Pomegranate (Punica granatum L.) is an important fruit in many cultures. The fruit and juice have risen in popularity as it was discovered that pomegranate has relatively high antioxidant activity compared to most other fruits. In this study, six cultivars were utilized to determine consumer acceptance compared to the industry standard, 'Wonderful,' which comprises 90% to 95% of commercial production in the United States. Fruit were sourced from 2 cultivar field trials, one in inland Riverside, California, and one in coastal Ventura County, California. Cultivars selected for the study included 'Eversweet,' 'Green Globe,' 'Haku Botan,' 'Loffani,' 'Phoenicia,' 'Wonderful,' and 'cv. 857,' an heirloom cultivar from Ventura County, CA, U.S.A. Pomegranate arils were subject to sensory evaluation by 87 untrained consumer panelists in late 2016. Panelists were given pomegranate arils and asked to score the samples using a 9-point Hedonic scale for the following fruit quality traits: aril color, sweetness, tartness, seed hardness, bitterness, and overall desirability. There were significant differences among cultivars for all traits assessed by the sensory panelists. There were differences in acceptance among consumers for 'Wonderful' depending on if it was grown on the coast versus inland, and consumers preferred inland- versus coastal-grown 'Wonderful.' 'Wonderful' pomegranate was associated with cultivars that consumers scored low on desirability for bitterness. Cultivars that scored well in overall desirability compared with 'Wonderful' were 'cv. 857,' 'Eversweet,' 'Green Globe,' and 'Phoenicia.'

Consumer sensory panels are important to determine scientifically which cultivars are desired by the public. These panels allowed for the determination of which pomegranate cultivars are liked or disliked by consumers and why. If the pomegranate growers know the most desirable cultivars for consumers, they are more likely to adopt and plant them, thus potentially increasing the diversity in the marketplace, as has been with apples, peaches, plums, pears, mangoes, strawberries, raspberries, blueberries, and citrus.
