Excessive seed hardness and wood perception will drastically limit consumer's acceptance for pomegranate. To classify pomegranate cultivars, easy-to-measure instrumental texture parameters and consumer satisfaction degree were assayed. Twenty pomegranate cultivars (sweet, sour-sweet and sour tastes) with a wide range of seed hardness were used. The instrumental hardness ranged from 9.60 to 59.5 N/mm, whereas the wood index ranged from 4.77 to 15.3%. Classifications based on hardness and wood perception agreed quite well. Cultivars MA3, ME14, MO5, PTO10 or VA1 were classified as appropriate for fresh consumption whereas cultivars BO1, HZ and WOND were classified as appropriate for industrialization. Cultivars ME12, MEC, MO2 and VA11 were finally recommended for fresh consumption not only due to low seed hardness and intermediate wood perception but also due to sweet taste; however, cultivars BA1 and SM were recommended for industrialization because of its sour taste, which is normally not acceptable to consumers. Finally, the cultivar PTO5 can be used for both purposes, as needed. PRACTICAL APPLICATIONSBecause of market demand, it is important to characterize different pomegranate cultivars, not only to classify them in terms of their beneficial properties but also to gather information about the effects of texture attributes (seed hardness and wood perception) on consumer acceptance. Regressions of (1) seed hardness and wood perception versus descriptive hardness and (2) descriptive hardness and wood perception versus instrumental hardness and wood index allowed the classification of pomegranate cultivars according to their final use (fresh consumption and/or industrialization, mainly juice manufacturing).

BACKGROUND Scanning electron microscopy was assayed and linked with previous data with respect to obtaining a new combined sensory‐instrumental tool for pomegranate seed hardness determination. The present study aimed to develop an effective tool for the prediction of sensory properties via instrumental determinations. RESULTS Simple regression analysis determined a high correlation within descriptive seed hardness and thickness of the wall, as well as descriptive wood perception and thickness of the wall, with values of 0.71 in both cases. Multiple regression analysis improved correlations when (i) descriptive seed hardness correlated with instrumental seed hardness and wood index (0.94); (ii) descriptive wood perception correlated with instrumental seed hardness and wood index (0.79); (iii) descriptive seed hardness correlated with instrumental seed hardness and thickness of the seed wall (0.96); and (iv) descriptive wood perception correlated with instrumental seed hardness and thickness of the seed wall (0.82). The same trend was found when (i) seed hardness satisfaction degree correlated with instrumental seed hardness and wood index (0.92); (ii) wood perception satisfaction degree correlated with instrumental seed hardness and wood index (0.82); (iii) seed hardness satisfaction degree correlated with instrumental seed hardness and thickness of the wall (0.99); and (iv) wood perception satisfaction degree correlated with instrumental seed hardness and thickness of the wall (0.99). CONCLUSION Regarding mechanical properties, the results of the present study confirm that texture analysis and scanning electron microscopy are an effective tool for obtaining reliable information. This research led to establish an objective tool allowing prediction of the consumer acceptance of pomegranate cultivars worldwide. © 2020 Society of Chemical Industry
