Pomegranate Quality from Consumers' Perspective: Drivers of Liking, Preference Patterns, and the Relation between Sensory and Physico-Chemical Properties.

Acquiring information on consumer preferences for the sensory properties of pomegranates is a cue for breeding programmes to set their quality targets and promote the consumption of this particularly healthy fruit. In this study, a total of 12 pomegranate varieties were evaluated, including commercial (Valenciana, Illina, Tastem, Rugalate, Wonderful, Mollar 49 y Mollar 45) and new varieties (Ref 102, Ref 383, H3/27, and D27/12). For the first time, consumers not only scored their acceptance of different pomegranate varieties but also described their sensory properties using CATA questions. This approach allowed us to identify the main drivers of liking, preference patterns, and the relationship between sensory and physico-chemical properties. Of all the sensory attributes, acidity intensity was revealed as the main driver of liking/disliking, and two different consumer preference patterns were identified: 'low acid pomegranate lovers' and 'acid pomegranate lovers'. Seed properties like the intensity of woody flavour and seed/aril ratio were also key drivers for preferences. A relationship between sensory and physico-chemical properties was also established. Interestingly, sweetness perception correlated more strongly with low titratable acidity levels than with high total soluble solids levels, corroborating that acidity level is a key measurement for quality assessments. 'H3/27' was the most promising of the new varieties for having the well-appreciated internal properties of the 'Mollar' varieties and external and internal red colouration, which makes it much more appealing to consumers. This study shows that there is still room on the market for pomegranate varieties with very different sensory properties and highlights the need to develop sensory labels that help consumers make the right choices.

Influence of Pomegranate Appearance Attributes on Consumer Choice, and Identification of Barriers and Drivers for Consumption.

In a prepurchase situation, consumers base their choice decision on external fruit characteristics, from which they infer internal characteristics. This study investigates consumer preference for pomegranate appearance using a choice-based conjoint analysis with 320 participants. We created 27 images of pomegranates that differed in varietal characteristics: colour (yellow, bicoloured, and red), shape (round, oval, and flattened), and calyx shape (open, semi-open, and closed). Colour was by far the most important factor for consumers, followed by fruit shape and calyx shape. Two preference profiles were identified. Most consumers liked bicolour and red pomegranates equally, and rejected yellow ones, while a smaller group concentrated their choice on bicolour pomegranates. In terms of fruit and calyx shape, oval and flattened fruit and open calyx were the most preferred by both consumer groups. Barriers and drivers for consumption were also investigated. There is still plenty of room to increase pomegranate consumption. Greater availability of pomegranates and ready-to-eat arils in grocery shops, obtaining new unseeded/easier-to-peel varieties, and providing a sensory label would help to overcome current barriers. Marketing campaigns should focus on a pomegranate's health benefits and its versatility in consumption.

Acceptance, Sensory Characterization and Consumption Contexts for Dehydrated Persimmon Slices, Chips, Leathers and Powder: A Consumer Study.

Valorization of persimmon discards is a current challenge for the food industry. Obtaining dehydrated persimmon products can be a good option, but studies are necessary to predict consumer responses before placing new products on the market. In this study, we produced dried slices, chips, leathers and powder from persimmons that were discarded at harvest. A consumer study was performed with 100 participants. For a realistic context, the four products were presented to the participants in specifically designed packages to simulate commercial packages. The participants were asked about their interest in having each product available on the market. Then, they were asked to taste the samples and to state their acceptance and purchase intention. The participants characterized the main sensory properties of the samples using the CATA questions. The consumption contexts evoked by each product were also investigated based on the item-by-use method, plus the CATA questions. Our results revealed that, before tasting the samples, the participants showed special interest in having chips and slices available on the market. After tasting, the participants reported very good acceptance of chips, slices and powder, but leathers were less liked. According to the consumer characterizations, slices had the most intense persimmon taste and a succulent texture, while powder was characterized by its caramel taste. Chips were differentiated from the other samples, mainly for their crispy texture, while leathers were sticky and tasteless, which explained their poor acceptance. By evaluating the data on acceptance and the evoked consumption contexts together, we conclude that persimmon consumption could be enhanced by commercializing slices, chips and powder. The participants described chips and slices as healthy snacks in different daily situations, while powder could be used as a sweetener for yoghurts or hot drinks and as an ingredient for baking desserts. These are all contexts in which fresh persimmon would be not consumed as reported by the participants.
