Confirmation/disconfirmation of consumers' expectations about fresh and processed tropical fruit products

INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 3 2009
Sara Sabbe
Summary This study investigates tropical fruit acceptance in terms of confirmation or disconfirmation of consumers' general expectations. Consumers evaluated multiple product attributes before and after tasting five fresh and five processed tropical fruit products. Consumers' general expectations were confirmed after tasting persimmon (Diospyros kaki L.) and cashew apple juice (Anacardium occidentale L.). Positive disconfirmation occurred after the consumption of cherimoya (Annona cherimola Mill.) and berrycactus jam (Myrtillocactus spp.) whereas expectations were negatively disconfirmed after consuming dragon fruit (Hylocereus spp.), mangosteen (Garcinia mangostana L.), tree tomato (Solanum betaceum Cav.), açaí juice (Euterpe oleracea Mart.), baobob juice (Adansonia digitata L.) and tamarind jam (Tamarindus indica L.). Sensory experiences are demonstrated to greatly influence the acceptance and purchasing intention of tropical fruits and their products, as well as to affect consumers' perceptions about the product's health and nutritional benefits, in particular in cases where negative taste disconfirmation occurred.

EFFECT OF STORAGE TEMPERATURE AND TIME ON QUALITY IN MINIMALLY PROCESSED LITCHI FRUIT (LITCHI CHINENSIS SONN.)

JOURNAL OF FOOD QUALITY, Issue 3 2010
ELIA NORA AQUINO BOLAÑOS
ABSTRACT Rind browning is the most serious marketing problem for litchi (Litchi chinensis Sonn.) fruit, although it has no effect on the quality of the edible aril portion. Physicochemical, biochemical and subjective quality evaluations were done in minimally processed (peeled and vacuum-packed) litchi cv. Racimo Rojo fruit stored 18 days at 2, 5 or 10C. Little change was observed in total soluble solids, titratable acidity and pH, independent of storage temperature. Polyphenol oxidase (PPO) activity decreased, total phenolic compound content remained unchanged and peroxidase (POD) activity increased during storage. Correlation was low (<0.63) between color parameters (L*, a*and b*) and PPO and POD activities, and phenolic compounds. The minimally processed fruit stored at 2C exhibited characteristics similar to fresh fruit, whereas those stored at 5 and 10C emitted disagreeable odors that lowered their subjective quality. PRACTICAL APPLICATIONS The insignificant physicochemical changes observed here suggest that when stored at 2C, litchi fruit can be offered as a minimally processed product with characteristics similar to fresh fruit. Unlike most other minimally processed fruit products and other litchi varieties, pulp browning was not a significant problem in litchi cv. Racimo Rojo after peeling, providing it a potential commercial advantage. [source]


The bioavailability and absorption of anthocyanins: Towards a better understanding

MOLECULAR NUTRITION & FOOD RESEARCH (FORMERLY NAHRUNG/FOOD), Issue 6 2007
Tony K. McGhie
Abstract Evidence that anthocyanin compounds have beneficial effects for health are increasingly being reported in the scientific literature and these compounds are now widely recognised as potential therapeutic compounds. Berry fruit are rich sources of anthocyanins and berry fruit products or derived beverages can provide 10s to 100s of milligrams of anthocyanins in a single serve. Anthocyanins exhibit complex chemical behaviours in vitro and this will result in complex behaviour in vivo. This review attempts to summarize some aspects of anthocyanin biochemistry and discusses these in the context of what is currently known about bioavailability and absorption. Compared with other flavonoid groups, such as flavonols, relatively little is known about details and mechanisms of anthocyanin absorption and transport and much remains to be discovered. [source]
