Quality evaluation of pineapple fruit during drying process

Changes in the nutritional content of fruit and vegetables during the dehydration process of freeze drying

Lime, Gypsum, and Basaltic Dust Effects on the Calcium Nutrition and Fruit Quality of Pineapple

Pineapples grown in acid soils containing high levels of manganese (Mn) can exhibit iron deficiency because Mn interferes with iron bio-functioning. This situation is commonly corrected with regular iron sprays. Soil Mn concentration can be reduced by liming, but pineapple growers keep the soil pH below 5.0 because it helps reduce the incidence of rots caused by Phytophthora sp. This study was ...

Selective pruning in pineapple plants as means to reduce heterogeneity in fruit quality

Heterogeneity in fruit quality (size and taste) is a major problem in pineapple production chains. The possibilities were investigated of reducing the heterogeneity in pineapple in the field by pruning slips on selected plants, in order to promote the fruit growth on these plants. Slips are side shoots that develop just below the pineapple fruit during fruit development. Two on-farm experiments...

Heterogeneity in pineapple fruit quality results from plant heterogeneity at flower induction

Heterogeneity in fruit quality constitutes a major constraint in agri-food chains. In this paper the sources of the heterogeneity in pineapple in the field were studied in four experiments in commercial pineapple fields. The aims were to determine (a) whether differences in pineapple fruit quality among individual fruits are associated with differences in vigor of the individual plants within t...

Contents Changes of Triterpenic Acids, Nucleosides, Nucleobases, and Saccharides in Jujube (Ziziphus jujuba) Fruit During the Drying and Steaming Process.

Chinese jujube (Ziziphus jujuba), a medicinal and edible plant, is widely consumed in Asian countries owing to the remarkable health activities of its fruits. To facilitate selection of the suitable processing method for jujube fruits, in this study their contents of triterpenic acids, nucleosides, nucleobases and saccharides after drying and steaming treatment were determined using ultra-high ...
