“…Total phenolic compounds determined as the sum of individual compounds ranged from 308.06 AE 30.62 to 476.10 AE 26.10 mg/L, with the highest amounts being recorded in SV variety. These results are in agreement with those reported in OJs from different varieties (Dhuique-Mayer et al, 2005;Kebelek et al, 2009;Rapisarda et al, 2008).…”

Antioxidant capacity was evaluated by a cellular model (Saccharomyces cerevisiae) and chemical methods (FRAP, TEAC and total phenols by Folin-Ciocalteu assay) in the hydrophilic fraction (phenolic compounds and ascorbic acid) of orange juices (OJs) from six varieties (Midknight, Delta Seedless, Rohde Red, Seedless, Early and clone Sambiasi), harvested in two seasons. The contents of phenolic compounds and ascorbic acid analyzed, respectively, by UPLC and HPLC were 370.04 76.97 mg/L and 52.05 6.69 mg/100 mL. Variety and season significantly influenced (p < 0.05) composition and antioxidant capacity. TEAC and FRAP values correlated well with individual hydrophilic compounds (R2 > 0.991) but no correlation with cellular assay was observed. An increase in survival rates between 23% and 38% was obtained, excepting for two varieties that showed no activity (Rohde Red and Seedless). Narirutin, naringin-d, ferulic acid-d2, didymin, neoeriocitrin and sinapic acid hexose and caffeic acid-d1 were the phenolic compounds which contributed to survival rates (R2 = 0.979, p < 0.01

“…Differences in vitamin C is influenced by differences in varieties, cultivation practices, level of maturity, fresh fruit handling, packaging and storage conditions (Nagy et al, 1977). Vitamin C is also much influenced by temperature and storage time (Rapisarda et al, 2008). On the sweet orange, vitamin C is largely derived from ascorbic acid (90%) and less than 10% of the dehydroascorbic acid (DHA) (Ladaniya, 2008).…”

Indonesia has number of accessions and cultivars of pummelo which are prospective to be developed. Pummelo contains higher antioxidants thus beneficial for health. This research aimed to get information of physical and chemical quality differences, antioxidant capacity, and explain the relationship between fruit quality and antioxidant capacity of selected seeded pummelo cultivars. Fruit was harvested in Banyuwangi and Magetan while fruit quality assesment was conducted in Laboratory of Agronomy and Horticulture Department, IPB. The results showed that physical qualities of fruit (weight loss, peel softness and peel color) and chemical qualities (total soluble solids and total titratable acidity) were changed during storage. Adas Nambangan and Banyuwangi cultivars have better physical and chemical qualities than other cultivars during storage until 10 weeks after harvest because of good visual appearance, the lowest decreased in weight loss and the good ratio of TSS:TTA. Seeded pummelo cultivars with dark red to reddish white fruit pulp had significant higher total phenolic, carotenoid, anthocyanin and antioxidant capacity than white fruit pulp. There were negative correlations between antioxidant capacity with colored pulp and total phenolic content. Banyuwangi had the highest antioxidant capacity in the pulp, followed

-Introduction. Albedo breakdown (AB) causes serious economic losses to sweet orange growers. The growers practice delayed harvesting (tree storage) to extend the fresh fruit supply to market. We investigated the effects of tree storage and cold storage on AB incidence, textural properties of the rind and fruit quality. Materials and methods. Fruit of 'Washington Navel' orange were harvested at the commercial maturity stage (3 rd July) and then 31, 62 and 93 days after the harvest. The AB incidence, textural properties of the rind and fruit quality were assessed in one lot of fruit after harvest and a second lot after 31, 62 and 93 days of cold storage (5 • C). Results and discussion. The AB incidence increased from 65% to 89% from the first to the last harvest, respectively. Extended storage periods reduced rind hardness and fruit firmness, and increased the rind tensile force irrespective of the storage type. The rind hardness, tensile force and fruit firmness were higher in cold-stored fruit than fruit stored for 93 days on the tree. The soluble solids concentration: titratable acidity (SSC:TA) ratio in juice increased with the extended storage period in both types of storage. The increase in SSC:TA was more pronounced at 62 and 93 days in cold-stored than tree-stored fruit. The concentrations of fructose and glucose in the juice of fruit stored on the tree for 93 days were higher than in the cold-stored fruit, and sucrose showed the reverse trend. Conclusion. The cold-stored fruit exhibited a higher rind hardness, rind tensile force, firmness and SCC:TA ratio, lower concentrations of citric acid, malic acid, fructose and glucose, and lower AB incidence than the tree-stored fruit. These findings indicate a preference for cold storage over tree storage for the orange fruit quality.Keywords: Australia / sweet orange / Citrus sinensis L. / albedo breakdown / sugar composition / fruit rind texture / ripening Résumé -Influence de la conservation sur l'arbre ou au froid des oranges « Navel de Washington » sur l'incidence des désordres d'albédo, les propriétés de texture de la peau et la qualité des fruits. Introduction Les désordres d'albédo (AB) provoquent de lourdes pertes économiques pour les producteurs d'oranges douces. La pratique courante des producteurs pour retarder la récolte (stockage sur l'arbre) permet d'étendre l'offre en fruits frais sur le marché. Nous avons étudié les effets du stockage sur l'arbre ou au froid sur l'incidence d'AB, sur les propriétés de texture de la peau et la qualité des fruits. Matériel et méthodes. Les oranges 'Washington Navel' ont été récoltées au stade de maturité commerciale (3 juillet), puis 31, 62 et 93 jours après la récolte. L'incidence d'AB, les propriétés de texture de la peau et la qualité des fruits ont été évalués à partir d'un lot de fruits juste après la récolte et d'un autre lot stocké froid (5 • C) pendant 31, 62 et 93 jours. Résultats et discussion. L'incidence d'AB a augmenté de 65 % à 89 % entre la première et la dernière récolte, respectivement. Les...
