abstract antioxidant capacity and quality of fruits usually changed during storage. in the current study, the changes of antioxidant capacity and postharvest quality of two blood (pigmented) orange cultivars (‘tarocco’ and ‘morro’) and ‘thompson navel’ orange, after 60 days storage at 7ºc and 90 rh% was investigated. during fruit storage weight loss, tss, ta, tss/ta, vitamin c, total phenol, an...

in this study, the possible infection of thomson navel, moro blood sweet orange, page mandarin and webber pomelo with citrus viroids was investigated. biological indexing was performed by grafting on etrog citron (c. medica) and maintained in temperature-controlled greenhouse. after inoculation, rna was extracted by sds– potassium acetate method. detection of citrus viroids was done reverse tra...

Traditionally, Sicilian blood oranges (Citrus sinensis) have been associated with cardiovascular health, and consumption has been shown to prevent obesity in mice fed a high-fat diet. Despite increasing consumer interest in these health-promoting attributes, production of blood oranges remains unreliable due largely to a dependency on cold for full color formation. We show that Sicilian blood o...

For many years the comparison of apples and oranges was thought to be impossible. Many authors use the analogy of the putative inability to compare apples and oranges as a means of scornfully reviewing the work of others. The titles of some recent publications 2 suggest an actual comparison of apples and oranges, but the authors do not, in fact, compare these two fruits. Our laboratory has been...

Magnetic resonance imaging (MRI) is applied for on-line inspection of fruits. The aim of this work is to address the applicability of MRI for freeze injury detection in oranges directly on a distribution chain. Undamaged and damaged oranges are conveyed at 50 and 100 mm/s by a specially designed conveyor within a 4.7 T spectrometer obtaining fast low-angle shot images. An automatic segmentation...

Young and unripe oranges and grapefruits stored at 15 degrees or 20 degrees evidenced shortly after harvest a marked increase in respiratory rate, and then a well-defined maximum which was followed by a decrease.Ethylene production by oranges (measured by the manometric method) was observed, with curves parallel to the respiratory curves.The respiratory upsurge was accompanied by color changes ...

Flavanones constitute the majority of flavonoids in citrus fruits such as sweet (Citrus sinensis) and sour oranges (C. aurantium) and their near relatives—tangerines/mandarins (C. reticulata), tangors and tangelos. The relevant chemical analytic literature was searched, abstracted, documented, standardized, examined for quality, enumerated, and summarized in a database for these citrus flavanon...
