The development of delayed bitterness in citrus products is a major problem to citrus producers and juice processors worldwide. A rapid and sensitive liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS) method has been developed to quantify the recognized precursors of limonoid derived delayed bitterness, limonoate and nomilinoate A-ring lactones, in a wide variety of cit...

Immediate allergic reactions to orange are rare and immunoglobulin (Ig) E–mediated [1]. We report the case of a 28-year-old man with anaphylaxis induced by fresh orange juice. The reaction was dose-dependent and could only be confi rmed by challenge test, because specifi c IgE to orange was undetectable by skin prick test (SPT) and CAP immunoassay. The patient had experienced identical anaphyla...

A machine vision system for estimating number of citrus fruit drop was developed in this study. The objectives of this study were to design rugged hardware, to develop an image processing algorithm for accurate estimation of fruit count and to conduct field experiments. Image acquisition hardware was developed to be used in a commercial citrus grove specifically for unfavorable imaging conditio...

OBJECTIVE To examine the effectiveness of two methods of increasing fruit and fruit juice intake in pregnancy: midwives' advice and vouchers exchangeable for juice. DESIGN Pregnant women were randomly allocated to three groups: a control group, who received usual care; an advice group, given advice and leaflets promoting fruit and fruit juice consumption; and a voucher group, given vouchers e...

Fruit ripening in citrus is not well-understood at the molecular level. Knowledge of the regulatory mechanism of citrus fruit ripening at the post-transcriptional level in particular is lacking. Here, we comparatively analyzed the miRNAs and their target genes in a spontaneous late-ripening mutant, "Fengwan" sweet orange (MT) (Citrus sinensis L. Osbeck), and its wild-type counterpart ("Fengjie ...

During the last decade there has been a continuous rise in consumption of fresh easy-to-peel mandarins. However, mandarins are much more perishable than other citrus fruit, mainly due to rapid deterioration in sensory acceptability after harvest. In the current review we discuss the biochemical components involved in forming the unique flavor of mandarins, and how postharvest storage operations...

Effects of foliar spray NAA, 2, 4-D and urea on fruit yield quality Citrus limon (L.) Burm. cv. Assam lemon was studied. Nine treatments were imposed in RBD for two seasons (summer winter). Among the T6 (NAA @ 20 ppm + 2,4-D 1% urea) maximum pulp content (81.58 g/fruit), juice (40.47 ml/fruit), reducing sugar (0.51%) ascorbic acid (48.56 mg/100 g) recorded. Whereas, TSS (9.88%), total (1.66%) w...

Analytical methods useful for routine applications are ideally low-cost, simple to perform, and yield rapid results which are easy to interpret. Chroma tog raphic methods, par ticularly of complex samples such as fruit juice, are often difficult, can be expensive and time-consuming, and may yield results devoid of interpretation. With the proper choice of detector, the chromatographic analysis ...

Naringenin, a flavonoid belonging to the flavanones subclass has been reported have several promising biological activities like antioxidant, antitumor, anticancer, antiviral, anti-inflammatory & estrogenic activities. Naringin is found in glycosidic form citrus fruits grapefruit, orange, and lemons. Naringenin obtained by hydrolysis of glycoside naringin. In present study, environmentally ...
