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...

With juices of grapefruit and related fruits, possible relationships between contents of six different furanocoumarins and extents of inhibition of microsomal CYP3A activity have been studied in vitro. Microsomal CYP3A-mediated testosterone 6beta-hydroxylation was inhibited by the addition of a fruit juice (2.5%, v/v) from eight different grapefruit sources, two sweeties, three pomelos, and one...

Hydro-Distillation (HD), Cold Pressing (CP) and Microwave Clevenger or microwave Accelerated Distillation (MAD) methods have been compared and evaluated for their efficiency in the extraction of essential oil (EO) from fresh Citrus peels. EO from peel of 4 varieties of Algerian sweet orange (C. sinensis), Lemons (C. limon), Citrons (C. medica), sour orange (C. aurantium), grapefruits (C. paradi...

This study investigated sweet–sour taste interactions in novel sweeteners using a 3 × 2 factorial design consisting of Sweetening System (three levels: sucrose; d-allulose; and blend d-allulose Monk fruit extract) Acidity (two with or without citric acid). 110 untrained Chinese subjects participated the temporal check-all-that-apply (TCATA) method. Mixed-model ANOVA was conducted to investigate...

Grafting influences scion photosynthetic capacity and fruit quality. Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), which strongly affects photosynthetic rate, and Rubisco activase (RCA), which regulates Rubisco activity, are two key photosynthetic enzymes. However, little information is available regarding the effect of grafting on the concentration and expression of Rubisco and RC...

Citrus is one of the most important and widely grown fruit crop with global production ranking firstly among all the fruit crops in the world. Sweet orange accounts for more than half of the Citrus production both in fresh fruit and processed juice. We have sequenced the draft genome of a double-haploid sweet orange (C. sinensis cv. Valencia), and constructed the Citrus sinensis annotation proj...

Micro- and macro-element contents of several commercial fruit juices purchased from marked were determined by inductively coupled plasma atomic emission spectroscopy. Among the minor elements determined, Zn, Cu, Mn, Mo, Co, Cd and Ni were found to be lover. Major mineral contents of fruit juices were established as Ca, K, Mg and P. The potassium contents of fruit juices were determined at the h...

Studies have shown that smokers rationalize smoking by self-exempting beliefs. This study explored lay beliefs about smoking in Kelantan, Malaysia, using focus groups among outpatients, medical students and staff, and a questionnaire survey of 193 male smokers. In focus groups, patients said they could do something to make smoking safe. When asked, 'Do you think there are any safe ways to smoke...

IN T RODUC T ION QuEChERS methodology is commonly used for sample preparation of fruits and fruit juices, prior to LC/MS or other analytical chromatography. Recently, a nonregistered fungicide residue, carbendazim, was detected in orange juice purchased at a local market. This juice was produced from orange juice concentrate imported into the USA. In this application note, we discuss sample pre...

late ripening citrus cultivars are very acceptable in the market. with respect to scarcity of late ripening citrus cultivars in iran, the project was conducted to produce a new late ripening cultivar for 21 years (1989-2009). the first phase (1989-1993) was started with controlled pollination between mineolla tangelo (citrus paradisi × c. reticulata) and changsha mandarin (c. changsha). after a...
