mango (mangifera indica l.) production is on the rise in various subtropical zones throughout the world. the cultivation of this fruit tree is feasible along the coast of granada, where some 1,500 ha are presently grown. in 2006, the eu exported 118 thousand tonnes of mangoes at a value of 131 million euros. this study was conducted to assess the physico-chemical quality characteristics of some...

Orange press liquor is a by-product generated by the citrus processing industry containing huge amounts of natural phenolic compounds with recognized antioxidant activity. In this work, an integrated membrane process for the recovery of flavonoids from orange press liquors was investigated on a laboratory scale. The liquor was previously clarified by ultrafiltration (UF) in selected operating c...

The present study was conducted on five ber (Ziziphus mauritiana Lamk) cultivars (Komethry, Pakstany, Um-sulaem, Toffahy and Peyuan) grown in Saudi Arabia during 2005 and 2006 seasons. The aim of the present study was to investigate fruit properties (fruit weight, length, diameter, shape, specific gravity, seed weight, pulp percentage, total soluble solids (TSS), acidity percentage, TSS/acid, v...

The current experiment was carried out to determine the effect of application ethephon on maturation “Peter” figs. Fig fruits were treated with three aqueous concentrations (500, 1000, and 1500 ppm) during developmental stage. physic-chemical characteristics, such as fruit weight, length, diameter, total soluble solids (TSS), acidity recorded analysed. results showed that period fig significant...

studies have shown that oxygenated compounds and tss/ta are important for beverage and food industries. it seems that citrus rootstocks have a profound influence on oxygenated compounds and tss/ta. the aim of this research is to identify rootstock that can synthesize the maximum level of oxygenated compounds and tss/ta. peel oil was extracted using mechanical presses and eluted using n-hexane. ...

Apple is one of the most important fruits in temperate zones with a long post-harvest life during cold storage. A factorial experiment, in a randomized completely block design was used to investigate the preharvest application of Iron (0, 500 and 1000 mg Fe-EDDHA per tree) and nitrogen (0, 48 and 96 g ammonium nitrate per tree( on some postharvest qualitative characteristics in "Red spur" and "...

The peel volatile constituents and juice quality parameters of four tangerine cultivars were investigated in this study. Peel flavor constituents were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from tangerine cultivars. F...

The effects of mandarin scions on peel components and juice quality parameters were investigated in this study. Peel flavor components were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. Twenty-seven, Tw...

the use of natural compounds to control plant pathogens lead to reduction in using fungicides. chitosan with duble effects, control pathogenic microorganisms and activate inducing defence responses, has been shown to be a reliable nontoxic material in the plant-pathogen interaction. the aim of this research was to consider the effects of chitosan and calcium chloride on decay and quality attrib...

the effects of mandarin scions on peel components and juice quality parameters were investigated in this study. peel flavor components were extracted by using cold-press and eluted by using n-hexane. then all analyzed by gc-fid and gc-ms. total soluble solids, total acids, ph value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. twenty-seven, tw...
