Corn bran was subjected to high-shear and jet-cooking with or without alkaline treatment. The highest antioxidant activity was found in the soluble solids from jet-cooked corn bran without alkaline treatment. Jet-cooking under alkaline conditions resulted in a soluble fraction having the highest phenolic content but without increasing antioxidant activity. Phenolic contents of soluble solids we...

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...

Cell-free systems that catalyze the condensation of acetylcoenzyme A to form long chain fatty acids have been prepared from chicken liver by Wakil et al. (l), from yeast by Lynen (2), and from rat liver and brain by Brady, Bradley, and Trams (3, 4). In 1957, Stumpf and Barber (5) described a mitochondrial system isolated from avocado mesocarp that incorporated (Y-acetate into long chain fatty a...

In recent years, excessive use of chemical fertilizers and lack of organic fertilizers caused to reduce the rate of soil organic matter in Iran. The increased use of chemical fertilizers in agriculture causes environmental problems such as soil physical degradation and soil nutrient imbalances. This study was conducted to investigate the effects of foliar and soil applications of humic acid on ...

In this experiment the effect of edible coating (apricot gum) was used to extend the shelf life of apple slices. The edible coating was applied at different concentrations i.e. 0.5, 1, 2 and 3%. Physicochemical characteristics of edible coated apple slices were analyzed at different time intervals. The analysis was carried out for 12 days with an interval of 4 days. Results showed that the trea...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

The effects of salicylic acid (SA) and Putrescine (Put), on cut Gladioluswas studied. SA (0, 150, 300 and 450 mg l-1) and Put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 192 Gladioluscut flowers in horticulture laboratory of agriculture faculty of...
