oxidative stability of walnut (juglansregia l.) was evaluated over a period of 1 year storage in various conditions. the whole walnuts, walnut kernels, walnut chopped kernels, walnut kernels packaged in polyethylene (pet) under vacuum and poly propylene (pp) contain of co2 were kept in a normal condition (temperature, 19-30˚с and relative humidity (rh), 35-45%). the whole walnuts and walnut ker...

BACKGROUND Walnut hydrosol (WH) is used extensively by Iranian people with diabetes in order to control blood sugar (BS). There are few data regarding the effect of walnut on controlling diabetes. OBJECTIVES A pilot study to determine the efficacy and safety of WH in patients with type 1 diabetes. MATERIALS AND METHODS Eight patients with diabetes mellitus (DM) type 1 were enrolled in the s...

The phenolic extracts of walnut cultivars with a red pellicle (HWE), purple (ZWE) and yellow (WWE) were compared. total contents phenolics, flavonoids condensed tannins, as well in vitro antioxidant activities (ABTS DPPH) the evaluated. results showed that 25 compounds identified three colored walnuts. HWE contained highest phenolics while ZWE content flavonoids. DPPH ABTS assays indicated colo...

The rancidification of walnuts was promoted by storing shelled kernels at 38°C for 4 weeks. Of six varieties tested, only 'Howard' and 'Chandler' kernels went rancid during this period. Their deterioration was preceded by the appearance of lipase (an oil digesting enzyme) in kernels and an accumulation of free fatty acids in the oil. The implications and limitations of these observations are di...

Seven pure-culture strains of fungi cultivated by attine ants (ant-garden fungi) were isolated from locally maintained leaf-cutting ant colonies. An ant-garden fungus strain obtained from an Atta cephalotes colony, when offered to ants of the colony from which the fungus was isolated, was accepted as their own. Young fungus cultures were harvested and incorporated into the fungus garden, and cu...

Roasting has considerable effects on the quality of cream made of nuts. In this study, the roasting conditions of walnut kernels were optimized based on the stability parameters of the produced cream. Temperatures of 100-150°C for 10-30 minutes were used to roast walnut kernels. The amount of oil separation, peroxide, acidity and Thiobarbituric acid values of the cream, as well as color paramet...

the first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. hence, there are various walnut breeding programs in various areas of iran. a study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the shahroud region in 2011-2012.  the following genotypes were selected in this stu...

This review presents a comprehensive synthesis of walnut oil chemical composition data (major and minor compounds) collected from the literature according to varieties geographic origins walnuts, extraction processes. Considered as influencing factors, pre- post-harvest treatment parameters in shell-walnut kernels were identified works on stability discussed pre-treatment, processes their stora...

s that included only subjects who had a non-CVDrelated condition (e.g., cancer, schizophrenia, or organ transplant), letters, and abstracts. Upon review of full articles we excluded studies of children (under age 19 years), studies of daily omega-3 fatty acid doses of more than 6 g per day, studies of less than 4 weeks duration, crossover studies with less than 4 weeks washout between treatment...
