Antioxidant activity of fresh and dry fruits commonly consumed in India

  Epidemiological studies from other parts of the world indicate that increased consumption of fruits and vegetables are associated with lower risk of chronic degenerative diseases. Fruits are an important component of Indian diets. Studies indicate that fruits and vegetables are rich sources of phenolic compounds and antioxidant activity (AOA). Present study was taken up […]

Changes in the key odorants of Italian hazelnuts (Coryllus avellana L. Var. Tonda Romana) induced by roasting.

Application of a comparative aroma extract dilution analysis on aroma distillates isolated from either raw Italian hazelnuts or a roasted hazelnut material produced thereof revealed 37 odor-active compounds in the raw nuts, whereas 46 aroma compounds were detected in the roasted nut material. 2-Methoxy-3-isopropylpyrazine and 2-methoxy-3,5-dimethylpyrazine as well as 5-methyl-4-heptanone predominated with the highest flavor […]

Health benefits of nut consumption.

Nuts (tree nuts and peanuts) are nutrient dense foods with complex matrices rich in unsaturated fatty and other bioactive compounds: high-quality vegetable protein, fiber, minerals, tocopherols, phytosterols, and phenolic compounds. By virtue of their unique composition, nuts are likely to beneficially impact health outcomes. Epidemiologic studies have associated nut consumption with a reduced incidence of […]

Survival and growth of salmonella in high-moisture pecan nutmeats; in-shell pecans; inedible nut components; and orchard soil

Outbreaks of salmonellosis associated with almonds have raised interest in better understanding the behavior of Salmonella on other tree nuts. We undertook a study to determine the survival and growth characteristics of Salmonella on high-moisture (water activity of 0.96 to 0.99) pecan nutmeats; in-shell pecans; and inedible components (shuck; shell; and middle septum tissue) of […]

Hepatoprotective effect and antioxidant role of sun; sulphited-dried apricot (Prunus armeniaca L.) and its kernel against ethanol-induced oxidative stress in rats

The present study was carried to evaluate the hepatoprotective effect and antioxidant role of sun; sulphited-dried apricot and its kernel against ethanol-induced oxidative stress. The hepatopreventive and antioxidant potential of the plant's supplementations were evaluated by measuring level of serum liver damage marker enzymes (AST; ALT; GGT and LDH); antioxidant defense systems (GSH; GR; SOD; […]

Effects of almond dietary supplementation on coronary heart disease lipid risk factors and serum lipid oxidation parameters in men with mild hyperlipidemia

Objectives: Oxidation and level of plasma lipids are closely implicated in the development of coronary heart disease (CHD). Dietary almond supplementation may participate in beneficial effects on CHD lipid risk factor levels and their susceptibility to oxidative modification. The aim of this study was to evaluate the effects of dietary supplementation with almond on serum […]

Chromatographic techniques for the determination of alkyl-phenols; tocopherols and other minor polar compounds in raw and roasted cold pressed cashew nut oils

Anacardium occidentale belongs to the family Anacardiaceae and is principally grown in tropical America (Mexico; Peru; Brazil; etc.) and India. Cashew nuts contain low amounts of hydroxy alkyl phenols that come from an oily liquid present in their shell and that is known as cashew-nut shell liquid. This paper reports the alkyl phenols composition of […]
