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 […]
Antioxidant Potential of Chestnut (Castanea sativa L.) and Almond (Prunus dulcis L.) By-products
The antioxidant properties of almond green husks (Cvs. Duro Italiano; Ferraduel; Ferranhês; Ferrastar and Orelha de Mula); chestnut skins and chestnut leaves (Cvs. Aveleira; Boa Ventura; Judia and Longal) were evaluated through several chemical and biochemical assays in order to provide a novel strategy to stimulate the application of waste products as new suppliers 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; […]
The effectiveness of dried cranberries (Vaccinium macrocarpon) in men with lower urinary tract symptoms
Lower urinary tract symptoms (LUTS) are a common condition in older men. The objective of the present study was to evaluate the efficacy and tolerability of cranberry (Vaccinium macrocarpon) powder in men at risk of prostate disease with LUTS; elevated prostate-specific antigen (PSA); negative prostate biopsy and clinically confirmed chronic non-bacterial prostatitis. Forty-two participants received […]
Differential effects of walnuts vs almonds on improving metabolic and endocrine parameters in PCOS
Background/Objectives: Polycystic ovary syndrome (PCOS) is commonly associated with insulin resistance; dyslipidemia and increased inflammation; which all benefit from dietary intake of monounsaturated and n-3 polyunsaturated fatty acids (MUFA and n-3 PUFA). Our goal was to compare the effects of MUFA-rich almonds vs n-3/n-6 PUFA-rich walnuts on metabolic and endocrine parameters in PCOS.Subjects/Methods: Thirty-one PCOS […]
Almond tree and organic fertilization for soil quality improvement in southern Italy
The semi-arid Mediterranean region; characterized by long dry periods followed by heavy bursts of rainfall; is particularly prone to soil erosion. The main goal of this study is to evaluate the soil quality under different practices of bio-physical amelioration which involve the soil-plant system (almond trees) and microorganism-manure. This study; carried out in the South […]
Improving fruit quality; nutritional value and yield of Zaghloul dates by the application of organic and/or mineral fertilizers
A field study was carried out during the years 2007 and 2008 on 30-year old Zaghloul cultivar growing in clay soil. Mineral fertilization sources: N; ammonium nitrate or NPK; ammonium nitrate + calcium superphosphate + potassium sulphate; and organic sources: chicken manure (CM); cow dung (CD) and composted domestic refuse (CDR) were applied either alone […]
