Antioxidant activities and chemical profiles of pyroligneous acids from walnut shell
Three kinds of pyroligneous acids were prepared from walnut shell at different temperature ranges (low: 90~150 °C; SP1; middle: 151~310 °C; SP2; and high: 311~550 °C; SP3). The chemical profiles of the acids were established by GC-MS. Antioxidant activities of the acids were investigated from the aspects of DPPH free radical scavenging capacity; hydroxyl free […]
CONTEXT: Hyperhomocysteinemia is caused by genetic and lifestyle influences; including low intakes of folate and vitamin B6. However; prospective data relating intake of these vitamins to risk of coronary heart disease (CHD) are not available. OBJECTIVE: To examine intakes of folate and vitamin B6 in relation to the incidence of nonfatal myocardial infarction (MI) and […]
Beliefs; benefits; barriers; attitude; intake and knowledge about peanuts and tree nuts among WIC participants in eastern North Carolina
The objective of this study was to assess beliefs (e.g. advantages; disadvantages; benefits; barriers) and knowledge about eating peanuts and tree nuts. Personal interviews based on the Theory of Planned Behavior were conducted to elicit beliefs about eating nuts. Then; a cross-sectional survey was administered to WIC participants from one county in North Carolina. One-hundred-twenty-four […]
Effect of Brazil nut supplementation on the blood levels of selenium and glutathione peroxidase in hemodialysis patients
OBJECTIVE: In patients who have undergone hemodialysis; large amounts of reactive oxygen species (ROS) are produced and; at higher concentrations; ROS are thought to be involved in the pathogenesis of cardiovascular disease. It has been proposed that selenium (Se) may exert an antiatherogenic influence by reducing oxidative stress. The richest known food source of selenium […]
Protective effect of anacardic acids from cashew (Anacardium occidentale) on ethanol-induced gastric damage in mice
Cashew nut-shell liquid and the contained anacardic acids (AAs) have been shown to possess antioxidant; lipoxygenase inhibitory; anti-Helicobacter pylori and antitumor properties. Despite these known effects; hitherto there were no published reports on their likely gastroprotective effects. The present study was designed to verify whether AAs afford gastroprotection against the ethanol-induced gastric damage and to […]
Detection of hazelnuts and almonds using commercial ELISA test kits
Three commercial sandwich enzyme-linked immunosorbent assay (ELISA) test kits for the detection of hazelnuts and almonds were evaluated. Limits of detection and dynamic ranges were determined for hazelnuts and almonds spiked into cooked oatmeal; dipping chocolate; and muffins (baked). The limit of detection values varied from 1 to 38 mug/g; depending on the food matrix […]
"Pine Mouth" Syndrome: Cacogeusia Following Ingestion of Pine Nuts (Genus: Pinus). An Emerging Problem?
.We report a case of cacogeusia; specifically metallogeusia (a perceived metallic or bitter taste) following pine nut ingestion. A 36-year-old male presented with cacogeusia one day following ingestion of 10-15 roasted pine nuts (genus: Pinus). Symptoms became worst on post-exposure day 2 and progressively improved without treatment over 5 days. There were no other symptoms […]
Nezara viridula (Hemiptera: Pentatomidae) feeding patterns in macadamia nut in Hawaii: nut maturity and cultivar effects
Nezara viridula L. (Hemiptera: Pentatomidae) is a serious pest of macadamia nuts; Macadamia integrifolia; in Hawaii. Using ruthenium red dye to stain stink bug feeding probes; feeding activity was determined for nuts of various maturity levels harvested from the tree and off the ground throughout the growing season in five commercial cultivars. Damage occurred in […]
Influence of ripeness and drying process on the polyphenols and tocopherols of Pistacia vera L
This paper highlights; for the first time; the changes in the phenolics fraction (anthocyanins; flavonoids and stilbenes) and tocopherols of unpeeled Pistacia vera L. var. bianca with ripening; and the effect of the sun-drying process. The total polyphenol levels in pistachios; measured as mg of Gallic Acid Equivalent (GAE); were: 201 +/- 10.1; 349 +/- […]
Effect of whole walnut and walnut-skin extracts on oxidant status in mice
OBJECTIVE: To evaluate the effect of the intake of whole walnuts and walnut fractions on the oxidant status in mice. METHODS: Thirty-six C57BL/6J male mice were randomized to be fed one of three diets: 1) a standard diet (control group); 2) a standard diet with 10% of whole walnuts (walnut-diet group); or 3) a standard […]
