Determination of fatty acid composition of -irradiated hazelnuts; walnuts; almonds; and pistachios
Hazelnut; walnut; almonds and pistachio nuts were treated with 1; 3; 5; and 7 kGy of gamma irradiation. Oil content; free fatty acid; peroxide value and fatty acid composition of the nuts were investigated immediately after irradiation. The data obtained from the experiments indicated that gamma irradiation did not cause any significant change in the […]
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 […]
Identification of the 100 richest dietary sources of polyphenols: an application of the Phenol-Explorer database
BACKGROUND/OBJECTIVES: The diversity of the chemical structures of dietary polyphenols makes it difficult to estimate their total content in foods; and also to understand the role of polyphenols in health and the prevention of diseases. Global redox colorimetric assays have commonly been used to estimate the total polyphenol content in foods. However; these assays lack […]
Phenolic Compounds and Antioxidant Activity of Kernels and Shells of Mexican Pecan (Carya illinoinensis).
The phenolic composition and antioxidant activity of pecan kernels and shells cultivated in three regions of the state of Chihuahua; Mexico; were analyzed. High concentrations of total extractable phenolics; flavonoids; and proanthocyanidins were found in kernels; and 5-20-fold higher concentrations were found in shells. Their concentrations were significantly affected by the growing region. Antioxidant activity […]
Pinolenic acid inhibits human breast cancer MDA-MB-231 cell metastasis in vitro
Pinolenic acid (PNA); a naturally-occurring polyunsaturated fatty acid (PUFA); is found mainly in pine seeds. Although many studies have demonstrated beneficial effects of pine seed oil; there are no reports of the biological effects of PNA on cancer metastasis. The objective of this study was to investigate the effect of PNA on human breast cancer […]
Body mass interacts with fat quality to determine the postprandial lipoprotein response in healthy young adults
BACKGROUND AND AIMS: Postprandial lipemia predicts the evolution of cardiovascular disease. Obesity is associated with an increase in the magnitude of postprandial lipemia. Our objective was to evaluate the influence of body mass index (BMI) on the effects of acute ingestion of different types of fat on the postprandial lipemic response. METHODS AND RESULTS: Twenty-one […]
Cultural and historical aspects of Mediterranean nuts with emphasis on their attributed healthy and nutritional properties
BACKGROUND AND AIMS: Nuts have been part of the human diet since prehistoric times. The aim of the present article is to describe the most important historical and cultural aspects of nut consumption throughout history. DATA SYNTHESIS: We discuss the following historical aspects of nuts originating in the Mediterranean: prehistory; the Egyptian civilization; their spread […]
Most-probable-number determination of salmonella levels in naturally contaminated raw almonds using two sample preparation methods
Pathogens occurring in particulate foods may be unevenly distributed; which may impact interpretation of most-probable-number (MPN) values. The MPN analysis of Salmonella in naturally contaminated raw almonds was conducted using two sample preparation methods. Raw almond kernels (3;698 samples) and inshell almonds (455 samples) were collected from almond processors throughout California during the 2006 and […]
Gasification of cashew nut shells for thermal application in local food processing factory.
Cashew nut shells are high energy content residues from cashew nut processing. It can potentially replace fuelwood for thermal application in a factory. However; direct combustion of cashew nut shells was troublesome due to low efficiency and high smoke emission. Alternative thermal conversion of cashew nut shells should be used instead. In this work; a […]
