The release of secretin and somatostatin by liquid meals with different fatty-acid composition was investigated in humans. For this purpose, plasma secretin and somatostatin concentrations were measured in two groups of cholecystectomized subjects, before and after the ingestion of a meal that contained sunflower oil (Group A) or equicaloric amounts of sunflower oil, olive oil and cream (Group ...

Vegetable protein meals are heated during processing to remove antinutritional factors. For example, soybean meal contains protease inhibitors that reduce protein digestibility, lectins that cause lesions in the gut wall and goitrogens that influence the function of thyroxin. Canola meal can contain glucosinolates, which along with the enzyme myrosinase can produce compounds that irritate the g...

Ethanol and biodiesel production have become important industries worldwide. For example, ethanol production in the United States has increased exponentially from 6.0 billion liters in 2000 to 49 billion liters in 2010, an increase of 800% (RFA, 2011). Similarly, biodiesel production increased in the U.S. from 424 million liters in 2005 to 1,191 million liters in 2010 (NBB, 2011). These booming...

BACKGROUND The incidence of ischemic heart disease (IHD) in Crete was lower than expected on the basis of blood lipid concentrations of participants in the Seven Countries Study. A favorable effect of a high intake of olive oil on thrombogenesis may have contributed to this finding. OBJECTIVE We compared the effects of virgin olive oil with those of rapeseed and sunflower oils on blood coagul...

BACKGROUND The triacylglycerol structure of saturated fats may influence postprandial lipemia. OBJECTIVE We tested the hypothesis that high-fat meals rich in palmitic acid (16:0) in the sn-2 position decrease lipemia. DESIGN Postprandial changes in plasma lipids, apolipoprotein B48, and cytokines were compared in healthy men (n = 25) and women (n = 25) by using a randomized crossover design...

This study was conducted to produce biodiesel from a mixture of 5 different oils i.e, palm oil, used cooking soybean canola and sunflower through transesterification under mole ratio variations oil: methanol. The were mixed at total volume 300 mL with the same amount each oil used. blended 60°C for 1 h, ratios methanol set 1:3, 1:6, 1:9, 1:12, 1:15. results demonstrated that 1:6 resulted in hig...

This study was performed to examine the postprandial effects of meals containing dietary fats, with their natural fatty acid composition and tocopherol content, on the plasma triacylglycerols (TG) and tocopherols and on the resistance of VLDL and LDL to oxidation. On six separate days eighteen healthy male subjects were given low-fat meals (LF) or the LF meals enriched with sunflower oil (SO), ...

Background and Objectives: Oils used in frying should include special characteristics such as high oxidative stability, prolonged shelf life, low price, abundance and availability and desirable flavors. Nowadays, consumers are further interested in low saturated frying oils.  Recently, manufacturers focus on eliminating palm oil derivatives (as a major vegetable source of saturation) from fryin...
