Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do...

The safety and shelf-life of food products can be, respectively, ensured and extended with important food-processing technologies such as irradiation. The joint effect of cooking and 10 kGy gamma irradiation on the fatty acid composition of the oil of Pentaclethra macrophylla Benth was evaluated. Oils from the raw seed, cooked seeds, irradiated seeds (10 kGy), cooked, and irradiated seeds (10 k...

Recently, medium-chain triglycerides (MCTs) containing a large fraction of lauric acid (LA) (C12)-about 30%-have been introduced commercially for use in salad oils and in cooking applications. As compared to the long-chain fatty acids found in other cooking oils, the medium-chain fats in MCTs are far less likely to be stored in adipose tissue, do not give rise to 'ectopic fat' metabolites that ...

OBJECTIVE To examine the socio-economic and lifestyle determinants of cooking oil choice in Costa Rica during the last decade (1994-2004). DESIGN Cross-sectional study. Subjects (total n = 2274) belonged to the control population of a large case-control study; they were recruited yearly. Data about type of oil used for cooking, dietary intake, socio-economic and demographic characteristics we...

Medium-chain fatty acids (MCFA) have attracted attention as part of a healthy diet, because they are absorbed and transported directly into the liver via the portal vein, metabolized rapidly by beta-oxidation, and increase diet-induced thermogenesis. Because medium-chain triacylglycerols (MCT) containing only MCFA has a few weak points as frying oils, we have developed medium- and long-chain tr...

The chemical properties of oil from arils of both ripe and unripe ackee (Blighia sapida) were evaluated with a view to investigating the variations in their domestic and industrial applications. The chemical analyses of ripe and unripe aril oils respectively in different locations showed the percentage yield of oil from 54.91±2.75 to 78.25±3.91; 37.78±1.51 to 54.61 ± 2.18, iodine values of 90.0...

Thermal stressing of polyunsaturated fatty acid (PUFA)rich culinary oils according to routine frying or cooking practices generates high levels of cytotoxic aldehydic products (predominantly trans -2-alkenals, trans , trans -alka-2,4dienals, cis , trans -alka-2,4-dienals, and n -alkanals), species arising from the fragmentation of conjugated hydroperoxydiene precursors. In this investigation we...

Biodiesel is usually produced from food-grade vegetable oils that are more expensive than diesel fuel. Therefore, biodiesel produced from food-grade vegetable oil is currently not economically feasible. Waste cooking oils, restaurant grease and animal fats are potential feedstocks for biodiesel. These inexpensive feedstocks represent one-third of the US total fats and oil production, but are cu...
