25. Estudo do efeito da adição de gorduras alternativas na cristalização da manteiga de cacau / Influence of the addition of alternative fats on cocoa butter crystallization
A influência da incorporação de gorduras alternativas low e zero trans na cristalização da manteiga de cacau foi avaliada através da caracterização física de misturas binárias de manteiga de cacau com gordura de cupuaçu, gordura CBR low trans e gordura CBS, nas proporções de 5, 10, 15, 20, 25 e 30 %. O processo de pré-cristalização (temperage

26. Titulação potenciométrica aplicada na determinação de ácidos graxos livres de óleos e gorduras comestíveis
Free fatty acids are a measure of evaluating fats and oils, submitted to abusive conditions, besides being a quality characteristic of edible vegetable oils. The official method of determination (AOCS Ca 5a-40, 2004) is based on titration, using phenolphthalein as an indicator. For crude and degummed oils, the titration end point is difficult to be observed

27. PRODUÇÃO DE JUNDIÁ (Rhamdia quelen) ALIMENTADOS COM DIETAS CONTENDO ÓLEOS DE ARROZ, CANOLA OU SOJA / PRODUCTION OF JUNDIÁ (Rhamdia quelen) FED WITH DIETS CONTAINING RICE, CANOLA OR SOY OIL
This work had for objectives to evaluate the influence of vegetable oils in the corporal development of jundiá (Rhamdia quelen, Heptapteridae) and its relationship with the quality of the fish. Six diets were tested with 32% of crude protein and rice, canola or soy oil at 5 or 10% inclusion, for 90 days. Fish (180, initial weigh=710,8g) were distributed at

28. In vitro anti-Candida activity and chemical investigation of leaves and bulbs of Allium tuberosum Rotth. ex Sprengel / Estudo quimico do Allium tuberosum Rottl. ex Spreng biomonitorado pela avaliação da atividade anti-Candida albicans
Frequently used in folk medicine, the genus Allium include more than 600 species founded in several world regions like Europe, North America, Africa and Asia. The most of species is edible and have a aroma and smell characteristics, being algo used as hypocholesterolemic, anticold and antimicrobial. Among theAllium species,A. tuberosum Rottl. ex Spreng (Lili

29. Síntese de lipídios estruturados por interesterificação de gordura de frango e triacilgliceróis de cadeia média / Synthesis of structured lipids from interesterification reaction of chicken fat and medium chain triacylglycerols
Structured triacylglycerols are generally any fats that are modified or restructured from natural oils and fats, or fatty acids therefrom, having special functionality or nutritional properties for edible or pharmaceutical purposes. These restructured triacylglycerols are synthesized by blending and chemical or enzymatic interesterification reaction of oils

30. Recuperação de acidos graxos livres em resina de troca ionica. / Recuperation of free fatty acids in ion exchange resins.
The drastic operational conditions used in the chemical or physical refining of edible oils can in some cases lead to losses of nutraceutical compounds, high losses of neutral oil or even to the darkening of the end product. Liquid-liquid extration can be used as an alternative refining process, since mild operation conditions are employed in this case. But

31. Reproductive and productive performance of lactating sows fed diets supplemented with vegetable oil or tallow / Efeito da adição do óleo de soja, óleo de linhaça, óleo de coco babaçu e sebo bovino nos parâmetros produtivos e reprodutivos de fêmeas suínas em lactação
Twenty-four Dalland C40 sows were used in one experiment to study the effect of dietary vegetable oil or tallow on productive and reproductive parameters. All sows were fed a corn-soybean meal diet supplemented with 8% soybean (T1), linseed (T2), coconut (T3) oil or tallow (T4) from day 100 of gestation and throughout the lactation period. Sow initial weight

32. Desacidification of the oil of bran of rice for extration liquid-liquid. / Desacidificação do oleo de farelo de arroz por extração liquido-liquido.
The objective of this work was to evaluate the rice bran oil deacidification process by liquid-liquid extraction (LLE), in a continuous equipment, using aqueous ethanol as solvent. The alternative process was evaluated in terms of: ability to extract the free fatty acids; ability to minimize the neutral oil loss and, ability to preserve nutraceutical compoun

33. Biosynthesis of Very-Long-Chain Polyunsaturated Fatty Acids in Transgenic Oilseeds: Constraints on Their AccumulationW⃞
ω6- and ω3-polyunsaturated C20 fatty acids represent important components of the human diet. A more regular consumption and an accordingly sustainable source of these compounds are highly desirable. In contrast with the very high levels to which industrial fatty acids have to be enriched in plant oils for competitive use as chemical feedstocks, much lower

34. Developmental and growth temperature regulation of two different microsomal omega-6 desaturase genes in soybeans.
The polyunsaturated fatty acid content is one of the major factors influencing the quality of vegetable oils. Edible oils rich in monounsaturated fatty acid provide improved oil stability, flavor, and nutrition for human and animal consumption. In plants, the microsomal omega-6 desaturase-catalyzed pathway is the primary route of production of polyunsaturate

35. A jojoba beta-Ketoacyl-CoA synthase cDNA complements the canola fatty acid elongation mutation in transgenic plants.
beta-Ketoacyl-coenzyme A (CoA) synthase (KCS) catalyzes the condensation of malonyl-CoA with long-chain acyl-CoA. This reaction is the initial step of the microsomal fatty acyl-CoA elongation pathway responsible for formation of very long chain fatty acids (VLCFAs, or fatty acids with chain lengths > 18 carbons). Manipulation of this pathway is significant f
