1. The Catalytic Action of Copper Ions and the Rosemary Extract Antioxidant Effect in the Biodiesel Oxidation Reaction and the Implication in Arrhenius Behavior
Biodiesel contains esters in its composition which make it susceptible to oxidation. Among the factors that cause this reaction is the contamination with metal ions. In the present work, it was analyzed biodiesel samples obtained from a mixture containing 39.0% m/m soybean oil, 22.0% m/m beef tallow and 39.0% m/m poultry fat using a methyl route. Copper ions

2. Lipid Sources in Diets for Hy-Line White Laying: Performance, Biometrics of Digestive Organs, and Bone Characteristics
ABSTRACT Dietary inclusion of lipid sources has been one of the methods adopted by nutritionists aiming at better energy balancing. However, alternative energy feedstuffs have been sought in an attempt to reduce production costs. In this regard, lipid sources that can replace conventional ones, such as beef tallow, cottonseed oil, and sunflower oil have been

3. BEEF TALLOW AND EMULSIFIER IN GROWING-FINISHING PIG DIETS
ABSTRACT Two trials were aimed to evaluate beef tallow in diets with and without emulsifier on performance of pigs at growing-finishing phases. In the first trial, 15 barrows (22.03±0.62 kg) were distributed among three treatments: reference diet; test diet 1 (5% beef tallow) and test diet 2 (10% beef tallow). Beef tallow presented average value of 7130.97

5. Evaluation of the oxidative stability of biodiesel blends from soybean, tallow and castor bean using experimental mixture design
Nesse estudo um planejamento experimental de misturas de biodieseis é utilizado para avaliar e otimizar a estabilidade oxidativa de amostras de biodiesel de soja contendo diferentes teores de biodiesel de sebo e de mamona. As misturas de biodieseis foram preparadas com teores que variaram entre 80-86% (v/v) para a soja, 5-15% (v/v) para o sebo e 1-10% (v/v)

6. Obtenção de biodiesel por transesterificação em dois estágios e sua caracterização por cromatografia gasosa: óleos e gorduras em laboratório de química orgânica
Methanolic transesterification of oils and fats was carried out in a two steps procedure, under basic and acidic catalysis. Palm, soybean, canola, corn, rice, grapeseed, sunflower, peanut, pequi and olive oils, besides tallow and lard were used as feedstock. Specific gravity, relative viscosity, thin layer chromatography and gas chromatography were used to c

7. Estudo da influência da adição de etanol e/ou metanol ao biodiesel associado a ferramentas quimiométricas
The objective of this work is to study the influence of the addition of alcohol methanol or ethanol - to biodiesel. Therefore, Principal Components Analysis (PCA) was combined with infrared spectra with the aim of separating soybean and tallow biodiesel samples with different alcohol contents of ethanol or methanol. PCA yielded a good reduction of data regar

8. Uso do óleo de soja e sebo bovino sobre a digestibiblidade da dieta, perfil bioquímico e consistência fecal de cães adultos / Use of soybean oil and beef tallow on diet digestibility, biochemical profile and faecal consistency of adult dog
Em dietas de melhor qualidade e maior densidade energética para cães, o acréscimo de altos níveis de gordura é fundamental. A gordura na dieta traz uma série de benefícios, como sua alta digestibilidade aparente (85 ¿ 95%) e fornecimento de ácidos graxos essenciais. Os triglicerídeos são o tipo de gordura mais importante da dieta e dependendo do t

9. SIMULTANEOUS DETERMINATION OF FREE AND TOTAL GLYCEROL, MONO-, DI- AND TRIGLYCERIDES IN ETHYLIC BIODIESEL OF SUNFLOWER, CASTOR OIL AND TALLOW/SOYBEAN MIXTURE USING GC-FID / DETERMINAÇÃO SIMULTÂNEA DE GLICEROL LIVRE E TOTAL, MONO-, DI- E TRIGLICERÍDEOS EM BIODIESEL ETÍLICO DE GIRASSOL, MAMONA E DA MISTURA DE SEBO E SOJA EMPREGANDO GC-FID
The biodiesel produced to be marketed in Brazil should be according to the quality standards established by the Resolution of February 4, 2010 of the Agência Nacional do Petróleo, Gás Natural e do Biocombustível (ANP, 04/2010). In this work, the application of the methods ASTM D 6584 e EN 14105 for castor oil biodiesel and biodiesel from ethylic routes w

11. Soybean Oil and Beef Tallow in Starter Broiler Diets
The objective of this study was to determine the energy values of soybean oil (SBO) and tallow (T) combined in different ratios, and to evaluate their effects on the performance, body composition, and serum lipid levels of starter broilers. In experiment I, a digestibility trial was performed to determine the energy value of the SOB and T mixtures using 100
