15. Characterization of a hydrolyzed oil obtained from fish waste for nutraceutical application
The fish industry generates high volume of waste from fish oil that can have the extraction of its lipids used as nutraceuticals and foods. The objective of this study was to produce unsaturated fatty acids from industrialized fish oil by means of a differentiated hydrolysis process. The samples used were crude fish oil obtained from Campestre industry and c

16. Extraction and characterization of lipids from Sarcocornia ambigua meal: a halophyte biomass produced with shrimp farm effluent irrigation
Sarcocornia ambigua é uma planta herbácea perene, nativa da América do Sul e uma nova oleaginosa com potencial para forrageira, cultivada por irrigação direta com água salgada. Suas pequenas sementes se desenvolvem dentro dos segmentos do seu caule cilíndrico sem folhas e, durante a colheita, as sementes se misturam com o material celulósico remanesc

17. Comparison of two lipid extraction methods produced by yeast in cheese whey
This work aimed to evaluate nine strains of yeast, previously identified as good producers of lipids in honey medium, for selecting the most suitable strain for the production of lipids in cheese whey medium and compared two well known extraction methods of lipids from the culture medium. The highest yield of total lipids was 1.27 g.L-1 produced by Cryptococ

18. Impact of different extraction methods on the quality of Dipteryx alata extracts
This study aimed to impact of different extraction methods on the quality of Dipteryx alata Vogel, Fabaceae, extracts from fruits. The major compounds found were the lipids 38.9% (w/w) and proteins 26.20% (w/w). The residual moisture was 7.20% (w/w), total fiber 14.50% (w/w), minerals 4.10% (w/w) and carbohydrate 9.10 % (w/w). The species studied has great p

19. Ação antioxidante de extratos de especiarias e suas misturas binárias e ternárias sobre a estabilidade oxidativa de óleo de soja / Antioxidant activity of spices extracts and their binary and ternary mixtures on soybean oil oxidative stability
The lipid oxidation produces undesirable compounds that alter the organoleptic characteristics of food lipids and reduce the nutritional quality. In the food, cosmetics and pharmaceutical industries, synthetic antioxidants are added to retard or prevent the lipid deterioration. Due to the possible toxicity of synthetic antioxidants and the call for active na

20. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO ANALÍTICO POR DISPERSÃO DA MATRIZ EM FASE SÓLIDA E CROMATOGRAFIA EM FASE GASOSA ACOPLADA A ESPECTROMETRIA DE MASSAS PARA DETERMINAÇÃO DE PESTICIDAS EM AMOSTRAS DE OVOS DE GALINHA (GALLUS GALLUS DOMESTICUS). / DEVELOPMENT AND VALIDATION OF ANALYTICAL METHOD FOR SCATTERING MATRIX SOLID PHASE AND GAS CHROMATOGRAPHY COUPLED TO A MASS SPECTROMETRY DETERMINATION OF PESTICIDES IN SAMPLES OF CHICKEN EGGS (GALLUS GALLUS DOMESTICUS).
The eggs are of great nutritional value. Its biochemical composition indicates the source of proteins, lipids, vitamins and minerals. However, undesirable chemical compounds can form part of this constitution. The pesticides, when applied irregularly, can represent a serious health risk to consumers if detected above the maximum residue limits, can be identi
