1. Extraction and Characterization of Pequi Seed Oil for Biodiesel Production: A Green Management of Waste to Biofuel Using Ethanol and Heterogeneous Catalysis
This work reports the characterization of a vegetable oil extracted from pequi seeds, an agroindustrial residue, and its biodiesel production using ethanol and heterogeneous catalysis. The pequi seeds showed 40.73 wt.% of extractive content, which represents a large amount of the biomass composition. The crude oil extracted from the pequi seeds with ethanol

2. Chemical and antioxidant characterization, sensory and shelf-life analysis of cereal bars with almonds from pequi (Caryocar brasiliense Camb.)
Abstract The study aimed to know how almonds from Pequi (Caryocar brasiliense Camb.), a byproduct of this fruit from Brazilian Cerrado, can be used to improve value to cereal bars. To respond to this question, the study characterized pequi almonds and cereal bars with pequi, and evaluate sensory acceptance. The preparation of cereal bars enriched with pequi

3. FATTY ACIDS ANALYSIS AND CHEMOTAXONOMIC CONSIDERATIONS OF MALVOIDEAE (MALVACEAE) SPECIES
Previous researches showed that fatty acids analysis might be a useful tool to support the taxonomic investigation. In this approach the fatty acids content of ten Malvoideae species was analyzed and its chemotaxonomic significance has been investigated. The aerial parts of the species were collected in the Northeast of Brazil and their fatty acid methyl est

4. Odontadenia lutea (Apocynaceae) LEAVES: PHYTOCHEMICAL STUDY AND INSECTICIDAL ACTIVITY AGAINST LEAF-CUTTING ANTS Atta sexdens rubropilosa Forel
The present work describes the chemical constituents of Odontadenia lutea (Vell.) Markgr. leaves and the toxicities of its extract and fractions against Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae). Chromatographic procedures of the ethanolic extract resulted in the identification of the triterpene β-amyrin, the flavonoid rutin, two fatty acids

5. Analysis of the chemical properties of salted cobia (Rachycentron canadum)
Abstract Aquaculture of cobia (Rachycentron canadum) is still incipient in Brazil, as well as the sale of its meat. However, there is a market demand for this product in the state of Rio de Janeiro. The salting process for the meat of cultivated cobia is a way of preserving and marketing the product for the growers. Thus, the present study aimed to assess th

6. Physicochemical parameters and lactic acid bacteria count during ripening of Brazilian regional cheese manufactured with the addition of autochthonous cultures
Abstract The physicochemical analyses and quantification of lactic acid bacteria of cheeses made from autochthonous lactic cultures were evaluated during ripening. There was a decrease in water activity, pH and moisture, and an increase in acidity, total solids, proteolysis, lipids, fat in dry matter and ash. The major fatty acids identified were palmitic, o

7. Fatty acid and proteomic analysis of Sterculia striata nut
Abstract Chicha (Sterculia striata) is a native plant of the Cerrado biome that has only recently been explored nutritionally. The aim of this study was to determine its fatty acid profile and obtain the proteomic analysis of chicha nut. The nut was found to be composed of 22.19% protein, 20.62% lipids, 3.91% moisture, 3.63% ash, 53.56% carbohydrates, 19.99%

8. Potential of mangaba (Hancornia speciosa), mango (Mangifera indica L.), and papaya (Carica papaya L.) seeds as sources of bioactive compounds
ABSTRACT The bioactive compounds and the antioxidant capacities of mangaba, mango and papaya oils were investigated. Determinations of fatty acid composition, tocopherol, phytosterols, phenolic compounds profile, total carotenoids, and antioxidant activity were carried out in the oils of mangaba, mango and papaya seeds. The analysis of antioxidant activity w

10. Chemical, physicochemical, microbiological and sensory characterization of cow and buffalo ghee
Abstract Due to the increasing consumption of ghee in the Western countries, a complete characterization of buffalo and cow ghee was performed to complement and update the available literature. Ghee is a lipophilic dairy product with 98.9% lipids, 0.3% water and less than 0.9% nonfat solids. Fatty acids are the major lipid fraction and represent 85.1% and 83
