1. Development and Chemical Characterization of Pequi Pericarp Flour (Caryocar brasiliense Camb.) and Effect of in vitro Digestibility on the Bioaccessibility of Phenolic Compounds
The pequi pericarp corresponds to the largest portion of the fruit and has a high nutritional value, but it is discarded as an agro-industrial residue. The present study aimed to prepare and characterize flours from the pequi pericarp in terms of their proximate composition, its antioxidant potential before and after the in vitro digestibility process and ch

2. Obtaining and characterization of anthocyanins from Euterpe oleracea (açaí) dry extract for nutraceutical and food preparations
Abstract The main constituents of the Euterpe oleracea Mart., Arecaceae, fruits (açaí) are anthocyanins. This paper aimed to standardize the extraction process and characterize an anthocyanin-rich dry extract obtained from this fruit. A 23 full factorial design was used. The volumes of ethanol 92% and acetic acid and the extraction time were used as factor

3. Dithiocarbamate Residues in Fruits and Leaves of Passion Fruit (Passiflora edulis) from Different Brazilian Regions
Dithiocarbamates are widely used fungicides, including in passion fruit, whose fruits are mainly used for juice production, the leaves for the preparation of herbal tea and medicines. Also, the use of the peel in the food industry has been proposed. In this study, the spectrophotometric method for determination of dithiocarbamate residues, as CS2, in passion

5. Pyrethroid insecticide residue in ‘Grande Naine’ banana peel and pulp during maturation
Abstract In banana farming, the bagging of bunches with bags impregnated by pyrethroid insecticide is a practice that prevents damage to fruits caused by insect pests. The aim of this study was to monitor the presence and permanence of bifenthrin residue during the maturation of ‘Grande Naine’ banana by gas chromatography coupled to mass spectrometer in

6. Effects of Acmella oleracea methanolic extract and fractions on the tyrosinase enzyme
Abstract The aim of the current study is to evaluate the effect of Acmella oleracea (L.) R.K. Jansen, Asteraceae, methanolic extract, hexane (84.28% spilanthol) and dichloromethane (approximately 100% spilanthol) fractions on the tyrosinase enzyme. The dehydrated jambu extract was obtained through maceration using methanol. The extract residue was solubilize

10. Análise técnica, econômica e ambiental de macaúba e de pinhão-manso como alternativas de agregação de renda na cadeia produtiva de biodiesel / Technical, environmental, and economic analysis of oil palm and physic nut as an alternative for adding income in the productive chain of biodiesel
With concentration increasing of gases in the atmosphere the greenhouse effect is getting worse and causing the global warming, mainly from burning fossil fuels that has been observed since the Industrial Revolution. It is clear who anthropogenic actions were increasing emissions of greenhouse gases (GHG) and endangers the earth environmental sustainability.
