16. Bioactive compounds and value-added applications of cupuassu (Theobroma grandiflorum Schum.) agroindustrial by-product
Abstract Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to the multiple uses of its pulp and seeds in the food and cosmetic industries. This fruit generates large amounts of solid waste, which, despite of its high content of bioactive compounds, is discarded in the environment. Therefore, with the aim of reusing the

17. Liquid-liquid equilibria in aqueous two-phase ethanol/salt systems at different temperatures and their application to anthocyanins extraction
Abstract Aqueous two-phase systems (ATPS) are formed by mixtures of chemical species that, under certain conditions, separate into two immiscible phases, with water as the major component in global terms and, at lower concentrations, polymers, salts, ionic liquids and alcohols, depending on the system type. Different parameters influence ATPS equilibrium suc

18. Optimization of ultrasound-assisted extraction of bioactive compounds from jabuticaba (Myrciaria cauliflora) fruit through a Box-Behnken experimental design
Abstract Jabuticaba is a very popular fruit in Brazil being a great source of compounds with considerable biological activities. Novel optimized ultrasound-assisted extraction (UAE) methods have been proposed for anthocyanins and total phenolic compounds from jabuticaba. A Box–Behnken experimental design (BBD) with a response surface methodology (RSM) was

19. Mineral and centesimal contents, antioxidant activity and antimicrobial action of phenolic compounds from Eugenia Brasiliensis Lam. Pulp
Abstract Phenolic compounds (PC) have presented antioxidant potential as well as antimicrobial action against several bacteria. This study aimed to extract PC from grumixama (Eugenia brasiliensis Lam.) pulp using solid phase extraction (SPE), then quantify the PC by Folin-Ciocalteu assay, and to evaluate the antioxidant activity (AA) from PC by DPPH, ABTS a

20. Orange and Passion Fruit Wastes Characterization, Substrate Hydrolysis and Cell Growth of Cupriavidus necator, as Proposal to Converting of Residues in High Value Added Product
Abstract: Brazil is the world’s largest producer of orange and passion fruit, which are destined mainly for industrialization, generating grand volumes of wastes. The solid portion of these residues is a rich source of pectin - composed mainly of galacturonic acid and neutral sugars, which through the hydrolysis process can be used in biological conversion

21. Population Structure and Fruit Productivity Analyses in Support of the Use of Caryocar brasiliense
ABSTRACT The Brazilian Cerrado, a global biodiversity hotspot, has been widely converted by agricultural expansion and pasture establishment. As a result of these activities, several plant species have experienced population declines such as pequi (Caryocar brasiliense ). We analyzed the feasibility of economic use of C. brasiliense based on population stru

22. Evaluation of the Influence of Extraction Conditions on the Isolation and Identification of Volatile Compounds from Cagaita (Eugenia dysenterica) Using HS-SPME/GC-MS
The objective of this study was to explore the extraction and identification of volatile organic compounds (VOCs) present in cagaita fruit (Eugenia dysenterica). Parameters such as type of extraction fiber, agitation, extraction time and extraction temperature were investigated. Initially, the VOCs were extracted using headspace solid-phase microextraction.

23. SPME Fiber Evaluation for Volatile Organic Compounds Extraction from Acerola
Volatile organic compounds (VOCs) were isolated from acerola fruits (Malpighia emarginata D.C.), by means of different solid phase microextraction (SPME) fibers. For the extraction, the headspace SPME method was used, identifying the VOCs by gas chromatography (GC) with mass spectrometry (MS). The objective of this work was to evaluate the efficiency of SPME

24. 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
