Edible seeds, especially those known by the population as nuts, have their consumption associated with functional appeal. The present study aimed to compare and group nine different seeds, traditional and regional, according to their similarities, in terms of moisture, total phenolic compounds (TPC) and antioxidant activity, through multivariate an...

Poly (vinyl alcohol) (PVA) nanofibers (FWater) and enriched with aqueous extracts of acai pulp (FAP), cocoa shell (FCS), jabuticaba peels (FJP) and carrot residue (FCR) were produced by solution blow spinning (SBS) and applied to strawberries. Nanofibers presented uniform morphology with diameters between 352 (FWater) and 504 (FJP) nm, high TPC con...

Immiscible and not fully miscible polymers are difficult to process into nanofibers. Nanofibers production techniques, such as solution blow spinning (SBS), come as alternatives to produce materials from PVA and zein. In this study, PVA/zein nanofibers were produced with the solution blow spinning (SBS) technique, while using an aqueous solution of...

Among the fruit species found in the Cerrado biome of Brazil, Campomanesia pubescens stands out. It produces fruits with a sweet and sour taste, known as gabiroba, which are consumed fresh or processed. This study aimed to evaluate Campomanesia pubescens fruits from Campos das Vertentes – MG, Brazil, regarding their phenological and physicochemical...

The aim of this study was to produce nanostructured poly (lactic acid) (PLA) mats incorporated with the 1-MCP/α-CD complex (F1-MCP) by the solution blow spinning (SBS) technique and to apply them as a nano-sachet emitting 1-MCP in a banana packaging system. The nanofibers that comprise the mats presented uniform morphology with diameters between 15...

The development of a seed coating with micronutrient release system is of extreme research importance for sustainable agriculture. In this work, a zinc release system was developed, using zinc-loaded PVA/Zein nanofibers. Solution blow spinning was used to produce nanofibers (average diameter of approximately 160 nm), as demonstrated by field-emissi...

Esta pesquisa teve como objetivo avaliar a capacidade antioxidante total do extrato comercial de Casearia sylvestris. Dois métodos diferentes (Folin-Ciocalteau e Fast Blue) foram usados para quantificar o teor de compostos fenólicos totais. Os ensaios ABTS+, Betacaroteno/Ácido Linoleico, Complexo de Fosfomolibdênio, DPPH- e FRAP foram utilizados pa...

The green synthesis of silver nanoparticles offers a non-toxic, eco-friendly, economical, and efficient solution against various microorganisms. The study aimed to investigate the utilization of cocoa bean shells for the production of silver nanoparticles through green synthesis, besides its characterization and evaluation against foodborne pathoge...

The purple passion fruit (Passiflora edulis Sims) is a fruit that has an intense and wrinkled purple peel when ripe. In the food industry, the passion fruit pulp is used in the production of juices and nectars, while the peel and seeds are considered waste, although they have great biotechnological potential due to their chemical composition , with...

In recent years, minimally processed fruits and vegetables have gained widespread consumer attention due to the need for a convenient yet healthy diet. As several factors can affect the shelf life of minimally processed products, it is essential to use preservation technologies that maintain the freshness of fruits and vegetables ensuring consumer...

The objective was to optimize the phenolic compounds extraction from cocoa shells using the simplex-centroid design with a mixture of solvents (water, methanol, and acetone) as its components, to prove the presence of these compounds and antioxidant activity. Also, the development of dairy products, such as milk beverages and dairy desserts, with b...

The objective of this study was to develop biodegradable films produced from broken grains of rice (agro-in- dustrial byproducts), sorbitol, and pectin, and to evaluate the influence of pine (PN), eucalyptus (EN), and corn straw (CN) nanofibers on the opacity, solubility, water vapor permeability, mechanical properties, and morphology of the films....

The objective of this study was to develop biodegradable films produced from broken grains of rice (agro-industrial byproducts), sorbitol, and pectin, and to evaluate the influence of pine (PN), eucalyptus (EN), and corn straw (CN) nanofibers on the opacity, solubility, water vapor permeability, mechanical properties, and morphology of the films. T...

The Brazilian cerrado is the biome with the greatest biodiversity in the world and fruit species-rich in bioactive compounds. Chemometric techniques can potentially group alternatives from natural sources of bioactive compounds reliably and intuitively. Thus, in the present study, the objective was to analyze fruits of 13 cerrado species for the pr...

Pitanga fruit stands out for its exotic flavour and antioxidant properties. The objective of this work was to evaluate changes in the physical, chemical and biochemical variables of red pitanga variety, in four stages of development (green, yellow, orange and red) and associate them to the cell wall break down. Analysis of pH, titratable acidity, s...
