“…The extractive process is an essential step in the recovery and purification of bioactive compounds (such as phenolic compounds) from plant matrices [33]. The extraction efficiency depends on several parameters, such as temperature, time, solvent polarity, pH, among others [34]. The RSM is a useful statistical toll for assessing the effect and interaction of many of these variables and finding the variables combinations that will produce the optimal response [35].…”

Chestnut processing industry generates large amounts of by-products, including leaves, burs and shells that are a source of bioactive compounds. The purpose of this study was to establish an ultrasound-assisted extraction (UAE) of phenolic and antioxidant compounds from industrial chestnut shells. A central composite design (CCD) was conducted to analyze the effects of time (4–46 min) and temperature (34–76 °C) in the antioxidant activity (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP)) and total phenolic compounds (TPC) of chestnut shells extracts. The optimal extraction conditions were obtained at 70 °C for 40 min. The optimal extract was characterized regarding phenolic profile, radical scavenging capacity, and effects on intestinal and dermal cell lines. The optimal extract revealed high amounts of ellagic acid (40.4 µg/mg dw), followed by caffeic acid derivative (15.4 µg/mg dw) and epigallocatechin (15.3 µg/mg dw). Indeed, the extract exhibited the highest scavenging efficiencies against NO● (IC50 = 0.1 µg/mL) and HOCl (IC50 = 0.7 µg/mL) and did not conducted to a decrease on HaCaT and HFF-1 viability up to 100 μg/mL. Oppositely, a decrease on Caco-2 and HT29-MTX viability was observed. This study suggests that UAE could be a sustainable option to valorize chestnut shells as raw material for different industries.

“…Those processes, present as major disadvantages high energy consumption, as well as the use of high temperatures which may degrade some phenolic compounds.Concentration by nanofiltration of bioactive compounds extracted from natural products, such as orange press liquor (Conidi et al, 2012), pequi (Caryocar brasilense Camb.) (Machado et al, 2013), aqueous mate (Negrão Murakami et al, 2011), bark from mate tree (Prudêncio et al, 2012) or propolis (Mello et al, 2010;Tylkowski et al, 2010) has been successfully employed. Unlike traditional concentration methods, the use of membrane separation processes has increased, due to certain advantages, such as the non utilization of organic solvents or other chemicals for the concentration process, high recovery efficiency, absence of phase transition, low operation temperatures and low energy consumption (Conidi et al, 2012;Matta et al, 2004).…”

“…Phenolic compounds are the most abundant secondary metabolites present in mate, which are primarily caffeoyl derivatives (3,5‐dicaffeoylquinic, 4,5‐dicaffeoylquinic, 3,4‐dicaffeoylquinic, and chlorogenic acids) and flavonoids (rutin, quercetin, kaempferol, and luteolin). Some of the biological properties of aqueous mate extract, including its antioxidant and antimicrobial properties, are attributed to the presence of these compounds …”

Active packaging can be defined as packaging that includes additives that help to extend the shelf life of food; among the advantages of its use is the possibility to reduce the amount of additives added to the food during processing. The aim of this study was to develop, characterize, and apply active films of low‐density polyethylene, incorporating carotenoid and yerba mate extracts as active additives. Active films were obtained by extrusion and were characterized for water vapor permeability, thickness, color, and mechanical and thermal properties. The effectiveness of the films was evaluated using butter packed in the formulated films. There was a significant reduction in thickness, and mechanical, thermal, and water vapor barrier parameters of the films compared to the control. The concentration of additives directly influenced coloration and antioxidant and antimicrobial action of the films. The formulated films provided protection against oxidative action and inhibition of microbial growth. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46461.
