Industrial by-products are produced every day through fruit processing industries. Pineapple is not an exception; when processed, around 60% (w/w) of its weight peels, stem, trimmings, and crown, the only used part for human consumption. Due to high concerns sustainability in food system negative impact practice environment, a strategy has be developed. Therefore, green chemistry approach was applied pineapple make integrated valorization by extraction bioactive molecules. Two (peels stems)...
This work aimed to evaluate the digestive stability of peptides previously identified from a Corolase PP soy protein hydrolysate (SPH) and respond uncertainty about merit controlled hydrolysis. For this purpose, we applied an empirical theoretical analysis, determining peptide sequences, oxygen radical scavenging (ORAC) ACE inhibitory (iACE) activities, effect hydrolysis on solubility. Results showed that during digestion most SPH were degraded as smaller ones. However, both bioactivities...
Illustration of the final product solid carnauba nanoparticles loaded with rosmarinic acid in dried state suitable for food incorporation.
Liquid-enriched fraction (LOPP) from the by-product olive pomace is a powder with great potential as source of bioactive compounds.
Solid fractions from pineapple stems and peels are constituted by structural carbohydrates coupled with dietary fibre, simple sugars, but also vitamins polyphenols, which together can have potential effects on human health. The present studies report for the first time bioavailability bioaccessibility of by-products throughout simulated gastrointestinal tract, evaluates prebiotic in vitro microbiota fermentation. flours promoted faeces fermentation through growth beneficial strains, being...
Abstract: Rosmarinic acid (RA) possesses several protective bioactivities that have attracted increasing interest by nutraceutical/pharmaceutical industries. Considering the reduced bioavailability after oral use, effective (and safe) delivery systems are crucial to protect RA from gastrointestinal degradation. This study aims characterize safety profile of solid lipid nanoparticles produced with Witepsol and Carnauba waxes loaded RA, using in vitro vivo approaches, focused on genotoxicity...
Recent studies indicate that plant polyphenols could be pointed as potential prebiotic candidates since they may interact with the gut microbiota, stimulating its growth and production of metabolites. However, little is known about fate brown seaweeds' phlorotannins during their passage throughout gastrointestinal tract. This work aimed to evaluate stability bioaccessibility
Pineapple peel still contains an important amount of phenolic compounds and vitamins with valuable antioxidant activity. In this way, the aim study was recovery bioactive from pineapple using environmentally friendly low-cost techniques, envisaging their application in food products. From solid-liquid extraction conditions tested, one delivering extract higher total content capacity a single step solvent-pineapple ratio 1:1 (w/w) for 25 min at ambient temperature, ethanol-water (80–20%) as...
Synthetic vitamin E is commonly used in aquafeeds to prevent oxidative stress fish and delay feed flesh oxidation during storage, but consumers' preferences tend towards natural antioxidant sources. The potential of vegetable antioxidants-rich coproducts, dried tomato (TO), carrot (CA) coriander (CO) was compared that synthetic included diets at either a regular (CTRL; 100 mg kg-1) or reinforced dose (VITE; 500 kg-1). Natural antioxidants were added 2% the CTRL. Mixes then extruded dried,...
Tomato by-products from processing industries have a higher potential to be reused as source of bioactive compounds. Reliable national data on tomato and physicochemical characterisation that will inform find effective planning waste management in Portugal is absent. To help obtain this knowledge, selected companies were recruited representative samples generation, composition was evaluated. Furthermore, an environmental-friendly method (the ohmic heating (OH) method, which allows the...
Currently, there is special interest in the recovery of polyphenols from non-compliant fruits that have no market value; efforts to find value-added solutions for these food areas are a key option sustainable bio-economy. Saco cherries traditional Portuguese cherry variety, and although they nutritionally important food, rich powerful dietary polyphenols, significant amounts not sold due their small size. In this context, work aimed select best method produce novel antioxidant...
