Evaluation of the potential of annatto seed powder to reduce the formation of h...
Neves-Gonçalves, TD; Pinto, E; Viegas, Olga; Braga, ARC; Mesquita, LMD; Ferreira, IMPLVO; García-Jares, C; De Rosso, VV; Domene, SMAVarious strategies are being explored to reduce the formation of undesirable compounds during the thermal processing of foods. This study investigates the impact of incorporating annatto seed powder (Bixa orellana L.) into beef patties to reduce the formation of heterocyclic amines (HAs) during charcoal-grilling and pan-frying. A three-level full factorial design was used to assess the effect of both annatto se...
Effects of preharvest lighting conditions on phenolic compounds and colour of r...
Silva, M; Moreno, DA; Domínguez-Perles, R; Viegas, Olga; Faria, M; Carvalho, SMP; Ferreira, IMPLVOThis study examined how lighting conditions (White, or a combination of Red + Blue LEDs; and supplemental UV-C: 0, 1 or 3 applications) and cultivars (Daikon, Red Rambo) affected the colour, total phenolics content, antioxidant activity and individual polyphenols of radish microgreens (Raphanus sativus L.) in a sustainable vertical farming system, as well as the implications for polyphenolic intake, connecting ...
Digestion of organosulfur compounds of two radish microgreen cultivars grown un...
Silva, M; Dominguez-Perles, R; Moreno, DA; Viegas, Olga; Faria, MA; Carvalho, SMP; Ferreira, IMPLVORadishes are rich in health-promoting organosulfur compounds. This study investigated the effects of gastrointestinal digestion (GID) on glucosinolates (GSLs) and isothiocyanates (ITCs) of two radish microgreens cultivars (Raphanus sativus; cv. Daikon, and cv. Red Rambo) grown in a closed vertical system under either White (W) or Red+Blue (R + B) LEDs, combined with varying applications of UV-C radiation (0, 1,...
Hormetic effect of UV-C radiation on red mustard microgreens growth and chemica...
Silva, M; Machado, J; López-Ruiz, R; Marín-Sáez, J; Viegas, Olga; Faria, M; Romero-Gonzalez, R; Garrido-Frenich, A; Carvalho, SMP; Ferreira, IMPLVOBrassica microgreens are rich in phytochemicals and are attractive crops for controlled vertical farming systems where the light spectrum can be precisely manipulated. Understanding the effects of pre-harvest hormetic UV-C light doses on plant composition and growth parameters represents a novel and largely unexplored area for precision agriculture and nutrition. Therefore, the objective of this work was to inv...
Exposure Scenarios for Estimating Contaminant Levels in Healthy Sustainable Die...
Ramos, H; Reis-Mendes, A; Silva, M; Ribeiro, M; Araújo, AM; Borges, C; Viegas, Olga; Melo, A; Martins, Z; Faria, MA; Ferreira, IMPLVO<jats:p>Consumers are regularly exposed to well-known food contaminants (FCs), which are typically assessed for risk on an individual basis. However, there is limited knowledge about the overall levels and combinations of these compounds depending on dietary choices. The goal of this study was to estimate the real-life mixtures of FCs in different dietary models by integrating extensive data from the scientific...
In vitro strategies to understand the impact of oral intake on the bioavailabil...
Ribeiro-Oliveira, R; Diniz, C; Ferreira, IMPLVOBioactive peptides from brewer's spent grain (BSG) and brewer's spent yeast (BSY), two by-products of the brewing industry, have great potential as functional food ingredients, dietary supplements or nutraceuticals to reduce the risk of numerous pathological conditions. Nevertheless, the oral administration of these peptides poses great challenges since peptides must undergo gastrointestinal digestion, intestin...
Bioactive Properties and Phenolic Composition of Wood-Aged Beers: Influence of ...
Machado, JC; Nicola, PDM; Viegas, Olga; Santos, MC; Faria, MA; Ferreira, IMPLVOAgeing beer in contact with wood is a common technological procedure that has been used for centuries to improve colour, structure, and certain flavours. Herein, the impact of the addition of French and American oak wood to two beer styles, pale and dark, on beer phenolic composition (total phenolics, total flavonoids, and HPLC-DAD) and bioactivity (FRAP, DPPH, anti-inflammatory activity in RAW 264.7, and antip...
Investigating the Impact of Dietary Fibers on Mycotoxin Bioaccessibility during...
Lopez Ruiz, R; Marin Saez, J; Cunha, SC; Fernandes, A; de Freitas, V; Viegas, Olga; Ferreira, IMPLVOMycotoxins contamination is a real concern worldwide due to their high prevalence in foods and high toxicity; therefore, strategies that reduce their gastrointestinal bioaccessibility and absorption are of major relevance. The use of dietary fibers as binders of four mycotoxins (zearalenone (ZEA), deoxynivalenol (DON), HT-2, and T-2 toxins) to reduce their bioaccessibility was investigated by in vitro digestion...
Fibre enrichment of cookies to mitigate acrylamide formation and gastrointestin...
López Ruiz, R; Marin Saez, J; Cunha, SC; Fernandes, A; de Freitas, V; Viegas, Olga; Ferreira, IMPLVOAcrylamide (AA) is a food contaminant with serious health effects. In this work, the addition of dietary fibre was proposed to mitigate AA in cookies and to reduce bioaccesibility in the gastrointestinal trac. The analytical methodology applied for AA quantification was based on solid-liquid extraction (SLE) followed by gas chromatography (GC) coupled to mass spectrometry (MS). Preliminar results with commercia...
Nutritional Characterization of Strychnos madagascariensis Fruit Flour Produced...
Chemane, SSI; Ribeiro, M; Pinto, E; Pinho, SCM; Martins, ZS; Agostinho Almeida; Ferreira, IMPLVO; Khan, M; Pinho, Olívia; Susana Casal; Viegas, OlgaThe indigenous fruit Strychnos madagascariensis is usually processed to flour, called nfuma, being highly consumed during staple food shortage. This study aimed to evaluate the nutritional composition of nfuma and its nutrient adequacy. Flours from four districts of Mozambique were analyzed using AOAC methods for proximate composition, HPLC for sugar, amino acids (AA), vitamin E and carotenoids and ICP-MS and F...
