Evaluation of the potential of annatto seed powder to reduce the formation of h...
Gonçalves, Thaís de Moura Neves; Braga, Anna Rafaela Cavalcante; Pinto, Edgar; Viegas, Olga; Mesquita, Leonardo M. de SouzaVarious 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,...
Unveiling the geographical influence on honey's physicochemical profile: a case...
Soares, Sónia; Magalhães, Leandro; Moreira, Manuela M.; Rede, Diana; Fernandes, Virgínia Cruz; Viegas, Olga; Pinto, Edgar; Almeida, AgostinhoIn recent years, global honey consumption has significantly increased due to the rising demand for natural products with health benefits. Consumers are particularly drawn to honey recognized for its superior quality, such as Protected Designation of Origin (PDO) honey or honey produced in protected areas, which is associated with distinctive characteristics. Portugal stands among the top producers of PDO honey,...
An eco-friendly approach for analysing sugars, minerals, and colour in brown su...
Alves, Vandressa; Santos, Jeferson M. dos; Viegas, Olga; Pinto, Edgar; Ferreira, Isabel M.P.L.V.O.; Lima, Vanderlei Aparecido; Felsner, Maria L.Brown sugar is a natural sweetener obtained by thermal processing, with interesting nutritional characteristics. However, it has significant sensory variability, which directly affects product quality and consumer choice. Therefore, developing rapid methods for its quality control is desirable. This work proposes a fast, environmentally friendly, and accurate method for the simultaneous analysis of sucrose, red...
Exploring geographical influences on physicochemical characteristics of honey: ...
Soares, Sónia; Magalhães, Leandro; Moreira, Manuela M.; Rede, Diana; Fernandes, Virgínia Cruz; Viegas, Olga; Pinto, Edgar; Almeida, AgostinhoIn recent years, there has been a substantial increase in the global consumption of honey, driven by the high demand for natural products that offer health benefits. Consequently, consumers show a preference for honey, recognised for its superior quality, namely honey with a Protected Designation of Origin (PDO) or honey produced in protected areas, as it is associated with superior attributes and characteristi...
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...
In vitro bioaccessibility and intestinal transport of retinoic acid in ethyl ce...
Gonçalves, A; Viegas, Olga; Faria, A; Ferreira, MPLVO; Rocha, F; Estevinho, NThe development of carrier-based delivery systems for oral administration of retinoic acid (RA), that provides its release and absorption at intestinal level, is of major relevance in the treatment of acute promyelocytic leukemia. The aim of this work was to evaluate RA bioaccessibility and intestinal transport on ethyl cellulose (EC)- and EC + polyethylene glycol (ECP)-based microparticles and to understand th...
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...
