Influence of environmental factors on α-tocopherol levels in Moringa oleifera e...
Kessler, Júlia C.; Manrique, Yaidelin A.; Martins, Isabel M.; Ribeiro, António E.; Rodrigues, Alírio; Barreiro, Filomena; Dias, Madalena M.Moringa oleifera L. extracts (Mo) have attracted attention as a sustainable and effective alternative to synthetic ingredients for cosmetic formulations. The unique and diverse phytochemical profile of the Mo tree enhances the quality and appeal of commercial products, as evidenced by numerous studies and patents. Supercritical carbon dioxide extraction (SFE-CO2) is particularly advantageous for this purpose, o...
Bacterial cellulose biosynthesis in the presence of raw moist olive pomace: A g...
Crugeira, Pedro; Khelifa, Halima; Barreira, Luísa; Halla, Noureddine; Barreiro, Filomena; Rodrigues, Paula; Peres, António M.; Schreiner, Tatiana B.In this study, the biosynthesis of bacterial cellulose (BC) by Komagataeibacter intermedius strain isolated from Kombucha tea in the presence of raw moist olive pomace (MOP) (concentration up to 40 % in the fermentation media) was studied. The BC membranes were characterized by their antioxidant activity, structural character- istics, crystallinity, thermal stability, and mechanical behavior. Using raw MOP acti...

Lignin from aldehyde-assisted fractionation can provide light-colored Pickering...
Colucci, Giovana; Ribeiro, Andreia; Figueirêdo, Monique Bernardes; Charmillot, Justine; Santamaria-Echart, Arantzazu; Rodrigues, AlírioColloidal lignin particles (CLPs) are gaining attention as eco-friendly stabilizers for Pickering emulsions. Still, conventional lignin sources, like kraft lignin, are often limited by their dark color and strong odor. This study explores, for the first time, the use of a light-colored lignin derived from an aldehyde-assisted fractionation with glyoxylic acid (GA-lignin) for producing CLPs and derived Pickering...

Closing Editorial: New Insights into Food Ingredients for Human Health Promotion
Ribeiro, Andreia; Barreiro, FilomenaIn recent years, the intersection of food science and health promotion has gained interest. Driven by consumer awareness and a global push toward healthier, safer, and more sustainable food systems, the demand for functional, fortified, and clean-label products has grown substantially. In response to these evolving expectations, this Special Issue of Applied Sciences, titled “New Insights into Food Ingredients ...
Optimizing ultrasound-assisted extraction for enhanced yield of bioactive compo...
Plasencia, Paula; Carocho, Márcio; Finimundy, Tiane C.; Calhelha, Ricardo C.; Molina, Adriana K.; Pires, Tânia C.S.P.; Barreiro, FilomenaDue to the high nutritional value of berries, their extensive production has led to the accumulation of bioresidues. To leverage these residues, the distinct chemical composition, and functional properties of the leaves and other aerial parts can be used to produce high-value ingredients for cosmetics. Ultrasound-assisted extraction (UAE) is considered simple, fast, efficient, and more affordable than other tec...
Extraction of Bioactive Compounds from Rubus Idaeus Bioresidues: A Full Screeni...
Plasencia, Paula; Finimundy, Tiane C.; Carocho, Márcio; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Pires, Tânia C.S.P.; Barreiro, FilomenaPurpose Rubus idaeus cultivation has boosted productivity due to its high nutritional value. In consequence, waste produc- tion increased. The discarded biomass, including leaves and aerial components, can be transformed into valuable functional ingredients for industrial applications, such as cosmetics. Studying their bioactivity potential is highly relevant. Methods According to the present idea, the research...

Teixeira, Liandra Gracher; Silva, Samara Cristina; Colucci, Giovana; Santamaria-Echart, Arantzazu; Peres, António M.; Dias, Madalena M.Anthocyanins (ACNs) are water-soluble bioactive flavonoids found in flowers, roots, leaves, seeds, and stalks. ACNs cover a wide palette of colours, from blue and purple through orange to red1,2. They are used in the food industry (food colourant with E163 code), namely in fruit juice concentrates, nectars, jellies, yoghurts, marmalades, potato chips, ice creams, and soft drinks, replacing the synthetic Red 40 ...
