First insights into macromolecular components analyses of an insect meal using ...
Silva, Flávia Matias Oliveira da; Fidalgo, Liliana G.; Inácio, Rita S.; Fantatto, Rafaela; Carvalho, Maria J.; Murta, Daniel; Pereira, Nuno S. A.The non-invasive nutritional analysis of feed through images captured by hyperspectral cameras represents an innovative and promising approach in the field of biotechnology. With this technology, it is possible to capture images at multiple wavelengths and identify unique spectral patterns associated with different molecular components, such as total fat and moisture. The technique is particularly valuable in b...
Chemical-based methodologies approaches to extend the shelf life of fresh fish ...
Amaral, Renata A.; Pinto, Carlos A.; Lima, Vasco; Tavares, Jéssica; Martins, Ana P.; Fidalgo, Liliana G.; Silva, Ana M.; Gil, Maria M.; Teixeira, PaulaDue to its characteristics, fresh fish is a highly perishable food with a very short shelf-life under refrigeration. Several methods have been introduced to slow down its deterioration, such as by means of oxygen depletion of the food package (vacuum packaging), or by changing the natural atmosphere that is in contact with the fresh fish (modified atmosphere packaging), or by the use of chemicals generally reco...

Autolytic changes involving proteolytic enzymes on Atlantic salmon (Salmo salar...
Fidalgo, Liliana G.; Delgadillo, Ivonne; Saraiva, Jorge A.he effect of hyperbaric storage (HS, 50–75 MPa at 10–37 °C) on proteolytic enzymes and muscle proteins of Atlantic salmon (Salmo salar) was assessed and compared to atmospheric pressure (AP, 0.1 MPa) at the same storage temperature and refrigeration (AP, 5 °C). Generally, activities of acid phosphatase, cathepsin B and D, and calpains decreased when compared to fresh salmon, with a more’ pronounced effect of st...
Physicochemical parameters, lipids stability, and volatiles profile of vacuum-p...
Fidalgo, Liliana G.; Simões, Mário M. Q.; Casal, Susana; Lopes-da-Silva, José A.; Carta, Ana Margarida Salgueiro; Delgadillo, Ivonne; Saraiva, Jorge A.Lipid stability, physical properties and volatiles profile of vacuum-packaged fresh Atlantic salmon (Salmo salar) loins were evaluated after hyperbaric storage at low temperature (HS/LT: 60 MPa/10 °C) and compared to atmospheric pressure and conventional refrigeration (AP/5 °C) after 5, 15 and 30 days, and at low temperature (AP/10 °C), after 5 and 15 days. No variations in drip loss and water holding capacity ...
Growth inhibition and inactivation of Alicyclobacillus acidoterrestris endospor...
Pinto, Carlos A.; Martins, Ana P.; Santos, Mauro D.; Fidalgo, Liliana G.; Delgadillo, Ivonne; Saraiva, Jorge A.Control of endospores of Alicyclobacillus acidoterrestris in pasteurized apple juice using hyperbaric storage at 18 to 23 °C was compared to storage at atmospheric pressure and 18 to 23 °C, as well as refrigeration at ~4 °C for up to 30 days. The juice samples were inoculated with approximately 1 × 105 CFU/mL spores. The juice spoiled quickly at atmospheric pressure and ambient temperature, while under refriger...
Environmental footprint of emerging technologies, regulatory and legislative is...
Castro, Sónia M.; Inácio, Rita S.; Alexandre, Elisabete M. C.; Fidalgo, Liliana G.; Pereira, Sofia; Quaresma, Patrícia; Freitas, Paulo; Teixeira, PaulaConsumers are more demanding, better educated in terms of food quality and nutritional aspects, and forcing producers along with regulatory agencies to search for alternative processing technologies. Some of these technologies like high pressure, pulsed electrical fields, supercritical CO2, ultrasound, ozone, or plasma treatment are at industrially use, pilot scale, or even at the edge of application, but the m...
Enhanced control of Bacillus subtilis endospores development by hyperbaric stor...
Pinto, Carlos A.; Santos, Mauro D.; Fidalgo, Liliana G.; Delgadillo, Ivonne; Saraiva, Jorge A.The effect of hyperbaric storage on Bacillus subtilis endospores, as a new food preservation methodology with potential to replace the conventional refrigeration processes, was assessed and compared to refrigeration. To do so, three different matrices (McIlvaine buffer, carrot juice and brain-heart infusion broth, BHI-broth) were inoculated with B. subtilis endospores and stored at 25, 50 and 100 MPa at variabl...
