Edible insect powder, particularly from the cricket Acheta domesticus L., is a promising sustainable alternative to traditional livestock-derived protein. Insects provide high protein content, fibre, and essential minerals, making them suitable for food applications. This study investigates viability of diets rearing A. domesticus. Two experimental were tested: RI [50% horticultural by-products (HP) + 50% commercial diet (CD)] RII (33% HP 33% CD fish by-products). The results demonstrated...
ABSTRACT In this work, the effect of excess copper (Cu) on tomato plants grown in hydroponic solutions for up to 15 days was studied. The contained different Cu concentrations ranging from 0.05, 0.15, 0.20, and 0.35 mM Cu. Dry mass, root length, foliar area decreased with time solution concentration. Copper accumulated more heavily roots than leaves. Mineral uptake affected by increasing calcium (Ca), iron (Fe), zinc (Zn) contents leaves decreasing. Except Ca, these elements also decreased,...
Yellow lupin (Lupinus luteus L.) plants were grown in hydroponic solution for 15 d under different copper concentrations (0.1, 0.5, 1.0, 10, 25 and 50 µM). With increasing Cu concentration total biomass was not affected, leaf area slightly decreased, while chlorophyll content decreased considerably. increased significantly both roots leaves, but the contents of other ions only affected at highest (Mn P leaves Zn roots). Superoxide dismutase (SOD) activity up to day 7 after application....
Abstract The presence of different bioactive compounds in virgin olive oil affects its nutritional, oxidative and sensorial properties. Phenolic are endogenous highly susceptible to degradation. Olive oxidoreductases, mainly polyphenol oxidases (PPO) peroxidases (POD), may play an important role on the profile by promoting oxidation phenolic compounds. aim this study was evaluate if changes PPO POD activities fruits from two Portuguese cultivars ( Olea europaea , cv ‘Cobrançosa’ ‘Galega...
The aim of this work was to optimize olive oil extraction, at laboratory‐scale (Abencor system), from fruits “Cobrançosa” and “Galega Vulgar” Portuguese cultivars, either in the absence or presence enzymes natural microtalc. Using a Placket–Burman design select significant variables followed by central composite rotatable (CCRD), Abencor operation conditions were optimized: no water addition 30 min malaxation 14% w/w 50°C centrifugation. combined effects concentrations microtalc (MT:...
In this work we studied the effect of cadmium (Cd) (25 μM), in spinach plants (Spinacea oleracea) growing nutrient solution, for 1, 2 and 7 days. Spinach contaminated solution showed a decrease biomass, chlorophyll content an increase malondialdehyde (MDA) content, showing that photosynthetic apparatus was affected lipid peroxidation occurred. The main defence mechanisms against induced oxidative stress were activation catalase, glutathione reductase guaiacol peroxidase. Glutathione activity...
Flavoring olive oils is a new trend in consumer preferences, and different enrichment techniques can be used. Coextraction of olives with flavoring agent an option for obtaining flavored product without the need further operations. Moreover, ultrasound (US) assisted extraction emergent technology able to increase extractability. Combining US coextraction, it possible obtain products using types (e.g., cultivar ripening stage), ingredient(s) greatest and/or bioactive potential, as well...
