Waste orange peel represents a heavy burden for the juice industry, estimated in several million tons per year worldwide; nevertheless, this by-product is endowed with valuable bioactive compounds, such as pectin, polyphenols, and terpenes. The potential value of waste has stimulated search extraction processes, alternative or complementary to landfilling integral energy conversion. This study introduces controlled hydrodynamic cavitation new route valorization by-product, based on simple...
The prolonged lockdown imposed to contain the COrona VIrus Disease 19 COVID-19 pandemic prevented many people from direct contact with nature and greenspaces, raising alarms for a possible worsening of mental health. This study investigated effectiveness simple affordable remedy improving psychological well-being, based on audio-visual stimuli brought by short computer video showing forest environments, an urban as control. Randomly selected participants were assigned or video, look at...
Chemical extraction, water retting, microbiological and enzymatic methods were applied on entire nettle stalks and/or unretted decorticated fiber of a selected clone. Morphological mechanical properties chemical composition then determined samples. The first interesting result concerned the good degree separation between fibers shives obtained by scutching stored for 1 year, probably resulting from natural retting processes occurring during storage. Microbiological (anaerobic plus aerobic...
Abstract This study offers a unified perspective into the unexpected solar energy photovoltaic revolution, and its far reaching impact onto both generation electricity markets. Practically relevant aspects, such as those related to value of PV electricity, land consumption, return on invested, reliability technology, structure global industry, cost Li ion batteries market trends are clarified. We identify main barriers overcome for expand beyond niche (say, <10% country's power...
Grapefruit and lemon pectin obtained from the respective waste citrus peels via hydrodynamic cavitation in water only are powerful, broad-scope antimicrobials against Gram-negative -positive bacteria. Dubbed IntegroPectin, these pectic polymers functionalized with flavonoids terpenes show superior antimicrobial activity when compared to commercial pectin. Similar pectin, IntegroPectin determined ca. 3-log reduction Staphylococcus aureus cells, while an enhanced of was detected case...
Abstract Pectin extracted via hydrodynamic cavitation in water only from waste lemon peel and further isolated freeze drying displays significant antibacterial activity against Staphylococcus aureus , a Gram positive pathogen which easily contaminates food. The effect of the new IntegroPectin is largely superior to that commercial citrus pectin, opening way advanced applications bioproduct now obtainable large amounts at low cost juice industry's waste.
Extracts from parts of coniferous trees have received increased interest due to their valuable bioactive compounds and properties, useful for plenty experimental consolidated applications, in fields comprising nutraceutics, cosmetics, pharmacology, food preservation, stimulation plant growth. However, the variability complexity extraction methods, use potentially harmful synthetic chemicals, still represent an obstacle spreading such natural compounds. Hydrodynamic cavitation is emerging as...
Abstract Lemon pectin extracted along with water‐soluble flavonoids and other phytochemicals from citrus industry's waste lemon peel via hydrodynamic cavitation in water, directly at pre‐industrial scale further isolated freeze drying, shows exceptionally high antioxidant non‐cytotoxic activity. Preliminary investigation indicates also significant antimicrobial These findings open the route to development of new nutraceutical healthcare applications a versatile biopolymer endowed...
Abstract Pectin recovered via hydrodynamic cavitation (IntegroPectin) from lemon and grapefruit agri-food waste intrinsically containing antimicrobial bioactive substances (flavonoids, phenolic acids, terpenes, terpenoids) was used to generate innovative eco-compatible films that efficiently inhibit the growth of Gram-negative pathogens. Extensive characterization confirmed presence these substances, which differently interact with polysaccharide polymer (pectin), plasticizer (glycerol),...
