Stabilization of a nutraceutical omega-3 fatty acid by encapsulation in ultrathin electrosprayed zein prolamine.
2010
Docosahexaenoic acid (DHA) is a long chain polyunsaturated fatty acid of the omega-3 series (omega-3), which exerts strong positive influences on human health. The target of this study was the stabilization by encapsulation of this bioactive ingredient in zein ultrathin capsules produced by electrospraying. The zein ultrathin DHA encapsulation was observed by ATR-FTIR spectroscopy to be more efficient against degradation under both ambient conditions and in a confined space (so-called headspace experiment). In the latter case, that more closely simulates a sealed food packaging situation, the bioactive DHA was considerably more stable. By fitting the degradation data to a specific auto-deco…
Nutraceuticals and Lipid Management
2020
Scientific data support the effectiveness of reducing total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in preventing atherosclerotic disease cardiovascular disease (ASCVD) events. Current guidelines suggest the use of innovative nutritional strategies in lipid management based on consumption of nutraceuticals and functional foods. Nutraceuticals are products isolated or purified from foods (generally sold in medicinal forms), while a functional food is similar in appearance to, or may be, a conventional food. Both nutritional components promote health, lead to better well-being, and reduce risk of cardiovascular disease, possibly by affecting plasma lipid levels. The m…
Biochemical and Immunological implications of Lutein and Zeaxanthin
2021
Throughout history, nature has been acknowledged for being a primordial source of various bioactive molecules in which human macular carotenoids are gaining significant attention. Among 750 natural carotenoids, lutein, zeaxanthin and their oxidative metabolites are selectively accumulated in the macular region of living beings. Due to their vast applications in food, feed, pharmaceutical and nutraceuticals industries, the global market of lutein and zeaxanthin is continuously expanding but chemical synthesis, extraction and purification of these compounds from their natural repertoire e.g., plants, is somewhat costly and technically challenging. In this regard microbial as well as microalga…
Short-Term Effects of a Combined Nutraceutical on Lipid Level, Fatty Liver Biomarkers, Hemodynamic Parameters, and Estimated Cardiovascular Disease R…
2017
Introduction: There is a growing interest in nutraceuticals improving cardiovascular risk factor levels and related organ damage. Methods: This double-blind, placebo-controlled randomized clinical trial aims to compare the effect of a combined nutraceutical containing red yeast rice (10Â mg), phytosterols (800Â mg), and l-tyrosol (5Â mg) on lipid profile, blood pressure, endothelial function, and arterial stiffness in a group of 60 patients with polygenic hypercholesterolemia resistant to Mediterranean diet. Results: After 8 weeks of treatment, when compared to the placebo group, the active treated patients experienced a more favorable percentage change in total cholesterol (â16.3% vs 9.9…
Food quality and nutraceutical value of nine cultivars of mango (Mangifera indica L.) fruits grown in Mediterranean subtropical environment
2019
Mango (Mangifera indica L.) quality is strongly influenced by genotype but individuating the most appropriate harvesting time is essential to obtain high quality fruits. In this trial we studied the influences of the ripening stage at harvest (mature-ripe or green-ripe) on quality of ready to eat mango fruits from nine cultivars (Carrie, Keitt, Glenn, Manzanillo, Maya, Rosa, Osteen, Tommy Atkins and Kensington Pride) grown in the Mediterranean subtropical climate through physicochemical, nutraceutical, and sensory analysis. Our results show a large variability among the different observed genotypes and in dependence of the ripening stage at harvest. With the exception of Rosa, mature-ripe f…
Testing the Short-Term Efficacy of a Lipid-Lowering Nutraceutical in the Setting of Clinical Practice: A Multicenter Study
2015
Abstract The main guidelines for cardiovascular disease prevention suggest that nutraceuticals could be an efficacious tool to improve lipid pattern. Our aim was to carry out a clinical trial comparing the metabolic effects of a combined nutraceutical containing both red yeast rice and polyunsaturated fatty acids (PUFAs) and a phytosterol-based approach in a setting of clinical practice. This was a multicenter open study with parallel control. We consecutively enrolled 107 pharmacologically untreated subjects affected by primary polygenic hypercholesterolemia and metabolic syndrome, assigned to 8-week treatment with a combined treatment with red yeast rice (Dif1Stat®, including 5 mg monacol…
Il sostegno e il miglioramento delle coltivazioni sub-tropicali in Sicilia traggono vantaggio dallo studio e dalla promozione delle loro proprietà nu…
2015
Negli ultimi decenni si è assistito a un continuo progresso scientifico in ambito nutrizionale che ha trovato le sue basi da una parte nella scoperta dei principi nutritivi contenuti negli alimenti e dall'altra nell'elaborazione di precise linee guida a larga diffusione. Un'inadeguata alimentazione, infatti, oltre a incidere sul benessere psicofisico, rappresenta uno dei principali fattori di rischio per l'insorgenza di numerose patologie croniche. Secondo l'Organizzazione Mondiale della Sanità (OMS) il rischio di insorgenza di malattie cardiovascolari, metaboliche e di alcuni tumori si abbassa considerevolmente grazie a una corretta e sana alimentazione.
PROCEDIMENTO PER LA PURIFICAZIONE DI MANNA IMPURA ED OTTENIMENTO DI MANNA ARRICCHITA E SUO IMPIEGO
2015
The invention consists in an original procedure to purify dirty manna, an under-utilized waste matter from the lymph poured from fraxinus plants, to obtain a product comparable with the pure edible “manna”, and enriched in bioactive components with respect to pure manna. Methods to treat the so obtained purified manna are also part of the invention.
Valorisation of urban green areas for producing renewable energy and biochar as growing substrate of Sicilian aromatic and nutraceutical species in a…
2020
This work is aimed at evaluating the possible building up of a gasifier for the energy valorisation of residual biomass deriving from urban areas and their surroundings. The area and the volumes of supply and economic convenience have been determined by implementing a GIS-based geographic method to the localisation and quantification of non-uniform elements of plant biomass. The pyrolysis and gasification processes of the lignocellulosic biomass obtained from pruning and maintenance operations of the urban and ornamental green include the production of a residual amount of biochar. The biochar can be used in agriculture as a soil improver and a substrate alternative to peat in the sustainab…
Biowaste in a circular bioeconomy in Mediterranean area: A case study of compost and vermicompost as growing substrates alternative to peat
2020
European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and comp…
