C18 alkyl-modified silica: A suitable tool for olive biophenol green extraction

2017

Abstract A clean and straightforward methodology to assess the value of olive mill wastewater (OMWW) samples as well as to obtain biophenol-rich oils that can find employment in a variety of cosmetic, nutraceutical and pharmaceutical products is described. The method employs chromatographic spherical organosilica microparticles, coupled to advanced analytical techniques. OMWW samples obtained in Sicily from two different organically grown cultivars during the exceptional 2015/2016 olive oil season were analyzed, leading us to establish the conditions for optimal extraction of hydroxytyrosol and tyrosol.

New formulation with potential for the prevention and treatment of osteoporosis and osteoarthritis

2013

ObjectiveThe aim of this study was to investigate the effect of a new formulation in a combined rat model of Osteoporosis (OP) and Osteoarthritis (OA). The nutraceutical formulation (BIS073) contai...

Harmful Interference of Detoxifying Diets and Nutraceuticals with Adherence to Abemaciclib in Advanced Estrogen Receptor-Positive, Human Epidermal Gr…

2021

Many cancer patients use integrative therapies with a combination of natural products and diets. In the Western world, integrative medicine is often not shared with oncologists even during antineoplastic treatments. This behavior stems from the unmet needs of cancer patients who may feel oncologists’ underestimation of their symptoms and spiritual aspects. This case report demonstrates the potential harm of inadequate diet and nutraceutical intake in a 68-year-old woman with metastatic estrogen receptor-positive, human epidermal growth factor receptor-2-negative breast cancer. Her care team recommended hormone therapy with abemaciclib plus fulvestrant. Her diarrhea started after 10 days of …

Nutraceutical Value of Pantelleria Capers (Capparis spinosa L.)

2019

Abstract: Unopened flower buds of Capparis spinosa L. (capers), generally used in the Mediterranean area as food flavoring, are known to be a good source of bioactive compounds. The aim of this work was to evaluate the nutraceutical value of salt-fermented capers collected from different areas of Pantelleria Island (Italy), testing their methylglyoxal and glyoxal trapping capacity and antioxidant activity by 2,2-diphenyl-1-picryl hydrazyl (DPPH), [2,2-azinobis(3-ethylben- zothiazoline-6-sulfonic acid)] diammonium salt (ABTS), and oxygen radical absorbance capacity (ORAC) assays. Hydrophilic extracts were also characterized by high-performance liquid chromatography–electrospray ionization/ma…

Effect of surround WP (a Kaolin-based particle film) on Ceratitis capitata infestation, quality and postharvest behavior of cactus pear fruit cv Gial…

2021

ABSTRACT A Kaolin-particle film (Surround WP) was applied at 3% to cactus pear (Opuntia ficus-indica cv Gialla) to assess its capacity to Control medfly (Ceratitis capitata Wiedemann) infestation and to evaluate its effects on the quality and postharvest behavior of treated fruit. In the first trial, Kaolin was applied at the end of July when fruit were green and about two weeks later, at color breakage. Its efficacy was compared with a standard organophosphate insecticide (Phosmet). The experiment was conducted in two locations in 2014 and 2015. Kaolin application was very effective in preventing medfly attacks until natural fruit drop in November. Kaolin treated fruit were harvested at th…

Recovery of colorants from red prickly pear peels and pulps enhanced by pulsed electric field and ultrasound

2016

Abstract The aim of this work was to evaluate the potential of the non-conventional pre-treatments; pulsed electric fields (PEFs) and ultrasounds (USNs), to enhance the extraction of red colorants from red prickly pear ( Opuntia stricta Haw.) peels and pulps. The overall goal was to valorize the thick part of the fruit, being discarded for fruit's consumption. PEF and USN treatments were first optimized using fruit slices, followed by a supplementary aqueous extraction (+ SAE) up to 1 h. The optimal conditions were then applied for peels and pulps, separately. Results showed that PEF + SAE and USN + SAE enhanced significantly the extraction of red colorants (betanin/isobetanin), compared to…

Extraction of Phenolic Compounds from Fresh Apple Pomace by Different Non-Conventional Techniques

2021

Red Delicious apple pomace was produced at laboratory scale with a domestic blender and different non-conventional extraction techniques were performed to isolate phenolic compounds, such as ultrasound-assisted extraction (UAE), ultraturrax extraction (UTE), accelerated solvent extraction (ASE) and pulsed electric field (PEF) extraction pre-treatment. Total phenolic content (TPC) was determined by Folin–Ciocalteu assay. Phloridzin, the main phenolic compound in apples, was determined by chromatographic analysis Q-TOF-LC/MS. The results obtained with these techniques were compared in order to identify the most efficient method to recover polyphenols. The highest value of TPC (1062.92 ± 59.80…

Nutraceutical approaches to non-alcoholic fatty liver disease (NAFLD): A position paper from the International Lipid Expert Panel (ILEP)

2023

Non-Alcoholic Fatty Liver Disease (NAFLD) is a common condition affecting around 10–25% of the general adult population, 15% of children, and even > 50% of individuals who have type 2 diabetes mellitus. It is a major cause of liver-related morbidity, and cardiovascular (CV) mortality is a common cause of death. In addition to being the initial step of irreversible alterations of the liver parenchyma causing cirrhosis, about 1/6 of those who develop NASH are at risk also developing CV disease (CVD). More recently the acronym MAFLD (Metabolic Associated Fatty Liver Disease) has been preferred by many European and US specialists, providing a clearer message on the metabolic etiology of the dis…

Effect of O2 control and monitoring on the nutraceutical properties of extra virgin olive oils

2016

Abstract The presence of oxygen during malaxation has key role in improving Extra Virgin Olive Oil (EVOO) quality in terms of volatile and phenolic compounds. The objective of this study was to evaluate the influence of the head space malaxer oxygen concentration on the physicochemical characteristics and nutraceutical properties of EVOO from the Nocellara del Belice olives. The acidic compounds were related to the concentration of the oxygen presented in the machine headspace considering a new software application for the online oxygen management opportunely designed and applicable to all the existing plants. The right timepoint and oxygen concentration of the malaxation process was establ…
