Integral Extraction of Opuntia ficus-indica Peel Bioproducts via Microwave-Assisted Hydrodiffusion and Hydrodistillation

2019

The microwave-assisted hydrodiffusion extraction process affords high quality pectin and betanin from the peel of red and green Opuntia ficus-indica fruits under mild conditions. An aqueous mixture of valued bioproducts is readily obtained from the fruit peel cell water itself, without any water addition. The integral extract can be used as such to formulate nutraceutical beverages and products or, upon straightforward separation, to isolate pectin and betanin devoid of chemical contaminants suitable as ingredients for products ranging from food and beverage to cosmetic and pharmaceutical sectors. Betanin shows exceptional stability thanks to the high amounts of antioxidant polyphenols in t…

Fatty Acids and Triacylglycerols Profiles from Sicilian (Cold Pressed vs. Soxhlet) Grape Seed Oils

2021

Among the Sicilian economic productive sectors, that of wine production has today a considerable economic value. However, with the growth of this sector, notable was the increase in the production of waste, which to date is not only an economic damage for companies, but also a threat to the environment. It is known that waste from wine production has properties (e.g., antioxidants) which have potential reuse at cosmetic, pharmaceutical and nutritional levels to obtain economically sustainable applications. A new goal is given by the recovery of added value compounds from agri-food wastes and by-products. Grape seed oil is a promising vegetable fat and cold pressing does not involve the use …

Protecting from Oxygen (and from other gases)

2016

As mentioned in previous chapters, the benefits provided by innovation in the paper and board business are connected with the possible chemical modification of fibres, with coupling with other materials (composites), as well as with special surface treatments. Today paper and board can substitute polymers by virtue of their enhanced ability to act as barriers to gases, while displaying an active, antimicrobial, photocatalytic, etc. behaviour. The desired barrier effect is primarily against oxygen. Considerable interest was aroused in the past by substances like artificial or natural antioxidant additives, capable to act as a barrier to oxygen by preventing its action, as well as by solution…

Régimes passionnels de l'excès

2022

Si l’alimentation constitue un marqueur de santé et de plaisir, idéalement à la jonction du bien et du bon, les addictions alimentaires renvoient plus directement à l’univers des troubles, des compulsions, du désordre dans le rapport aux aliments, à l’alimentation. Mais, en dehors du discours nutritionnel ou médical, on peut aussi concevoir l’addiction dans un rapport plus complexe à la séduction alimentaire, au plaisir gastronomique, jouant avec l’excès, l’expérience des limites. Jusqu’à basculer et se perdre par rapport à la recherche initiale et idéale du plaisir alimentaire.

The influence of backslopping on lactic acid bacteria diversity in tarhana fermentation

2020

Tarhana is produced at batch systems in which the microbiota has changed accordingly to the microbial load from ingredients. In order to stabilize the microbiota, the effects of backslopping carried out under different temperature regimes (25 and 30 °C), pH (3.70 and 4.00) and inoculation rates (5, 10 and 15%) on lactic acid bacteria (LAB) diversity were determined in tarhana dough. LAB and Total Aerobic Mesophilic Bacteria (TAMB) numbers increased in all tarhana dough samples subjected to backslopping. Temperature and pH significantly affected the microbiological diversity of tarhana whereas the different inoculation rates did not. Tarhana dough showed complex tarhana microbiota following …

Factors associated with milk urea concentrations in Girgentana goats

2010

A total of 1,481 milk samples of 166 Girgentana goats, taken along the entire lactation, were utilised to evaluate the effect of non nutritional factors on milk urea (MU). Parity, stage of lactation and month of sampling significantly influenced MU, while no effect was found for born kids number. The first kidding goats produced lower MU than multiparous goats. Trend of MU was similar to milk production course with a peak found at 60 DIM. The different MU levels between several months of production are often linked to pasture chemical variations.

Rapid Assessment of Gray Mold (Botrytis cinerea) Infection in Grapes with a Biosensor System

2015

Abstract: Botrytis cinerea is the causative agent of gray mold disease, which causes considerable economic losses to winemakers. The extent of gray mold infection of winegrapes is commonly visually estimated, a method that is prone to assessor bias. Here, we used rapid and simple enzyme-based screening consisting of carbon-electrode, screen-printed amperometric biosensors to estimate gluconic acid and glycerol concentration in winegrapes infected with different degrees of B. cinerea. The lower limits of quantification of the screen-printed amperometric biosensors were 3 mg/L for gluconic acid (corresponding to an infection rate of less than 1%) and 35 mg/L for glycerol; the response times w…
