The invention consists in a special regulation method of the horizontal axes of operating and rubbing wheels of a centerless grinding machine coupled with an opportune blade profile, allowing a continuous regulation of blade rest angle (angle between tangent to blade profile at the contact point with the work piece and the horizon, denoted by γ) and workpiece height (denoted by hw), without requiring blade substitution and/or manual regulations.

Environmental contamination is a prominent topic. Where the exposure to contaminants such as heavy metals (HMs) or polycyclic aromatic hydrocarbons (PAHs) is greater, the incidence of chronic degenerative diseases, such as oncologic, is increased. Scientific evidence reports that some phytochemicals are able to interact with HMs and PAHs by interfering with their cellular metabolism, inhibiting their cytotoxic mechanisms or helping to reduce tissue concentrations.

Grape pomace, a by-product of wine-making, is rich in polyphenols, metals, organic acids and can become a functional ingredient in food and beverage. The stabilisation of the pomace has been optimised to preserve the anti-inflammatory and antioxidant properties of the molecules present. Isolated grape skins have been reused in purity or in blends with other plant components as a base for: 1) herbal teas, 2) ready-to-drink functional beverages, 3) freeze-dried products.
