PVPP blend for treatment of oxygen sensitive juice and wine
White, Rosé, Fruit
Freshprotect is a proprietary IOC blend of polyvinylpolypyrrolidone (PVPP), bentonite and arabic gum. It was specifically formulated to help minimize problems associated with the oxidation of polyphenols including color, bitterness and herbaceousness in oxygen sensitive juice. These characteristics are significantly mitigated with the use of Freshprotect. PVPP is intended as a processing aid. Wines made with it must be racked or filtered afterwards. Freshprotect has also been known to help correct sensory off-aromas.
