Grape Skin Flour

Grape skin flour is made from the dried skins of grapes, which are a byproduct of winemaking and juice production. The skins are typically milled into a fine powder. It is often used as a natural food coloring and a source of fiber and antioxidants.

Grape skin flour is primarily used as a natural red or purple food coloring. It can also contribute dietary fiber and antioxidants to food products. It is often found in baked goods like crackers and biscotti, as well as in some beverages and confectionery.

Grape skin flour is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of fiber, which can aid digestion, and contains antioxidants like resveratrol, which may have health benefits. The European Food Safety Authority (EFSA) has not specifically evaluated grape skin flour as a distinct additive, but its components are naturally occurring in grapes. Evidence regarding the specific health impacts of concentrated grape skin flour at typical dietary intakes is still developing.
