A kind of purple potato noodles with high anthocyanin preservation rate and preparation method thereof

Abstract

The invention discloses a purple potato noodle with a high anthocyanin preservation rate and a production method thereof. The method comprises the following process steps: after the purple potato is fermented twice successively, it is mixed with gluten powder, sweet potato polyphenols, pueraria flavonoids, high gluten The flour is mixed, and the noodles are kneaded, waked up, pressed, cut, and dried to obtain purple potato noodles.
