Product Description
Evergreen Purple Sweet Potato Extract is sourced from organic plantations in Shandong and Henan (varieties: Jishu 26, Xuzi 8). Using low-temperature extraction and purification technology, it preserves natural anthocyanins, dietary fiber, and micronutrients.
Compared with ordinary sweet potatoes, purple varieties contain 10–15 times higher anthocyanin levels and are recognized globally as functional ingredients. The extract retains natural flavor and color while delivering dual benefits of natural coloring and nutrition enhancement, perfectly aligned with the "clean label" trend.
