In South Korea, researchers have found a way to create natural pigments that can be used as additives in processed foods, supplementary health foods and medicines or as a raw material in blushers and lipsticks.
The Apple Use Research Institute in South Korea – part of the Gyeongsangnam-do Agricultural Research and Extension Services – has introduced a reddish natural pigment sourced from wasted apple peel and crab apples.
A study conducted by the institute reports that red and black apples and Arnold apples are the most ideal option to develop the pigments.
Apple peel contains reddish natural pigments called anthocyanins, and crab apples are wasted because of their sour and astringent taste. In discovering their use as materials in natural pigments, the researchers have found a sustainable solution to reducing the waste of fruits.
This is not the first time we have been able to report on new uses for waste apple peel. These vegan boots are made from apple skin.
