Anthocyanidin powder is a water-soluble natural pigment naturally present in plants and belongs to the class of flavonoid compounds.
The red and purple color of petals is due to anthocyanidin, and the depth of its color is positively correlated with the content of anthocyanin.
Anthocyanidin is not very stable and is easily affected by light, temperature, and pH. Therefore, when extracting, processing, and preserving products containing anthocyanin, appropriate measures need to be taken to ensure its activity and efficacy.
