In the brewing production, Aronia berries can be processed into Aronia-brewing wine, healthy vinegar as well as lactic-acid drink. Furthermore, the natural pigment is rich in Aronia berries, such as procyanidins, anthocyanins, flavonoids and so forth. Therefore they can be used as raw materials for the production of natural pigments.

在酿造加工方面，黑果腺肋花楸可用于酿造果酒、酿制保健醋以及研制乳酸发酵型饮料；在天然色素提取方面，黑果腺肋花楸的果实富含原花青素、花色苷、类黄酮等天然色素，因此可作为天然色素生产的原材料。
