Science
Mechanism of Action
This ingredient operates via its rich composition of bioactive polyphenols, including delphinidin-rich anthocyanins, flavonoids, coumarins, caffeic acid, and ferulic acid. These compounds efficiently neutralize free radicals, safeguarding cellular integrity from oxidative damage. Furthermore, it modulates inflammatory pathways and has demonstrated photoprotective action on human skin fibroblasts exposed to UVB.

Stability
Aristotelia Chilensis Fruit Juice is highly sensitive to temperature, light, and pH variations. Its key bioactive anthocyanins exhibit optimal stability at acidic pH levels, with the flavylium cation stable at pH 1 (fresh fruit pH is approximately 3.90). To preserve its total anthocyanin content and antioxidant capacity, processing and storage should be conducted under cold and dark conditions, avoiding temperatures exceeding 40°C.
