Antioxidants | Free Full-Text | Impact of Cold versus Hot
Consumption of rooibos (Aspalathus linearis) as herbal tea is growing in popularity worldwide and its health-promoting attributes are mainly ascribed to its phenolic composition, which may be affected by the brewing conditions used. An aspect so far overlooked is the impact of cold brewing vs regular brewing and microwave boiling on the (poly) phenolic profile and in vitro antioxidant capacity

Maceration Before and During Fermentation: Effect on
Phenolic compounds and antioxidant activities of ten juices from arils and whole pomegranate cultivars grown in Iran were studied. Phenolic contents and antioxidant activities of juices from whole pomegranate fruit were significantly higher than juices from pomegranate arils, but the variety has a greater influence than the processing method.

Phenolic Compounds in Honey and Their Associated Health
Abstract: Honey is a natural substance appreciated for its therapeutic abilities since ancient times. Its content in flavonoids and phenolic acids play a key role in human health, thanks to the high antioxidant and anti-inflammatory properties that they exert. Honey possesses antimicrobial capacity and anticancer activity against different types of tumors, acting on different molecular
