Olive Leaf
Drying in a way that maintains the amount of polyphenol content
Drying in a way that maintains the amount of polyphenol content
Olive leaf contains many types of polyphenols, the most common being oriuropein and hydroxytyrosol. Research at the University of Tsukuba and others has shown that they have antibacterial, anti-inflammatory, immune-strengthening, vascular, bone and reproductive effects.
Olive leaves grown in Tunisia’s hot and dry climate contain rich oleuropein (5-15% by dry weight), but depending on the drying and storage method, the content is reduced. In order to solve this problem, Harbiotec Aroma, a partner of Sumitomo Corporation, established a technology to dry olive leaves while maintaining the content of oriuropein with technical guidance from Japan. At the same time, no pesticides were detected in 250 kinds of pesticide residue tests conducted by the University of Tsukuba. Our olive leaves are safe and functional, and are expected to be used in fish and livestock feed as well as human supplements.
