Abstract
| - Bergamot peel is an underutilized byproduct of the essential oil and juice-processing industry. Aswith other Citrus peels, it still contains exploitable components, such as pectins and flavonoids.Commercial glycoside hydrolases, specifically a combination of pectolytic and cellulolytic enzymes,solubilized a high percentage of the material (81.94%). The flavonoid profile of the peel consisted ofcharacteristic Citrus species flavanone rutinosides and neohesperosides derived from naringenin,eriodictyol, and hesperetin. In addition, a number of minor flavanone and flavone glycosides, notfound in orange and lemon peels, were identified. The majority of flavonoids were extracted in thetwo 70% v/v EtOH extractions. Processing this material clearly has economic potential leading tolow environmental impact.
