Bergamot peel is an underutilized byproduct of the essential oil and juice-processing industry. As with 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 of characteristic Citrus species flavanone rutinosides and neohesperosides derived from naringenin, eriodictyol, and hesperetin. In addition, a number of minor flavanone and flavone glycosides, not found in orange and lemon peels, were identified. The majority of flavonoids were extracted in the two 70% v/v EtOH extractions. Processing this material clearly has economic potential leading to low environmental impact.
佛手柑皮是精油和果汁加工行业未得到充分利用的副产品。与其他柑橘皮一样，它仍然含有可利用的成分，如果胶和类黄酮。商业糖苷水解酶，特别是果胶分解酶和纤维素分解酶的组合，溶解了高比例的物质（81.94%）。果皮中的类黄酮谱由来自柚皮素、圣草酚和橙皮素的典型柑橘类黄烷酮芸香糖苷和新橙皮糖苷组成。此外，还鉴定出一些在橙子和柠檬皮中未发现的次要黄烷酮和黄酮糖苷。大部分类黄酮是在两次70%（v/v）乙醇萃取中提取的。加工这种材料显然具有经济潜力，且对环境影响较小。
