6.2.5 Pineapple Peel

Pineapples (Ananas comosus) are harvested throughout the year. From the total weight of the fruit, only 52% is used for consumption, leaving pineapple peel (PAP; 35% of dry weight) and the leaves (13% of dry weight) and being rejected as waste; but, these PAP and leaves are a rich source of valuable bioactive compounds (Krishni et al. 2014; Bardiya et al. 1996; Foo et al. 2011).

The most important and valuable compound is bromelain from PAP. It has antithrombotic, fibrinolytic antiedematous, anti-inflammatory and anticancer properties (Ketnawa et al. 2011; Chobotava et al. 2009; Bhui et al. 2009). Also, in food industries, it is used as a meat tenderizer and dietary supplement (Maurer 2001). Due to the presence of phenolic antioxidants (2.01 mmol FRAP/100 g wet weight), PAP also exhibits antimicrobial and antioxidant activities (Guo et al. 2003).
