Antioxidant Activity of Crude Bromelain of Pineapple (Ananas comosus (L.) Merr) Crown from Subang District, Indonesia

BACKGROUND: Antioxidants are chemical compounds that can donate one or more electrons to free radicals to prevent degenerative diseases. The crown of pineapple (Ananas comosus (L.) Merr.) contains bromelain, that is, a proteolytic enzyme, which can act as an antioxidant. AIMS AND OBJECTIVES: The aim...

Sumario:BACKGROUND: Antioxidants are chemical compounds that can donate one or more electrons to free radicals to prevent degenerative diseases. The crown of pineapple (Ananas comosus (L.) Merr.) contains bromelain, that is, a proteolytic enzyme, which can act as an antioxidant. AIMS AND OBJECTIVES: The aim of this study was to determine the antioxidant activity of crude bromelain from pineapple crowns that were collected from Subang district, West Java, Indonesia. MATERIALS AND METHODS: Antioxidant activity was determined by the method of 2,2-diphenyl-1-picrylhydrazyl (DPPH) with vitamin C as a standard and measured with visible spectrophotometer. RESULTS: The pineapple crown was produced 0.26% of dried crude bromelain with total protein content 44.10% and IC(50) value 3624 μg/mL of crude bromelain, which was equivalent to 1590.18 μg/mL of total protein. CONCLUSION: Crude bromelain has medium antioxidant activity.
