TOTAL FENOL DAN AKTIVITAS ANTIOKSIDAN BUBUK KULIT MANGGIS (Garcinia mangostana L.) DARI BUAH SEGAR DENGAN VARIASI LAMA PENYIMPANAN YANG DIOLAH SECARA MEKANIS
Abstrak: This study aims to
determine the total content of phenolic compounds and antioxidant activity of
mangosteen skin powder from fresh fruit with variations of storage duration
which processed mechanically. Methods of research done by determining the total
content of phenolic compounds using the method of DPPH free radical scavengers.
The fresh mangosteen skin was dried with a drying oven, with a capacity of 0.12
kg/h and a drying rate of 2.79 kg. Furthermore, dry mangosteen skin was milled
by grinding machine with 2870 rpm rotation and obtained rendemen mangosteen
skin powder as much as 38.04% with water content 8.33%. Total content of
phenolic mangosteen powder with variation of storage duration 0 days, 10 days,
and 20 days ranged 81.17 mgGAE / g - 195.51 mgGAE /g. The range of IC 50 for
the three treatment is 6.80 ppm - 26.47 ppm. The highest total phenolic content
and antioxidant activity werw found at zero days of storage.
