AKTIVITAS ANTIOKSIDAN ANTOSIANIN BERAS KETAN HITAM SELAMA FERMENTASI [Antioxidant Activity of Anthocyanin of Black Glutinous Rice During Fermentation] Nanik Suhartatik1)*, Muhammad Nur Cahyanto2), Sri Raharjo2) dan Endang S. Rahayu2) 1) Fakultas Teknologi Pertanian, Universitas Slamet Riyadi Surakarta, Surakarta 2) Jurusan Teknologi Hasil Pertanian, Fakultas Teknologi Pertanian, Universitas Gajah Mada, Yogyakarta   Diterima 07 November 2012 / Disetujui 22 Juli 2013 ABSTRACT   Anthocyanin is a group of bioactive compound found to be abundant in black glutinous rice. It has been widely studied for their health beneficial effect. Hydrolysis of anthocyanin glycoside into anthocyanidin and sugar by β,D-glucosidase is presumed to be the first step in anthocyanin metabolism. Enzymatic degradation of anthocyanin was reported to produce not only more stable compounds, but also healthier compounds with better bioavailability. Some species of Lactic Acid Bacteria showed β,D-glucosidase activity. The research aims to study the functional property’s change’s of anthocyanin extracted from black glutinous rice as an antioxidant compound after being fermented using Lactobacillus plantarum Mut 7. The results showed that fermentation process did not give a significant effect to the antioxidant activity of black glutinous rice anthocyanin. The antioxidant activity as determined by Radical Scavenging Activity and Ferrous Reducing Activity Power value were 59.2% (6 hours of incubation, 30 mM anthocyanin) and 96.7% (5 hours of incubation, 10 mM anthocyanin). The lactic acid bacterial count increased up to 2 log cycle after being fermented for 5 hours.

Abstract

Kombucha has been known as traditional medicine that can cure various diseases, such as hypercholesterol. Kombucha made of fermented sweetened tea using symbiotic growth of khamir and bacteria. Functional properties of kombucha related to metabolite that has been produced during fermentation process, glucuronic acid. The aim of this research was to get a fit carbon source that can produce kombucha which have highest glucuronic acid. The result showed that microbe that dominated at the beginning through the end of fermentation process was a group of khamir, i.e 1.81x107 ; 1.43x106 ; 2.40x107 ; 7.00x104 CFU/mL for 1, 4, 7, and 10% of additive coconut sugar. Kombucha at 4% of coconut sugar yielded 8.86 ppm of glucuronic acid. Meanwhile, kombucha with 10% of coconut sugar yielded 6.22 ppm of glucuronic acid. Total acid has no corelation with glucuronid acid formation during the fermentation process.Key words: kombucha, glucoronic acid, coconut sugar, anticholesterol
