Isolation and testing of antioxidant activity with1,1-difenil-2-pikril hidrazil (DPPH) from ethyl acetate extract ofcocoa pod husk(Theobroma cacao L) has been carried out.Theobroma cacaoextract (TCE) showed highly strong antioxidant activity with IC50 = 8,75 ppm and vitamine C = 6,07 ppm as positive control. Isolation of the active components of TCE by column chromatography using silica gel absorbent 60 mesh ASTM (Merck 774) and the eluent n-hexane: ethyl acetate (9:1), obtained 7 fraction combined (TCE 1 to TCE 7). There are 6 combined fractions having the potential as antioxidants, namely TCE 2 to TCE 7 with a range of IC50 (6,46 ppm – 91,8 ppm). TCE 2 fraction has a very strong antioxidant activity with IC50 = 6,46 ppm. Separation of TCE 2 fraction on silica column chromatography obtained 4 combined fractions (TCE 2.1 to TCE 2.4). The test results of antioxidant activity showed that TCE 2.4 had very strong activity with IC50 = 42,7 ppm.For the TCE 2.2 fraction, preparative TLC was carried out using eluent n-hexane: ethyl acetate (9.5: 0,5) obtained by TCE 2.2.4 isolate with a melting point of 114-120 °C and was a steroid class.

Abstract. Wulan R, Astuti RI, Rukayadi Y, Meryandini A. 2021. Evaluation of Indigenous Pichia kudriavzevii from cocoa fermentation for a probiotic candidate. Biodiversitas 22: 1317-1325. Currently, probiotics are becoming a concern along with a healthy lifestyle awareness. Besides bacteria, yeast can be used as a probiotic candidate with specific functional properties. Research on yeast as a probiotic is still limited (except for Saccharomyces boulardii). Previous research has isolated yeasts from the cocoa fermentation process. This study aimed to evaluate the probiotics properties and antioxidant activity of yeast strains isolated from spontaneous cocoa fermentation in Sukabumi, Indonesia. Previous research has isolated 23 yeast strains from spontaneous cocoa (Theobroma cacao L.) fermentation. Of the 23 yeast strains isolated from cocoa fermentation, 22 strains showed negative hemolysis as an indicator of non-pathogenic properties. Ten yeast strains were able to grow at 37 °C and 41 °C, pH 3, 0.5% bile salts, had autoaggregation ability (63.99-95.33%), and co-aggregation with S. typhimurium ATCC14028 (>80%), as character requirement for probiotic candidates. The genetic identification of the ten yeast strains showed that they were 99% identical to Pichia kudriavzevii. Based on its antioxidant activity, the P. kudriavzevii 2P10 metabolites had the highest percentage of inhibition (68.51%) against DPPH free radicals and resistance to H2O2 oxidative stress up to 3 mM. It can be concluded that P. kudriavzevii 2P10 is a promising probiotic candidate for functional foods and health purposes.

Theobroma Cacao L

Anthocyanin is a class of antioxidants that are widely found in the skin of cocoa fruit (Theobroma cacao L.). Anthocyanin degradation occurs not only during the extraction process from plant tissues but also during the storage process. The microencapsulation process can protect the active substance from environmental influences or improve the stability of the preparation. This study aims to characterize anthocyanin microcapsules from cocoa (Theobroma cacao L.) fruit peel using a complex coacervation method, therefore, it can provide economic value added from this plant. Anthocyanin microencapsulation was formulated using a coating of  gelatin: arabic gom with different concentrations of 1:1, 3:2, and 2:1. Microcapsule characterization was organoleptic and morphological test, particle size distribution, moisture content test, absorption efficiency, recovery test, antioxidant activity of the preparation, and FTIR analysis. The results showed that extract yield was 39.82%, optimum microcapsule characterization was obtained from 1: 1 concentration with 36.65% recovery test, 80.40% absorption efficiency, and antioxidant activity with IC50 of 20.52 ppm.
