Domestication of underutilized indigenous plant Garcinia latissima Miq. through fruit jam production.

Garcinia latissima Miq. belongs to Clusiaceae and is locally known as dolomagota or manggis papua. The fruits contain numerous beneficial phytochemical compounds, such as flavonoids, tannins, saponins, and alkaloids. Antimicrobial activity is foundto be presented in the extract of this indigenous fruit that is capable of inhibiting the development of certain pathogens. Although it carries great potential as food or medicinal products, people have not fully utilized this fruit. The lack of scientificinformation about this plant and a relatively short period of fruit shelf life is likely to be the main factors contributing to the minimum utilization of this fruit. Therefore, this study develops the post-harvest technology of this underutilized indigenous plant through production a fruit jam as a simple and well-accepted product. We revealed that the fresh fruit of G. latissima had a comparable vitamin C to the widely common fruits. Organoleptic analysis exhibited that the fruit jam derived from 1 kg fruit pulp+1 kg sugar+2 g cornstarch was the most acceptable formula, according to the panelists. Furthermore, theorganoleptic-test-selected fruit jam also contained 21.8 mg/ 100 g vitamin C, 0.24% protein, 0.26% fat, and 0.10% ash. [ABSTRACT FROM AUTHOR]
