Abstract

Kombucha is a healthy beverage from the fermentation of sugared tea with a symbiotic culture of bacteria and yeast (SCOBY). There is a growing interest on kombucha due to the reported health benefits. The original kombucha is prepared using only sweetened black tea infusion. The development of kombucha, however, has been reported to incorporate other plant water extracts. A previous study showed that kombucha beverage using red dragon fruit (RDF) as an alternative substrate gave the highest antioxidant activity at 15 days of fermentation. RDF kombucha instant powder could be a new food product development due to its longer shelf life, convenience, and low distribution cost. This study aimed to determine the best and the concentration of encapsulating agent for RDF kombucha powdered beverage which could retain the antioxidant properties. RDF kombucha was spray dried using maltodextrin, gum arabic, and inulin as the encapsulating agents with various concentrations (5%, 10%, and 15%). Gum arabic was the best encapsulating agent since it gave the highest values of drying yield, pH, and  total phenolic content retention, in comparison to the other two encapsulating agents. Within the observed concentrations, the incorporation of gum arabic resulted in RDF kombucha powder with a similar appearance, red colour, and antioxidant retention. Thus, the 5% addition of gum arabic is recommended for future preparations of RDF kombucha powdered beverage.

Abstract

Kegiatan gizi ini adalah upaya dari Swiss German University dalam rangka menciptakan generasi penerus yang berkualitas. Program gizi ini bertujuan untuk mengukur dan menyelesaikan masalah gizi di salah satu sekolah di Cisauk, Tangerang Selatan. Metode cross-sectional dengan kuesioner digunakan untuk pengambilan data (n = 220) dalam penentuan masalah gizi. Masalah utama yang ditemukan adalah rendahnya tingkat sarapan siswa (25%) dan pengetahuan gizi yang kurang. Metode intervensi gizi yang dipilih adalah kegiatan penyuluhan, permainan, dan demo masak. Evaluasi intervensi gizi ini menggunakan pre-test dan post-test kuesioner. Hasil pre-test dan post-test menunjukkan meningkatnya jumlah siswa yang memiliki pengetahuan gizi baik dari 38% menjadi 79%. Hal ini menunjukkan adanya peningkatan pengetahuan gizi pada anak sekolah akibat intervensi gizi yang dilakukan. Output yang diharapkan adalah peningkatan pengetahuan gizi siswa sehingga akan berpengaruh kepada jumlah siswa yang sarapan dan selanjutnya meningkatkan prestasi siswa di masa mendatang. Program-program gizi yang berinovasi seperti ini sangat diperlukan untuk menyelesaikan masalah gizi dan kesehatan di Indonesia.
