Penetapan Kadar Pektin dan Metoksil Kulit Buah Naga Merah (Hylocereus Polyrhizus) yang Diekstraksi Dengan Metode Refluks
Salah satu buah yang banyak dimanfaatkan di Indonesia adalah buah naga merah (Hylocereus polyrhizus). Buah naga merah banyak dikonsumsi secara langsung atau diolah menjadi jus, agar-agar, dan pewarna alami, sedangkan kulitnya mengandung pektin ± 10,8% . Pektin merupakan komponen tambahan dalam industri makanan, farmasi dan kosmetik, pektin digunakan sebagai pengental, pengikat, obat-obatan. Tujuan penelitian ini adalah untuk mengetahui kadar pektin yang terdapat pada kulit buah naga merah. Pengambilan pektin yang terdapat pada kulit buah naga merah dilakukan dengan metode ekstraksi menggunakan pelarut asam klorida (HCl) 0,35 N.
