Abstract

Rubus spp. (wild raspberries) is one of genera belongs to Rosaceae, also distributed in the mountain forest of Indonesia. It has a high potency to be cultivated plant. Although, some of the potential of Rubus has already known, information of about fruit nutrients of species that distribute in the mountain forest of Indonesia are not known yet. This study was aimed to determine the fruit nutrients of five species of wild raspberries that was collected in Cibodas Botanical Garden. The results of our experiments demonstrate that the fruits nutrients contents varied among five species of wild raspberries from Indonesian mountain's forests. Rubus fraxinifolius has the highest content of sugar (5.05 g sugar per 100 g fruits) compared to Rubus rosifolius, Rubus chrysophyllus, Rubus lineatus and raspberry. During the ripening and ripe period, there were a different value of vitamin C and iron contents. The highest vitamin C of R. fraxinifolius (83.65 mg/100 gram) on the ripening fruit stage II. On the other hand, the highest vitamin C of R. rosifolius (54.30 mg/100 gram) found on the stage of ripe fruit.

Abstract

Pati resisten adalah jenis pati yang resisten terhadap enzim amilase dalam pencernaan manusia. Pengolahan pati resisten dengan metode autoklaf-pendinginan dapat mengurangi sisa produk sampingan. Namun, proses retrogradasi selama pendinginan membutuhkan waktu lama. Selain itu, penggunaan beras pecah masih sangat terbatas karena kualitas pati yang lebih rendah dibandingkan dengan beras utuh. Oleh karena itu, diperlukan analisis pengaruh suhu dan waktu retrogradasi terhadap produksi pati resisten dari beras pecah, untuk mengetahui pengaruh suhu dan waktu retrogradasi terhadap kandungan pati resisten beras pecah. Retrogradasi dilakukan pada berbagai suhu 4°C, -10°C, dan -20°C dengan waktu retrogradasi 18 dan 24 jam dan diproses menggunakan Randomized Block Design (RBD) faktorial. Hasil penelitian menunjukkan bahwa suhu dan waktu retrogradasi berpengaruh signifikan terhadap kandungan pati resisten pada beras pecah dengan kandungan pati resisten tertinggi ditemukan pada sampel a1b2.
