Abstract

Artificial rice is one of food diversification alternative from non-rice local carbohydrates. Generally, artificial rice is a flour based using cassava, tapioca, corn and sago from Indonesia as raw material, with additional of micronutrients such as mineral and vitamin. This research aimed to apply the red pigment anthocyanin which contain antioxidants for artificial red rice production. Red pigment was extracted from Adam hawa (Rhoeo discolor L. Her) leaves in acid water solvent and predicted as cyanidin-3-galactose or peonidin-3-glucose compounds. Artificial red rice was tested its color degree based on the CIE (Commission Internationale de I'Eclairage) Lab method and the result indicated the red color brightness and its color stability lighter than natural red rice.

Keywords: Anthocyanins, antioxidants, artificial rice, Rhoeo discolor L. Her

ABSTRAK

Beras artificial menjadi salah satu alternatif diversifikasi pangan berbahan baku karbohidrat lokal bukan beras. Umumnya, beras artificial menggunakan bahan baku berbasis tepung seperti singkong, tapioka, jagung dan sagu asal Indonesia, serta tambahan mikronutrien seperti mineral dan vitamin. Penelitian ini bertujuan untuk mengaplikasikan pewarna merah antosianin yang mengandung antioksidan untuk pembuatan beras merah artificial. Pewarna merah diekstrak dari bagian daun Adam hawa (Rhoeo discolor L. Her) dalam pelarut air (akuades) yang mengandung asam dan diperkirakan sebagai senyawa sianidin-3-galaktosa atau peonidin-3-glukosa. Produk beras merah artificial diuji derajat warnanya mengacu nilai Lab CIE (Commission Internationale de I’Eclairage) dan jika dibandingkan dengan beras merah alami maka beras merah artificial menunjukkan skala pembacaan warna merah, kecerahan, serta kestabilan warna merahnya ke arah lebih terang.
