KARAKTERISTIK KWETIAU DARI TEPUNG BERAS MERAH (Oryza sativa): Characteristics of Kwetiau Made of Red Rice (Oryza sativa) Flour

ABSTRACT The objective of this research was to analyze the characteristics of kwetiau made of red rice flour with binding agents addition and soaking time of red rice. This research used a Factorial Completely Randomized Design with two factors. The first factor was types of binding agent (tapioca, glutinous rice flour and sago), and the second factor was the soaking time (1.5 hours and 3 hours). The observed parameters were physical (color, texture, elongation), chemical (moisture, ash, crude fiber, total anthocyanin content, and sensory characteristics (flavor, color, texture, taste). The results showed that the types of binding agent had significant effects on texture, elongation, and moisture content, while the soaking time had significant effects on color (L*, a*, b*), texture, moisture and ash content. Interaction of binding agent and soaking time had significant effects on texture and moisture content. Based on sensory characteristics and moisture content (Indonesian National Standard No. 2987-2015), the best treatment was kwetiau A1B1 (tapioca as binding agent; 1.5 hours of soaking time). Keywords: binding agent, kwetiau, red rice flour, soaking time ABSTRAK Penelitian ini bertujuan untuk menganalisa karakteristik kwetiau dari tepung beras merah dengan penambahan beberapa jenis bahan perekat dan lama perendaman beras merah. Penelitian menggunakan Rancangan Acak Lengkap faktorial dengan dua faktor perlakuan, yaitu jenis bahan perekat (tapioka, tepung beras ketan, dan sagu) dan lama perendaman beras merah (1,5 jam dan 3 jam). Parameter yang diamati adalah karakteristik fisik (warna, kekerasan, elongasi), kimia (air, abu, serat kasar, total antosianin), dan sensoris (flavor, warna, tekstur, rasa). Hasil penelitian menunjukkan bahwa jenis bahan perekat berpengaruh nyata terhadap kekerasan, elongasi dan kadar air, sedangkan lama perendaman berpengaruh nyata terhadap warna (L*, a*, b*), tekstur, elongasi, kadar air dan abu. Interaksi antara jenis bahan perekat dan lama perendaman berpengaruh nyata terhadap tekstur dan kadar air kwetiau tepung beras merah. Perlakuan terbaik ditentukan berdasarkan karakteristik sensoris dan parameter kadar air (SNI 2987-2015), perlakuan terbaik adalah kwetiau A1B1 (bahan perekat tapioka; lama perendaman beras merah 1,5 jam).
