Evaluasi Nilai Biologis Protein Rendang dan Kalio Khas Sumatera Barat

Abstract

ABSTRACT Rendang is a traditional Indonesian dishes from West Sumatera whichglobally well known. Inrendang making process, a meat is cooked under long time heat with a large amount of variety spices.Kalio, a rendang similar dishes,is cooked with a shorter heating time and less of spices. Kalio has a few sauce while rendang has no sauce. Long time heating in cooking processmay cause maillard reactionin rendang and kalio. One effect of maillard reaction is lowering the availability of amino acids, consequently could reduce the protein content qualities. To assess the protein nutritional values of rendang and kalio, an in vivo study was conducted using albino rats as animal models. The result showed that cooking process did not confirm any significant differences on feed conversion efficiency, protein efficiency ratio, net protein ratio (NPR), true protein digestibility and biological value (p>0.05)between rendang and kalio, however asignificant difference on net protein utilization (p 0,05) pada feed conversion efficiency (FCE), protein efficiency ratio (PER), net protein ratio (NPR), true protein digestibility (TPD) dan biological value (BV). Akan tetapi pada pengukuran net protein utilization (NPU), terdapat perbedaan yang nyata antara kalio dengan rendang (p<0,05).
