Abstract
Starch Noodles (SN) are produced from purified starch or combined flour from various plant sources. Sago starch is one of indigenous Indonesian flours that can be used for making SN. The physical characteristics that greatly affect the quality of rehydrated SN are cooking loss, elongation, hardness and adhesiveness/stickiness. Starch noodles have low of cooking loss but high hardness value, so it is less preferred. The purpose of this study was to obtain the optimum formulation of noodles made of sago with mung bean flour substitution. Formula optimization was done by using Mixture Design (DX7) with sago starch and mung bean flour as variables (80-100% and 0-20%; respectively). Mung bean flour substitution reduced hardness, adhesiveness and elongation of sago noodles, yet it increased the cooking loss. The best formulation based on physic-chemical characterization was SN with substitution of 4,7% mung bean flour. This sago noodles had 1996,03 gf hardness, -19,2 gf adhesiveness, 214,35% elongation and 10,82% cooking loss. Sensory test results for the most optimum formulation showed that the SN was not significantly different with those of commercial wheat noodle. Keywords: Cooking loss, elongasi, starch noodles, sago, mung bean flour   ABSTRAK Mi pati merupakan mi yang dibuat dari pati dan atau kombinasi tepung dari bahan non terigu. Bahan baku non-terigu indigenous Indonesia yang dapat digunakan untuk membuat mi pati adalah sagu. Karakteristik fisik yang sangat mempengaruhi kualitas mi setelah direhidrasi adalah cooking loss, elongasi, kekerasan dan kelengketan. Mi yang dibuat dari bahan dasar pati memiliki cooking loss yang rendah namun kekerasan yang tinggi, sehingga kurang disukai. Tujuan penelitian ini adalah mendapatkan formulasi optimum dari mi berbahan dasar sagu dengan substitusi tepung kacang hijau, sehingga dapat dihasilkan mi yang baik secara fisik dan diterima secara organoleptik. Optimasi formulasi dilakukan menggunakan Mixture Design (DX7) dengan variabel berupa persentase pati sagu (80-100%) dan tepung kacang hijau (0-20%). Substitusi tepung kacang hijau dapat menurunkan kekerasan, kelengketan, dan elongasi mi sagu, namun meningkatkan cooking loss. Produk optimum mi sagu diperoleh dengan substitusi tepung kacang hijau 4,7%. Pada kondisi ini mi sagu memiliki karakteristik kekerasan 1996,03 gf, skor kelengketan -19,2 gf, skor elongasi 214,35% dan skor cooking loss 10,82%. Uji sensori terhadap mi sagu formula optimum menunjukkan bahwa mi sagu yang dibuat secara keseluruhan tidak berbeda nyata dengan mi kering terigu komersial. Kata kunci: Cooking loss, elongasi, mi pati, sagu, tepung kacang hijau
