fish, porang, pempekAbstract
Porang tuber is one of Indonesia's local foods with high glucomannan content. Glucomannan is a type of soluble fiber that can strengthen myofibril gels which gives it potential usage in gel food such as pempek. This research is aimed to know the effect of the ratio between tapioca flour and porang flour (90:10, 80:20, dan 70:30) and concentration of fish (32.5%, 37.5%, dan 42.5%). The result showed that increasing fish concentration has a trend to also increase the springiness and scoring value of rubberiness. Increase in porang flour used cause pempek’s colour to change into more brown and lower lightness. The best formulations which is 42.5% fish concentration and tapioca flour:porang flour ratio of 90:10 has springiness of 0.92 ± 0.02, overall acceptance of 4.85 ± 1.26, moisture content of 67.32 ± 4.44%, and protein content of 5,10 ± 0,88%.
Bahasa Indonesia Abstract:
Umbi porang merupakan pangan lokal Indonesia yang memiliki kandungan glukomanan yang tinggi. Glukomanan merupakan serat larut yang dapat memperkuat gel miofibril sehingga dapat diaplikasikan pada produk olahan seperti pempek. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh rasio tepung tapioka dan tepung porang (90:10, 80:20, dan 70:30) dan perbedaan konsentrasi ikan tenggiri (32,5%, 37,5%, dan 42,5%) terhadap karakteristik fisik dan sensori pempek lenjer. Hasil penelitian menunjukkan peningkatan konsentrasi ikan cenderung meningkatkan springiness dan nilai skoring kekenyalan dari pempek. Peningkatan jumlah tepung porang yang digunakan menyebabkan warna dari pempek semakin coklat dan lightness menjadi semakin rendah. Karakteristik pempek terbaik diperoleh dari formulasi konsentrasi ikan 42,5% dan rasio tepung 90:10 dengan springiness sebesar 0,92 ± 0,02 dan penerimaan keseluruhan sebesar 4,85 ± 1,26 serta memiliki kadar air sebesar 67,32 ± 4,44% dan kadar protein sebesar 5,10 ± 0,88%.
