SUBSTITUSI TEPUNG SUKUN SEBAGAI SUMBER SERAT UNTUK PENINGKATAN KUALITAS FLACKY CRACKERS
Sari
Flaky crackers adalah crackers dengan tekstur berlapis. Penggunaan terigu dapat digantikan dengan tepung sukun untuk meningkatkan kualitas crackers. Tepung sukun memiliki kandungan serat 8,06 %. Penelitian ini bertujuan untuk peningkatan kualitas fisik, kimia dan mikrobiologis flaky crackers dengan adanya substitusi tepung sukun. Rancangan Acak Lengkap (RAL) menggunakan 4 variasi terigu dan tepung sukun yaitu 100:0 (K), 90:10 (A), 80:20 (B), 70:30 (C). Hasil penelitian menunjukkan bahwa adanya pengaruh terhadap uji kimia, warna, tekstur, serta uji mikrobiologi yaitu meliputi perhitungan angka lempeng total (ALT) dan angka kapang khamir setelah dilakukan substitusi tepung sukun pada flaky crackers. Produk flaky crackers perlakuan 80:20 (B) menghasilkan kualitas paling baik dengan kadar air 5,35 %, abu 2,52 %, protein 8,41 %, serat tidak larut 0,48 %, serat larut 1,20 %, angka lempeng total 3,72 log koloni/gram dan angka kapang khamir 1,43 log koloni/gram.
