PENGARUH LAMA PERENDAMAN DALAM LARUTAN NACL DAN LAMA PENGERINGAN TERHADAP MUTU TEPUNG TALAS BELITUNG (Xanthosoma sagittifolium)

Abstract: ABSTRACT The purpose of this study was to determine the effect of NaCl soaking time and drying time on the quality of belitung taro flour (Xanthosoma sagittifolium). This study used a factorial design using 2 factors: NaCl soaking time (0, 30, and 60 minutes) and drying time (3, 4 and 5 hours) consisting of 9 treatments and 3 replications. The parameters observed included chemical parameters (moisture, ash, starch, calcium oxalate, and crude fiber content) and physical parameters (yield, bulk density and… Show more

“…According to Wulansari et al [7], areca nut contains tannin compound that can be used as a natural red colour in food. The tannin content in areca nut reaches 6.45% by water solvent extraction and 8.53% by ethanol solvent extraction [8]. According to its colour properties and abundant source in Indonesia, tannin extracted from areca nut has a great potential to be applied as colorimetric indicator compound in smart packaging for food products.…”

“…The density value is influenced by the moisture content, particle size, and powder porosity [38]. Food that has a high bulk density shows a high nutrient density [39]. For example, corncobs powder with different drying times has an ash content ranging from 0.61-0.65 g/cm 3 .…”

“…Hasil yang diperoleh (Tabel 4) menunjukkan bahwa terjadi peningkatan serat kasar setelah diberi perlakuan dibandingkan dengan umbi talas segar. Hal ini sesuai dengan beberapa penelitian sebelumnya yaitu Wahidah (2017), menyatakan bahwa kandungan serat pada talas segar yaitu 0,7 g dan setelah perlakuan perebusan kandungan serat pada talas meningkat sebanyak 0,9 g. Menurut Suharti et al (2018), talas kimpul yang dijadikan tepung mengandung serat kasar yang tinggi seiring waktu pengeringan yang semakin lama. Hal ini disebabkan karena kadar air semakin banyak teruapkan sehingga serat kasar akan lebih terkonsentrasi.…”

“…Hasil ini sesuai dengan beberapa peneliti sebelumnya. Penelitian Agustin et al ( 2017) menyatakan bahwa perlakuan perendaman dengan asam asetat 20% selama 30 menit terjadi penurunan kalsium oksalat tertinggi pada talas kimpul yaitu 4,43 mg/100 g. Menurut Suharti et al (2018) kadar kalsium oksalat terendah diperoleh pada perlakuan perendaman dengan NaCl selama 60 menit dan pengeringan selama 5 jam pada suhu 60 o C yaitu 3,37 mg/100 g. Diketahui bahwa semakin lama perendaman dalam larutan NaCl dan dilanjutkan dengan pengeringan terjadi penurunan kadar oksalat pada talas Belitung. Perlakuan tersebut menyebabkan kalsium oksalat dapat direduksi dari umbi.…”
