Dian Histifarina, Darkam Musaddad, E. Murtiningsih

Abstract


Tujuan penelitian untuk mengkaji pengaruh suhu dan lama pengeringan terhadap karakteristik mutu sayuran wortel
kering. Penelitian dilakukan di Laboratorium Fisiologi Hasil Balai Penelitian Tanaman Sayuran di Lembang dari
bulan Juli sampai Oktober 2000. Rancangan percobaan yang digunakan adalah acak kelompok pola faktorial dengan
tiga ulangan dan dua faktor. Faktor pertama adalah suhu pengeringan (40, 50, dan 60°C) dan faktor kedua adalah lama
pengeringan (17, 22, 27, dan 32 jam). Hasil penelitian menunjukkan bahwa perlakuan lama pengeringan 32 jam yang
dikombinasikan dengan suhu pengeringan 50°C menghasilkan wortel kering terbaik berdasarkan nilai kadar air
(9,15% bb), kadar beta karoten (0,019%), persentase rehidrasi tinggi (520,44%), dan penilaian sensori terhadap warna
serta tekstur yang baik.
