Pengaruh blansing dan perendaman asam sitrat terhadap mutu fisik dan kandungan gizi tepung buah pandan tikar (Pandanus tectorius Park.)

Abstract

Kendala utama dalam pembuatan tepung buah pandan tikar (Pandanus tectorius Park.) adalah reaksi pencoklatan enzimatis selama proses pengirisan dan pengeringan, akibat adanya kontak dengan oksigen. Keadaan ini dapat dikurangi dengan perlakuan fisik dan kimiawi. Penelitian ini bertujuan untuk menentukan pengaruh blansing dan perendaman asam sitrat terhadap mutu fisik dan komposisi gizi tepung buah pandan tikar. Perlakukan yang digunakan dalam penelitian ini adalah blansing (dikukus pada 80oC, 3 menit), dan perendaman dalam asam sitrat (2%, b/v). Hasil penelitian ini menunjukkan bahwa perlakuan blansing dapat mencegah terjadinya reaksi pencoklatan enzimatis dibandingkan perendaman dengan daging buah asam sitrat pada tepung pandan tikar yang dihasilkan; dengan nilai rendemen (16,21%), tingkat kecerahan - nilai L (76,29), tingkat kemerahan - nilai a (2,41), tingkat kekuningan - nilai b (25,82), suhu gelatinisasi (92,33 oC), kelarutan dalam air (53,43%); serta mengandung air (10,08% bb), abu (10,00% bk), protein (5,73% bk), lemak (2,24% bk), karbohidrat (82,03% bk), serat kasar (24,42% bk) dan total gula (26,00% bk).
