PENGARUH PERENDAMAN DALAM ASAM ORGANIK DAN METODA PENGERINGAN TERHADAP MUTU LADA HIJAU KERING

Nanan Nurdjannah, Hoerudin Hoerudin

Abstract


Dalam pembuatan lada hijau kering biasanya terjadi pencoklatan enzimatik yang menyebabkan hilangnya warna hijau sehingga membuat penampilannya menjadi tidak me-narik. Percobaan pencegahan reaksi pencok-latan dengan menggunakan asam sitrat, asam malat dan asam tartrat.pada pembuatan lada hijau kering telah dicobakan dengan perlakuan yang terdiri dari jenis asam (sitrat, malat dan tartrat), dengan 3 level konsentrasi (2, 3 dan 4%), serta 2 cara pengeringan (penjemuran dan oven). Percobaan dirancang secara Acak Leng-kap pola Faktorial dengan 2 ulangan. Hasil percobaan menunjukkan bahwa penggunaan asam sitrat, asam malat dan asam tartrat pada konsentrasi 2 persen, 3 persen dan 4 persen cukup efektif untuk mengurangi terjadinya reaksi pencoklatan enzimatik. Metode penge-ringan oven memberikan nilai kehijauan yang lebih baik dibandingkan dengan penjemuran. Hasil evaluasi sensori yang dilakukan pada atribut warna, rasa dan aroma lada hijau kering, menunjukkan bahwa produk yang dihasilkan dengan kombinasi perlakuan asam tartrat 2% dengan pengeringan oven lebih disukai dari-pada yang lainnya. Mayoritas parameter mutu lada hijau kering hasil penelitian telah meme-nuhi parameter mutu lada hijau kering yang tersedia di pasar.
