Optimasi Waktu Ekstraksi Lemak dengan Metode Soxhlet Menggunakan Perangkat Alat Mikro Soxhlet

Abstract

Lemak dan minyak terdapat pada hampir semua jenis bahan pangan dan masing-masing mempunyai jumlah kandungan yang berbeda-beda. Oleh karena itu analisis kadar lemak suatu bahan pangan sangat penting dilakukan untuk menghitung kalori suatu bahan makanan. Penentuan kadar lemak menggunakan metode Soxhlet memerlukan waktu ekstraksi antara 4 sampai 6 jam untuk mencapai 5 - 6 sirkulasi. Pada penelitian ini analisis lemak menggunakan perangkat alat ekstraksi mikro soxhlet sehingga untuk mencapai 1 kali sirkulasi membutuhkan waktu yang lebih pendek. Penelitian ini bertujuan untuk menentukan lama waktu ekstraksi sehingga analisis lemak dapat dilaksanakan dengan efektif dan efisien. Sampel yang dianalisis adalah jagung, kedelai dan wijen dengan variasi waktu ekstraksi selama 0,5; 1; 1,5; dan 2 jam, dibandingkan dengan 4 jam. Hasil menunjukkan bahwa analisa lemak sampel jagung memerlukan waktu selama 1 jam (3,62 ±0,05%), sampel kedelai memerlukan waktu 1,5 jam (19,40 ±0,11%) sedangkan untuk sampel wijen memerlukan waktu 2 jam (19,40 ±0,11%) untuk mendapatkan hasil yang sama dengan lama ekstraksi 4 jam. Lama ekstraksi lemak pada sampel bisa dilakukan selama 2 jam.
