Abstract
INDONESIA
Pulse Electric Field (PEF) merupakan teknologi fisik yang didasarkan pada tenaga elektronik yang dilakukan pada suhu rendah atau sedang. PEF dapat mewakili teknologi pengawetan pangan alternatif nontermal dalam upaya menjaga kualitas bahan pangan. Teknologi PEF ini bertujuan untuk mengetahui kadar lemak dan kadar air suatu bahan. Bahan penelitian yang digunakan adalah daging sapi. Pengaturan alat PEF menggunakan variasi frekuensi antara 20 Hertz, 40 Hertz, 60 Hertz, 80 Hertz, 100 Hertz pada waktu tetap selama 25 menit, sementara variasi waktu antara 15 menit, 20 menit, 25 menit, 30 menit pada frekuensi tetap sebesar 100 Hertz. Hasilnya, kandungan lemak pada daging sapi tidak mengalami penurunan terhadap variasi frekuensi ataupun waktu, sementara kandungan air pada daging sapi mengalami penurunan maksimum terhadap variasi frekuensi senilai 4,511 gram dan penurunan maksimum terhadap variasi waktu senilai 4,680 gram.
ENGLISH
Pulse Electric Field (PEF) is a physical technology based on electronic power that is carried out at low or medium temperatures. PEF can represent non-thermal alternative food preservation technology in the effort to maintain the quality of food ingredients. The PEF technology aims to determine the level of fat and moisture content of an ingredient. The research material used is beef. The PEF tool settings use the variation of frequency: 20 Hertz, 40 Hertz, 60 Hertz, 80 Hertz, 100 Hertz at a fixed time of 25 minutes, while the variation of time was 15 minutes, 20 minutes, 25 minutes, 30 minutes at a fixed frequency of 100 Hertz. As a result, the fat content in the beef has not decrease in the variation of frequency or time, while the water content in the beef has decreased the maximum frequency variation of 4.511 grams and the maximum decrease to a variation of time worth 4.680 grams.
