Abstract

Pengemasan secara atmosfir termodifikasi (MAP) pada penyimpanan dingin merupakan cara yang tepat untuk menjaga kualitas dan kesegaran produk yang diolah secara minimal. Tujuan dari penelitian ini adalah untuk mengkaji pengaruh suhu terhadap permeabilitas gas pada plastik film untuk pengemasan secara atmosfir termodifikasi pada produk olahan minimal. Plastik film jenis polietilen stretch (ketebalan 10 mm) dan polipropilen (ketebalan 10 mm) digunakan dalam penelitian ini. Permeabilitas gas plastik film terhadap gas O₂ dan CO₂ dianalisis menggunakan kromatografi gas HP 5890 pada suhu 5, 10, 15, 20, dan 25 ^oC berdasarkan metode konsentrasi meningkat kondisi stabil. Hasil penelitian menunjukkan bahwa permeabilitas gas meningkat dengan meningkatnya suhu penyimpanan. Model persamaan Arrhenius mampu menggambarkan pengaruh suhu terhadap permeabilitas gas sangat baik dengan nilai koefisien determinasi (R²) berkisar antara 0.9586 dan 0.9943.

Kata kunci: permeabilitas gas, film polimer, modifikasi kemasan atmosfer, pengolahan minimal.
