Pengaruh penerapan teknologi vakum dan non-vakum terhadap umur simpan pangan berminyak

Abstract

Research about the application of vaccum and non vacuum technology for the storage of greasy food using two types of polyethylene (0. Mm) and bilayer (polyethylene and nylon 0.09 mm) was carried out. The objective of the research was to know the influence of packaging for technology storage of greasy foods (sambel pecel). The result showed that water vapour permeability of bilayer was lower than of polyethylene and the score was 1.72 mg/24 hours for polyethylene and 1.58 mg/24 hours bilayer. Water activity (aw) after 60 days storage was 0.43-0.56. while the score of peroxide value of greasy foods packed using non vacuum technology was 10.18-24.98 mg Fe2+ and the score of greasy foods (sambel pecel) using vacuum technology was 10.18-17.48 mg Fe2+ and the score of greasy foods (sambel pecel) using vacuum technology was 10.18-17.48 mg Fe2. Sensories evaluation of greasy foods indicated with bilayer and vacuum technology gave high score.
