Abstract
Summary A modified‐atmosphere packaging system for chilled fresh potato strips, which rapidly produced oxygen levels < 3%, was identified. This system enclosed the strips within 25 μ low density polyethylene film heat sealed to a fibre tray lined with Surlyn‐PVdC‐Surlyn, and the package flushed with an initial atmosphere of 5% O 2 , 10% CO 2 . An equilibrium‐modified atmosphere of 3–4% CO 2 , 1–2% O 2 was established after 3 days' storage at 5°C. This modified‐atmosphere package, used in combination with dipping of potato strips in a 10% ascorbic acid solution, inhibited enzymatic discoloration for 1 week at 5°C. Vacuum packaging within a Surlyn/PVdC‐coated polyester film, with or without dipping in ascorbic acid solution, inhibited discoloration of chilled potato strips stored at 5°C for at least 2 weeks.
