ABSTRACT


The study was to determine the effect of the composition of modified atmosphere and the type
of packaging material on physico-chemical properties and sensory quality of minimally
processed coleslaw mix stored for 12 days at 4°C. Samples were
packaged in Flow HB 50 EZ Peel (OPP/PEEVOH) film with oxygen permeability of
3 cm3/m2/24 h or in Opalen 55 AF (OPA/PE) film with oxygen
permeability of 35 cm3/m2/24 h, with and without microperforation.
Tested vegetable salads were packaged in air atmosphere or in modified atmosphere
with an O2/CO2 percentage ratio of 70/30 and 80/20. It results from conducted analyses that the application of Opalen 55 AF 50 film (with oxygen permeability of 35 cm3/m2/24 h) with 2 x 10 microperforation
and modified atmosphere containing 70%O2/30%CO2 and 80%O2/20%CO2 makes
it possible to maintain good sensory quality of coleslaw mix during 12-day storage
at 4°C. In all analyzed samples a significant decrease (p ≤ 0.05) of solids
content was recorded during storage. After 12 days pH in samples packaged in
modified atmosphere, irrespective of the applied type of film, was significantly
(p ≤ 0.05) lower that in air atmosphere packaged vegetable salads.

Key words: coleslaw mix, modified atmosphere, packaging film.
