Abstract:

The effects of 80% oxygen modified atmosphere packaging on microbial populations and quality maintenance of
Agaricus bisporus were studied during cold storage at (5 ± 1) ℃. Results showed that during the process of storage, highoxygen
atmosphere could inhibit the growth of moulds and yeasts in Agaricus bisporus, and also had a significant inhibition
on the total number of Pseudomonas genus. In the early stage of the storage, high oxygen packaging could inhibit the
increase in the total number of mesophilic bacteria, but in the late storage instead promote its growth. Compared with control
groups, high-oxygen atmosphere packaging could maintain a high sugar content, inhibit the decline of ascorbic acid content,
and also maintain good sensory quality, but it had no significant effect on protein contents in Agaricus bisporus.
