Abstract
|
|
|
|
Preservation of backseolgi by modified-atmosphere packaging (MAP) method for industrial production was evaluated with respect to shelf life and a prevalent flora was identified. Backseolgi was stored in low-density polyethylene (LDP), top-sealing package (TSP), and MAP packages. The number of microflora did not substantially change in all samples at 3°C for 30 days, but rapidly increased in LDP and TSP samples at 30°C. MAP was the most effective storage method. With DNA sequence analysis, it appeared that the predominant contaminant belonged to the genus Penicillium, and it was named Penicillium sp. DA.
