摘要: 从霉变的牛肉干上分离出一株霉菌,经鉴定为曲霉。通过将该曲霉接种到牛肉干上并在不同的水分活度条件下培养来研究牛肉干水分活度和保质期的关系。实验结果证明,牛肉干的保质期与其水分活度有密切的相关性。

Abstract: A mold was isolated from mildewed dried beef and it was identified as an Aspergillus.This Aspergillus was then inoculated into the dried beef to determine the influence of water activity to the shelf life.The results showed that the water activity of dried beef was essential to its shelf life.

Key words: Aspergillus, dried beef, intermediate-moisture foods, water activity, shelf life
