摘要: 以牛油火锅底料为研究对象,在不同贮藏温度(5、25、37℃)条件,对牛油火锅底料的感官品质、酸价、过氧化值及菌落总数变化情况进行研究。结果表明预测牛油火锅底料货架期采用酸价变化动力学模型较为可靠。以酸价为指标建立动力学模型预测牛油火锅底料的货架期,模型的活化能(E)和回归系数(K0)分别为21.82J/mol和32.62。经验证,此动力学模型可较准确的预测火锅底料货架期。

Abstract: In this study, we investigated changes in the sensory quality, acid value, peroxide value and total bacterial count of butter hotpot seasoning during storage at different temperatures (5, 25 ℃ and 37 ℃). Acid value was found to be a reliable indicator for predicting the shelf life of butter hotpot seasoning. A kinetic model of acid value for predicting the shelf life of butter hotpot seasoning was developed with E (activation energy) and K0 (regression coefficient) of 21.82 J/mol and 32.62, respectively. The reliability of the prediction model was validated.

Key words: butter hotpot seasoning, shelf life, temperature, kinetic model
