A shelf life prediction method for butter based on the effects of β-carotene on colour and oxidative stability
Abstract
This study aimed to examine the impact of β-carotene, astaxanthin and phytosterol esters on the colour and oxidative stability of butter, as well as to explore a shelf life prediction method based on colour analysis. The results of correlation analysis indicated a significant linear correlation between acidity and whiteness index and yellowness index, with a linear fit coefficient (r2) exceeding 0.9796. In comparison with traditional shelf life prediction models, this method exhibited an average deviation of only 6.9% in its predicted results. The findings may contribute to the rapid evaluation of the shelf lives of commercial butter products.
