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.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
