文摘

Impact of thermal treatment on β-LG-carotenoids was investigated. An increase in intrinsic and extrinsic fluorescence intensity of complex up to 90 °C was suggested. Blue-shifts in λmax at lower temperature and red-shifts at higher temperature were found. The unfolding of protein at higher temperature was suggested. High temperature caused important changes in the β-carotene binding site.
