Abstract
[Objective] The aim was to study the improvement of the extraction process of red pigment from rose and its application.[Method] The freezing-thawing and grinding combined method was added to break up the cells before extraction,and the improved technology was compared with the old one.[Result] The results showed that the extraction amount was increased by 24.50% with the improved process,and the improved process was simple and practical.The red pigment showed different colors in different pH values.Finally,rose red pigment was added into wine,vinegar and beverage to make characteristic rose series products which were stable in quality.[Conclusion]The study provides a basis for further development and exploitation of the natural rose red pigment.
