Abstract
[Objective] The research aimed to study the microwave-assisted extraction technics of paprika pigments and its stability.[Method] The capsanthin was extracted from paprika with organic solvents.The extraction rate was determined by single factor test under different microwave power,time,solid-liquid ratio,then the best extraction conditions were confirmed by orthogonal test.The physical properties of paprika pigments and its chemical stability were carried out.[Result] The best extraction conditions of paprika pigments were as follow:ethyl acetate as solvent,microwave power high,solid-liquid ratio 1∶9,microwave processing time 14 min.Comparing with the extraction,microwave extraction had greatly shortened the extraction time,and significantly improved the yield.The results of physical properties and chemical stability analysis of paprika pigments show that the paprika pigments is a stability natural red pigment and also suitable for adding in all types of products.[Conclusion] The study can provide scientific basis for extraction,application and color retention during processing.
