Comprehensive evaluation of different vinegar preparation methods of Cornus officinalis based on entropy weight-TOPSIS model
Objective To establish a comprehensive evaluation model based on entropy weight-TOPSIS,and the contents of 5-hydroxymethylfurfural(5-HMF),monoside and maggianin were used as indicators to explore the optimal vinegar preparation method of Cornus officinalis,so as to lay a foundation for the processing of Cornus officinalis.Methods Cornus officinalis was processed by three different ways:atmospheric vinegar steaming,pressure vinegar steaming and vinegar stewing.The contents of 5-HMF,monoside and maggianin were determined by HLPC,and the above three contents were used as evaluation indexes.The method was comprehensively analyzed and evaluated by using entropy weight-TOPSIS model.Results After the analysis of entropy weight-TOPSIS model,the relative proximity of Cornus officinalis stewed with vinegar,steamed with pressure vinegar and steamed with normal pressure vinegar were 0.449,0.247 and 0.613,respectively.Among the three methods of vinegar preparation,normal pressure vinegar steamed Cornus officinalis was the best,vinegar stewed Cornus officinalis was the second,and pressure vinegar steamed Cornus officinalis was the worst.Conclusion Based on the analysis of the comprehensive evaluation model of entropy weight-TOPSIS,the optimal vinegar preparation method is atmospheric pressure vinegar steaming,which provides a basis for the processing of traditional Chinese medicine.
