Study on Effect of Three Kinds of Spices on Organic Acids During the Fermentation of Ciba Pepper
In order to explore the effects of three kinds of spices(garlic,ginger and Zanthoxylum bungeanum)on the production of organic acids during the fermentation of Ciba pepper,in this study,the spices(garlic,ginger and Zanthoxylum bungeanum)are added respectively into Ciba pepper for 35 days of fermentation.The change trend of six organic acids(tartaric acid,malic acid,lactic acid,acetic acid,citric acid and succinic acid)during the fermentation of Ciba pepper are analyzed by high performance liquid chromatography(HPLC).The results show that the overall pH of Ciba pepper shows a downward trend during the fermentation process,and the content of total acids show an upward trend.At the end of fermentation,the order of pH is HJ＜SJ＜DS＜CK,and the order of the content of total acids is DS=CK＜SJ＜HJ.Liquid chromatography analysis shows that there are significant differences in the content of organic acids among the four kinds of Ciba peppers(P＜0.05)during the whole fermentation process.Malic acid is the main organic acid of the four kinds of Ciba peppers.At the initial stage of fermetation,the proportion of malic acids to total organic acids is CK 33％,DS 48％,SJ 26％,HJ 28％.At the end of fermentation,the proportion is CK 53％,DS 46％,SJ 51％,HJ 48％.The results of electronic tongue show that the addition of a certain proportion of garlic,ginger and Zanthoxylum bungeanum into the fermented Ciba pepper has a certain effect on its taste characteristics,and HJ has greater values on the sourness and umami sensors.The addition of garlic,ginger and Zanthoxylum bungeanum increases the total amount of organic acids in the fermentation process of Ciba pepper,among which,ginger is beneficial to the production of tartaric acid,malic acid,lactic acid and succinic acid,while Zanthoxylum bungeanum is beneficial to the production of malic acid,lactic acid and citric acid.This study has provided a theoretical basis for the industrial production of fermented Ciba pepper.
