Decision method for fermentation degree and fermentation stop status of fermented tea materials

摘要

The present invention relates to a method for determining whether fermentation of a fermented tea material is stopped or not by determining the degree of fermentation using the difference between the redness and yellowness of the fermented tea material during the fermentation process of the fermented tea, A method for determining whether to stop fermentation of a fermented tea material according to the present invention is a method for fermentation of a desired fermented tea regardless of the type of fermented tea material, The fermented tea product of the present invention can be used to produce a fermented tea product having a constant quality and flavor suitable for consumers' taste. The method of manufacturing a fermented tea according to the present invention is characterized in that the redness and yellowness of a fermented tea material are measured during the fermentation process of the fermented tea to determine the fermentation degree of the fermented tea material according to the degree of fermentation, It is possible to provide a fermented tea having a constant quality. In addition, since the fermentation stop point of the desired fermentation tea can be accurately predicted during the processing before the fermentation tea is processed, the manufacturing time and cost of the fermentation tea can be reduced.;
