Effect of aroma-enhancing technology on the physical and chemical quality of Huangbo Zen tea

To improve the aroma quality of Huangbo Zen tea, the effect of aroma-enhancing technology on the physical and chemical quality of Huangbo Zen tea was studied. The result of single factor test showed that the suitable temperature and time of aroma-enhancing were 100~120益and 10 min respectively. The result of orthogonal test showed that the physical and chemical of Huangbo Zen tea was the best when the leaf weight was 800 g, the aroma-enhancing temperature was 120益and the aroma-enhancing time was 10 min.
