The invention belongs to the technical field of tea leave processing and particularly relates to a processing process for low-caffeine high-aroma acrid-taste-free tea leaves. According to the processing process, picked fresh tea leaves are directly sprayed with hot water and treated in an enzyme solution spraying mode, under the damp and hot effect and the effect of an enzyme solution in the hot water soaking and hot air dewatering treatment links, ester catechin causing the heavy acrid taste of the tea leaves is reduced to a certain degree after hydrolysis, non-galloylated catechin with low acrid taste is increased, and therefore the acrid taste of the tea leaves is greatly relieved. The enzyme solution can promote generation of linalool, geraniol and other floral substances, aqueous extract, free amino acid and soluble sugar are increased, the free amino acid with high content and the soluble sugar with high content can form chestnut aroma substances in the high-temperature drying process, the aroma of the tea leaves is further improved, and the purposes of being high in aroma and free of the acrid taste are achieved.
