The invention relates to the technical field of tea processing, in particular to a processing method of white tea rich in GABA (gamma-aminobutyric acid). The processing method comprises the following specific steps: seed selection: selecting a high-amino-acid tea tree variety; spraying: spraying a polyamino acid solution on leaf surfaces; anaerobic treatment: picking fresh white tea leaves, filling non-oxygen gas at normal temperature for sealing treatment, and performing intermittent coupling gamma ray irradiation; aerobic treatment: sealing treatment is carried out in an aerobic environment, and intermittent coupling gamma ray irradiation is carried out; the third step and the fourth step are cycled for 4-6 rounds; processing, carrying out microwave fixation, rolling and drying treatment to obtain the white tea rich in GABA. According to the preparation method disclosed by the invention, a large amount of glutamic acid in the tea leaves can be converted into GABA (gamma-aminobutyric acid), so that the obtai
