The invention relates to a method for preparing orange peel tea, comprising the following steps: 1) selecting matured Xinhui citrus reticulata 'Chachigan' fruit with complete peels, washing the fruit to be clean, peeling, removing
flesh, putting the peels in a sunny place for
drying, storing the orange peels under sealed condition after
drying treatment, and then
softening the orange peels; 2) sterilizing the softened orange peels by
ozone and then disinsectizing at high temperature; 3) humidifying the orange peels obtained in step 2) for 7-8 hours by using moist air with
humidity of 60-80% for further
softening, and then pressing the orange peels for forming; 4) performing
drying treatment and storing the orange peels under sealed condition for 2-5 months for primary
fermentation, removing the orange peel tea after primary
fermentation, humidifying for 5-6 hours by using moist air with the
humidity of 60-80%, and then drying in a sunny place; 5) collecting the dried orange peel tea and then putting the dried orange peel tea in dry air with
humidity of 30-50% for 4-5 hours for heat reduction; and 6) storing the treated orange peel tea under sealed condition again for natural
fermentation. The orange peel tea fundamentally has no
pesticide residue after several years of production, fermentation and aging, thus being a pure nature environment-friendly green health-care food.
