Embodiment 1

[0021] 1) Take 50 kg of summer and autumn green tea and perform rehydration treatment (spray drinking water on the surface of the tea leaves to allow them to fully absorb), so that the moisture content of the tea leaves reaches 15%;

[0022] 2) 5 kg of apples, 4 kg of fresh tea leaves and 3 kg of water were mixed and squeezed for juice, and filtered to obtain mixed fruit tea juice;

[0023] 3) Mix the rehydrated summer and autumn tea with the fruit tea juice and mix well. The amount of fruit tea juice added is 30% of the weight of the rehydrated summer and autumn tea. The kneaded leaves are fermented according to the black tea fermentation process, and 1.5 g of tannin is added to the fermented leaves Enzyme (0.003% of the weight of summer and autumn tea) is processed until the fermented leaves have obvious black tea fruity aroma;

[0024] 4) After the fermentation, the fermented leaves were dried in a dryer at 110°C for 50 minutes, then at 85°C for 100 minutes to obtain black ...

Embodiment 2

[0028] 1) Take 50 kg of summer and autumn tea (20 kg of green tea + 30 kg of oolong tea), and perform rehydration treatment (spray drinking water on the surface of the tea leaves to allow them to fully absorb), so that the moisture content of the tea leaves reaches 30%;

[0029] 2) 5 kg of pears, 6 kg of fresh tea leaves and 2 kg of water were mixed and squeezed for juice, and filtered to obtain mixed fruit tea juice;

[0030] 3) Mix the rehydrated summer and autumn tea with the fruit tea juice and mix well. The amount of fruit tea juice added is 10% of the weight of the rehydrated summer and autumn tea. The kneaded leaves are fermented according to the black tea fermentation process, and 3.5 g of tannin is added to the fermented leaves Enzyme (0.007% of the weight of summer and autumn tea) is processed until the fermented leaves have obvious black tea fruity aroma;

[0031] 4) After the fermentation, the fermented leaves were dried in a dryer at 120°C for 30 minutes, then at ...

Embodiment 3

[0035] 1) Take 50 kg of summer and autumn tea (10 kg of green tea + 20 kg of oolong tea + 20 kg of yellow tea), and perform rehydration treatment (spray drinking water on the surface of the tea leaves to allow them to fully absorb), so that the moisture content of the tea leaves reaches 20%;

[0036] 2) 3 kg of apples, 4 kg of pears, 6 kg of fresh tea leaves and 6 kg of water were mixed and squeezed for juice, and filtered to obtain mixed fruit tea juice;

[0037] 3) Mix the rehydrated summer and autumn tea with the fruit tea juice and mix well. The amount of fruit tea juice added is 10% of the weight of the rehydrated summer and autumn tea. The kneaded leaves are fermented according to the black tea fermentation process, and 6.5 g of tannin is added to the fermented leaves Enzyme (0.013% of the weight of summer and autumn tea) is processed until the fermented leaves have obvious black tea fruity aroma;

[0038] 4) After the fermentation, the fermented leaves were dried in a d...

Abstract

Belonging to the technical field of fruit flavor tea processing methods, the invention relates to a processing method of a fruit flavor black tea. The method includes the steps of: conducting rehydration treatment on summer and autumn tea to make the tea moisture content reach 15-35%; mixing fruits, fresh tea leaves and water, then conducting juicing treatment, and performing filtering to obtain mixed fruit tea juice; mixing the rehydrated summer and autumn tea with the mixed fruit tea juice, blending them evenly, subjecting the rolled leaves to fermentation according to a black tea fermentation process, and adding tannase to conduct treatment during fermentation until the fermented leaves generate obvious black tea fruit fragrance; and at the end of fermentation, placing the fermented leaves into a dryer for drying, thus obtaining the sweet fruit flavor black tea. The method provided by the invention utilizes the currently abundant medium-low grade tea resources and fruits to produce natural fruit flavor black tea in non-tea producing areas and non-tea producing seasons, and is more beneficial to industrial production. The provided fruit flavor black tea has the characteristics of dark red appearance, brilliant red and bright soup, strong sweet fruit flavor, sweet, mellow and refreshing taste, high nutritional value, no limit of tea raw materials, and stable product quality.
