Embodiment 1

[0023] 1) Softening water extraction: Soften cooked Puer tea by steaming at 80°C for 20 minutes, add the softened tea leaves to 40°C hot water, the amount of hot water added is 12 times the weight of the tea leaves, and then the hot water circulates for a period of time for 40min.

[0024] 2) Filtration: After the liquid in step 1) is pre-filtered, it is filtered again through an ultrafiltration membrane to obtain a filtrate.

[0025] 3) Extraction and enzymatic hydrolysis: send the filtrate cooled to 10°C into a rotary distillation tower for extraction, and add immobilized tannase at 1% of the filtrate mass during extraction.

[0026] 4) Add inhibitory protein: add white kidney bean α-amylase inhibitory protein to the tea liquid in step 3) according to 10% of the weight of the filtrate, and stir to completely dissolve the added white kidney bean α-amylase inhibitory protein.

[0027] 5) Concentration: use reverse osmosis membrane to concentrate the additive liquid in step 4)...

Embodiment 2

[0030] 1) Softening water extraction: Soften raw Puer tea by steaming at 110°C for 25 minutes, add the softened tea leaves to 42°C hot water, the amount of hot water added is 13 times the weight of the tea leaves, and then the hot water circulates for a period of time for 50min.

[0031] 2) Filtration: After the liquid in step 1) is pre-filtered, it is filtered again through an ultrafiltration membrane to obtain a filtrate.

[0032] 3) Extraction and enzymatic hydrolysis: send the filtrate cooled to 20°C into a rotary distillation tower for extraction, and add immobilized tannase with a mass of 1.2% of the filtrate during extraction.

[0033] 4) Add inhibitory protein: Add white kidney bean α-amylase inhibitory protein to the tea liquid in step 3) according to 15% of the weight of the filtrate, and stir to completely dissolve the added white kidney bean α-amylase inhibitory protein.

[0034] 5) Concentration: use reverse osmosis membrane to concentrate the additive liquid in ...

Embodiment 3

[0037] 1) Softening water extraction: Soften ripe Puer tea or raw Puer tea by steaming at 120°C for 35 minutes, add the softened tea leaves to 45°C hot water, the amount of hot water added is 15 times the weight of the tea leaves, and then heat Water circulation, time is 60min.

[0038] 2) Filtration: After the liquid in step 1) is pre-filtered, it is filtered again through an ultrafiltration membrane to obtain a filtrate.

[0039] 3) Extraction and enzymatic hydrolysis: send the filtrate cooled to 25°C into a rotary distillation tower for extraction, and add immobilized tannase with a mass of 1.5% of the filtrate during extraction.

[0040] 4) Add inhibitory protein: add white kidney bean α-amylase inhibitory protein to the tea liquid in step 3) according to 20% of the weight of the filtrate, and stir to completely dissolve the added white kidney bean α-amylase inhibitory protein.

[0041] 5) Concentration: use reverse osmosis membrane to concentrate the additive liquid in s...

Abstract

The invention relates to a production technology of fat-reducing Puer tea. The production technology of the fat-reducing Puer tea comprises the following steps: (1) conducting samming and water-extraction; (2) conducting filtering; (3) conducting extraction and enzymolysis; (4) adding inhibiting protein; (5) conducting concentration; and (6) conducting drying. By using the white kidney bean alpha-amylase inhibiting protein in combination for production of Puer tea, the fat-reducing Puer tea, which can be quickly brewed, with a Puer tea aroma and efficacy of reducing decomposition and conversion into sugar of starch at the same time is obtained with the efficacy of the Puer tea of assisting in reducing blood lipids kept.

Description

technical field [0001] The invention belongs to the technical field of tea preparation, and in particular relates to a preparation process of Pu'er slimming tea. Background technique [0002] Tea is a traditional beverage raw material with a broad mass base. Tea leaves are processed from the tender buds of the fresh tea tree that are picked raw. Tea is one of the world's three major beverages and is known as the "Emperor of Oriental beverages". Dark tea is one of the six major teas in my country. Puer tea is dark tea, which is loose tea and pressed tea made from Yunnan big-leaf sun-dried green tea as raw material and post-fermented. The appearance is brownish red, the inner soup is red and bright, the aroma is unique and fragrant, the taste is mellow and sweet, and the bottom of the leaves is brownish red. The tea polyphenols in Puer tea have the effect of reducing blood lipids. [0003] According to the China Health Report, there are currently about 300 million obese peo...
