Embodiment 1
[0035] The steps of a kind of discoloration rose tea preparation method of the present embodiment are as follows:
[0036] Select a raw material rich in anthocyanins, pigments and polyphenols, clean it in the early stage, put it into a 10L three-dimensional pulverizer, and put it into 40% alcohol to extract the anthocyanins and polyphenols in the raw material Phenol and pigment were stirred at 5000rpm for 1h, then filtered with two layers of 600-mesh gauze, and kept for later use. The pre-filtered solution was naturally settled for 1.5 hours, the bottom residue was discarded, and then centrifuged at 6000 rpm for 15 minutes, and then the solution was concentrated in a heating plate at 100°C for 1.5 hours. After the concentrated solution was naturally cooled, it was centrifuged with a centrifuge at 6000 rpm for 15 minutes, 2% alcohol was added, and it was reserved for later use. Choose 500 roses after microwave drying, put them into the above concentrated solution, soak for 15 ...
Embodiment 2
[0038]Select a raw material rich in anthocyanins, pigments and polyphenols, clean it in the early stage, put it into an 8L three-dimensional pulverizer, and put it into 30% alcohol to extract the anthocyanins and polyphenols in the raw material Phenol and pigment were stirred at 4000rpm for 1.5h, then filtered with two layers of 600-mesh gauze, and kept for later use. The pre-filtered solution was naturally settled for 1 hour, the bottom residue was discarded, and then centrifuged at 5000 rpm for 10 minutes, and then the solution was concentrated in a heating plate at 90°C for 1.5 hours. After the concentrated solution was naturally cooled, it was centrifuged with a centrifuge at 6000rpm for 15 minutes, and 5% alcohol was added, and it was reserved for later use. Select 1,000 roses after microwave drying, put them into the above concentrated solution, soak for 10 minutes, take them out and shake them, then add a compound protease (neutral protease and trypsin) with a ratio of ...
Embodiment 3
[0040] Select a raw material rich in anthocyanins, pigments and polyphenols, clean it in the early stage, put it into a 10L three-dimensional pulverizer, and put it into 60% alcohol to extract the anthocyanins and polyphenols in the raw material Phenol and pigment were stirred at 5000rpm for 1h, then filtered with two layers of 600-mesh gauze, and kept for later use. The pre-filtered solution was naturally settled for 1.5 hours, the bottom residue was discarded, and then centrifuged at a speed of 5000 rpm for 10 minutes, and then the solution was concentrated in a heating plate at 100°C for 3 hours. After the concentrated solution was naturally cooled, it was centrifuged with a centrifuge at 5000 rpm for 15 minutes, 10% alcohol was added, and it was reserved for later use. Choose 500 roses after microwave drying, put them into the above concentrated solution, soak for 20 minutes, take them out and shake them, then add a compound protease (neutral protease and trypsin) with a r...
