Embodiment 1
[0035] A method for preparing cornus officinalis solid drink, comprising the following steps:
[0036] (1) Preparation of dry fruit powder of Cornus officinalis: the cleaned mature fruit of Cornus officinalis was heated by microwave at a microwave power of 300W for 1 min, followed by denucleation treatment, and the denucleated fruit pulp of Cornus officinalis was placed in a blast drying box, Baking at 40°C for 10 hours to obtain dried pulp, crushing the dried pulp and passing it through a 40-mesh sieve to obtain dry fruit powder of Cornus officinalis.
[0037] (2) Preparation of water extract granules of Cornus officinalis: Mix dry fruit powder of Cornus officinalis, citric acid, acetone and deionized water according to a certain weight ratio, and conduct ultrasonic extraction at 25°C for 15 minutes, with ultrasonic power of 300w, and every 3s of ultrasound with an interval of 2s. Ultrasonic extraction once, after the end of ultrasound, filter to obtain the water extraction fil...
