Abstract
The present invention discloses a preparation method of stevia rebaudiana leaf and digitalis purpurea leaf tea powder. The stevia rebaudiana leaf and digitalis purpurea leaf tea powder is prepared from stevia rebaudiana leaves and digitalis purpurea leaves as raw materials, and prepared by raw material preparing, boiling, enzymolyzing, enzyme inactivating, filtering, crushing, mixing, homogenizing, spray drying, tidying and packaging, etc. The method uses the widely sourced, green and healthy stevia rebaudiana leaves and digitalis purpurea leaves as the raw materials, reduces costs, and also improves economic values and nutritional values of the stevia rebaudiana leaves and digitalis purpurea leaves. The stevia rebaudiana leaves and digitalis purpurea leaves are heated and boiled, boiled residues are subjected to a complex enzyme treatment, and a utilization of the stevia rebaudiana leaves and digitalis purpurea leaves is improved. The twice homogenizing improves a mouthfeel of a finished product of the double leaf tea powder, so that the finished product of the double leaf tea powder has health-care effects of lowering blood pressure, preventing tumors and diarrhea, improving immunity, promoting metabolism, etc.
Description
technical field [0001] The invention relates to a method for preparing tea powder, in particular to a method for preparing stevia digitalis double-leaf tea powder. Background technique [0002] Stevia leaf is a perennial herb of Compositae and Stevia. This species likes to grow in a warm and humid environment and is sensitive to light. The leaves contain 6-12% inulin, and the fine product is white powder. It is a low-calorie, high-sweet natural sweetener, and is one of the raw materials for the food and pharmaceutical industries. [0003] Digitalis leaves, also known as foxglove, poisonous herb, purple foxglove, bell flower, are native to the mountainous areas of central and southern Europe. Now China's Zhejiang, Shanghai, Jiangsu and Shandong have been cultivated in large quantities. It is better for chronic congestive heart failure with diastolic expansion of the heart chamber. At the same time, accompanied by atrial fibrillation is the best indication for the applicat...
