Problems solved by technology

But, the mode of making artichoke flower tea of ​​these patents all has very serious drawback, as CN201610510468 the water content of the artichoke flower tea that CN201610510468 makes is still at 8-10%, has a strong impact on the storage time of artichoke flower tea; Lead to the great loss of biologically active substances in the Jerusalem artichoke flower, especially the nutrients such as chlorogenic acid, protein and vitamin; Affecting the quality of Jerusalem artichoke tea
[0005] At present, the content of biologically active substances such as chlorogenic acid in Jerusalem artichoke flower tea produced according to the above patented technology or conventional methods is very low or basically no (chlorogenic acid is easily damaged by high temperature or microwave), and the nutrients such as protein and vitamins are seriously lost. Dark brown, bitter taste, chaotic flower shape, etc.

Abstract

The invention belongs to the technical field of health-care tea, and particularly discloses organic Helianthus tuberosus flower tea and a making method thereof. The making method comprises the steps of picking, cleaning, airing, ultraviolet radiation, pre-freezing, freeze-drying and the like, and the making method of the Helianthus tuberosus flower tea is determined on the basis of quantitative analysis of nutritional components and bioactive substances of the Helianthus tuberosus flower tea. Various treatment steps and treatment conditions in the preparation process are limited, and a freeze-drying process is adopted, so that the color, aroma and pattern of Helianthus tuberosus flowers can be kept, nutrient substances and bioactive substances in the Helianthus tuberosus flowers can be reserved to the greatest extent, and the Helianthus tuberosus flower tea with excellent color, aroma, taste and shape is obtained. The water content of the prepared Helianthus tuberosus flower tea is less than or equal to 5%, and the storage time is highly prolonged. Meanwhile, the effects of preventing cancer, resisting cancer, inhibiting bacteria, diminishing inflammation, reducing blood sugar, reducing blood pressure, reducing blood fat, resisting oxidation, resisting mutation, maintaining beauty, keeping young, conditioning complexion and the like are better maintained.

Description

technical field [0001] The invention belongs to the technical field of health-care tea processing, and in particular relates to an organic artichoke flower tea and a preparation method thereof. Background technique [0002] Jerusalem artichoke (Helianthus tuberosus Linn) is a perennial herbaceous plant of the genus Helianthus L. in the family Compositae, also known as Jerusalem artichoke. It is an ecological, extensive It is a type of economic crop, and there is no need for manual operations such as additional fertilization, spraying pesticides and deworming during the entire growth process of Jerusalem artichoke. Jerusalem artichoke can form stems rich in fructo-oligosaccharides underground, and the straw with high crude fiber content on the ground can be used as livestock feed. Jerusalem artichoke leaves are rich in biologically active substances; Different flowering periods vary, the longest can reach 120 days, and the shortest flowering period is about 20 days. Jerusal...
