Description

Technical Field

[0001] The invention relates to the technical field of preparation of dendrobium officinale flower tea, in particular to a preparation process of dendrobium officinale flower tea with the function of lowering blood lipids. Background Art

[0002] Dendrobium candidum belongs to the orchid family, and its flowers are yellow-green. Modern medical research has confirmed that the medicinal ingredients of Dendrobium candidum mainly include dendrobium polysaccharides, dendrobium alkaloids and amino acids, which have multiple functions such as improving human immunity, enhancing memory and anti-aging.

[0003] Since Dendrobium officinale is a seasonal flower, it is very difficult to obtain fresh flowers outside the flowering season. China has a tradition of frying scented tea since ancient times. At present, the production methods of Dendrobium officinale scented tea include traditional frying, vacuum drying, microwave drying and freeze drying. Due to the high production costs of vacuum drying, microwave drying and freeze drying, they are still in the laboratory research stage. Therefore, the traditional frying method is still commonly used in actual production.

[0004] The current traditional processing method of Dendrobium officinale flower tea requires multiple steps such as withering, frying, baking, and drying. The low-temperature withering not only makes the processing time too long, but the temperature of the flower cannot quickly reach the temperature at which polyphenol oxidase is passivated, resulting in a large loss of nutrients in the Dendrobium officinale flower.

[0005] The existing production process will cause the tea to become dull in color after rolling, the flowers to be crisp, the petals to be easily damaged, the appearance after brewing to be poor, and the overall value to be low. In addition, the rolling method is relatively complicated, the yield is low, and it is not suitable for large-scale production. It also has great damage to the nutrients in the dendrobium flowers. At the same time, the efficacy of the dendrobium officinale flower tea itself is not maximized and retained, and it cannot meet people's usage needs well. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a preparation process for Dendrobium officinale flower tea with the function of lowering blood lipids, which solves the problems raised in the above background technology.
