Abstract

The preparation method of Fritillaria flower tea disclosed in the present invention comprises the following steps: removing impurities from freshly picked Fritillaria flowers, removing unopened flower buds and over-opened flower buds, taking flower buds that are about to open on Fritillaria flower spikes, selecting and grading, and drying in a fluidized bed in a nitrogen or air atmosphere at 30-60° C. to obtain Fritillaria flower tea products. The dried Fritillaria flower tea products can be used as products in their original form, or they can be ground into powder, pressed into tablets, or packed into capsules using a capsule filling machine. The Fritillaria flower tea products of the present invention adopt a low-temperature fluidized bed drying production process, which is not only suitable for large-scale production requirements, but also avoids the destruction of biologically active components in Fritillaria flowers. At the same time, due to the use of a low-temperature fluidized bed process, compared with freeze-dried Fritillaria flowers, the processed Fritillaria flowers have no grassy taste, a more comfortable taste, better color, and are more conducive to home drinking.

Description

The preparation method of fritillary flower tea

technical field

The invention relates to a preparation method of Fritillaria scented tea, which belongs to the field of health-care tea production.

Background technique

Flowers are the sexual reproductive organs of seed plants, and are new organs produced by plants after sufficient vegetative growth. General flowers not only have biological pedicel, receptacle, calyx, corolla, stamen group and pistil group, but also accumulate rich nutritional active ingredients to meet the fertilization and development of seeds. These rich bioactive ingredients also have good nutritional and medicinal value. Therefore, people have always attached great importance to the development and utilization of flowers, and processed flowers into various medicinal and edible products that meet people's various needs. .

Fritillary is a commonly used traditional Chinese medicine for reducing phlegm, relieving cough, clearing heat and nourishing the lungs. It has a very long history of medicinal use. The main source of its medicinal materials is the genus Fritillaria in the family Liliaceae. There are about 130 species of this genus in the world. Fritillaria thunbergii Miq., a typical plant of the genus Fritillaria, is one of the famous Chinese medicinal materials "Zhe Bawei", a treasure in the Fritillaria family, and is an essential medicine in Chinese medicine prescriptions for reducing phlegm, relieving cough, clearing heat and nourishing the lungs. It is a perennial herb with hemispherical bulbs. Also known as Zhebei, Dabei, Xiangbei, Yuanbao, Zhubei, the bulb is used as medicine, which has the effects of clearing away heat and moistening the lungs, reducing phlegm, relieving cough and dispelling stagnation, etc. It is mainly used for upper respiratory tract infection, sore throat, bronchitis, lung abscess, lung Hot cough, phlegm, stomach, duodenal ulcer, mastitis, goiter, pain, furuncle and swollen poison. The medicinal material Fritillaria has a long history of medication. "Materia Medica Justice" contains: Like Fritillaria, the bitter cold is relieved, but it can dissipate stagnation. "Compendium Supplements" contains: detoxification and phlegm, open lung qi, and those who have phlegm due to wind and fire in the lungs are suitable for this. It grows wild in forests or hillside grasses, distributed in Zhejiang, Jiangsu, Hunan and other provinces. There are a large number of cultivations in Ningbo, Pan'an and other regions in Zhejiang, and demonstration cultivations in other regions. In recent years, after the efficacy of Fritillaria fritillaria in inhibiting lung cancer and liver cancer has been affirmed, the value of Fritillaria fritillaria has increased by a hundred times, the price has risen day by day, and the production and sales volume have increased sharply.

Modern studies have shown that the main biologically active substances of Fritillaria are alkaloids and their glycosides. These active ingredients are not only found in the bulbs of Fritillaria, but also in the stems and flowers, especially the alkaloids in flower buds. The content is the highest, reaching 0.6%. However, the bulbs of Fritillaria are used in traditional medicine, and other vegetative organs are rarely used. The 1977 edition of the Chinese Pharmacopoeia once announced that fritillary flower also has the effect of relieving cough and reducing phlegm, and can be used for the treatment of cough with excessive phlegm and bronchitis. Clinical application shows that it has few reports of adverse reactions, its toxicity is very low, and it can be used as a kind of food with both medicine and food. The reported Fritillaria products mainly include Fritillaria flakes and Fritillaria infusion, both of which are used for relieving cough, reducing phlegm, and for coughing with excessive phlegm and bronchitis. But for the development of other products of Fritillaria, especially its development as tea beverage is still in a blank.

Contents of the invention

The object of the present invention is to provide a kind of preparation method of fritillary flower tea.

The preparation method of Fritillaria scented tea of the present invention, its steps are as follows: Freshly picked Fritillaria flowers, go through impurity removal, remove unopened flower buds and overblown flower buds, take the flower buds that will open on Fritillaria flower spikes, select After classification, dry in a fluidized bed in a nitrogen or air atmosphere at 30-60°C to obtain Fritillaria flower tea products.

The dried Fritillaria scented tea product of the present invention can be used as a product in the original form, or it can be ground into powder, pressed into tablets, or packed into capsules with a capsule filling machine.

The fritillaria that the present invention adopts is preferably the flower that fritillary fritillaria blooms.

The beneficial effects of the present invention are:

The Fritillaria scented tea product of the present invention adopts a low-temperature fluidized bed drying process, which not only can meet the requirements of large-scale production, but also avoids the destruction of biologically active components in the Fritillaria flower.

Detailed ways

The technical solutions of the present invention will be further described below through specific examples.

Example 1

The freshly picked fritillary flowers are removed from impurities, unopened buds and overblown buds are removed, and the flower buds that are about to open on 10 kg fritillary flower spikes are taken, selected and graded, and nitrogen at 50 ° C is used as the drying gas. Dried in a fluidized bed until the water content is below 8.5%, screened and sorted, and put into storage. According to the national standard GB/T5009.124-2003 for amino acid analysis, the results are shown in Table 1, which shows that the processed fritillary tea is rich in amino acids, including essential amino acids for the human body. Liquid chromatography-mass spectrometry analysis (seeing Fig. 1) shows that it contains the same peiminin A and peiminin B of the fritillaria bulb, and also contains the stronger water-soluble peiminin A glucoside, which Not only is it more conducive to the absorption of the human body, but it can also be hydrolyzed into peimin A under the action of gastric acid in the human body.

Example 2
