Method used

Amino acid is important nutrition and flavor substance, and as shown in table 2, 22 kinds of free amino acids are detected altogether in sample, and glutamic acid (415mg/100mL) content is the highest, and aspartic acid (233 mg/100mL) takes second place , which is an umami amino acid, which further proves the refreshing and mellow taste of tea soup. In addition, except for lysine and tryp...

Abstract

The invention belongs to the technical field of health care product processing, and in particular relates to small fiveleaf gynostemma herb powder, a preparation method thereof, and a preparation method of a small fiveleaf gynostemma herb powder drink. The preparation method of the small fiveleaf gynostemma herb powder includes the steps of picking raw materials, performing cleaning, performing dehydrating, performing spreading airing, performing steam enzyme deactivation, performing hot air dehydration and drying, and performing ultra-fine crushing; and the preparation method of the drink comprises the step of brewing the powder for drinking. The preparation method of the small fiveleaf gynostemma herb powder provided by the invention has a simple and reliable process, and can be used forlarge-scale production; the preparation process of the ultra-fine powder tea drink has lower costs, and do not use any additives, so that the drink is safe and non-toxic; and compared with commercially available fiveleaf gynostemma herb tea, the drink provided by the invention has a brighter color, high transparency and a better taste, contains a lot of biological active components such as saponins, flavonoids, polyphenols, polysaccharides and amino acids, and has extremely high nutritional and health care value.

Example Embodiment

[0035] Example 1:
[0036] This embodiment provides a method for preparing small blue powder, which is prepared in the following manner:
[0037] First pick the Gynostemma pentaphyllum and wash it to remove the debris. Then, the cleaned Gynostemma pentaphyllum is dehydrated, and then the dehydrated Gynostemma pentaphylla is spread and dried. After drying, the Gynostemma pentaphyllum is steam-cured, and then hot-air dehydration is performed to remove the dehydrated Gynostemma. Gynostemma pentaphyllum is dried by hot air, and finally, the dried Gynostemma pentaphyllum is embrittled, and the embrittled Gynostemma pentaphyllum is superfinely pulverized to obtain small blue powder.

Example Embodiment

[0038] Example 2:
[0039] On the basis of Example 1, it is preferable to pick the Gynostemma pentaphyllum first and then wash it with water twice, the first washing is 3-6min, the second washing 5-10min, and then the dehydrated Gynostemma is placed in natural air to wither 2-4h, and then steam curing. During this process, the steam temperature is 180-240℃, and the curing time is 40-60s. After the steam curing is completed, hot water dehydration is performed. The dehydration temperature is 100-120℃ and the dehydration time is 10- 20min, the dried Gynostemma pentaphyllum is dried with hot air, the drying temperature is 70-90℃, and the drying time is 20-60min. The dried Gynostemma pentaphyllum is embrittled, and then the embrittled Gynostemma pentaphyllum is broken Into the 800-1200 mesh sieve to obtain small blue powder, and use the laser particle size analyzer to measure its particle size such as figure 1 Shown.
[0040] The small blue powder prepared by the method of Example 1 or 2 has a particle size of about 1 μm, and the preparation process is simple and feasible, and the results are accurate and reliable. The active ingredients in Gynostemma pentaphyllum can be retained to the greatest extent, the quality is stable, and it can be stored for a long time at room temperature. The color and quality are basically the same as fresh products.
[0041] The yield of saponins extracted from this small blue powder using response surface method was 5.02±0.6%, while the yield of saponins from common Gynostemma was only 3.48±0.32%.
[0042] Table 1 below is a comparison table of the yield of saponin in the small blue powder extracted by the three response surface method and the common Gynostemma pentaphyllum.

Example Embodiment

[0045] Example 3:
[0046] This embodiment provides a method for preparing a small blue powder drink, that is, the small blue powder prepared in Example 1 or 2 is added to water at a temperature below 50°C to brew, and the water volume is 400-500 times that of the small blue powder, 2 minutes Shake afterwards and drink.
[0047] The preparation method of the small blue powder drink provided in this embodiment does not require high equipment requirements, and the production conditions are easy to realize, which is convenient for large-scale industrial production, and the prepared drink does not require any additives, the soup is bright green, and the taste is mellow and has a rich flavor. The aroma of tea improves the color, aroma and taste of tea soup, and effectively preserves the bioactive components and nutrients in Gynostemma pentaphyllum (refer to Table 1).
