Problems solved by technology

The contents of DMY and RS in the drink are significantly lower than the content requirements of the composition of the present invention, and it has not been explained that RS has any influence and law on the solubility, stability and mouthfeel of DMY. For the high-content DMY described in the present invention - The proposal of the RS composition does not serve as a technical guide

Embodiment 1

[0063] Effect of RS on improving the solubility and stability of DMY

[0064] Method: Take an appropriate amount of DMY (content ≥ 98%), RS (food grade, dietary fiber content ≥ 90%), mix with an appropriate amount of pure water, heat to 80°C for 10 minutes under stirring to dissolve, then pack and seal in screw-top test tubes (10ml / bottle), sterilized in a water bath at 90°C for 10 minutes, and prepared as DMY 10mg / ml-RS series aqueous solution. Then put the test samples at room temperature (20-30°C) and in the refrigerator (4°C) for observation for at least 30 days. The solubility and property stability of the DMY-RS aqueous solution were evaluated by taking the volume percentage of the solution precipitation volume in the total volume as an index; the taste (bitterness) of the solution was evaluated by personnel tasting.

[0065] The results show: (see attached figure 1 )

[0066] 1. The effect of RS on the solubility and stability of DMY presents a complex curve relation...

Embodiment 2

[0072] RS improves the solid-liquid conversion (redissolution) performance of DMY

[0073] Method: Refer to Example 1 to prepare DMY 10mg / ml-RS series aqueous solution, then heat (80-90°C) to concentrate and dry to a dry product, add an appropriate amount of water to the original liquid volume, stir and mix at room temperature, and leave it at room temperature for 1 Day, observe the reconstitution effect, and evaluate the dissolution effect and stability after reconstitution with the properties of the reconstitution solution and the relative volume precipitation (%) as the index.

[0074] The results show: (see attached figure 2 )

[0075] 1. When RS / DMY=5, add 5-10 times water to the dry product of DMY-RS solution at room temperature and mix well, the reconstituted solution turns into a cloudy liquid after standing still, and the amount of precipitation is obviously greater than that of the reference product (DMY 10mg / ml), prompting At this time, RS has the function of inh...

Abstract

The invention provides a flavone high-fiber composition and a preparation method thereof. Research discovers that the content of resistant dextrin (RS) is not lower than 12 times of the content of dihydromyricetin (DMY), that is to say, the RS / DMY ratio is more than or equal to 12, the dissolvability, the stability and the redissolving effect of dihydromyricetin are significantly improved, the bitter taste (the debitterizing effect) of dihydromyricetin is significantly reduced, and the effect is stronger along with the increase of the relative content of resistant dextrin. According to the discovery, the dihydromyricetin and resistant dextrin composition with high content and the preparation method thereof are researched and developed, and the composition has important industrial application value.

Description

[0001] field of invention [0002] The invention relates to the technical field of research and development of plant functional health care preparations and beverages. More specifically, the present invention relates to a composition with high content of dihydromyricetin and resistant dextrin and a preparation method thereof. Background technique [0003] Dihydromyricetin (DMY), also known as ampelopsin, is a white needle-like crystal, slightly soluble in water, and easily soluble in hot water, ethanol and acetone. DMY is a natural dihydroflavonol compound, mainly derived from vine tea, also known as Maoyanberry tea, nectar tea, etc. (Ampelopsis megalophylla Diels et.Gilg) and other plants of the genus Snake Grape, the DMY content in the young leaves and tea tips of vine tea can usually reach 20-30%, which is the known plant source with the highest DMY content. Vine tea contains no or very little (negligible) caffeine. Hovenia dulcis, bayberry bark, etc. are also rich in DM...
