Examples
Embodiment 1
[0016] In 1mL honeysuckle extract solution, add ethanol until the alcohol degree is 60-70%, then cool down, recover ethanol after filtration, then add other adjustment components, and then adjust the pH value to 5 with sodium hydroxide.
[0017] Observation table 1,
[0018] Table 1
[0019]
[0020] As can be seen from Table 1, when the direct pH of the honeysuckle extraction solution is adjusted to 4-6, the pH of the solution gradually decreases as the storage time prolongs, from 5.09 to 4.03, and the content of chlorogenic acid in the solution increases from 525 to 4.03. Reduced to 176, the appearance of the solution gradually changed from brownish-yellow and clear to brown, and a large number of massive precipitates were formed at the bottom of the solution.
Embodiment 2
[0022] Add 10 mg of pea maltodextrin and 10 mg of β-cyclodextrin to 1 mL of honeysuckle extract solution, mix until uniform, add ethanol until the alcohol degree is 60-70%, then cool down, recover ethanol after filtration, and then add other adjustment components, Then adjust the pH value to 5 with sodium hydroxide.
[0023] Observation table 2,
[0024] Table 2
[0025]
Embodiment 3
[0027] Add 15 mg of pea maltodextrin, 5 mg of β-cyclodextrin, and 5 mg of hydroxypropyl-β-cyclodextrin to 1 mL of honeysuckle extract solution, mix until uniform, add ethanol until the alcohol degree is 70-75%, and then cool down. After filtering with a 0.2 μm microporous membrane, the ethanol is recovered, and then other adjustment components are added, and then the pH is adjusted to 4-4.5 with sodium hydroxide.
