Embodiment 1
[0037] The optimization of embodiment 1 ginseng extraction conditions
[0038] The preparation method of ginseng extract: add 8 to 10 times the volume of water (that is, the ratio of solid to liquid is 1g: (8 to 10) mL, and the other similar descriptions are the same) to artificially planted ginseng or ginseng adventitious roots that are less than 5 years old. The ginseng extract is obtained by extracting 1 to 2 times in a slightly boiling state, and the single extraction time is 40-60 minutes.
[0039] Orthogonal design experiment was adopted to optimize the conditions of water addition, extraction times, and extraction time under the slightly boiling state (see Table 1). The investigation indicators were extraction rate and ginsenoside content. The results are shown in Table 2. The detection method of ginsenoside refers to "Chinese Pharmacopoeia", and the external standard method is used for determination. The specific processing is as follows, and the identification map is ...
Embodiment 2
[0061] The optimization of embodiment 2 Rosa roxburghii extraction conditions
[0062] The preparation method of Rosa roxburghii extract: select mature Rosa roxburghii dried fruit, add 10 to 20 times the volume of water after crushing, extract 1 or 2 times at 40 to 60 ° C, and the single extraction time is 10 to 60 minutes to obtain Rosa roxburghii extract liquid.
[0063] Orthogonal design experiments were adopted to optimize the conditions of water addition, extraction times, extraction time, and extraction temperature (see Table 3). The investigation indicators were extraction rate and vitamin C content. The results are shown in Table 4.

[0068] Taking the content of VC as the main determinant factor, followed by the extraction rate as a reference, the optimal extraction conditions of Rosa roxburghii extract were determined as follows: the ratio of solid to liq...
Embodiment 3
[0078] The optimization of embodiment 3 coffee extraction conditions
[0079] The preparation method of the coffee extract: select roasted coffee beans to make coffee powder, the ratio of material to liquid is 1g:(10-20)mL, and extract with slightly boiling drinking water for 2-4min to obtain the coffee extract.
[0080] Orthogonal design experiment was adopted to optimize the conditions of solid-liquid ratio and extraction time (see Table 7). The investigation index was soluble solids content, and the results were shown in Table 8. The soluble solids content can reflect the "strength" of coffee aroma and taste. The International Specialty Coffee Association, through coffee cupping and acceptance analysis, believes that when the soluble solids content is 0.70-1.38%, the balance of coffee flavor is the best, and it is often used as one of the quality standards for evaluating coffee liquid.
