Please refer to tables 1 and 3, and the contents of the above comparative examples and examples, comparing comparative example 1 with example 1, comparative example 1 adopts a mode of using pine needles, spirulina and loquat leaves together to protect liver and stomach, eliminates the phenomenon of stomach discomfort of a small part of a product drunk by people, treats spirulina by adopting a mode of cleaning, high-temperature sterilization and drying, and removes fishy smell of spirulina by using a mode of making tea with pears, pine needles and loquat leaves, but the fishy smell removing effect is still not ideal because of the spirulina platensis, example 1 prepares spirulina into a fluid state on the basis of comparative example 1, boils together with honey and pears, dries to prepare dried pears with honey and spirulina, adopts a mode of using a compound spirulina layer outside the pears, and improves the fishy smell removing effect compared with comparative example 1, but still a small part of the product drunk by people has dry eye phenomenon;

comparing example 1 with example 2, it can be seen that in example 2, on the basis of example 1, wild chrysanthemum flower is added to calm the liver and improve the eyesight, the dry eye phenomenon of a small part of people drinking the product is eliminated, the fishy smell of spirulina is further neutralized, and the cold-dispelling property of liquorice is increased, so that the product has better universality, and the effects of diminishing inflammation and promoting urination, reducing blood fat and blood pressure are better when being used with a loose needle;

comparing example 2 with example 3, it can be seen that in example 3, based on example 2, the method of soaking in saline-stirring slowly for a short time is used to remove the fluff on the surface of the loquat leaves, so that the preparation method is more suitable for the line production of tea substitute processing, and the manpower resources are saved;

comparing example 3 with example 4, it is known that example 4 adds the spirulina deodorization treatment in the vacuum environment on the basis of example 3 to further reduce the fishy smell of spirulina;

comparing example 4 with example 5, it can be seen that in example 5, based on example 4, orange peel components are added to neutralize, and the orange peel components can be used for treating stomach disorder, nausea and vomiting, and if stomach cold and vomiting, under the combined action of liquorice, stomach cold can be reduced, pine needles, loquat leaves and wild chrysanthemum cold can be eliminated, the phenomena of excessive phlegm and cough can be adjusted by using the orange peel components together with loquat leaves, pears and wild chrysanthemum, and the orange peel is processed in a freeze-drying mode, and through GC-MS analysis, the content of orange peel essential oil is about 2.83%, the content of flavone is about 18.09%, main nutritional components in the orange peel are retained to the greatest extent, so that the effect of the orange peel components in water soaking is better;

referring to Table 2 and the contents of examples 2 to 5, it can be seen from comparative examples 2 to 4 that the concentration of the citric acid solution was 1.5% and the oil adsorption rate was about 95.6% at a heating temperature of 45 ℃ when treating wild chrysanthemum in example 2;

in the case of treating wild chrysanthemum in example 3, the concentration of the citric acid solution is 0.1mol/L, and the oil adsorption rate is about 89.3% at a heating temperature of 45 ℃, because the concentration of the citric acid solution is too low and the pH value of the solution is too high, cations generated by chitosan and an acidic solution are weakened, the oil wrapping effect is weakened, and the oil adsorption rate is reduced;

in example 4, when treating wild chrysanthemum, the concentration of the citric acid solution is 1.5%, the oil adsorption rate is about 84.1% at a heating temperature of 40 ℃, chitosan adsorption is a dynamic process, and the thermal motion of the whole system is accelerated by increasing the temperature, and vice versa, so that the oil adsorption rate is reduced due to the temperature reduction when the temperature is reduced;

when the chrysanthemum indicum is treated in the embodiment 5, the concentration of the citric acid solution is 1.5%, the oil adsorption rate is about 88.9 when the heating temperature is 50 ℃, the concentration of the citric acid solution is increased due to the temperature rise, and the oil adsorption rate is increased due to the cation enhancement;

as can be seen from the above, example 5 produced the most synergistic beverages, with minimal discomfort and the best taste compared to comparative example 1, examples 1-4, and therefore example 5 is considered the most preferred embodiment of the present invention;

example 2 the deoiling effect was the best compared to the treatment of wild chrysanthemum flowers of examples 3-5, therefore, example 2 is considered as the best example for treating wild chrysanthemum flowers according to the invention.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-described embodiments. All technical schemes belonging to the idea of the invention belong to the protection scope of the invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention, and such modifications and embellishments should also be considered as within the scope of the invention.
