The fructus Lycii Mel has effects of nourishing yin, invigorating kidney, nourishing liver, improving eyesight, nourishing liver and kidney, moistening lung, and relieving cough. The nectar has obvious nourishing effect, can relieve the body deficiency and can tonify qi and blood, and the date nectar contains rich vitamin c which can resist bacteria and diminish inflammation and improve the immunity of a human body.
In some embodiments of the present invention, the above-mentioned mixed honey solution after immersion is heated to 80-100 ℃, and the boiling temperature is 80-100 ℃. Decocting at the temperature can remove water in the ginseng slices and promote penetration of the ginseng slices into the mixed honey liquid.
In some embodiments of the present invention, the step of drying the decoction is specifically drying the decoction at 35-55 ℃ until the moisture content is 10-15%. The moisture of the dried product is dried to 10-15%, so that the dried product has certain moisture, good taste and difficult mildew and rot.
In some embodiments of the present invention, the vacuum level of the vacuum package is (-0.08) - (-0.1) MPa.
In some embodiments of the present invention, the low-temperature refrigeration is performed at 0-4 ℃. The cold storage at the temperature can ensure that the food can be stored for a longer time.

Examples of the experiments
The honey slices of fresh ginseng of examples 1-6 and comparative examples 1-3 were taken for organoleptic evaluation after 0 day, 1 month and 6 months of storage, respectively, 180 evaluators were invited, respectively, and equally divided into 9 groups, and the honey slices of fresh ginseng of examples 1-6 and comparative examples 1-3 were evaluated in terms of color, taste and flavor in turn. The color is golden yellow or honey, and is good for slight transparency; the taste is mellow, fresh and crisp, and is not soft; the taste is sweet but not greasy, and the aftertaste is good. The score of each item was divided into 10 parts, and the score of each item was calculated by taking the average of the score of each group, and the results are shown in Table 1.
TABLE 1

By analyzing and comparing table 1, it can be seen that the evaluation obtained in example 2 and examples 4 to 6 was the best in color; the evaluations obtained in example 2, example 4 and example 6 were the best in the texture; in terms of taste, the evaluation obtained in example 6 was the best; analysis and comparison show that the addition of various kinds of honey is most beneficial to the taste of the fresh ginseng honey slices, so that the fresh ginseng honey slices obtain the best taste, and the condition parameters of the example 2 are most suitable in terms of color and mouthfeel; comparing the three scores of comparative example 1, it can be seen that the evaluation on the mouthfeel is lowest, and it can be known that if scalding and cooling are not carried out, the mouthfeel is poor and the experience is poor; comparing the three scores of comparative example 2, it can be seen that the evaluation on mouthfeel is the worst, and it can be seen that if no impregnation is performed, the mouthfeel is poor; comparing the three scores of comparative example 3, it can be seen that it is very bad in taste, indicating that boiling is important for the taste of the fresh honey slices.
Comparing the evaluations of 0 day, 1 month and 6 months, it is apparent that the taste after storage of examples 1-6 is not much changed, indicating that the fresh honey pieces have little influence on the taste after storage, but comparing comparative examples 1-3, it is apparent that the color, taste and mouthfeel are greatly affected after storage for a period of time without scalding cooling, steeping and boiling treatment, indicating that the scalding cooling, steeping and boiling steps are important for the storage and storage of the fresh honey pieces.
In addition, the fresh ginseng honey slices used at this time are all randomly extracted and are not selected, and 180 evaluators do not eat bad fresh ginseng honey slices, which shows that the fresh ginseng honey slices prepared by the method are good in quality and not easy to be damaged.
In conclusion, the fresh ginseng slices are sliced and then are subjected to the hot water scalding and cooling process, so that enzymes contained in the ginseng slices are killed, the oxidative discoloration of the ginseng slices due to the enzyme action is avoided, the stable quality of the ginseng slices is further ensured, the cells of the ginseng slices can be damaged through the scalding and cooling process, the mixed honey liquid can be better absorbed in the subsequent dipping process, a good dipping effect is obtained, and in addition, the ginseng slices can be crisp in taste and have better eating experience; by soaking the ginseng slices, the concentration of the mixed honey liquid is higher than that of the cellular liquid of the ginseng slices, the water of the cellular liquid can be exchanged out, the water content of the ginseng slices is reduced, the concentration of the mixed honey liquid in the ginseng slices can be higher, and the soaked substances with good quality are obtained; the concentration of the mixed honey liquid in the ginseng slice can be further increased by heating and boiling the steeped substance, the content balance in the harvested fresh ginseng honey slice can be ensured after the treatment, the quality stability of the fresh ginseng honey slice is ensured, and the water content of the ginseng slice is further reduced after the treatment, so that the fresh ginseng honey slice is not easy to damage and the preservation time is longer; drying the decoction, further ensuring that the water content is reduced, sterilizing by ultraviolet radiation, and killing bacteria; the fresh ginseng honey slices can be stored at low temperature for a longer time, the storage period of the fresh ginseng honey slices is prolonged on the premise of not adding a chemical preservative, the storage cost of an enterprise is reduced, the fresh ginseng honey slices can obtain greater economic benefits, and the technical problem that the fresh ginseng honey slices are easy to break is solved.
The embodiments described above are some, but not all embodiments of the invention. The detailed description of the embodiments of the present invention is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
