Description

Technical Field

[0001] The present invention relates to the technical field of ginseng processing, and particularly relates to a non-heating instant ginseng and a preparation method thereof. Background Art

[0002] The Chinese medicinal material ginseng is a qi-tonifying medicine, which is the dried root and rhizome of the plant Panax ginseng C. A. Mey. of the Araliaceae family. Ginseng is rich in pharmacological components and has high medicinal value. Its fleshy root is a powerful tonic, suitable for treating symptoms such as regulating blood pressure, restoring heart function, neurasthenia, and physical weakness, and also has effects such as expectorant, stomachic, diuretic, and excitatory effects. For a long time, ginseng has been widely used as a tonic medicinal material in various functional foods or therapeutic health products. However, taking ginseng in excess or for a long time will cause a series of "heating" symptoms such as nosebleeds, oral ulcers, and sleep disorders. Ginseng is usually decocted and taken, or can also be chewed, stewed, soaked in wine or used in soup. Due to the presence of ginsenosides in ginseng, it has an obvious bitter taste and a sense of residue when chewed.

[0003] At present, the processing of ginseng is limited to slicing ginseng and then drying it to obtain ginseng slices, which can only be taken by soaking in water subsequently. It not only fails to achieve instant consumption but may also cause the taker to get heated. Preparing fresh-cut ginseng slices into honey slices cannot achieve the optimal taste and efficacy of ginseng. Therefore, there is an urgent need to invent a processing method for non-heating instant ginseng, so that the prepared ginseng not only has a good taste but also has a good qi-tonifying effect. Summary of the Invention

[0064] Experimental Example 1

[0065] Animal experiment

[0066] Select male SD rats aged 6 - 7 weeks and weighing 200 - 220 g, and randomly divide them into 7 groups with 20 rats in each group. They are the blank group, Example 1 group, Comparative Example 1 group, Comparative Example 2 group, Comparative Example 3 group, Comparative Example 4 group, and Comparative Example 5 group; the dosage of ginseng for each group of SD rats is 0.5 g / kg (except for the blank group, each group is administered at 4 times the maximum daily dose for adults specified in the 2020 edition of the Chinese Pharmacopoeia); the blank group takes an equal mass of physiological saline.

[0067] Each group of SD rats drinks water and eats freely, is raised in the same environment, and is continuously administered according to the above grouping for 4 weeks. Every 7 days (on the 0th, 7th, 14th, 21st, and 28th days), observe the mental state, hair color, water intake and food intake of the rats, and monitor the water content of the feces, anal temperature, and saliva volume of the rats. Remove the data with large differences, and take the average value of the other data. The specific results are shown in Table 1 - Table 3.

[0068] Among them, the water content of feces was measured by the dry weight method: the weights of the feces of rats before and after drying were measured respectively, and the water content of feces (%) = (weight before drying - weight after drying) / weight before drying * 100%.

[0069] The method for measuring anal temperature was as follows: 1 hour after administration, the anal temperature was measured with a thermometer.

[0070] The saliva volume was collected by the cotton ball wiping method: 1 hour after administration, the cotton ball was put into the rat's mouth and wiped once in each of the up, down, left, and right directions, and then placed for 3 minutes. The masses of the cotton ball before and after were measured to obtain the saliva volume of the rat.

[0078] Through observation, the hair of the rats in the blank group, Example 1 and Comparative Example 3 was shiny, the temperament was gentle, and the diet was normal during the 0 - 28 days of the experiment; in the Comparative Example 1 group, it was obvious that after the 14th day, the hair color was dull, the mental state was poor, the feces were dry, showing mild symptoms of excessive internal heat, and after the 21st day, there was hair loss, irritability, and dry feces, showing obvious symptoms of excessive internal heat; in Comparative Example 2, Comparative Example 4 and Comparative Example 5, mild symptoms of excessive internal heat appeared on the 21st day, and the symptoms of excessive internal heat aggravated on the 28th day, but the symptoms of excessive internal heat were lighter than those in Comparative Example 1.

[0079] It can be clearly seen from the data in Table 1 - Table 3 that the use of lily, mint, ophiopogon root, poria cocos and licorice in the present invention can significantly reduce the symptoms of excessive internal heat caused by ginseng.

[0080] Experimental Example 2

[0081] Sensory experiment

[0082] (1) A sensory evaluation panel composed of 10 professionally trained personnel evaluated and summarized the appearance, taste and color of the ginseng in Examples 1 - 3 and Comparative Examples 1 - 5.

[0083] The sensory evaluation of the instant ginseng that does not cause internal heat in Examples 1-3 is basically consistent: the whole ginseng has a light yellow appearance, fewer wrinkles, is ornamental, has a crisp taste, has a comfortable, fresh and slightly sweet taste in the mouth, and has no residue.

[0084] Comparative Example 1: The whole ginseng has a light yellow appearance, fewer wrinkles, is ornamental, has a crisp taste and no residue, but has a distinct earthy smell and a bitter taste.

[0085] Comparative Example 2: The whole ginseng has a yellow appearance, fewer wrinkles, is ornamental, has a crisp texture, and has a comfortable and refreshing taste, but is slightly bitter.

[0086] Comparative Example 3: The whole ginseng has a yellow appearance and many wrinkles, which makes it less ornamental. It has a comfortable and refreshing taste, but also has a residue-like feel.

[0087] Comparative Example 4: The ginseng slices are white and yellow in the middle, and the skin is light yellow. They are not ornamental, taste slightly bitter, and have a residue feeling. They cannot be eaten immediately.

[0088] Comparative Example 5: The ginseng honey slices are reddish brown in color, not ornamental, have the sweetness of honey and feel like residue when put into the mouth.

[0089] (2) A satisfaction survey was conducted on 100 consumers on the ginseng of Examples 1-3 and Comparative Examples 1-5, respectively, and the results were divided into five levels: very satisfied, satisfied, average, dissatisfied, and very dissatisfied. The specific results are shown in Table 4.

[0090] Table 4 Ginseng Satisfaction Survey Table for Examples 1-3 and Comparative Examples 1-5 (%)

[0091] Group Very satisfied Satisfied Average Dissatisfied Very dissatisfied Example 1 67 30 3 0 0 Example 2 60 25 14 1 0 Example 3 65 27 8 0 0 Comparative example 1 30 30 25 10 5 Comparative example 2 45 20 25 10 0 Comparative example 3 21 29 26 15 9 Comparative example 4 20 18 35 22 5 Comparative example 5 30 27 30 12 1

[0092] It is obvious from the sense organs and satisfaction of professionally trained personnel and consumers that the instant ginseng without getting angry obtained by the preparation method of the present invention can significantly reduce the residue feeling and bitterness of ginseng, and the whole ginseng is more ornamental and easily accepted by consumers.

[0093] Experimental Example 3

[0094] 150 women aged 30-40 years who had given birth and had symptoms of qi and blood deficiency (dizziness, fatigue, physical weakness, fatigue, low blood pressure, and a disease course of 1 to 3 years) were selected and divided into three groups on average. There was no significant difference in age, disease course, etc. among the three groups before treatment, so subsequent clinical trials can be carried out.

[0095] Grouping: One group chewed the instant ginseng of Example 1 of the present invention, 3 - 9 g per day; one group chewed the instant ginseng of Comparative Example 1, 3 - 9 g per day; the last group took the Changbai Mountain ginseng honey slices of Comparative Example 5, 1 - 2 slices per day. After 60 days of taking by the three groups, the medicinal effects and the results of getting angry were counted, as shown in Table 5.

[0096] Judgment criteria for diagnosis:

[0097] Marked effect: Symptoms such as dizziness, fatigue, and proneness to fatigue disappear, physical fitness is restored, and blood pressure is within the normal range;

[0098] Effective: Symptoms such as dizziness, fatigue, and proneness to fatigue have improved compared with before treatment;

[0099] Ineffective: The symptoms are the same as before treatment and there is no improvement.

[0100] Symptoms of getting angry: Appearing one or more of the symptoms such as chapped lips, bitter mouth and dryness, fever all over the body, and dry and hard stools, and judged in combination with the pulse condition.

[0101] Table 5 Effects of different ginsengs on qi and blood deficiency

[0103] As can be seen from Table 5, the total effective rate of the instant ginseng of the present invention is 98%, which is significantly higher than that of Comparative Example 5, indicating that the instant ginseng of the present invention has a significant effect of tonifying qi and blood. Moreover, after taking the instant ginseng of the present invention, no symptoms of getting angry appeared. It shows that the instant ginseng of the present invention can not only improve the taste but also ensure the medicinal effect and achieve the effect of not getting angry.

[0104] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
