[0002] Natural hot springs are widely believed to have many health benefits for the human body due to their rich mineral content and therapeutic effects, such as relieving fatigue, improving blood circulation, and nourishing the skin. With the development of artificial hot spring facilities, how to simulate the effects of natural hot springs by adding mineral supplements has become a focus of research and development. Using supplements to mimic the mineral content in natural hot springs can provide users with a similar bathing experience, so a variety of artificial hot spring mineral supplement products have been developed on the market.

[0055] In order to fully verify the rationality of the designed artificial hot spring mineral supplement formula, the experiment adjusted the proportion of each component, especially the content of medical stone powder, to examine the performance of the formula in multiple key performance indicators. The experiment focused on the role of medical stone in improving water quality and releasing minerals, combined with the influence of sulfide, polysulfide and other ingredients on the overall effect.

[0056] The experimental results are as follows:

[0057]

[0058] Setting and analysis of experimental variables:

[0059] Changes in medical stone powder content:

[0060] Example 1 and Example 2: The content of medical stone powder was set to 3% and 4% respectively, the purpose of which was to observe the effect of increasing the content of medical stone powder on the release of minerals and the improvement of water quality.

[0061] Example 4: The content of medical stone powder was increased to 5%, which is the highest value of medical stone powder in this experiment, to test its effect on water transparency, mineral release, uniformity, etc.

[0062] Comparative Example 1 and Comparative Example 2: The medical stone powder was set to 2% and 1% (minimum content) respectively to compare the impact of lower medical stone content on water quality and user experience.

[0063] Sulfide and polysulfide ratio adjustment:

[0064] The content of sulfide (sodium sulfide) and polysulfide (sodium polysulfide) was adjusted in the range of 1.5%-3%, with the purpose of observing their effects on mineral release and mineral balance in water quality under different ratios.

[0065] Adjust the ratio of spices and colors:

[0066] The proportion of spices and pigments can be adjusted in the range of 1%-2% and 2%-4% respectively. The change in the proportion of different spices (lavender essential oil, rosemary essential oil and lemon essential oil) and pigments (carotene, sodium copper chlorophyllin) will affect the final visual and olfactory experience.

[0067] Experimental procedures

[0068] 1. Prepare the mineral base:

[0069] In a stirring device, first place sodium chloride as the base and stir at low speed for 5 minutes.

[0070] According to the experimental group formula, medical stone powder, magnesium sulfate, potassium sulfate and magnesium chloride were added in sequence, and stirring was continued for 10 minutes to ensure uniform mixing.

[0071] 2. Preparation of liquid solution:

[0072] Place the hot spring water in a stirring device and add sodium metasilicate until it is completely dissolved.

[0073] Then, sodium sulfide and sodium polysulfide were added and stirred for 5 minutes to form a uniform liquid solution.

[0074] 3. Combination of liquid and solid:

[0075] Slowly pour the liquid solution into the mixed mineral base and continue stirring for 30 minutes, controlling the temperature at 20-30°C, until a uniform mixture is formed.

[0076] 4. Add flavors and colors:

[0077] Add the spices and colors in proportion to the mixture and continue stirring for 10 minutes until it is completely smooth.

[0078] 5. Drying and screening:

[0079] Use vacuum drying equipment, control the drying temperature at 40-50°C, maintain the vacuum degree at 0.08-0.1MPa, and dry for 6-8 hours.

[0080] After drying, the mixture is sieved to ensure uniform particles.

[0081]

[0082] Experimental data analysis:

[0083] Solubility:

[0084] The dissolution speeds of the first and second embodiments are relatively fast, especially the second embodiment, where the higher ratio of medical stone powder to other minerals can effectively improve the release and dissolution speed of the minerals.

[0085] The solubility of Comparative Example 2 is the worst. The low content of medical stone powder weakens the improvement effect on water quality, and the mineral particles are difficult to dissolve quickly.

[0086] Fragrance persistence:

[0087] The fragrance persistence of Example 2 and Example 4 is excellent, and the reasonable proportion of the spices enables the fragrance to last for a long time.

[0088] The aroma of the control group lasted for a shorter time, indicating that when the fragrance ratio was insufficient, the aroma dissipated quickly.

[0089] Visual effect and particle uniformity:

[0090] The color stability and particle uniformity of Example 2 and Example 4 are excellent, and the uniform pigment distribution and the fine particles of medical stone effectively improve the visual effect.

[0091] The visual effect of comparative example 2 is poor, the pigment distribution is uneven, and the particle size varies greatly.

[0092] Water transparency and the role of medical stone:

[0093] In Example 2 and Example 4, the content of medical stone powder is relatively high, the water transparency is significantly improved, and the minerals can be released more stably. In Example 4, in particular, the content of 5% medical stone powder significantly improves the clarity and mineral balance of water.

[0094] In the control group, the content of medical stone powder was low, the water quality was not clear enough, the release effect of minerals was poor, and the transparency was low.

[0095] User experience rating:

[0096] The user experience scores of Examples 2 and 4 were the highest, and the comprehensive performances of solubility, aroma persistence, visual effect, and water quality improvement were all excellent, and the high content of medical stone powder was the key factor.

[0097] The control group scored lower, especially when the medical stone powder content was lower, and the user experience was obviously worse than that of the experimental group.

[0098] The experimental results clearly show that medical stone powder has a significant effect on improving hot spring water, especially at a high content (4%-5%), which can effectively improve water transparency and the uniformity of mineral release. Medical stone can not only improve solubility, but also absorb impurities in water, improve water quality, and simulate an effect closer to that of a natural hot spring.

[0099] Embodiment 4 Since the content of medical stone powder is the highest, it shows the best water clarity, uniform release of minerals, solubility and user experience. Through experimental verification, the reasonable proportion of medical stone powder in the formula is the key factor for improving water quality and has significant practical application value.
