Description

Technical Field

[0001] This invention relates to a fruit and vegetable washing liquid formulated from pure natural plant extracts or essential oils. Background Technology

[0002] Everyday chemical fruit and vegetable detergents are gradually becoming indispensable necessities in modern society. People are unknowingly becoming dependent on them. However, while using these detergents, chemical pollution harms human health through various channels. As people widely use these detergents to wash fruits and vegetables, chemical toxins seep into the body through countless pores, and chemical pollution enters through the mouth and skin, accumulating over time. Because the harm from this pollution is not immediately apparent, it is often overlooked. Therefore, improving fruit and vegetable detergents and using those that are harmless to humans, do not damage the living environment, and are non-toxic and pollution-free has become an urgent priority. Summary of the Invention

[0003] The purpose of this invention is to provide a fruit and vegetable washing liquid that has sterilization, disinfection, and safe stain removal properties.

[0004] According to a first aspect of the present invention, a fruit and vegetable washing liquid is provided, comprising: 1.0%-1.5% Atractylodes lancea volatile oil, 0.8%-1.2% Cinnamomum cassia volatile oil, 0.1%-0.2% sodium citrate, 0.05%-0.06% baking soda, 2%-3% cocamidopropyl betaine, 6%-7% sodium lauryl ether sulfate, 10%-12% sodium dodecyl sulfate (TEA), 2%-3% cocamidopropyl betaine, 3%-4% glycerin, and 1%-1.5% fragrance.

[0005] According to a preferred embodiment of the present invention, the fruit and vegetable washing liquid may include: 1.0%-1.2% Atractylodes lancea volatile oil, 0.8%-1.0% Cinnamomum cassia volatile oil, 0.1%-0.2% sodium citrate, 0.05%-0.06% baking soda, 2%-3% cocamidopropyl betaine, 6%-7% sodium lauryl ether sulfate, 10%-12% sodium dodecyl sulfate (TEA), 2%-3% cocamidopropyl betaine, 3%-4% glycerin, and 1%-1.5% fragrance.

[0006] According to a further preferred embodiment of the present invention, the fruit and vegetable washing liquid may include: 1.0%-1.5% Atractylodes lancea volatile oil, 0.8%-1.2% Cinnamomum cassia volatile oil, 0.1%-0.3% Clematis chinensis oil, 0.1%-0.2% sodium citrate, 0.05%-0.06% baking soda, 2%-3% cocamide DEA, 6%-7% sodium lauryl ether sulfate, 10%-12% TEA sodium dodecyl sulfate, 2%-3% cocamidopropyl betaine, 3%-4% glycerin, and 1%-1.5% fragrance. Adding a small amount of Clematis chinensis (medicinal herb) oil can further shorten the sterilization time and improve the bactericidal effect, which may be related to the synergistic effect brought about by its penetration properties, as well as its auxiliary bactericidal properties.

[0007] According to a specific embodiment of the present invention, the remaining component in the above-mentioned fruit and vegetable washing liquid is preferably purified water.

[0008] According to a second aspect of the present invention, a method for producing the above-mentioned fruit and vegetable washing liquid is provided, comprising:

[0009] Mix the purified water, sodium citrate, and baking soda thoroughly.

[0010] Then add cocamidoyl DEA, sodium lauryl ether sulfate, sodium dodecyl sulfate (TEA), cocamidopropyl betaine, glycerin, and flavoring, respectively.

[0011] Stir to dissolve completely; and

[0012] Finally, add Atractylodes lancea oil, Cinnamomum cassia oil, and optionally Clematis chinensis oil, and stir well.

[0013] According to the production method of the present invention, Atractylodes lancea oil and / or Cinnamomum cassia oil and / or Clematis chinensis oil are preferably prepared continuously by the following process:

[0014] Add Atractylodes rhizome powder and / or Cinnamon twig powder and / or Clematis chinensis powder to an extractor equipped with a screw conveyor.

[0015] The first storage tank containing pure water is heated to generate water vapor;

[0016] Water vapor is condensed into liquid water by a cooler and then passed into an extractor to immerse the powder of Atractylodes lancea rhizome and / or Cinnamomum cassia twig and / or Clematis chinensis root.

[0017] When the liquid level in the extractor is higher than the highest point of the siphon pipe connecting the extractor and the first storage tank, the extractant in the extractor automatically enters the first storage tank through the siphon pipe.

[0018] When the extract in the extractor becomes colorless, start the screw conveyor in the extractor to discharge the wet powder of Atractylodes lancea rhizome and / or wet powder of Cinnamomum cassia twig and / or wet powder of Clematis chinensis from the extractor, and at the same time add (fresh) Atractylodes lancea rhizome powder and / or Cinnamomum cassia twig powder and / or Clematis chinensis powder into the extractor.

[0019] Stop heating the first storage tank and simultaneously start the second storage tank to continue the above steps; and

[0020] The extract in the first storage tank is separated to obtain Atractylodes lancea oil and / or Cinnamomum cassia oil and / or Clematis chinensis oil.

[0021] According to a preferred embodiment of the present invention, the powdered rhizome of Atractylodes lancea, the powdered cinnamon twig, and optionally the powdered Clematis chinensis are mixed in a certain proportion before the plant oil extraction process is performed. In this case, since the various active plant components undergo a high-temperature reaction and binding process during extraction, a stronger synergistic bactericidal effect can be formed.

[0022] The Atractylodes lancea (volatile) oil of this invention can be extracted from the dried rhizomes of Atractylodes lancea or Atractylodes dasycarpus, plants belonging to the Asteraceae family. The Atractylodes lancea volatile oil mainly contains volatile substances such as β-cineole, atractylin, atractylone, atractylol, and elemol. It not only has a certain killing effect on airborne Mycobacterium tuberculosis and Pseudomonas aeruginosa, but also has a strong killing effect on Escherichia coli and Staphylococcus aureus.

[0023] The volatile oil of cinnamon twigs of this invention can be extracted from the dried tender twigs of cinnamon, a plant of the Lauraceae family. The volatile oil of cinnamon twigs mainly contains volatile substances such as benzaldehyde, phenylpropanal, trans-cinnamaldehyde, and cinnamaldehyde, and has significant antibacterial, sedative, and analgesic effects.

[0024] During the process of experimentation, the inventors discovered that the main active components of Atractylodes lancea volatile oil, such as atractylol, and the main active components of Cinnamaldehyde, such as cinnamaldehyde, in Cinnamomum cassia volatile oil have a synergistic bactericidal effect. When used in a specific ratio, the two can significantly kill and inhibit Staphylococcus aureus, Streptococcus, and anaerobic Streptococcus while reducing the total dosage. The mechanism may be that atractylodes lancea synergistically inhibits bacterial cell wall synthesis, that is, inhibits the synthesis of cell wall peptidoglycan synthase (including transpeptidase, carboxyfetoprotein, and endopeptidase), thereby hindering the synthesis of cell wall peptidoglycan, causing cell wall defects, bacterial rupture and death.

[0025] Although the present invention can also extract plant (volatile) oils such as Atractylodes lancea volatile oil and / or Cinnamomum cassia volatile oil using conventional extraction techniques such as CO2 supercritical (or subcritical) fluid extraction, the present invention preferably achieves rapid industrial-scale extraction of plant oils using the following extraction system.

[0026] Therefore, according to a third aspect of the present invention, a plant (volatile) oil extraction system is also provided, comprising:

[0027] An extractor with a feed port and a discharge port, in which a screw conveyor is installed;

[0028] The first liquid storage tank is selectively connected to the extractor through the first gas-liquid partial circuit and the first siphon partial circuit, respectively;

[0029] The second liquid storage tank is selectively connected to the extractor through the second gas-liquid partial circuit and the second siphon partial circuit, respectively;

[0030] The cooler is located near the extractor in the first gas-liquid section circuit and the second gas-liquid section circuit.

[0031] According to the extraction system of the present invention, the first gas-liquid partial circuit includes a first vertical pipe communicating with the top of the first storage tank, a common vertical pipe communicating with the top of the extractor, and a horizontal pipe communicating with the two and equipped with a valve; the second gas-liquid partial circuit includes a second vertical pipe communicating with the top of the second storage tank, a common vertical pipe communicating with the top of the extractor, and a horizontal pipe communicating with the two and equipped with a valve; and the first siphon partial circuit and the second siphon partial circuit are respectively equipped with valves.

[0032] According to the extraction system of the present invention, the first siphon partial circuit and the second siphon partial circuit each have an upwardly bent portion and their highest point is lower than the top of the extractor.

[0033] The all-natural fruit and vegetable washing liquid of this invention can inhibit and kill bacteria, safely remove dirt, is non-toxic and harmless, green and environmentally friendly, and has no irritation or side effects on the human body. It has a rapid and long-lasting killing effect on common harmful bacteria such as Staphylococcus aureus, Candida albicans, Escherichia coli, and Streptococcus.

[0034] This invention also utilizes a highly efficient (continuous) vegetable oil extraction system, thereby significantly improving vegetable oil production efficiency and enabling the industrial-scale production of pure natural fruit and vegetable detergents. This is unparalleled by conventional laboratory extraction techniques.

[0035] The fruit and vegetable washing liquid formula of this invention combines various natural surfactants, foaming agents, and emulsifiers in an organic way, thereby possessing both excellent bactericidal properties and superior washing and stain removal capabilities. Furthermore, because the fruit and vegetable washing liquid of this invention uses edible raw materials and only requires a small amount of water to rinse, it has significant advantages in terms of health and environmental protection. Attached Figure Description

[0036] Figure 1 This is a schematic diagram of a vegetable oil extraction system (apparatus) according to the present invention. Detailed Implementation

[0037] Vegetable oil extract

[0038] This invention designs a rapid (uninterrupted) vegetable oil extraction system to meet the vegetable oil raw material requirements for the industrial production of fruit and vegetable detergents. In this invention, vegetable oil, essential oil, and volatile oil refer to the same thing, all being extracts of the corresponding plants mentioned below.

[0039] See Figure 1 The vegetable oil extraction system of the present invention includes a first storage tank 10 and a second storage tank 20, a cooler 30 and an extractor 40.

[0040] The bottom of the first storage tank 10 is equipped with a drain pipe 11, on which a valve 12 is mounted. The top of the tank is connected to the top of the extractor 40 via a first gas-liquid partial circuit, and the upper part is connected to the bottom of the extractor 40 via a first siphon partial circuit 50. The first gas-liquid partial circuit includes a first vertical pipe 13 connected to the top of the first storage tank 10, a common vertical pipe 33 connected to the top of the extractor 40, and a horizontal pipe connecting the two and equipped with a valve 14. The first siphon partial circuit 50 is equipped with a valve 51. (The text abruptly ends here.) Figure 1 As shown, the first siphon section circuit 50 has an upwardly bent portion and its highest point is lower than the top of the extractor 40.

[0041] Similarly, the bottom of the second storage tank 20 is provided with a drain pipe 21 on which a valve 22 is installed, and the top is connected to the top of the extractor 40 through a second gas-liquid partial circuit, while the upper part is connected to the bottom of the extractor 40 through a second siphon partial circuit 60. The second gas-liquid partial circuit includes a second vertical pipe 23 connected to the top of the second storage tank 20, a common vertical pipe 33 connected to the top of the extractor 40, and a horizontal pipe connecting the two and equipped with a valve 24. The second siphon partial circuit 60 is equipped with a valve 61. Figure 1 As shown, the first siphon section circuit 60 also has an upwardly bent portion and its highest point is lower than the top of the extractor 40.

[0042] exist Figure 1 In the diagram, the first gas-liquid partial circuit and the second gas-liquid partial circuit share a common vertical pipe 33, which passes through the cooler 30. In an alternative embodiment, the first gas-liquid partial circuit and the second gas-liquid partial circuit may not share a common vertical pipe 33, but each has its own vertical pipe passing through the cooler 30. In this case, valve 14 and valve 24 can be omitted.

[0043] A screw conveyor 44 is installed in the extractor 40 to convey (dry) plant particles or powder fed from the top feed port 41 of the extractor 40 along the length of the extractor (shown horizontally in the diagram) until it reaches the vicinity of the extractor discharge port 42. The powder particles in the screw conveyor 44 will come into direct contact with the liquid in the extractor 40.

[0044] The working principle of the above extraction system is briefly described below.

[0045] First, plant particles or powders, such as Atractylodes lancea root and stem particles, Cinnamomum cassia twig particles, or Clematis chinensis granules, are added through the feed port 41 of the extractor 40, and the screw conveyor 44 is started to spread the plant particles along the horizontal direction of the extractor 40 to the vicinity of the discharge port 42 of the extractor 40.

[0046] Close valves 12 and 22, and then add purified water to the first storage tank 10 and the second storage tank 20, filling the tanks to about two-thirds of their volume.

[0047] Close valves 24 and 61; open valves 14 and 51.

[0048] Start the cooler 30.

[0049] The first storage tank 10 is heated until the pure water inside is kept boiling to continuously generate water vapor.

[0050] The water vapor formed in the first storage tank 10 flows upward through the first vertical pipe 13 and the horizontal pipe, then downward through the common vertical pipe 33, and becomes condensate when passing through the cooler 30 and is introduced into the extractor 40.

[0051] When the liquid level in the extractor 40 exceeds the highest point of the first siphon circuit 50, the extract will return to the first storage tank 10 through the first siphon circuit 50.

[0052] When the extractant through the first siphon circuit 50 becomes essentially colorless, heating of the first storage tank 10 is stopped, and the screw conveyor 44 is started to discharge the wet plant powder therein from the extractor 40 through the outlet 42.

[0053] Simultaneously or immediately following the discharge action of the screw conveyor 44, (fresh) plant particles are added through the feed port 41 of the extractor 40, and still pass through the screw conveyor 44 until they reach the vicinity of the discharge port 42 of the extractor 40.

[0054] Close valves 14 and 51; open valves 24 and 61.

[0055] The second storage tank 20 is heated to perform the same extraction process.

[0056] Open valve 12 to drain the extract from first storage tank 10 through drain pipe 11, and then separate it into distilled water and vegetable (extracted) oil.

[0057] As described above, the first storage tank 10 and the second storage tank 20 work alternately, and are coordinated with the rapid conveying / discharging of the screw conveyor 44, thereby realizing the (uninterrupted) rapid industrial-scale extraction of vegetable oil.

[0058] Preparation of fruit and vegetable washing liquid

[0059] Mix the purified water, sodium citrate, and baking soda thoroughly.

[0060] Then add cocamidoyl DEA, sodium lauryl ether sulfate, sodium dodecyl sulfate (TEA), cocamidopropyl betaine, glycerin, and flavoring, respectively.

[0061] Stir to dissolve completely; and

[0062] Finally, add Atractylodes lancea oil, Cinnamomum cassia oil, and optionally Clematis chinensis oil, and stir well until it becomes transparent and clear before bottling.

[0063] In the above-mentioned additives, DEA represents diethylamino and TEA represents triethylamino.

[0101] Quantitative sterilization test of suspension

[0102] (1) Select three strains of Staphylococcus aureus, Streptococcus and anaerobic Streptococcus to prepare experimental bacterial suspensions according to the disinfection technical specifications, with a concentration of 1×108cfu / ml~5×108cfu / ml.

[0103] (2) Add 0.5 ml of bacterial suspension to the sterile test tube for the detoxification test, then add 0.5 ml of organic interfering substance, mix well, place in a water bath at 20℃±1℃ for 5 min, and then use a sterile pipette to draw 4.0 ml of the washing solution prepared in each example and comparative example and inject it into the tube. Mix quickly and start timing immediately.

[0104] (3) After the test bacteria and washing solution have interacted for each predetermined time, take 0.5 ml of the mixture of test bacteria and washing solution and add it to 4.5 ml of sterilized neutralizing agent and mix well.

[0105] (4) After the mixture of test bacteria and washing solution in each tube is neutralized and reacted for 10 minutes, 1.0 ml of sample solution is taken out and the number of viable bacteria is determined according to the viable bacteria culture and counting method. Each sample solution is inoculated into 2 petri dishes. If there are many colonies growing on the plates, serial 10-fold dilutions can be performed before viable bacteria culture and counting.

[0106] (5) At the same time, a parallel test was conducted using a diluent instead of a washing solution as a positive control.

[0107] (6) All test samples were cultured in an incubator at 37°C. The bacterial vegetative cells were cultured for 48 hours to observe the final results; the bacterial spores were cultured for 72 hours to observe the final results.

[0108] (7) The experiment was repeated 3 times. The viable bacterial concentration (cfu / ml) of each group was calculated and converted to logarithmic value (N). Then, the kill log value was calculated using the following formula:

[0109] Log kill count (KL) = Logarithm of average viable bacterial concentration in the control group (No) - Logarithm of viable bacterial concentration in the experimental group (Nx)

[0110] The experimental results are shown in Table 1.

[0111] Table 1: Results of quantitative bactericidal test of suspension

[0112]

[0113]

[0114] The above bactericidal test results show that:

[0115] High concentrations of Atractylodes lancea oil and Cinnamomum cassia oil, used alone, exhibit strong bactericidal effects against Staphylococcus aureus, with a log reduction (KL) reaching as high as 5.14. However, their log reduction effects against Streptococcus and anaerobic Streptococcus are relatively poor (both below 5.0). Based on the screening results of Examples 1-8, the combined use of these two oils demonstrates a synergistic effect among the main active components, achieving significant bactericidal effects against Staphylococcus aureus, Streptococcus, and anaerobic Streptococcus while reducing the dosage. For example, in the quantitative bactericidal tests of suspensions in Comparative Examples 1-4, the average logarithmic kill values ​​of the three bacteria when using 1.0% and 1.5% concentrations of Atractylodes lancea volatile oil fruit and vegetable wash solutions alone were 3.93 and 4.41, respectively; the average logarithmic kill values ​​of the three bacteria when using 0.8% and 1.2% concentrations of Cinnamomum cassia volatile oil fruit and vegetable wash solutions alone were 4.13 and 4.45, respectively. When the two were used together, the average logarithmic kill value of the three bacteria was greater than 5.0 regardless of the concentration adjustment, fully demonstrating that Atractylodes lancea oil and Cinnamomum cassia oil have a synergistic bactericidal effect. Examples 9-12 show that adding a small amount of Atractylodes lancea oil can further enhance the bactericidal effect.

[0116] In addition, 20 men and 20 women aged 18-60 with normal physical condition were selected for skin irritation tests. The participants used the fruit and vegetable washing liquid of Example 10 to wash fruits and vegetables 3 times a day for 5 minutes each time. During the test, they did not come into contact with other chemical products or perform any additional hand care. After one week, two weeks and one month, the statistical results showed that, without any skin care, the use of the fruit and vegetable washing liquid of this invention had no side effects on the human body, regardless of gender or age. That is, the skin did not experience any irritation, itching or redness.
