Description

Green tableware washing liquid and preparation method thereof

Technical Field

The invention relates to a tableware washing liquid prepared from pure natural plant extract or essential oil.

Background

Along with the continuous improvement of the living standard of people, the requirements of people on sanitation are also higher and higher, and whether tableware is clean or not directly influences the physical health of people. In the catering industry, washing and disinfection of various tableware is an important task, and residues such as calcium, oil dirt, sugar dirt, starch and the like are often accumulated, and if the residues are not cleaned and disinfected in time, pollution, corrosion and propagation of toxic bacteria of food equipment and appliances are caused. Therefore, the washing liquid with strong cleaning power and good sterilization effect is needed to be timely decontaminated. At present, the tableware cleaning agent has various varieties, most of detergents are prepared from chemical raw materials, and the tableware cleaning agent can hurt the skin of hands after long-term use of the tableware cleaning agent for washing cups, bowls, dishes and other devices, especially the tableware is not washed cleanly, and the residual cleaning agent can enter human bodies along with food when the tableware cleaning agent is used again, so that the health of the human bodies is affected.

Disclosure of Invention

The invention aims to provide a tableware washing liquid for sterilization, disinfection and safe decontamination.

According to a first aspect of the present invention there is provided a dishwashing liquid comprising: 1.0 to 1.5 percent of rhizoma atractylodis volatile oil, 0.8 to 1.2 percent of cassia twig volatile oil, 0.1 to 0.2 percent of sodium citrate, 0.05 to 0.06 percent of soda, 3 to 4 percent of cocamide DEA, 8 to 9 percent of sodium lauryl ether sulfate, 15 to 18 percent of sodium dodecyl sulfate, 3 to 5 percent of cocamidopropyl betaine, 2 to 3 percent of glycerol and 1 to 1.5 percent of essence.

According to a preferred embodiment of the present invention, the dishwashing liquid may comprise: 1.0 to 1.2 percent of rhizoma atractylodis volatile oil, 0.8 to 1.0 percent of cassia twig volatile oil, 0.1 to 0.2 percent of sodium citrate, 0.05 to 0.06 percent of soda, 3 to 4 percent of cocamide DEA, 8 to 9 percent of sodium lauryl ether sulfate, 15 to 18 percent of sodium dodecyl sulfate, 3 to 5 percent of cocamidopropyl betaine, 2 to 3 percent of glycerol and 1 to 1.5 percent of essence.

According to a further preferred embodiment of the present invention, the dishwashing liquid may comprise: rhizoma Atractylodis volatile oil: 1.0% -1.5%, and ramulus Cinnamomi volatile oil: 0.8% -1.2%, garden balsam oil: 0.1 to 0.3 percent, 0.1 to 0.2 percent of sodium citrate, 0.05 to 0.06 percent of soda, 3 to 4 percent of cocamide DEA, 8 to 9 percent of sodium lauryl ether sulfate, 15 to 18 percent of sodium dodecyl sulfate, 3 to 5 percent of cocamidopropyl betaine, 2 to 3 percent of glycerol and 1 to 1.5 percent of essence. The addition of small amounts of garden balsam (drug Qu Cao) oil can further shorten the kill time and improve the bactericidal effect, either in relation to the synergistic effect brought about by its permeability properties, or in relation to its auxiliary bactericidal properties.

According to an embodiment of the present invention, the balance of the dishwashing liquid is preferably purified water.

According to a second aspect of the present invention there is provided a method of producing a dishwashing liquid as described above, comprising:

mixing purified water, sodium citrate and soda uniformly;

then respectively adding cocamide DEA, sodium laureth sulfate, sodium dodecyl sulfate, cocamidopropyl betaine, glycerol and essence;

stirring to fully dissolve the components; and

finally adding the atractylis oil, the cassia twig oil and the optional garden balsam oil, and uniformly stirring.

According to the production method of the present invention, the atractylis oil and/or cassia twig oil and/or garden balsam oil are preferably prepared continuously by the following processes:

adding rhizoma Atractylodis rhizome powder and/or ramulus Cinnamomi powder and/or herba Speranskiae Tuberculatae powder into an extractor equipped with screw conveyor;

heating a first liquid storage tank filled with purified water to generate water vapor;

condensing the water vapor into liquid water by a cooler, and then introducing the liquid water into an extractor to submerge rhizome powder of rhizoma atractylodis and/or cassia twig powder and/or garden balsam stem powder;

when the liquid level in the extractor is higher than the highest point of a siphon pipe connecting the extractor and the first liquid storage tank, extracting liquid in the extractor automatically enters the first liquid storage tank through the siphon pipe;

when the extracting solution in the extractor becomes colorless, starting a screw conveyer in the extractor to discharge rhizoma atractylodis rhizome wet powder and/or cassia twig wet powder and/or garden balsam stem wet powder out of the extractor, and simultaneously adding (fresh) rhizoma atractylodis rhizome powder and/or cassia twig powder and/or garden balsam stem powder into the extractor;

stopping heating the first liquid storage tank and simultaneously starting the second liquid storage tank to continue the steps; and

separating the extractive solution in the first liquid storage tank to obtain rhizoma Atractylodis oil and/or ramulus Cinnamomi oil and/or herba Speranskiae Tuberculatae oil.

According to a preferred embodiment of the present invention, the plant oil extraction process is performed after the rhizome powder of rhizoma Atractylodis and the powder of ramulus Cinnamomi and optionally the powder of herba speranskiae tuberculatae are mixed in proportion. In this case, since the active plant components undergo a high-temperature reaction bonding process at the time of extraction, a stronger synergistic bactericidal effect can be formed.

The atractylis lancea (volatile) oil of the present invention can be obtained by extracting dried rhizome of atractylis lancea or atractylis ovata belonging to the genus atractylis of the family Compositae. The rhizoma Atractylodis volatile oil mainly contains volatile substances such as beta-eucalyptol, atractylone, atractylol, elemene, etc. Not only has a certain killing effect on mycobacterium tuberculosis, pseudomonas aeruginosa and the like in the air, but also has a very strong killing effect on escherichia coli and staphylococcus aureus.

The (cassia twig) volatile oil can be extracted from dried twigs of cinnamon belonging to the family Lauraceae. The cassia twig volatile oil mainly contains volatile substances such as benzaldehyde, phenylpropionaldehyde, trans-cinnamaldehyde, cinnamaldehyde and the like, and has remarkable antibacterial, sedative and analgesic effects.

The inventor finds that the main active ingredients in the rhizoma atractylodis volatile oil, such as atractylol, and the main active ingredients in the cassia twig volatile oil, such as cinnamaldehyde, have synergistic bactericidal effect, and the main active ingredients in the rhizoma atractylodis volatile oil, such as cinnamaldehyde, are combined in a specific proportion, so that the total dosage is reduced, and meanwhile, the main active ingredients can have obvious killing and inhibiting effects on staphylococcus aureus, streptococcus and anaerobic streptococcus, or the mechanism is that the atractylol and the cinnamaldehyde synergistically inhibit the synthesis of bacterial cell walls, namely inhibit the synthesis of cell wall mucin synthetase (including transpeptidase, carboxyfetase and endopeptidase), thereby inhibiting the synthesis of cell wall peptidoglycan, leading cell walls to defect and cell body rupture death.

Although the invention may also be practiced with conventional extraction techniques such as CO ₂ Supercritical (or subcritical) fluid extraction is used to extract vegetable (volatile) oils such as atractylis ovata volatile oil and/or cassia twig volatile oil, but the present invention preferably achieves rapid commercial scale extraction of vegetable oils by the following extraction system.

Thus, according to a third aspect of the present invention there is also provided a plant (volatile) oil extraction system comprising:

an extractor having a feed inlet and a discharge outlet, wherein a screw conveyor is provided;

the first liquid storage tank is selectively communicated with the extractor through a first gas-liquid part loop and a first siphon part loop respectively;

the second liquid storage tank is selectively communicated with the extractor through a second gas-liquid part loop and a second siphon part loop respectively;

and the cooler is arranged on the first gas-liquid part loop and the second gas-liquid part loop close to the extractor.

The extraction system according to the invention, wherein the first gas-liquid partial circuit comprises a first vertical line communicating with the top of the first liquid storage tank, a common vertical line communicating with the top of the extractor, and a horizontal line communicating both and provided with a valve; the second gas-liquid part loop comprises a second vertical pipeline communicated with the top of the second liquid storage tank, a common vertical pipeline communicated with the top of the extractor and a horizontal pipeline communicated with the first vertical pipeline and the top of the extractor and provided with a valve; and the first siphon part loop and the second siphon part loop are respectively provided with valves.

According to the extraction system of the present invention, the first siphon part circuit and the second siphon part circuit have upward bending portions respectively and the highest point thereof is lower than the top of the extractor.

The green tableware washing liquid can kill bacteria, is nontoxic and harmless, is green and environment-friendly, is safe to decontaminate, has no stimulation and side effect on human bodies, and has a quick and durable killing effect on common harmful bacteria such as staphylococcus aureus, candida albicans, escherichia coli, streptococcus and the like.

The invention also uses a high-efficiency (uninterrupted) vegetable oil extraction system, thereby greatly improving the vegetable oil production efficiency and realizing the industrialized mass production of the green tableware washing liquid. This is not comparable to conventional laboratory extraction techniques.

The tableware cleaning solution formula disclosed by the invention organically combines a plurality of auxiliary agents, so that the tableware cleaning solution has excellent sterilizing performance and excellent washing and decontamination capability, and has no irritation to skin. As the tableware cleaning solution adopts edible raw materials and is only washed by a little water, the tableware cleaning solution has great advantages in the aspects of health, environmental protection and water saving.

Detailed Description

Vegetable oil extraction

The invention designs a rapid (uninterrupted) vegetable oil extraction system to meet the vegetable oil raw materials required in the industrial production of tableware washing liquid. In the invention, the vegetable oil, the essential oil and the volatile oil are the same, and are all the extracting solutions of the corresponding plants.

Referring to fig. 1, the vegetable oil extraction system of the present invention includes first and second

liquid storage tanks

10 and 20, a cooler 30, and an extractor 40.

The bottom of the first liquid storage tank 10 is provided with a liquid discharge pipe 11 on which a valve 12 is installed, the top is communicated with the top of the extractor 40 through a first gas-liquid part loop, and the upper side is communicated with the bottom of the extractor 40 through a first siphon part loop 50. The first gas-liquid partial circuit comprises a first vertical line 13 communicating with the top of the first liquid storage tank 10, a common vertical line 33 communicating with the top of the extractor 40, and a horizontal line communicating both and provided with a valve 14. The first siphon part circuit 50 is provided with a valve 51. As shown in fig. 1, the first siphon portion circuit 50 has an upwardly turned portion with its highest point lower than the top of the extractor 40.

Similarly, the bottom of the second liquid storage tank 20 is provided with a liquid discharge pipe 21 on which a valve 22 is mounted, the top is communicated with the top of the extractor 40 through a second gas-liquid partial circuit, and the upper side is communicated with the bottom of the extractor 40 through a second siphon partial circuit 60. The second gas-liquid partial circuit comprises a second vertical line 23 communicating with the top of the second liquid storage tank 20, a common vertical line 33 communicating with the top of the extractor 40, and a horizontal line communicating both and provided with a valve 24. The second siphon part circuit 60 is provided with a valve 61. As shown in fig. 1, the first siphon portion circuit 60 also has an upwardly turned portion with its highest point below the top of the extractor 40.

In fig. 1, the first and second gas-liquid partial circuits are shown with a common vertical line 33, the common vertical line 33 passing through the cooler 30. In alternative embodiments, the first and second gas-liquid partial circuits may also not have a common vertical line 33, but rather each have a vertical line through the cooler 30, in which case the valve 14 and the valve 24 may be omitted.

An auger 44 is mounted in the extractor 40 to convey the (dried) plant particles or powder fed from the top feed port 41 of the extractor 40 along the length of the extractor (shown as horizontal) until near the extractor discharge port 42. The powder particles in the screw conveyor 44 will be in direct contact with the liquid in the extractor 40.

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

First, plant particles or powder such as rhizome particles of rhizoma Atractylodis or ramulus Cinnamomi particles or herba speranskiae tuberculatae particles are added through a feed port 41 of the extractor 40, and a screw conveyor 44 is started to spread the plant particles in the horizontal direction of the extractor 40 to the vicinity of a discharge port 42 of the extractor 40.

Valve 12 and valve 22 are closed and then purified water is added to the first and second

fluid reservoirs

10 and 20, respectively, in an amount of about two-thirds of the volume of the reservoirs.

Closing valve 24 and valve 61;

valves

14 and 51 are opened.

The chiller 30 is started.

The first liquid storage tank 10 is heated until and maintaining pure water therein continuously boiling to continuously form water vapor.

The water vapor formed in the first liquid storage tank 10 passes upward through the first vertical line 13 and the horizontal line, then downward through the common vertical line 33, and becomes condensed water when passing through the cooler 30, and is introduced into the extractor 40.

When the liquid level in the extractor 40 exceeds the highest point of the first siphon portion circuit 50, the extract therein will return to the first holding tank 10 through the first siphon portion circuit 50.

When the extract passing through the first siphon portion circuit 50 becomes substantially colorless, heating of the first holding tank 10 is stopped, and the screw conveyor 44 is started to discharge the plant wet powder therein out of the extractor 40 via the discharge port 42.

Simultaneously or immediately following the discharge action of the screw conveyor 44 described above, the (fresh) plant particles are added through the feed opening 41 of the extractor 40, still through the screw conveyor 44 to the vicinity of the discharge opening 42 of the extractor 40.

Closing valve 14 and valve 51;

valves

24 and 61 are opened.

The second tank 20 is heated to perform the same extraction process.

The valve 12 is opened to drain the extract in the first tank 10 through the drain pipe 11, and then separated into distilled water and vegetable (extracted) oil.

As described above, the first tank 10 and the second tank 20 are alternately operated in conjunction with the rapid delivery/discharge of the screw conveyor 44, thereby achieving (uninterrupted) rapid industrial-scale extraction of the vegetable oil.

Quantitative sterilization test of suspension

(1) The three strains of staphylococcus aureus, streptococcus and anaerobic streptococcus are selected to prepare experimental bacterial suspension according to the disinfection technical specification, and the concentration is 1 multiplied by 108cfu/ml to 5 multiplied by 108cfu/ml.

(2) The sterile large test tube for the detoxification test is added with 0.5ml of the bacterial suspension for the test, then 0.5ml of the organic interfering substance is added, the mixture is uniformly mixed, the mixture is placed in a water bath with the temperature of 20+/-1 ℃ for 5min, and then 4.0ml of the washing liquid prepared in each example and comparative example is sucked by a sterile suction tube and injected into the water bath, and the mixture is quickly mixed and immediately clocked.

(3) And respectively sucking 0.5ml of mixed solution of the test bacteria and the washing liquid to be interacted with each other until each preset time, adding the mixed solution into 4.5ml of sterilized neutralizer, and uniformly mixing.

(4) And (3) respectively sucking 1.0ml of sample liquid after the mixed liquid of each tube of test bacteria and the washing liquid is subjected to the action of a neutralizing agent for 10min, and measuring the number of viable bacteria according to a viable bacteria culture counting method, wherein each tube of sample liquid is inoculated with 2 dishes. If the number of colonies growing on the plate is large, serial 10-fold dilution can be performed, and viable bacteria culture counting can be performed.

(5) Meanwhile, the diluent is used for replacing the washing liquid, and a parallel test is performed to serve as a positive control.

(6) All test specimens were cultivated in a 37 ℃ incubator and the final results were observed for 48h of bacterial propagule cultivation; the bacterial spores were cultured for 72 hours to observe the final result.

(7) The test was repeated 3 times, the viable bacteria concentration (cfu/ml) of each group was calculated and converted into a logarithmic value (N), and then the killing logarithmic value was calculated as follows:

log value of killing log value (KL) =log value of average viable bacteria concentration of control group (No) -log value of viable bacteria concentration of test group (Nx)

The test results are shown in Table 1.

Table 1: quantitative sterilization test results of suspension

From the above sterilization test results, it is shown that:

the high-concentration atractylis oil and cassia twig oil have stronger killing effect on staphylococcus aureus when being singly used, the killing logarithmic value (KL) can be even as high as 5.14, but the killing logarithmic value on streptococcus and anaerobic streptococcus is poorer (both lower than 5.0). From the screening results of examples 1-8, the main active ingredients in the rhizoma atractylodis volatile oil and the cassia twig volatile oil have synergistic effect, so that the main active ingredients have obvious killing effect on staphylococcus aureus, streptococcus and anaerobic streptococcus while reducing the dosage. For example, in the quantitative sterilization test of the suspensions of comparative examples 1 to 4, the combined average sterilization log values of three bacteria of the atractylis ovata volatile oil dishwashing liquid with concentrations of 1.0% and 1.5% are respectively 3.93 and 4.41, and the combined average sterilization log values of three bacteria of the cassia twig volatile oil dishwashing liquid with concentrations of 0.8% and 1.2% are respectively 4.13 and 4.45; when the two are mixed for use, the comprehensive average killing logarithmic value of the three bacteria is more than 5.0 no matter how the concentration is regulated, which fully shows that the atractylis oil and the cassia twig oil have synergistic sterilizing effect. Examples 9-12 show that the addition of small amounts of the herb oil further synergistically enhances the bactericidal effect.

In addition, 20 men and women with normal physical conditions and ages 18-60 were selected for skin irritation test, and the test subjects used the dishwashing liquid of example 10 to perform dishwashing 3 times per day for 5 minutes without contact with other chemical products during the test, without additional hand skin care, for one week, two weeks, and one month post statistics, which indicated that: on the premise of not caring skin, no matter men or women or people of all ages, the tableware washing liquid has no side effect on human bodies, namely no irritation, itching and redness of skin.
