Description
[ field of technology ]
The invention relates to a microemulsion fruit and vegetable detergent, belonging to the technical field of daily chemical products.
[ background Art ]
With the progress of society and the increase of people's attention to health, vegetables and fruits have taken an increasingly important role in people's diet structure, and fresh vegetables and fruits are important sources of essential exogenous nutrients such as vitamins, minerals and dietary fibers necessary for people's daily life. In order to ensure the yield of fruits and vegetables, farmers often apply a lot of pesticides, and the heavy metal enrichment of the fruits and vegetables is increased due to pollution of water sources and soil. The problem of pesticide residue and excessive heavy metal on vegetables and fruits causes concern for more and more consumers. After the human body eats fruits and vegetables containing pesticides or heavy metal ions exceeding the standard, toxic substances accumulate in the human body for a long time to cause various chronic diseases, and more troublesome is that some pesticide residues have genetic toxicity. To address this problem, many consumers choose a fruit and vegetable cleaning agent to clean the fruit and vegetable. Various fruit and vegetable cleaning products appear in the market, and fruit and vegetable detergent is a mainstream product, but because a lot of products have lower technical content, if only a few artificial synthetic surfactants are added with auxiliary agents to be simply compounded, the selected petrochemical raw materials are not safe enough, and the fruit and vegetable detergent has no obvious effect on pesticide removal effect after use, has serious problems such as secondary pollution and the like, and has potential safety hazard. The research and development of natural raw materials for preparing efficient and safe fruit and vegetable detergent has become a folk problem to be solved urgently.
[ invention ]
The invention aims to overcome the defects of the prior art and provide the microemulsion fruit and vegetable detergent which has good pesticide residue removing effect and stable and safe system.
The invention adopts the following technical scheme to realize the aim:
the micro-emulsion fruit and vegetable detergent is characterized by comprising the following components in percentage by mass:
the invention relates to a microemulsion fruit and vegetable detergent which is characterized by further comprising the following components in percentage by mass:
0.5 to 1 percent of micro-nano shell powder
Proper amount of auxiliary agent
Water was added to 100%.
In the invention, the auxiliary agent comprises one or more of glycerol, pH regulator, essence and preservative.
The invention relates to a microemulsion fruit and vegetable detergent, which is prepared by the following steps:
a. uniformly mixing limonene, alkyl glucoside, coconut oil derivatives, sucrose fatty acid ester and corresponding water, and heating to 65-75 ℃ to dissolve and transparent to form a transparent microemulsion phase;
b. pre-dissolving preservative and/or essence and part of water;
c. heating glycerin, micro-nano shell components and the balance of water to 80-90 ℃ under stirring to dissolve and transparent to form a water phase, and preserving heat;
d. slowly adding the water phase prepared in the step c into the three-phase micro-emulsion limonene phase prepared in the step a, emulsifying, homogenizing, adding a pH regulator to regulate the pH value, cooling to 45 ℃, adding a pre-dissolved preservative and/or essence, uniformly stirring, cooling and discharging.
The microemulsion technology is a system which is prepared by a certain technological method through an oil phase, a water phase, a surfactant and a cosurfactant phase and has the emulsion particle size of 10-100nm, and the microemulsion system has ultralow interfacial tension, large solubilization capacity, small particle size and excellent thermodynamic stability, and can improve the capability of dissolving pesticides to remove pesticides to a large extent.
Limonene, which is widely found in natural plant peel, is generally extracted from discarded citrus peel. Limonene can be used as an antioxidant and a preservative in food additives, is a natural excellent surfactant in the field of daily chemicals, and has good fat-dissolving and decontamination capability. Limonene has good antibacterial activity, has the potential of becoming a natural preservative, has good biodegradability and does not cause any pollution to the environment.
The micro-nano shell powder is powder obtained by crushing shells through micro-nano, wherein 95% of the main components of the micro-nano shell powder are calcium carbonate, and a small amount of amino acid and polysaccharide substances. The porous fibrous double helix structure has the effects of adsorption and decomposition. In addition, the shell powder has strong antibacterial and bactericidal effects on escherichia coli. The harmful components have antiseptic function.
The invention prepares a three-phase microemulsion limonene system by using plant-source surfactant, cosurfactant, plant-source grease limonene, water and other raw materials through a microemulsion technology. As the emulsion grain size of the microemulsion fruit and vegetable detergent is smaller than that of the general detergent, the microemulsion fruit and vegetable detergent can interact with pesticides and heavy metals on fruits and vegetables more fully and can be dissolved and removed from the fruits and vegetables.
Compared with the prior art, the invention has the following advantages:
the product of the invention is stable and safe, has excellent double cleaning performances of physical adsorption removal and chemical dissolution removal for dirt, pesticide residue and heavy metal on the surfaces of fruits and vegetables, and also has sterilization and bacteriostasis effects.
[ detailed description ] of the invention
The invention is described in further detail below in connection with specific examples:
the invention discloses a microemulsion fruit and vegetable detergent, which comprises the following components in percentage by mass:
the three-phase microemulsion limonene system (three-phase microemulsion limonene phase) was optimized as follows, and the specific orthogonal table design is shown in table 1.
Table 1: mass ratio of each component of three-phase microemulsion limonene phase
The results of the orthogonal test are shown in Table 2, and the results of the analysis of variance are shown in Table 3.
Table 2: orthogonal test design and results
TABLE 3 orthogonal test analysis of variance table
Note that: * P <0.1
In test nos. 1 to 9, the particle size of the prepared three-phase microemulsion limonene system is the smallest under the main raw material proportion of test No. 3, and the proportion is A 1 B 3 C 3 D 3 Namely, the mass ratio of limonene, alkyl glucoside, coconut oil derivative and sucrose fatty acid ester is 9:10:9:7, the particle size of the obtained three-phase microemulsion limonene system is 59.7nm. The average value results corresponding to the usage conditions of each component in Table 2 are as follows: when the mass ratio of limonene, alkyl glucoside, coconut oil derivative and sucrose fatty acid ester is 12, 10, 9 and 7, the average value of the particle diameters of the corresponding microemulsions is the smallest, namely A 2 B 3 C 3 D 3 . Therefore, experiments are carried out under the condition, and the particle size of the obtained three-phase micro-emulsion limonene system is 60.1nm. Considering that the cleaning ability of a three-phase microemulsion limonene system is important, in addition to particle size, the amount of limonene is also an important factor. Under the same conditions, the content of limonene is increased, and the cleaning capability is enhanced. Considering two important factors determining the cleaning capacity of the system, namely limonene and particle size, the optimal dosage is selected as follows: the dosage ratio of limonene, alkyl glucoside, coconut oil derivative and sucrose fatty acid ester is 12, 10, 9 and 7.
The primary and secondary order of analyzing the influence of the consumption of 4 raw materials on the particle size of the prepared three-phase micro-emulsion limonene system micro-emulsion according to the extremely poor results in table 2 is as follows: b > A > D > C, show that C has small influence on the particle size of the prepared three-phase microemulsion limonene system microemulsion, so C is selected as an error column of orthogonal test variance analysis. From the analysis of variance results table 3, it is known that a and B have significant meanings under the condition of a=0.1, and on the other hand, a and B play a decisive role in the formation of the microemulsion, and the particle size of the microemulsion becomes significantly smaller under the action of a and B. However, C, D has no significant effect on the particle size of the three-phase microemulsion limonene system, because the two are mainly auxiliary effects and do not play a decisive role in the system.
In the process production, the raw material saving is significant because both A and B have significance, the important factors of the cleaning capability of the system are comprehensively considered by comprehensively considering the limonene and the particle size, and the C, D influence on the particle size of the three-phase microemulsion limonene system is not significant, thereby keeping A 2 、B 3 On the premise of the raw material condition, the raw material consumption of C, D is reduced, the possibility of the scheme is verified by test number 6 in the orthogonal test result, and the method is characterized in that 2 B 3 C 1 D 2 The particle size of the obtained three-phase microemulsion system is 60.4nm under the coordination of the raw materials. In order to save the cost of raw materials, the finally determined optimization process scheme of the test is as follows: a is that 2 B 3 C 1 D 2 。
