Influence of the different DE value maltodextrins to water-soluble plant essential oil disinfection agent stability
Maltodextrin is also referred to as water-soluble dextrin, makees raw material with each kind of starch and is made after enzymatic hydrolysis, according to hydrolysis journey
Degree, DE value have emulsification well, thickening and stabilization, are the excellent carriers of various lyophobic dusts generally between 5-20.
Cyclodextrin is the cyclic polymer being formed by connecting by 6 and 6 or more glucose units, is in hollow circle tube, has external parent
The characteristic of water, inner hydrophobic can form inclusion compound with many hydrophobic guest molecules, so as to change the reason of guest molecule
Change property, such as solubility, volatility and chemical property.
Wherein, the disinfectant as made from embodiment 3, embodiment 4, comparative example 1, comparative example 2 be respectively disinfectant A, B,
C, D is placed and stands observation stability at room temperature, the results are shown in Table 1.As can be seen from the table, the lower (DE of maltodextrin DE value
For 5 or 10) when, disinfectant obtained has good stability, place at room temperature 30 days it is still not stratified, and DE value is greater than
When 10, obvious layering in placement 10 days or more, possible cause is that the DE value of maltodextrin is higher, and hydrolysis degree is higher, for planting
The stability of object essential oil is poor.
Influence of the 1 difference DE value maltodextrin of table to water-soluble plant essential oil disinfection agent stability
The influence of cyclodextrins for water soluble plants essential oil disinfectant stability
Common cyclodextrin is to connect the α-to be formed, β-and gamma-cyclodextrin with 8 glucose units with 6,7, these three rings
Dextrin is also at present industrially using most cyclodextrin.They can include the change of different molecular size because of cavity size difference
Close object or group.
Wherein, it is respectively E, F, G that disinfectant, which is made, in comparative example 3, comparative example 4 and comparative example 5 respectively, is placed at room temperature
Observation stability is stood, the results are shown in Table 2.As can be seen from the table, a kind of cyclodextrin and maltodextrin (DE=10) are selected to carry
When body, it will appear delamination within placement 30 days or more, stability is worse than 3 kinds of mixing cyclodextrin.Therefore, by maltodextrin and 3 kinds
Cyclodextrin (α-, β-and gamma-cyclodextrin) is mixed collectively as the carrier of plants essential oil, good synergy may be played, it is right
There is apparent improvement in the dissolubility and stability of plants essential oil.
The influence of the different cyclodextrins for water soluble plants essential oil disinfectant stability of table 2
Water-soluble plant essential oil disinfection agent stability made from different plants essential oils
Disinfectant H, I, J, K are made respectively by embodiment 5-8, is placed and stands observation stability, discovery at room temperature
It places 30 days and does not occur lamination, illustrate that the system has good stability for different plants essential oils.Meanwhile with appoint
Meaning ratio water dilutes disinfectant, and floating oil phenomenon does not occur, places 30 days also without lamination, illustrates to have good water-soluble
Property.
Fungistatic effect and its fungistatic effect stability
Disinfectant L is made by embodiment 9, by disinfectant B, disinfectant K and disinfectant L and different microorganisms (large intestine bar
Bacterium, staphylococcus aureus, Candida albicans) mixing 1min, microorganism bacteriostatic experiment is carried out, the results are shown in Table 3.It can be with from table
Find out, 3 kinds of disinfectants mix 1min with microorganism, and for bacteriostasis rate up to 99% or more, bactericidal effect is strong and efficient.Meanwhile to this 3 kinds
Disinfectant carries out antimicrobial stability experiment, as a result, it has been found that, this 3 kinds of disinfectants all have good antimicrobial stability.
3 disinfectant bacteriostatic experiment result of table
Note: Escherichia coli, staphylococcus aureus, Candida albicans bacteriostatic experiment and antimicrobial stability experiment are by " disinfection
Technical specification (version in 2002) " it carries out.
Above-mentioned preferable possible embodiments only of the invention, are not limitations of the present invention, the present invention is also not limited to above-mentioned
Citing, those skilled in the art, within the essential scope of the present invention, made variations, modifications, additions or substitutions,
Also it should belong to protection scope of the present invention.
