Nepal gold ester is methyl esters or ethyl ester or propyl ester or any mixture, and emulsifying agent is 20～80% span 20 and 20～80% polysorbas20.
Generally the preservative agent that uses in food service industry enterprise produces has benzoic acid, Sodium Benzoate, calcium propionate, calcium propionate potassium, 25 kinds of calcium propionates etc., need colourless according to acetate fiber with preservative agent, tasteless, nontoxic principle, the present invention is by the cultivation to the mineral oil microorganism, and select seven kinds of common food preservatives for use: sorbic acid, potassium sorbate, dehydroactic acid, propylparaben, Sodium Benzoate, calcium propionate, dimethyl fumarate, carry out bacteriostatic experiment and the comparison of mineral oil microorganism, thereby selected bacteriostatic agent, cultivation and the bacteriostatic experiment thereof of mineral oil microorganism mainly contain dual mode: one is solid culture, be with the main nutrition of an amount of mineral oil as growth of microorganism, preparation solid agar medium, mineral oil has been polluted in the dilution coating, in 30 ℃ of constant temperature, cultivated 5～10 days, when bacteriostatic experiment, in solid medium, add certain density bacteriostatic agent, and then mineral oil has been polluted in coating, the clump count that grows with every flat board is as the evaluation index of certain bacteriostatic agent condition fungistatic effect, simultaneously, finish test with bacteria culture media; Two is Liquid Culture, be the mineral oil inoculation mineral oil that is fit to concentration to have polluted, at 30 ℃, cultivated 30 days on the shaking table of 200rpm, during bacteriostatic experiment, in cultivating liquid-based, add certain density bacteriostatic agent, polluted mineral oil to wherein inoculating, and with the evaluation index of liquid culture dry cell weight as fungistatic effect, following table is proterties, dissolution properties, effect and pH value and the range of application of seven kinds of food-grade bacteriostatic agents of employing in the experiment:
When carrying out the screening of bacteriostatic agent, need carry out the separation and Culture of microorganism in the mineral oil earlier, by contrast ratio is carried out in the cultivation of the mineral oil microorganism of adding bacteriostatic agent and the cultivation of not adding the mineral oil microorganism of bacteriostatic agent, mineral oil microorganism to two kinds of sources inoculates earlier: one is mineral oil flat-plate bacterial colony dilution, be about to the cultivation of mineral oil plate isolation and obtain bacterium colony, break up with the dilution of 100mL sterilized water, this solution is used for inoculation; Two for polluting the mineral oil dilution, promptly polluted the mineral oil sample directly with 200 times of aseptic dilution waters, gained solution is used for inoculation, under these two kinds of inoculation conditions, to bacteriostatic agent by the maximum safe dose of use, come the fungistatic effect of comparison bacteriostatic agent with reference to control group, the mineral oil microorganism of control group for not adding bacteriostatic agent, as shown in Table 1 and Table 2:
The comparison of each bacteriostatic agent fungistatic effect when table 1 is solid culture
The comparison of each bacteriostatic agent fungistatic effect when table 2 is Liquid Culture
With reference to table 1 and table 2, discovery is under two kinds of inoculation conditions, concentration is the Sodium Benzoate of 2.5g/L, 0.05g/L dimethyl fumarate, 2.5g/L calcium propionate and Nepal of 0.5g/L gold ester can suppress the growth of mineral oil microorganism on solid medium effectively, simultaneously, in the Liquid Culture process, above-mentioned two kinds of bacteriostatic agents have fungistatic effect preferably equally, in order to obtain better fungistatic effect, with hydrogen peroxide, Sodium Benzoate and dimethyl fumarate and calcium propionate, Nepal's gold ester has carried out composite, and investigate bacteriostatic agent after composite to the fungistatic effect in the solution that pollutes 200 times of mineral oil dilutions, as table 3, shown in table 4 and the table 5, table 3, control group in table 4 and the table 5 is the mineral oil microorganism of not adding bacteriostatic agent, table 3, table 4 and table 5 are the fungistatic effect of bacteriostatic agent in solid medium of different proportionings:
Table 3
Table 4
Table 5
By comparison sheet 3, table 4 and table 5 find that hydrogen peroxide has extremely strong inhibitory action to the mineral oil microorganism on solid medium, Sodium Benzoate, Nepal's gold ester and the independent fungistatic effect of dimethyl fumarate are lower than hydrogen peroxide, but can reach the fungistatic effect of hydrogen peroxide fully by composite bacteriostatic agent, be that composite bacteriostatic agent has the fungistatic effect consistent with hydrogen peroxide equally, table 3 can effectively suppress the breeding of microorganism to the composite bacteriostatic agent of each prescription shown in the table 5, table 3 to the mistake in the table 5 is a hydrogen peroxide, benzene is Sodium Benzoate, richness is a dimethyl fumarate, and third is calcium propionate.
By in 97.2% emulsifying agent, adding Sodium Benzoate 0.3%, Nepal's gold ester 1.5%, dimethyl fumarate 0.7%, calcium propionate 0.3%, and the emulsifying agent that has added above-mentioned bacteriostatic agent detected with the spinning crude oil that white oil is mixed with, the result is all qualified, and data are as follows:
Viscosity (mm2/s, 37.8 ℃) 65.27
Moisture (%) 5.62
Relative density (37.8 ℃) 0.9058
Low cloud point (℃) 4.4
High cloud point (℃) 63.6
5～15% stability of emulsion are qualified
The bacteriostatic agent that kills that like this Sodium Benzoate, calcium propionate and dimethyl fumarate is re-dubbed is formulated in the emulsifying agent, make this emulsifying agent keep the homeostatic while, be mixed with when not reducing the emulsification dispersion effect after the emulsion, be implemented in the effect that suppresses growth of microorganism in the emulsion.
