Abstract
The invention provides salts formed from fatty acyl amino acid esters and fatty acyl amino acids and a forming method of the salts that have inhibitory or killing effect for microorganisms. These derivatives also have the properties such as high performance, mildness, and broad-spectrum baceriostasis, and are widely applicable to the products, such as foods, drinks, feeds, home care products, and personal care products. The salts formed from fatty acyl amino acid esters and fatty acyl amino acids according to the invention are liquids that are convenient to add and use, and the salts have good inhibitory effect for common microorganisms, may replace traditional preservatives, and have the advantages of high safety, low irritation, reduced allergy and toxicity risk, low degrading difficulty, good environmental friendliness and the like.
Description
Technical field
The present invention relates to a kind of amino acid derivativges, preparation method, and the derivative is used as microbial inhibitor, in food
Application in product, feed, household care and personal care articles.
Background technology
Preservative is used in food, feed, cosmetics and furniture nursing product, and Main Function is the growth for suppressing microorganism
And breeding, to extend the holding time of product, suppress product putrid and deteriorated.With developing rapidly for the industries such as cosmetics, food,
Safe and efficient protective system is selected, is the problem that current policies and regulations, consumer and research worker pay special attention to.
Many traditional preservatives are all proven to have certain negative effect, and such as DMDMH meeting release formaldehydes, Kathon CG series contains
Chlorine has stimulation to some skin quality, and Bronopol may generate Carcinogenic Nitrosamines, and IPBC may cause to take in iodine, trichlorine
Newly there is negative effect to environment.And parabens, its phenyl ring may accumulate or in specific test system in adipose tissue
The ability of certain simulation female sex hormone estrogen is shown in system.
Regulation is also increasingly stricter for the operating specification of preservative, different plug azoles Lin ketones, Form aldehyde release body, oxybenzene esters
The use of preservative is restricted increasingly.Increasingly stricter cosmetics regulation, the raising of the awareness of safety of consumer and right
The factors such as mistaken ideas, the safety that preservative understands, this series of change promotes the use total amount of traditional preservatives substantially to glide, urgently
Treat new preservative exploitation and application.
Lauroyl arginine ethyl ester hydrochloride is a class security, the extraordinary preservative of effect, be applied to the product of suffering from indigestion,
The anti-corrosion of cosmetics;Used by the food and agricultural organization/combination food additive Committee of Experts of World Health Organization (JECFA) approval;In addition,
Lauroyl arginine ethyl ester hydrochloride also is compliant with the correlation of the countries and regions such as European Union, Australia, Canada and New Zealand
Regulation.
Lauroyl arginine ethyl ester hydrochloride is a kind of white powder, is unfavorable for being added in formula, and fusing point is in 50-58
DEG C, when adding in formula, after needing to dissolve by solid heating and melting or using solvent in advance, in being then added to formula system, make
Its addition is bothered very much, even if in addition, from solvent dissolving, its solubility is also very limited, as only maximum molten in its glycerine
Solution only 20% or so.
The present invention provides a kind of arginine ethyl ester derivative, and such product fusing point is low, and normal temperature is the liquid of clear, can
To be easily dissolved in the common solvents such as glycerine, solubility is up to 70%, can very easily be used for food, medicine and
Cosmetics.
The content of the invention
It is an object of the invention to provide the salt that a kind of fatty acylamino-acid ester and fatty amic acid are formed, such derives
Thing is liquid form, has to microorganism and preferably suppresses or killing effect, can facilitate be widely used in food, beverage,
In the products such as medicine, household care and personal nursing.
The salt that fatty amic acid provided by the present invention and fatty acylamino-acid ester are formed, has to common microorganism
There is good inhibiting effect, traditional preservative can be substituted.
The compound of the present invention has natural origin, high security, low irritant, reduces allergy and risk of toxicity, and
With degradable, advantages of environment protection.
The technical scheme that the present invention is provided:A kind of method for utilizing fatty acylamino-acid ester and fatty amic acid into salt,
By fatty acylamino-acid ester with fatty amic acid into after salt, fungistatic effect is significantly increased.
The salt that fatty acylamino-acid ester of the present invention and fatty amic acid are formed, microorganism is had suppress or
The method of the salt of killing action, concretely comprises the following steps:
