Abstract
This invention relates to a novel use of cationic preservatives and preparations according to this novel use. A cationic preservative derived from lauric acid and arginine, in particular, the ethyl ester of the lauramide of the arginine monohydrochloride, hereafter named LAE, can be used for the protection against the growth of microorganisms. The chemical structure of LAE is described in formula (I). LAE and related compounds are particularly suitable to be used in the preservation of all perishable food products. It is preferred to dissolve the compound directly before use in one of the following preferred solvents of food grade: water, ethanol, propylene glycol, isopropyl alcohol, other glycols, mixtures of glycols and mixtures of glycols and water. If the treatment shall be performed at a specific pH value the use of a corresponding buffer solution may be recommendable. The composition optionally comprises auxiliary components and excipients. Such auxiliary components and excipients can be thickening agents (e.g. xanthan gum, guar gum, modified starches), anti-foam agents (e.g. dimethylpolysiloxane, silicon dioxide), products to obtain the optimal pH value (e.g. phosphates, tartrates, citrates, lactates), colouring agents (e.g. curcumin, tartrazine, erythrosine), and aroma products. It is preferred, that the preservative composition comprises LAE in an amount of from 0,0001 % to 1% by weight relative to the whole weight of the preservative composition. It is particularly preferred to use the inventive composition for the preservation of meat products, like for instance meat, poultry products, fish, crustaceans, vegetables, greens, emulsions, sauces, confectionery, bakery, pre-cooked meals, ready-to-serve meals, dairy products, egg-based products, jams, jellies, beverages, juices, wines and beers.
Description
USE OF CATIONIC PRESERVATIVE IN FOOD PRODUCTS
This application is a divisional application of Canadian application serial number
This application is a divisional application of Canadian application serial number
2,464,388 with a filing date of October 25, 2001.
DESCRIPTION
This invention relates to a novel use of cationic preservatives and preparations according to this novel use.
Despite the food industry must avoid the use of preservative products by means of good manufacture practices as it is described in the national and international regulations, it is often necessary to warrant the needed storage capability of the produced food-stuff but never to hide defective effects of a manipulation or manufacture technique.
A cationic preservative derived from lauric acid and arginine, in particular, the ethyl ester of the lauramide of the arginine monohydrochloride, hereafter named LAE, could be used for the protection against the growth of the microorganisms. The chemical structure is described in the following formula:
) H Cl N
NH (CH2ho-CH3 isal2 The preparation of this product has been described in Spanish patent application ES-A-512643.
Biological studies carried out at different research centres under supervision of the present applicant showed LAE to act mainly over the external and cytoplasmatic membrane of the microorganisms and, also, into the cytoplasmatic media, preventing their proliferation. Its action depends on the kind of microorganism and on the exposure time.
Besides, its metabolism in rats has been studied showing a fast absortion and metabolisation into naturally-occurring amino acids and the fatty acid lauric acid, which are eventually excreted as carbon dioxide and urea. Toxicological studies have demonstrated, that LAE is completely harmless to animals and humans.
Therefore, LAE and related compounds are particularly suitable to be used in the preservation of all perishable food products.
This compound is remarkable for its inhibitory action over the proliferation of different microorganisms, such as bacteria, fungi and yeasts. The minimum inhibitory concentrations of LAE are shown in the following table 1.
