Abstract:
Described herein are food preservation compositions. The compositions are composed of an absorbent material and an antimicrobial agent. The antimicrobial agent can be a volatile, nonvolatile, or a combination thereof. The compositions are effective in reducing or preventing microbial growth in food storage articles.
Abstract:
The invention relates to salts of the carboxylic function in rosmarinic acid, selected from a sodium salt isolated from tissue of plants of the Labiatae family, rosmarinic acid salts other than the sodium salt, or admixtures of other salts with the sodium salt, the other salts or admixtures being those obtained by cation-exchange with the isolated sodium salt; to an antioxidant material isolated by extraction from tissue of plants of the Labiatae family, which is completely water-soluble and has a long shelf-life at ambient temperatures; to an aqueous solution which comprises the antioxidant material; and to a process for preparing completely water-soluble antioxidant material comprising the sodium salt of rosmarinic acid, and its aqueous solutions.
Abstract:
Antioxidative protection is conferred on a substance liable to oxidative deterioration, by admixing it with at least one compound selected from sub-groups ( alpha ), ( beta ) and ( gamma ), namely: ( alpha ) rosmarinic acid; ( beta ) salts of the carboxylic acid function in rosmarinic acid; ( gamma ) esters and amides of the carboxylic acid function in rosmarinic acid; subject to certain provisos.
Abstract:
A process for the extraction and isolation of concentrated carnosic acid from plant matter of the Labiatae family including contacting the plant matter with a water-miscible solvent to form a plant extract and adjusting the pH of the plant extract to a level between 7 and 10 while adding water in an amount sufficient to cause precipitation of impurities while retaining the carnosic acid salt in solution. The impurities are separated and the remaining aqueous solution is acidified to precipitate a highly purified carnosic acid product which is essentially odorless, flavorless and colorless.
Abstract:
There are provided methods of treating edible matter comprising applying a composition comprising performic acid to the edible matter or a substrate therefor. Other embodiments are also disclosed.
Abstract:
The present invention has as an objective to provide a pureed composition comprising cinnamon, which is of excellent sensory quality, and which is microbiologically safe and stable upon storage, and which rapidly delivers atrtactive flavours. This objective is met by a pureed water-continuous cinnamon composition, comprising cinnamon, vegetable oil, insoluble fibres and which is acidified. Also provided is a process for preparing said composition.
Abstract:
The present invention discloses antimicrobial compositions of modified coconut oil and palm kernel oil derived from catalytic activity of 1,3 positional specific lipases. Said modified oil compositions comprises of free fatty acids (>9.4%), monoglycerides (>1.3%), diglycerides (>22.8%) and triglycerides (>25%) which inhibits the growth of gram positive bacteria i.e. Staphylococcus aurous aureus, Listeria monocytogenes, Sterptococcus pyogene , gram negative bacteria i.e. Vibrio cholerae, Escherichia coli and yeast i.e. Candida albicans .
Abstract:
Preservative systems on the basis of cationic surfactants are known i n the art, a typical example of such cationic surfactants is the ethyl ester of the lauramide of arginine monohydrochloride ( LAE ) (2). Besides the chloride form the corresponding bromide and sulphate salts are known. It was found that other salts of the cationic surfactants display excellent properties, such as the salts oflactic acid, glutamic acid and acetic acid. It was further found that the combination of the cationic surfactants with at least one salt of an organic or inorganic acid displayed an excellent preservative action. A further preservative system with favourable properties was the combination of the cationic surfactants with at least one ester compound, amide or enzyme inhibitor. Also the combination of the cationic surfactant with a further cationic molecule such as ethyl arginate, glucosamine or chitosan led to an effective preservative system. A further effective preservative system turned out to be the cationic surfactant in encapsulated form.
Abstract:
The invention relates to an antimicrobial composition, use of said composition for converting and/or stabilising microbial perishable products, use of said composition as a process assistant, as well as to microbial perishable products which contain said antimicrobial composition.
