  • Patent number: 11576407
    Abstract: The present invention relates to preservation of meat products. In particular new additives are provided for effective inhibition or prevention of bacterial outgrowth in meat products. The present inventors found that a combination of carvacrol and a cationic surfactant was effective in the inhibition or prevention of bacterial outgrowth in meat products. The combinations, more in particular, proved to be effective at levels that do not result in significant effects on the flavor and/or taste of the products. The present inventors furthermore found that treatment of meat products with the combinations of this invention had a favorable effect on the visual appearance (color) of the meat products. The present invention provides preservative compositions, the use of thereof as well as the meat products containing them.

  • Publication number: 20170006907
    Abstract: The combination of EGCG and a derivative of a basic amino acid has been found to be an effective anti-yeast agent in acidic food. The present invention relates to a method for controlling or preventing the growth of yeast in acidic food (i.e. with a pH between 2 and 6) comprising adding to said food a) epigallocatechin gallate (EGCG) and b) a derivative of a basic amino acid, and/or a salt thereof, as an anti-yeast agent. The present invention further relates to a composition for addition to food and to an acidic food comprising said composition.

  • Publication number: 20140302217
    Abstract: The present invention relates to a preservative system capable of protecting against spoilage by bacteria, yeasts and moulds in carbonated and non-carbonated beverages. In accordance with the invention this objective is realized with a preservative system comprising a combination of propionate with vanillin and/or cinnamate. Vanillin and propionate are both known for their anti mould action. However the dosages that are needed of the separate ingredients are too high for most applications. The present inventors found that potassium cinnamate at low concentrations has a positive effect on the inhibition of moulds in combination with vanillin and propionate. Moreover, the present invention, using a combination of vanillin, propionate and cinnamate accomplishes complete inactivation of all moulds at manageable sensory levels.

  • Patent number: 8802403
    Abstract: Disclosed herein is a genetic modification of moderately thermophilic Bacillus species that are facultative anaerobic and homolactic. The method includes introducing DNA cloned in a thermosensitive plasmid system containing a pSH71 replicon or a homologue thereof into cells of a moderately thermophilic Bacillus species that is facultative anaerobic and homolactic; culturing the cells on a selective medium at a permissive temperature to select transformed cells; culturing the transformed cells on a selective medium at a non-permissive temperature to select transformed cells capable of growing on the selective medium at the non-permissive temperature. The method can modify the Bacilli for R-lactic acid production, production of other organic acids than lactic acid, alcohol, enzymes, amino acids, and vitamins. The Bacillus species may be modified by replacing the S-lactate dehydrogenase gene by a DNA construct including a DNA sequence encoding R-lactate dehydrogenase.
