Abstract:
Method for extending the shelf-life of a foodstuff Methods of extending the shelf-life of a foodstuff and/or for preventing or reducing microbial (e.g. bacterial) growth on said foodstuff are provided. The methods comprise coating the foodstuff with a composition comprising at least one acidic biopolymer, preferably an edible acidic biopolymer, e.g. a polysaccharide, and optionally storing said coated foodstuff. Also provided are compositions for use in said methods, processes for coating foods with said compositions and uses of said compositions.
Abstract:
The present invention relates to a method of improving the safety, the quality and the durability of foodstuffs and raw materials which are used in the production of foodstuffs, and to a foodstuff or a foodstuff raw material. A foodstuff or a foodstuff raw material is treated with pure nitrogen gas in order to prevent the growth of microbes in the foodstuff or the foodstuff raw material. The nitrogen gas method according to the present invention makes it possible to eliminate efficiently the bacteria which produce large quantities of phospholipase from the foodstuff or the foodstuff raw material. The nitrogen gas method is especially suitable for the treatment of milk products, particularly raw milk.
Abstract:
A dairy product is prepared by adding a non-lactose fermenting and non-galactose fermenting yeast or a non-fermentative yeast to a dairy starting material or dairy product in an amount sufficient to extend the shelf life of the resulting mixture or products prepared from it and if required further processing the mixture to obtain a further dairy product, wherein the yeast is weakly proteolytic or non-proteolytic and also weakly lipolytic or non-lipolytic. The invention also provides a method for preparing a milk product having a pH of less than 5.5 and a moisture content of at least 30% (w/v), comprising adding one or more types of lactic acid bacteria or probiotics to a dairy starting material wherein a stabilising non-lactose fermenting and non-galactose fermenting live yeast or a stabilising dead yeast or yeast extract is added before, during or after the bacteria or probiotic adding step to extend the survival of the lactic acid bacteria or probiotic at counts of ≥ 10 5 per g or ml, wherein the yeast or extract is weakly proteolytic or non-proteolytic and also weakly lipolytic or non-lipolytic.
Abstract:
The invention relates to a method for impregnating, incorporating or surface-treating substances/articles that can be microbially decomposed, contaminated and/or infested with parasites and/or that are perishable. The inventive method comprises the following steps: applying a special antimicrobial/antiparasite composition on the substances/articles or incorporating the antimicrobial/antiparasite composition in the substances. The invention further relates to said special antimicrobial/antiparasite compositions, to their use for impregnating and/or surface-treating substances that can be microbially decomposed, contaminated and/or that are perishable or substances that are infested with parasites and to the use thereof in substances and products that have to be self-contaminating.
Abstract:
The present invention relates to a supporting product which is added during fermenting of cheese and yoghurt and which provides extending the lifetime of cheese or yoghurt and which provides high nutrient values to cheese or yoghurt.
Abstract:
The invention relates to a method for making a cheese product comprising: - subjecting ripened packed cheese to an anti-microbial treatment; - thereafter removing the packing material from the treated cheese; and - thereafter extruding the treated cheese to form a shaped cheese product or shredding the treated cheese to form a shredded cheese product. The cheese product accordingly obtained is also claimed.
Abstract:
The present invention relates to a process for producing cheese. The method is particularly suitable for shredded cheese or block cheeses. More in particular, the process comprises the step of adding an antifungal to the cheese. Furthermore, the present invention relates to a device for producing cheese.
Abstract:
A highly acidic metalated organic acid composition and its preparation. The acidic composition can be prepared by mixing a monovalent or polyvalent cation and an organic acid in the presence of a strong oxyacid, wherein the resultant acidic composition is less corrosive to a ferrous metal than a solution of a mineral acid having the same acidic pH value as that of the acidic composition, and where in the acid composition is more biocidal than a mixture of the organic acid and metal salt of the organic acid which the mixture has the same acid normality value as that of the acidic composition. The acidic composition can be prepared by mixing at least one regenerating acid, at least one metal base, and at least one organic acid, wherein the amount of the regenerating acid is in excess of the equivalent amount of the metal base.
Abstract:
The invention relates to the use of nonanoic acid as an antimicrobial, in particular antifungal, agent or additive, in particular in or for foods, such as dairy products or fruit juices. A particular aspect of the invention comprises the use of nonanoic acid i a cheese coating. The invention also relates to a cheese coating in which nonanoic acid has been incorporated as antifungal agent; a cheese that has been provided with such a coating; and a nonanoic acid-containing composition for applying such a coating. The nonanoic acid is used in particular on or close to the surface of the food, or uniformly distributed through the food, in an amount of 10 - 10,000 ppm, in particular 100 - 1,000 ppm. The nonanoic acid can furthermore be used as an antimicrobial agent for treating substrates or surfaces, in particular substrates or surfaces that come into contact with foods; for protecting foods, cut flowers and bulbs during transport and/or during storage; in disinfectants and cleaning agents; to protect or treat wood; in cosmetics or skin care products; and in pharmaceutical compositions to prevent and treat fungal infections and yeast infections , such as Candida .
