  • Publication number: 20230263195
    Abstract: The present invention relates to compositions and processes for preparing microbially stable edible products from dough and to processes and compositions for preparing edible dough-based products having improved mold resistance, extended shelf-life and good organoleptic properties. In accordance with the invention combination of an acetate component and a propionate component, in particular combinations of a (buffered) vinegar and a propionate component prepared by fermentation can be applied in bread and other baked dough products to accomplish satisfactory mold inhibitory effects at dosages that do not (negatively) affect the organoleptic properties of the product, such as flavor, taste or aroma. Hence, the present invention provides new preservative systems, the uses thereof for inhibiting mold in baked dough products, and the baked dough products accordingly obtained.

  • Publication number: 20220240528
    Abstract: Methods to prepare a fruit ferment containing propionic acid and/or a salt thereof comprising i) obtaining a liquid fruit preparation, ii) optionally supplementing the liquid fruit preparation with water and/or with additional components to support fermentation, iii) fermenting the optionally supplemented liquid fruit preparation with a propionic acid-producing bacterial strain, iv) optionally further processing the fermentation product, to obtain the fruit ferment. Next to a propionic acid-producing bacterial strain, a lactic acid-producing bacterial strain may be used in the fermentation. And, a fruit ferment obtainable by said method.

  • Patent number: 10040833
    Abstract: The present invention relates to fermentation processes. The objective of the invention was to provide methods for producing nisin containing ferments and formulating such ferments into preservatives. It was in particular an object of the present invention to provide improved processes for producing nisin containing ferments by simple and efficient (batch) culturing and allowing for simple down-stream processing either into a liquid, semi-liquid or a dry powder product, having sufficient nisin content and stability, good handling properties and satisfactory organoleptic properties. Such processes are provided, as well as the products that can be obtained with it and their use.

  • Publication number: 20150140186
    Abstract: The protection of low-acid, high moisture and/or high water activity processed food products against outgrowth of Clostridium botulinum. It was surprisingly found that combinations of propionic acid and/or a salt thereof with nisin are very effective in preventing Clostridium botulinum outgrowth. In certain embodiments, cinnamic acid and/or a salt thereof can be added to these combinations to give particularly good results. These combinations provide a preservative system that is particularly effective against Clostridium botulinum outgrowth. The use of these preservative systems in food products that are conductive to Clostrisium botulinum outgrowth. The food products including these preservative systems and the methods of producing them.
