Abstract:
The present invention relates to a method for the prevention and/or reduction of the presence, growth and/or activity of gram-negative bacteria comprising application of a composition comprising glycerol-based fatty acid esters and polylysine and/or salts of polylysine, wherein said glycerol-based fatty acid ester is used as antibacterial agent. The present invention further relates to the use of said composition as antibacterial agent in various products and applications ranging from technical products and personal-care products to food and drink products for animals and human consumption.
Abstract:
An antimicrobial composition for food applications includes a chelating agent and a lauric acid derivative. The antimicrobial composition optionally includes one or more carboxylic acid derivatives. The chelating agent, the lauric acid derivative, and if present, one or more carboxylic acid derivatives are collectively present in an amount that is less that a taste threshold.
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:
Carboxylic anhydrides are outstandingly suitable as an additive to industrial materials, cosmetics, pharmaceuticals and foods, especially drinks, to protect them from infestation and/or destruction by microorganisms.
Abstract:
The present invention disclose the composition of antioxidant of bamboo leaves (AOB) and its use. The purpose of present invention is to provide a new food additive which is natural, nutritional, and muti-functional, and which is of rich resources, safety, good effect, low cost. AOB is yellow or brown powders or particles obtained from bamboo leaves, wherein the main antioxidative components include flavones, lactones, phenolic acids. AOB can either inhibit lipid autoxidation chain reaction, or chelate transitional metal ions, and can be used as primary and second antioxidant. AOB can eliminate nitrite and inhibit the synthesis of N-nitrosamine, and has anti-bacteria, bacteriostatic, deodorizing, aroma-enhancing etc. functions. AOB can be commonly used in oil-containing food, meat product, fishery product, expanded food etc. food systems.
Abstract:
The present invention is concerned with a method for enhancing the flavor shelf life of beverages, including beer and other malt beverages, by incorporating Labiatae herb extracts either to the finshed beverage or into a step in the manufacture of the beverage.
Abstract:
A process for inhibiting enzymatic activity in a substrate in liquid phase, by the application of denaturing means to the substrate up to a temperature set between 0 and 60 ° C, preferably set between 10 and 50 ° C, and in particular at room temperature. As denaturing means either the application to the substrate of gaseous ozone or the application to the substrate of UV waves for a predetermined time are provided. UV waves and gaseous ozone may also be provided as combined denaturing means, at the same time or in different times, generated by a same device. The substrate to which the invention is applied can be: a food matrix, such as vegetable juice or puree, fruit juice or puree; a pure enzyme or a mixture of enzymes in liquid phase, in particular contained in liquid food; enzymes and mixture of reagents used for biochemical synthesis; waste material where inhibiting the enzymatic activity is necessary before 20 disposal. The process does not damage or affect the substrate and do not apply heat, and successfully inhibits the enzymatic reactions caused by enzymes present in the substrate. The advantage of working at a temperature less than 60 ° , and preferably at room temperature, implies less energy absorption since the substrate must not any more be heated and cooled as required by traditional techniques, as well as it does not affect the characteristics, vitamins and fragrances of the treated food substrates.
