Antimicrobial compositions comprising sulfur- or selenium-containing, fatty-acylated alpha-hydroxy acid compounds and methods of using said compounds or compositions to inhibit microbial growth.

The present invention relates to an antimicrobial composition having activity against Gram-positive and Gram-negative bacteria. The composition is a) a composition comprising at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; b) a composition comprising at least two bacteriocin selected from the group consisting of pediocin, Nisin and reuterin; c) a composition comprising pediocin and at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; or d) a composition comprising reuterin and at least one organic acid selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid. The present invention also relates to the use of said compositions for sanitizing and/or disinfecting surfaces and method thereof.

A system providing for on-site reclamation and re-use of reclaimed antimicrobial solution includes a dispenser, at least one receptacle, piping, and at least one pump. The dispenser sprays antimicrobial solution toward moving raw food products. Unspent antimicrobial solution that did not contact the moving raw food products and rebound antimicrobial solution that did contact the raw food products combine to form a reclaimed antimicrobial solution. The reclaimed antimicrobial solution is collected in the receptacle and is pumped through the piping to a location for reuse.

The present invention relates to a method for inactivating Cronobacter sakazakii, which belongs to the field of food safety technologies. The present invention provides a method to use tea polyphenols as an active ingredient to inactivate Cronobacter sakazakii. The invention can be used to control and eliminate the contamination of Cronobacter sakazakii in food or food processing, especially the contamination of Cronobacter sakazakii during PIF production. The present invention provides an effective method to clean and sterilize the environment and the equipment, especially to clean the inner wall of the equipment which is hard to clean due to biofilms formed inside.

The present invention relates to an antimicrobial composition having activity against Gram-positive and Gram-negative bacteria. The composition is a) a composition comprising at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; b) a composition comprising at least two bacteriocin selected from the group consisting of pediocin, Nisin and reuterin; c) a composition comprising pediocin and at least two organic acids selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid; or d) a composition comprising reuterin and at least one organic acid selected from the group consisting of lactic acid, acetic acid, benzoic acid and citric acid. The present invention also relates to the use of said compositions for sanitizing and/or disinfecting surfaces and method thereof.

A synergistic system for substantially reducing surface contaminants of a food and inhibiting yeast, mold and bacteria growth in a food, beverage or food grade cosmetic preparation comprising a substantially transparent and odorless solution made from a plurality of substantially organic compounds selected from: citric acid, sodium citrate, vegetable glycerin, sea salt, potassium sorbate, decyl glucoside, calcium ascorbate, grapefruit seed extract, quillaja saponin, calcium carbonate, ascorbic acid, sodium percarbonate and sodium bisulfate, and an applicator for applying the solution to the food substance.

The present invention relates to novel strains of Propionibacterium as well as preparations and compositions, such as fermentation broths, protective cultures, final food or feed product with Propionibacterium alone or in combination with bacteria of the genus Lactobacillus. The present invention further relates to methods for the controlling of growth of a contaminant, such as a bacteria, yeast or mold by using these novel strains of Propionibacterium.

The present invention describes natamycin comprising needle shaped crystals.

The present invention relates to new antimicrobial compositions and their use in the treatment of products such as food products.

The present invention relates to compositions including medium chain peroxycarboxylic acid, methods for making these compositions, and methods for reducing the population of a microorganism. The compositions can include advantageously high levels of the medium chain peroxycarboxylic acid, can be readily made, and/or can exhibit reduced odor.
