Abstract:
The present invention relates to antimicrobial compositions which can be used in food preservation. The compositions according to the invention are based on the lactoperoxidase system (LPS), and comprise very low concentrations of lactoperoxidase, glucose oxidase, thiocyanate, and optionally glucose. The invention further relates to the use of such compositions, in particular in synergistic combination with heat treatment, in food preservation, methods for food preservation, and food products comprising these compositions.
Abstract:
A process for producing powdery egg characterized by comprising adding an aqueous solution of an edible acid to the whole egg (including the egg shell) at a ratio of at least 150 ml of the solution per 100 g of the whole egg, thus immersing the egg in the solution at a temperature of about 0 to 50 DEG C, optionally filtering the acid-treated egg solution thus obtained, and then spray drying the same at a blowing temperature of 180 DEG C or above and at an exhaust temperature of 120 DEG C or above; or adding an aqueous solution of an edible acid and a hydrolase to the whole egg (including the egg shell), thus decomposing the egg at a temperature of 0 to 50 DEG C, optionally sterilizing by heating and/or filtering the thus obtained decomposed liquid product, and then powdering the same by drying.
Abstract:
The present invention relates to liquid nisin compositions having a high anti-microbial activity. The invention further relates to a method for preparing the liquid nisin compositions as well as their use as a preservative in food products.
Abstract:
Food products can include dried microorganisms as a biocontrol agent. The dried cultures resist inactivation during pasteurization of the food product. The microorganisms are selected to be nontoxic and to inhibit growth of pathogenic microorganisms. For example, the biocontrol microorganisms can produce acid to lower the pH of the product thereby inhibiting the growth of pathogens.
Abstract:
Disclosed herein are bio-based additives such as enzymes and peptides for reducing microbial contamination of food packaging coatings and food that contacts the food packaging coating. Methods of preparing and using a food packaging coating having such bio-based preservatives is also disclosed. Articles of manufacture and devices such as food packaging comprising such a food packaging coating are described.
Abstract:
The present invention relates to microcapsules, and more particularly to microcapsules where an aqueous bead or beads comprising the active ingredient is encapsulated in or by a hydrophobic shell matrix. The present invention relates also to novel methods for preparing the microcapsules according to the invention, as well as to the use of the microcapsules of the present invention. A microcapsule of the present invention comprises a solidified hydrophobic shell matrix, an encapsulated aqueous bead or beads which is/are encapsulated in or by the solidified hydrophobic shell matrix, and an active ingredient or active ingredients dissolved or incorporated in the encapsulated aqueous bead or beads.
Abstract:
The subject invention provides compositions and methods for preserving food products. Specifically, the subject compositions and methods can be used to prolong the consumable life of food products, as well as to reduce and/or prevent spoilage and/or contamination by microbial agents. Preferably, the compositions comprise a blend of one or more glycolipids and one or more lipopeptides. Even more preferably, the compositions comprise sophorolipids and surfactin, lichenysin or another lipopeptide biosurfactant.

Abstract:
The present invention discloses a method and composition for the treatment of bacterial contamination of food by the use of a phage associated lysing enzyme, preferably blended with an appropriate carrier. The method for treating food stuffs comprises treating the food stuffs with an anti-infection agent comprising an effective amount of at least one lytic enzyme produced by a bacteria infected with a bacteriophage specific for the bacteria.. Additionally, chimeric lytic enzymes shuffled lytic enzymes, and holin proteins, either alone or in combination, may be used to treat or prevent bacterial contamination of foodstuffs. The lytic enzyme can be used for the treatment or prevention of various strains of Staphylococcus, Streptococcus, Listeria, Salmonella, E. coli, Campylobacter, Pseudomonas, Brucella, other bacteria, and an,Y combination thereof. Feed for livestock, poultry and beef in slaughterhouses, canned and bottled goods, salad bars, and eggs are just some of the food items that can be treated with at least one lytic enzyme to reduce the risk of food contamination by bacteria.
