Described is an initial liquid composition with at least antimicrobial, antibacterial, and/or anti-viral properties comprising chelated metal oxide particles suspended in a polyol, such that metal oxide particles are homogeneously dispersed in a primarily liquid based polyol carrier so that chelated metal oxide particles form a stable complex suspension that is optionally an alkaline based aqueous silver oxide dispersion. The liquid composition can be subsequently added to any polymer or polymer compound/system where the polymer degrades or melts at a temperature lower than the polyol carrier degradation or boiling temperature. The metal oxide complex may also impart beneficial semi-conductive or conductive as well as permeability and flammability property changes to the polymer (host) system.

The disclosure relates to preparation, processing, and packaging of fresh foods, particularly proteins. In various implementations, the methods include steps for ozone exposure, reduction of surface moisture, introduction of a modified atmosphere, and high pressure pasteurization. Prior to packaging the protein may be exposed to ozone and undergo dehydration to reduce the amount of moisture on the surface of the protein. The protein may then be packaged in a modified atmosphere, lacking oxygen, and then undergo high-pressure pasteurization.

A composition in powder form comprising alginic acid or sodium alginate, -pectin and chitosan, wherein the % by weight of the polysaccharides is at least 20% with respect to the total weight of the powder, the process for preparing the powder and its use in the treatment of cutaneous wounds and in the sector of food preservation are described.

A method of washing a food product with a short-term, intense treatment solution. One example method generally includes: applying, using a short-term wash device, a short-term wash treatment solution to the food product; and applying, using a wash device coupled to the short-term wash device, a wash treatment to the food product such that the wash treatment rinses the short-term wash treatment solution from the food product, wherein: the short-term wash treatment solution is applied to the food product for a shorter duration than the wash treatment is applied to the food product; the short-term wash treatment solution is chemically different from the wash treatment; and the short-term wash treatment solution comprises an acidulant and a polyol.

The present invention discloses an antifreeze solution for food preservation, which comprises edible alcohol, propylene glycol, glycerin, calcium chloride, sodium chloride, amino acid, Antarctic krill protein hydrolysate with an average molecular weight of 50-100 KDa, surfactant and water, wherein the surfactant is one or more of phospholipid, Tween-20, Tween-60, and Tween-80; each component is food grade, and the mass percentage is expressed as follows: alcohol 15-30%, propylene glycol 10-30%, glycerol 2-15%, calcium chloride 1-10%, sodium chloride 3-10%, amino acid 0.1-0.15%, Antarctic krill protein hydrolysate 0.01-0.3%, surfactant 0.005-0.5%, and the balance is water. The antifreeze solution provided by the present invention can lower the freezing point, improve the heat transfer efficiency, inhibit the crystallization of antifreeze solution during the low temperature stirring process and improve the stability of the antifreeze solution.

The disclosure includes novel food coatings and methods of preserving foods and of protecting against damage and/or spoilage to improve appearance, shelf life, and marketability of the foods. The food coatings involve a chitosan solution including chitosan, an organic acid, and a sulfite salt. The food coatings are edible and may create a film on food that protects the food from discoloration, mold growth, and spoilage. The chitosan solution may be applied by spraying, immersion, wiping, fogging, etc. The chitosan solution is show to extend shelf-life of at least catfish, beef steak, hamburger, fruit, vegetables, and berries.

An embodiment of the present invention makes it possible to sterilize a marine animal with use of sea water and atmospheric air, to the extent that the marine animal can be eaten as an unheated food product. A sterilization method in accordance with an embodiment of the present invention is a method for sterilizing a marine animal as an unheated food product, the method comprising the steps of: producing oxygen-enriched water by mixing electrolyzed atmospheric air into sea water; producing sterilizing water by electrolyzing the oxygen-enriched water; and bringing the marine animal into contact with the sterilizing water, the sterilizing water containing HOCl, OH.sup.− and O.sup.−.
