Abstract: This invention pertains to method of using a composition comprising one or more hydrophobically modified polyacrylamides, wherein the polyacrylamides contain acrylamide, one or more anionic monomers, and excludes a cationic monomer, and the method of combination with other compositions for use in combination for consumer and/or industrial applications.

Abstract: A hand-held implement for removing microbiological matter from a surface to which the matter is adhered, and storing the matter for subsequent examination, includes a sonic wave generator for producing sonic waves for breaking up a film of the microbiological matter on the surface, a swab for contact with the surface and collecting the microbiological matter, a suction producing device for drawing the microbiological matter from the swab and into the implement, and a trap in the implement for receiving and retaining the drawn biological matter for subsequent examination thereof.

Abstract: A method of treating solid and semi-solid foods to reduce microorganisms and enzymes in the food including introducing solid or semi-solid food to a pressure vessel, exposing the food in the vessel to supercritical carbon dioxide to reduce the one or more microorganisms or enzymes, exhausting the supercritical carbon dioxide at a rate to maintain organoleptic integrity of the food.
