  • Patent number: 10370544
    Abstract: A high quality paint comprises water, latex polymer, pigment, and biocidal agent. The coating provided by the high quality paint may be capable of killing gram positive bacteria, gram negative bacteria at a rate of greater than 3 logs within 2 hours of application of bacteria to a painted surface. The coating provided by the high quality of paint may be capable of continuing to kill gram positive bacteria, gram negative bacteria at a rate of greater than 1 log within 2 hours even after repeated contamination of the surface. The coating provided by the high quality paint may be capable of delivering residual killing of gram positive bacteria, gram negative bacteria for up to 48 months. The coating provided by the high quality paint may also be capable of inactivating viruses.

  • Patent number: 4183966
    Abstract: A method of manufacturing a high protein snack food including the steps of inoculating whey, such as derived from cheese making, with yeast, incubating the mixture with aeration until substantially all the whey lactose is utilized by the yeast, heating the culture to precipitate the whey protein, separating the whey protein and yeast cells to provide a paste-like material, mixing the whey protein and yeast cell paste with a filler composed of potato flakes or corn starch or a mixture of the two, plus either baking powder or baking soda (to reduce acidity), plus salt, and egg whites, into a dough, extruding the dough to provide snack-like pieces, frying the pieces in a deep fat fryer, and then cooking the fried pieces in a microwave oven.
