Abstract: Disclosed herein are methods of forming a fiber mat, involving forming an aqueous solution of at least one protein, at least one polysaccharide, and optionally a plasticizer, and electrospinning the aqueous solution onto a collector to form a mat.

Abstract: Improved casein-based films are produced by adjusting the pH of a film-production suspension. The film-production suspension may contain a casein source, a plasticizer, and optionally a strengthening additive. The adjustment of the pH may be accomplished by the addition of an alkaline additive, such as a base, to achieve a desired pH value. The improved casein-based films have improved physical properties as compared to those produced without a pH-adjusted film-production suspension at least in part due to the chemical and structural changes imparted by the change in pH.

Abstract: Processes for concentrating protein, especially digestible protein from plants, and particularly the concentration of protein from non-animal sources without contaminating the protein with ingredients used in a purification process.

Abstract: An edible, water-resistant composition that can be formed into shaped articles including film comprises a water-resistant solid composition of casein. The casein composition may be directly precipitated from a solution under high pressure treatment with carbon dioxide. The composition does not have to be crosslinked, but takes advantage of the natural water-insolubility of the protein backbone of the casein. The casein composition may be combined with edible or inert flexibilizers to improve film properties, and the film may be used to protect food products or food compositions, yet provide moisture protection. The film of casein material may exhibit water-insolubility in deionized water at 20° C. of less than 25% by weight after two hours of immersion of the film in the deionized water, with or without mild agitation.

Abstract: In the manufacture of hard cheese, cheese milk is treated with high pressure CO2 to accelerate the precipitation of casein and thereby promote the rapid formation of curd. Curd can be produced by this process in a period of a few minutes without adverse affects on the rennet or starter culture. The high pressure CO2 treatment of cheese milk can substantially increase the daily curd yields and plant throughput, thereby significantly reducing processing costs.

Abstract: A process for the fractionation of proteins from an aqueous solution of whey is described. The process includes mixing the solution with carbon dioxide under pressure, heating the mixture to increase the pressure, releasing the pressure and lowering the temperature of the mixture, then separating a supernatant liquor from a precipitate which results from the process.

Abstract: The continuous removal of solid products from a high-pressure system is achieved by operating a high-pressure pump in reverse to gradually reduce pressure at the exit line to atmospheric pressure. This process allows solid products to exit the system while at the same time maintaining high pressure in the reactor.
