    摘要: The disclosure pertains to a method for preparing a protein-based film wherein modified protein containing free sulfhydryl groups is added to a solution containing protein and the free sulfhydryl groups cause an interchange reaction wherein disulfide bonds will be formed between proteins to form a film structure to coat a product. The disclosure also pertains to a protein-based film.

    摘要: A method for modification and isolation of a protein is provided. The method includes the steps of providing a protein selected from the group consisting of whey and soy proteins; providing a reagent that forms sulfite ions; mixing the protein with the reagent under a condition to sulfonate the protein without using an oxidizing agent and to obtain a mixture containing a sulfonated protein; precipitating the sulfonated protein out of the mixture at an acid pH to form a precipitated sulfonated protein and a soluble sulfonated protein; and recovering the precipitated sulfonated protein or soluble sulfonated protein.

    摘要: The invention relates to a method for isolating proteins from whey, wherein the whey or a concentrate thereof, a reagent which forms sulfite ions, and an oxidative compound are contacted in order to sulfitolyze and oxidize the whey protein, the sulfitolyzed and oxidized whey protein is precipitated out from the whey or concentrate thereof at an acid pH, and the precipitated sulfitolyzed and oxidized whey protein is recovered from the product mixture, and an after-treatment is possibly performed on it. When a food-grade oxidative compound is used as the oxidant and a temperature within the range 25.degree.-55.degree. C. is used, the oxidative compound can be caused to react directly with the sulfitolyzed whey protein, and thus the disadvantages associated with the use of a catalyst are eliminated.
