PROBLEM TO BE SOLVED: To provide a protein composition having high heat resistance in a wide pH range in high temperature heat treatment of equal to or more than 90°C and retort sterilization of equal to or more than 120°C, and obtained by mixing a raw material normally used for various food and drink, feed and medicine without deactivating a milk basic protein fraction.SOLUTION: A protein composition which contains a milk basic protein fraction, and at least one kind of stabilizer selected among soybean polysaccharide, xanthan gum, pectin, gum arabic, ghatti gum, carrageenan, locust bean gum, sodium caseinate, lecithin and carboxymethyl cellulose remarkably improves heat resistance of the milk basic protein fraction. The protein composition, and food and drink, feed and medicine comprising the composition can be heat-treated at equal to or more than 90°C without deactivating the milk basic protein fraction. |
