Fecha de publicación: 09/01/2025 Fuente: WIPO "tomato" A composition containing yeast protein, a preparation method therefor, and the use of the yeast protein and the composition. The outer layer of the yeast protein is coated with zymosan; the yeast protein is in the shape of a sphere or an ellipsoid; the yeast protein has a protein content of 70% or more and a zymosan content of 5%-30%, calculated as the weight percentage of a dry base. The yeast protein of the present invention has obviously lower digestibility than that of soybean protein isolate and whey protein in the stomach, causes a stronger satiety after being eaten compared with whey protein, has the characteristic of slow digestion, and is a slow-digesting protein. The yeast protein of the present invention also contains 18 amino acids, including eight essential amino acids and two semi-essential amino acids for the human body, and thus is a complete protein due to the full type of amino acids. The yeast protein can be used as the slow-digesting protein in the preparation of a composition which is intended to be enterally administered to mammals so as to regulate the postprandial amino acid level in the blood plasma.
