Abstract

The present invention addresses the problem of providing: a peptide; a GLP-1 secretion promoter; a pharmaceutical composition; a food composition; a method for suppressing appetite; a method for suppressing an increase in blood glucose level; a method for improving obesity; and a method for producing a novel food material.　As an invention for solving the problem, there are provided: a peptide which comprises the amino acid sequence GSIGAASMEF (SEQ ID NO: 1) and in which the amino terminal is acetylated; a GLP-1 secretion promoter, a pharmaceutical composition, a food composition, a method for suppressing appetite, a method for suppressing an increase in blood glucose level, and a method for improving obesity, each of which uses the peptide; and a method for producing a food material, the method including a step for heating a granular or powdery material containing an egg white-derived protein in the presence of an edible oil having a temperature of 120°C or higher.

Claims

1. A peptide consisting of the amino acid sequence GSIGAASMEF (SEQ ID NO: 1), with the amino terminus being acetylated.

2. The peptide according to claim 1, wherein the carboxyl terminus is further amidated.

3. A GLP-1 secretion promoter comprising the peptide described in claim 1 or 2.

4. A pharmaceutical composition comprising the peptide described in claim 1 or 2.

5. The pharmaceutical composition according to claim 4 for the purpose of suppressing appetite, suppressing the rise in blood glucose levels, and / or improving obesity.

6. A food composition comprising the peptide described in claim 1 or 2.

7. The food composition according to claim 6, wherein the peptide is added.

8. The food composition according to claim 6 for the purpose of suppressing appetite, suppressing the rise in blood glucose levels, and / or improving obesity.

9. A method for suppressing appetite, comprising the step of administering the peptide described in claim 1 or 2.

10. A method for suppressing an increase in blood glucose levels, comprising the step of administering the peptide described in claim 1 or 2.

11. A method for improving obesity, comprising the step of administering the peptide described in claim 1 or 2.

12. A method for producing a food material, comprising the step of heating a powdered or granular material containing egg white-derived protein in the presence of edible oil at 120°C or higher.

13. The method for producing a food material according to claim 12, wherein the powder material containing egg white-derived protein is whole egg powder, egg white powder, or purified ovalbumin powder.

14. A method for obtaining a food material for use in suppressing appetite, suppressing blood sugar level rise, and / or improving obesity, according to claim 12 or 13.

15. A method for producing a food material in which the content of a peptide consisting of the amino acid sequence GSIGAASMEF (Sequence ID 1) and in which the amino terminus is acetylated is increased.
