FOOD AND DRINK-PRODUCING YEAST IN WHICH IDENTITY OF YEAST IS EASILY DISCRIMINATED, FOOD AND DRINK, AND METHOD FOR DISCRIMINATING IDENTITY OF YEAST USED FOR PRODUCING FOOD AND DRINK

摘要

PROBLEM TO BE SOLVED: To provide a technique for easily discriminating identity of yeast and improve quality and reliability of food and drink produced by using the yeast.SOLUTION: Yeast is brought to be food and drink-producing yeast imparted with identification information in determining identity of the yeast by mutating a gene unnecessary to be expressed in producing food and drink, thus obtaining yeast from the food and drink produced by using the yeast in producing the food and drink by using the food and drink-producing yeast, and determining if the base sequence pattern of a predetermined gene of the yeast coincides or not with the base sequence pattern of a predetermined gene of the food and drink-producing yeast in which the identity of the yeast is easily discriminated, and in the case of coincidence, the food and drink is determined to be the food and drink which has been produced by using the food and drink-producing yeast in which the identity of the yeast is easily discriminated.
