Abstract
A yeast-derived bioactive peptide having activities as an anti-stress agent, an anti-fatigue agent, premenstrual syndrome(PMS) and menstrual pain relaxants, and a brain-neurotrophic factor, and a method for preparing the bioactive peptide are provided. The preparation method involves incubating a strain of yeast, which is a natural source reconigzed as safe, until a maximum growth phase. The generation and release of anti-stress substances beneficial to the human body from the yeast are induced by properly applying a physical or chemical stress, such as high-temperature heating, ultrasonic waves, vibration, pH variations, etc. Next the yeast is autolyzed and purified to obtain the bioactive peptide. The yeast-derived bioactive peptide is effective in relieving stress, nervousness, anxiety, tension, insomnia, fatigue, and imbalance in the autonomic nerve regulation. Therefore, the yeast-derived bioactive peptide is available as an anti-stress agent, an anti-fatigue agent, premenstrual syndrome and menstrual pain relaxants, a hain-neurotrophin, and a source of active foods having these activities.
