A method for recovering the ice nucleating protein from the ice nucleating strain and a method for increasing the activity of the ice nucleating protein

摘要

The present invention provides a method for recovering a flight-reforming protein from a microorganism, a method for increasing the activity of an ice-nucleus forming protein, and a method for promoting freezing of a food by adding an ice-breaking protein with increased activity to the food.;According to the present invention, by treating Pseudomonas viridiflava with EDTA and Triton X-100, a large amount of ice nucleating protein can be recovered without loss of ice nucleating activity, The present invention relates to a method for producing a protein which comprises administering one or more compounds selected from phosphatidyl inositol, And the mixture is subjected to ultrasonic treatment to form a liposome composed of an ice nucleating protein and a phospholipid to increase the ice nucleating activity of the protein.
