| 摘要 |
An objective to be achieved by the present invention is to provide an ice-crystal growth inhibiting substance which has an excellent ice-crystal growth inhibiting activity suitable for practical use and which can be produced easily, efficiently and economically in safe steps usable in food production. Another objective of the present invention is to provide a method for producing the ice-crystal growth inhibiting substance, a polypeptide which is an active part of the ice-crystal growth inhibiting substance, as well as an ice-crystal growth inhibiting substance composition, a food, a biological sample protestant and a cosmetic each containing the ice-crystal growth inhibiting substance or the polypeptide. The ice-crystal growth inhibiting substance according to the present invention is characterized in that the ice-crystal growth inhibiting substance is derived from a plant, and has a molecular weight of 400 kDa or more as measured by gel filtration chromatography. |
