摘要： The present invention provides a composition for inhibiting ice recrystallization, including: A nucleic acid structure comprising a scaffold nucleic acid folded at predetermined positions to form a plurality of strands, and a plurality of staple nucleic acids, wherein at least a portion thereof has a complementary sequence to at least a portion of the scaffold nucleic acid, thereby binding to the scaffold nucleic acid to form a double strand. Therefore, it is possible to increase a survival rate of cells due to having excellent effect of inhibiting ice recrystallization upon cryopreservation of the cells, and maintain a texture of food even when using the composition in the freezing of food.
