(6/12) This photograph shows a frozen state of the ink-containing water (500 ml water + 0.1 ml ink), in which we dissolved 0.1 g of AFP [1]. As shown, the water changes into a red-colored block of ice in the presence of AFP, implying that AFP inhibits the freeze-induced concentration (FIC) (movie). Note that when you freeze the colored water by using the high-power freezing instrument (-80 °C Deep freezer) or liquid nitrogen (LN2, -196 °C), FIC is also inhibited and the water similarly changes into a red-colored ice. A problem is that Deep freezer and LN2 supplying need a significant energy cost, while just a home freezer is okay for the AFP method. Basically any kind of AFP has the same effect, though we think that fish type II AFP and fungal AFP are the most effective. Next let us think about the reason why AFP inhibits the FIC phenomenon.
