为什么涨发好的海参不能冷冻?因为涨发后的海参组织内含有较多的自由水.自由水在0℃即可结冰.涨发后的海参冷冻时,首先细胞间隙中的自由水结成冰粒,使相邻溶液的浓度增大,渗透压升高,导致细胞内水分不断向外渗透,结果使细胞间隙存在冰粒不断增大.而且水结成冰后体积膨胀,对细胞产生挤压,进 Why the good hair good sea cucumber can not be frozen? Because after the rise of the sea cucumber tissue contains more free water.Free water freezes at 0 ℃ freezer.When frozen sea cucumber freezer, the first free water in the interstitial water junction Ice particles, so that the concentration of the adjacent solution increases, increased osmotic pressure, resulting in continuous infiltration of intracellular water, resulting in the existence of ice cell gap increased, and the volume of water after ice expansion, the cells produce Squeeze, into
