干縮的程度因空氣的條件(溫度、濕度、流速)、肉的等級和大小、包裝狀態(tài)而不同。當溫度高、濕度低、空氣流速快、冷藏時間長、脂肪含量少、形狀小、無包裝的情況下干縮量***增大。上述各種條件同時***不利時,可以使肉質(zhì)變?yōu)楹Ｃ逘铙w,使肉質(zhì)和脂肪嚴重氧化。這是因為在凍結(jié)冷藏時的干縮與冰的升華相似。在這個過程中,沒有水分的移動。因此,凍結(jié)肉表層水分蒸發(fā)后就形成一層脫水的海棉狀層。海棉狀層下的冰晶繼續(xù)升華,以水蒸氣的狀態(tài)透過表層,海棉狀層即由此而不斷加深。河北包裝冷凍肉貨物堆垛方式的選揮主要取決于貨物本身的性質(zhì)、形狀、體積、包裝等。</p><div

由于冰結(jié)晶的形成及一部分結(jié)合水的凍結(jié),使蛋白質(zhì)分子的水化層減弱甚至消失,側(cè)鏈暴露出來。同時加上在凍結(jié)中形成的冰結(jié)晶的擠壓,使蛋白質(zhì)質(zhì)點互相靠近而結(jié)合,致使蛋白質(zhì)質(zhì)點凝集沉淀。這種作用與凍結(jié)速度的關(guān)系極大。凍結(jié)的速度愈快,擠壓作用愈小,變性程度就愈低。其實也能吃，只不過口感不好而已。河北批發(fā)冷凍肉</p><p
