    牛肉選購與保鮮

    發布日期:2014年11月17日 10:44

    【外觀完整】選購牛肉時,外觀是否完整很重要,肉必須要干凈,而且要選擇看起來濕潤度夠的牛肉。新鮮牛肉表面微干或有風干膜,觸摸時不粘手,聞起來也沒有酸、臭味。

    【色澤紅潤】大多數人選購肉食都會看肉的顏色,這無疑是正確方法之一。新鮮牛肉肌肉呈均勻的紅色,具有光澤,如果肉中含脂肪,要再檢查脂肪的顏色,其顏色若為奶油色或白色,那就是新鮮健康的牛肉。看到肌肉色澤呈暗紅,無光澤,脂肪發暗直至呈綠色的,須格外留意這是牛肉變質的征兆。

    【富有彈性】如果你用肉眼還是無法鑒別牛肉是否新鮮,可以用手指用力壓這塊牛肉,新鮮牛肉在指壓后,凹陷能立即恢復。指壓后的凹陷恢復較慢,并且不能完全恢復的是不太新鮮的牛肉。指壓后的凹陷完全不能恢復,并且留有明顯痕跡的就是變質牛肉了。

    【盡快吃完】購買牛肉時最好等到你所要購買完所有材料后,再去選購所需的牛肉。這點非常重要,這樣可以縮短牛肉在未置入冰箱前接觸常溫的時間。無論如何將牛肉買回家后應盡快食用,若不得已須放入冰箱保鮮,也應在2-3天內將肉吃完。特別是已經切過或調配醬料過的牛肉要盡快烹調食用,因為它已無法像整塊肉一般地長時間保鮮,所以食用時會損害其美味。

    【放入器皿】不要將牛肉泡在它自己本身所滲出的肉汁里。正確的方法應將牛肉放于有濾網的不銹鋼或塑膠器皿中,并最好以鋁箔紙封住容器開口。切勿使用塑膠保鮮膜以保持冷度。廚師建議:“肉片一次不要疊放兩片以上,以使肉片能完全接觸到冷空氣,而且最好的方法是將肉置放于冰箱中最冷的地方。”
