黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐与冷冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐早已成为每一个中国家庭的餐桌上的常客,不过要细问起来,大多数人却搞不清二者的差别。甚至有部分黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐或冷冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐的生产厂商也常常把二者混为一谈。如今,黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐安全与黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐健康愈来愈受到大家的关注,所以我们重新把概念普及一下,希望为您的生活品质提高提供点帮助。

冷冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(frozen and chilled foods)——冷却黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(chilled foods)和冻结黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(frozen foods)的合称。(因为对概念的不理解,所以这几个词的英语翻译很容易出错的,普通消费者是没关系的,专业厂商搞错了可是要闹笑话的。)

冷鲜肉冷却黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(chilled foods)——不需要冻结,是将黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐的温度降到接近冻结点,并在此温度下保藏的黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐。一般是0℃以上。

比如我们夏天在市场上买到的大部分外地产蔬菜,水果,鸡蛋,都是经过冷却处理的,现在流行的“冷鲜肉”(其实准确说法应为“冷却肉”),也是在0℃—4℃加工完成的冷却黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐。其优点在于不经过冻结,****程度地保持了食物的营养成分与口感,缺点是保质期相对较短,易变质,不能完全满足现代社会对黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐的便捷需求。

冻结黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(frozen foods)——是冻结后在低于冻结点的温度保藏的黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐。又可分为缓冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(slow frozen foods)与黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐(fast-frozen foods 或者 quick-frozen foods)两个大类。冻肉

我们把采取静态冷冻方式,缓慢冻结加工的黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐,称为缓冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐,以区别于黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐。在过去,经常吃的冻鸡,冻肉,冻鱼等等,都是缓冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐。这种黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐加工方法的特点是加工简单,成本低廉,保质期较长,一般加工温度为-29℃—0℃。黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐原材料一般来源于动物或植物,在缓慢的冷冻过程中,动植物细胞中的水,会变成大体积的结晶体(膨胀率会达到9%),从而导致细胞膜(壁)涨破。在解冻烹饪时,细胞内的营养物质就会随液态水而流失。同时,细胞中的部分蛋白质也会由于缓慢降温而产生变性。这就是人们常说的冷冻黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐不好吃,营养差的原因。

黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐一般是采用隧道库等现代设备,在30分钟内将黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐温度降至-30℃以下,随后保持在-18℃以下储存。因为在快速冷冻过程中,动植物细胞内的水分产生的冰结晶是小而细密的,不会破坏细胞的结构。蛋白质的低温变性也会由于温度的急剧下降而快速终止。因此,黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐可以保持相当好的营养价值与口感,同时还可以存放较长时间而不变质。满足了现代社会对黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐的健康,美味,便捷的综合要求。

了解了这些常识,我们就可以更容易地选择适合自己的美味黄金城YOPLAY_黄金城YOPLAY猜猜乐|电游YOPLAY猜猜乐,祝大家天天好胃口!
