疫情期间囤的速冻食品有没有营养？挑选时要注意什么？

一窝蜂2020-05-07

在2、3月份，

相信不少人家里都囤积着各种速冻食品，

如速冻饺子、速冻包子等，

以备不时之需。

不过，幸好我们国家物产丰富，鱼肉米蛋蔬菜水果等食物供应充足，速冻食品也就没能很好地派上用场了，只能继续乖乖地躺在家里冰箱的冰冻隔层。

什么是速冻食品？速冻食品有营养吗？

那么，话说回来，速冻食品到底有没有营养呢？

首先我们应该了解下什么是速冻食品。

所谓速冻，就是在强冷的环境下将食物的温度冷冻至-18℃的一种加工方法，而这个速冻过程，一般需要15分钟左右完成。

食品“被速冻”后，由于食物中的水分、汁液不会流失，微生物无法繁殖，不需要添加任何防腐剂，因此可以很好地保证食品的安全性，同时也能最大程度低保持食品的色泽、口感、组织状态及营养成分。

常见的速冻食品有速冻包子、速冻饺子、速冻糖原等，简单加热即可食用，既方便又美味，非常符合生活节奏快的现代人的需求。

综上所述，速冻食品在营养上不会有太大的损失，但就口感而言，速冻食品比新鲜食品口感略差。

速冻食品如何挑选？

1、看包装。选择包装规范的产品，注意查看商品标识是否明确，保质期、生产日期是否清晰地印在包装上。

2、看颜色。看食物本身是否发白、变色，如果发白可能说明储藏温度变化大导致水分散失干燥所致；如果食物变色，则有可能是已经变质了。

3、断是否粘连。购买速冻食品时，要注意观察食物是否粘连在一起，如果粘在一起，不要购买，因为可能存在解冻现象，而食品一旦解冻，温度就会超过-18℃，细菌就很容易滋生。

4、判断是否有冰霜。速冻食品是通过急速低温加工而成，若储存时间久了，食物表面就会出现较多的冰霜，不建议购买。

5、摸产品。购买速冻速冻食品，可用手触摸，判断是否存在变形、变软的情况。
