走进各大超市,现场制作的主食厨房让人们有了更多选择。超市里的主食种类繁多,馒头、烙饼、花卷、油饼……如何选择才能兼顾营养与健康呢?对此,中国农业大学食品科学与营养工程学院副教授朱毅说,好主食应该符合以下4个
。 颜色发点黄 天然面粉中含有微量的胡萝卜素,所以直接用面粉加工后的主食都会带点黄。若颜色过白,则可能是增白剂的功劳,此外,这样的主食营养也低于其他同类产品。
面光滑、颜色过于均一的杂粮主食可能是色素美容后的效果,真正的杂粮主食有颗粒感,如玉米面馒头仔细看会有一些小颗粒,全麦馒头中也应该能够看到细碎的麦麸。 手感有点硬 很多人追求面食绝佳的口感,殊不知若馒头像面包一样松软,手一捏就剩一小团,很可能是因为添加了膨松剂;而杂粮面食,如果吃起来非常细腻,不是杂粮添加量极低,就可能是染色的假产品。总之,不管是哪种主食,手感不要太软,有点硬的是首选。 少油又少盐 油条、油饼、麻花等油炸面食应尽量少吃。炸食品时所用的油通常被多次使用,含有丙烯酰胺等有害物质,再者油炸时的高温会破坏食物里的大部分维生素,而且其高能量增加了发胖的危险。此外,从盐的角度分析,主食最好选清淡一点的,含盐多的花卷和千层饼等应尽量少选。 新鲜刚出锅 一般来讲,馒头放两三天后,就容易变硬发霉。所以,选购主食前,一定要看清生产日期和保质期,最好买当天生产或是现场制作的。此外,主食一次不要购买太多,实在吃不完的,要将其分装成一次可吃完的量,放在冷冻室中保存。 In each big supermarket, on-site production of staple food kitchen let people have more choice.
