生的藕变红了还能吃吗
生的藕变红了不建议继续吃,因为藕变红其实是变质发霉的表现,这种藕可能会含有一定的黄曲霉素,而黄曲霉素是一种可以致癌的物质,同时还能诱发胃癌、乳腺癌、肾癌等癌症。
生的藕变红不建议继续吃
生的藕出现变红的情况时,不建议继续食用,因为藕变红是一种发霉的表现,通常是因为受到了细菌的侵袭并滋生大量细菌后,藕才会逐渐变红,继续食用这种藕会对人体健康造成较大损害。
发霉的藕里面会含有部分黄曲霉素,并且发霉越久的藕,含有的黄曲霉素会越多。而黄曲霉素是一种可以致癌的物质,同时还能诱发胃癌、乳腺癌、肾癌等癌症,因此平时最好不要吃变红的藕。
想要避免藕出现变红或变质的情况,平时可以将藕放在干燥、阴凉的地方保存,藕在很长一段时间内不会出现变质的现象。因为藕里面含有大量的粘液蛋白,所以藕比其它的蔬菜更容易存放。
藕发红了还能吃吗
如果是莲藕芯变红,可能是因为莲藕中含有的鞣质成分氧化导致的,这种情况可以食用,如果莲藕芯发红后还带有异味,口感也发生了变化就不建议继续食用了,有可能是莲藕发生了变质。莲藕中含有酚类容易与铁元素发生反应,所以尽量不要放入铁质容器保存。
藕发红了还可以吃吗
如果是莲藕芯变红,可能是因为莲藕中含有的鞣质成分氧化导致的,这种情况可以食用,莲藕煮久了也有可能会变成红色,因为水也中含有一定的氧气,煮久了容易进入莲藕中。
如果莲藕芯发红后还带有异味,口感也发生了变化就不建议继续食用了,有可能是莲藕发生了变质,食用变质的莲藕容易导致肠胃不适,还有可能出现腹泻等症状。
莲藕可以洗干净后放入非铁质的容器中进行保存,在容器中加入清水,每个星期进行更换,可以保存1个月左右的时间,也可以在容器内加入少量盐,可以防止莲藕被腐蚀。
吃藕时需要注意什么
莲藕中含有大量的酚类物质,与空气接触就会被氧化,所以尽量把莲藕放入水中浸泡,与空气隔绝,莲藕属于寒性食物,过多食用容易伤害脾胃,因为莲藕中含有酚类容易与铁元素发生反应,所以尽量不要放入铁质容器保存。
隔夜的煮熟的藕变红色了,能吃吗
隔夜的煮熟的藕变红色了,能吃,变红是因为藕与空气接触,被氧化了。
莲藕的维生素C含量高(每100克中含40~50毫克),还含有多酚类化合物、过氧化物酶,能把人体内的“垃圾”打扫得一干二净。
莲藕中含有比较丰富的优质蛋白质(约2%),其氨基酸构成与人体需要接近,生物学价值高。此外,莲藕还富含膳食纤维(2%左右),钙、磷含量也较高(钙为89毫克,磷285毫克)。
莲藕含铁量较高,常吃可预防缺铁性贫血。
富含维生素C和膳食纤维,对肝病、便秘、糖尿病等虚弱病症颇有裨益。
所含有丹宁酸有收缩血管和止血的作用,对淤血、吐血、衄血、尿血、便血者及产妇、血友病人极为适合。
可以消暑清热,是良好的祛暑食物。
新买的莲藕是红色的,能吃么
能吃的。变成粉色是里面的水分已经较少了。
只要不是黑色或是闻起来有酒味就可以
莲藕粉色有这样的品种。大紫红:原产江苏省宝应县。主藕4-5节,藕身长圆筒形,皮米白色,叶芽紫红色,花少,粉红色,中水位湖塘栽种,生熟食均可,品质好。
营养成分
宝应荷藕每100克可食部含蛋白质2.3克,脂肪0.1克,碳水化合物18.1克,钙18毫克,磷51毫克,铁4.4毫克,以及维生素b和维生素C。 生藕具有消瘀清热,除烦解渴,止血(鼻血、尿血、便血、子宫出血等)、化痰,治肺炎,肺结核、肠炎、脾虚下泻、妇女血崩等诸症。藕经过煮熟以后,性由凉变温,失去了消瘀清热的性能;而变为对脾胃有益,有养胃滋阴,益血,止泻的功效。
