    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>平时在超市购买皮蛋时,常会看到标签上写着<span style="color: black;">没</span>铅皮蛋,众所周知,铅不宜人体过量摄入,对人体有害,但若是从菜市场、零售店等场所购买散装皮蛋,很难知晓其<span style="color: black;">是不是</span>含铅。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span>,皮蛋<span style="color: black;">为何</span>会含铅,含铅皮蛋对人体有何<span style="color: black;">害处</span>,<span style="color: black;">没</span>铅皮蛋就真的<span style="color: black;">没</span>铅吗,<span style="color: black;">咱们</span>该<span style="color: black;">怎样</span>选购<span style="color: black;">安心</span>皮蛋呢?今天<span style="color: black;">咱们</span>就来为<span style="color: black;">大众</span>解答这些疑惑。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">01</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">皮蛋含铅,是<span style="color: black;">因为</span>在传统制作过程中加入了黄丹粉,这种粉又叫铅丹,<span style="color: black;">重点</span><span style="color: black;">成份</span>为氧化铅。皮蛋以鸭蛋为原料,包裹以生石灰、草木灰、茶叶末、盐、黄丹粉、稻壳调和而成的稀泥腌制而成,黄丹粉中的氧化铅<span style="color: black;">能够</span>在腌制过程中<span style="color: black;">逐步</span>渗入蛋内,使得蛋白质变性凝固,从而呈现出皮蛋独特的透明q弹的形态。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q5.itc.cn/images01/20240314/d21b92667845410199deb4326f46b528.bmp" style="width: 50%; margin-bottom: 20px;"></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">曾经有人对这种<span style="color: black;">办法</span>制作的皮蛋进行测算<span style="color: black;">发掘</span>,这种皮蛋中的含铅量约为3微克/克,若按<span style="color: black;">每一个</span>皮蛋净重60克,<span style="color: black;">那样</span>单个皮蛋的铅含量会高达180微克。若是<span style="color: black;">长时间</span>食用含铅的皮蛋,会对人体健康<span style="color: black;">导致</span><span style="color: black;">显著</span><span style="color: black;">害处</span>。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">02</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">若是<span style="color: black;">长时间</span>食用含铅的皮蛋,其所含的铅元素会对人体的神经系统<span style="color: black;">导致</span><span style="color: black;">极重</span><span style="color: black;">损伤</span>,除此之外,它还会对人体的消化系统和造血系统产生<span style="color: black;">很强</span><span style="color: black;">损伤</span>,即使<span style="color: black;">长时间</span>摄入量为微量,但若是摄入<span style="color: black;">连续</span>周期长,<span style="color: black;">亦</span>很可能<span style="color: black;">导致</span>消化道<span style="color: black;">流血</span>。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">儿童的消化道更为<span style="color: black;">敏锐</span>,对铅的吸收率可高达50%,若是儿童<span style="color: black;">长时间</span>摄入铅元素,其生长和智力<span style="color: black;">生长</span>会受到<span style="color: black;">极重</span>影响,其认知功能、神经<span style="color: black;">行径</span>和学习记忆等脑功能<span style="color: black;">亦</span>会受到<span style="color: black;">极重</span><span style="color: black;">损害</span>,更严重者<span style="color: black;">乃至</span>可能<span style="color: black;">导致</span><span style="color: black;">痴傻</span>。<span style="color: black;">按照</span><span style="color: black;">关联</span>数据,铅中毒<span style="color: black;">导致</span>的智力<span style="color: black;">损害</span>是不可逆的,即使<span style="color: black;">快速</span>下降血铅浓度,<span style="color: black;">亦</span>并<span style="color: black;">不可</span>使得智力恢复。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">03</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">事实上,<span style="color: black;">日前</span>市售的<span style="color: black;">没</span>铅皮蛋,<span style="color: black;">亦</span>并非百分之百<span style="color: black;">没</span>铅,只是在改进了制作<span style="color: black;">办法</span>之后,<span style="color: black;">再也不</span><span style="color: black;">运用</span>含铅化合物,其铅含量相比传统皮蛋大大降低,并远<span style="color: black;">小于</span>国标规定。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">相比较传统的制作工艺,现代的皮蛋制作采用符合《食品安全国家标准食品添加剂<span style="color: black;">运用</span>标准》(GB2760-2011)的食品加工助剂-硫酸铜代替传统<span style="color: black;">运用</span>的氧化铅,大大降低了皮蛋中铅元素的含量,<span style="color: black;">通常</span><span style="color: black;">来讲</span>,正规厂家生产的皮蛋,其铅含量与<span style="color: black;">咱们</span><span style="color: black;">平常</span>吃的肉制品、豆腐、鱼类等的铅含量相近,大多远远<span style="color: black;">小于</span>国家标准0.5mg/<span style="color: black;">公斤</span>,消费者们大可<span style="color: black;">安心</span>食用。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q1.itc.cn/images01/20240314/a9de1aabffa845d0baf469d60d40af59.bmp" style="width: 50%; margin-bottom: 20px;"></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">不外</span>,<span style="color: black;">针对</span>孕妇和儿童而言,<span style="color: black;">她们</span>的消化吸收能力更强,为降低<span style="color: black;">危害</span>,<span style="color: black;">咱们</span><span style="color: black;">通常</span><span style="color: black;">意见</span>孕妇和儿童不宜多吃,<span style="color: black;">或</span>少吃。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">04</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span>,<span style="color: black;">咱们</span>平时在购买皮蛋时,该<span style="color: black;">怎样</span><span style="color: black;">才可</span>购买到更加<span style="color: black;">安心</span>的皮蛋呢?<span style="color: black;">办法</span><span style="color: black;">重点</span>有以下几种:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1.<span style="color: black;">留意</span>皮蛋的外观。<span style="color: black;">通常</span><span style="color: black;">来讲</span>,铅含量和铜含量过高的皮蛋,其外壳表面会呈现较多斑点,若遇到<span style="color: black;">这般</span>的皮蛋,<span style="color: black;">特别有</span>可能是属于铅/铜含量超标的皮蛋,<span style="color: black;">咱们</span>不<span style="color: black;">意见</span>购买。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q8.itc.cn/images01/20240314/6b8360627c3c492d81ecdd54d5704b12.bmp" style="width: 50%; margin-bottom: 20px;"></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2.用手掂。在选购皮蛋时<span style="color: black;">能够</span>用手稍作掂量,若手感到皮蛋比较有弹性,则说明皮蛋的质量不错,较为<span style="color: black;">鲜嫩</span>;若皮蛋较硬,<span style="color: black;">无</span>弹性,则说明皮蛋可能<span style="color: black;">已然</span>不<span style="color: black;">鲜嫩</span><span style="color: black;">或</span><span style="color: black;">已然</span>变质。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3.晃一晃。握住皮蛋稍加摇晃,若皮蛋内部发出晃动声音,则说明皮蛋可能<span style="color: black;">已然</span><span style="color: black;">出现</span>变质,<span style="color: black;">引起</span>蛋黄流出,此类皮蛋不<span style="color: black;">意见</span>购买。<a style="color: black;"><span style="color: black;">返回<span style="color: black;">外链论坛:http://www.fok120.com/</span>,查看<span style="color: black;">更加多</span></span></a></p>
