Default 警惕保鲜膜让食物变毒物

 保鲜膜对不同蔬果产生不同影响
  水分较大的水果和蔬菜比较适合用保鲜膜,比如苹果、梨、西红柿、油菜、韭黄等,不但能长时间保鲜,还会 增加其中的一些营养素。
  实验表明,健尔马足疗机多少钱,100克裹上保鲜膜的韭黄,24小时后其维生素C含量比不裹时要多1.33毫克,油菜、莴苣叶多1.92 毫克。但有些蔬菜的实验结果 却大相径庭,100克裹上保鲜膜的萝卜存放一天后,其维生素C含量减少了3.4毫克,豆角减少3.8毫克, 黄瓜存放一天一夜后,朗欣特足浴盆,其维生素C的损失量相当于 5个苹果,健尔马足疗机二代
  熟食不宜用保鲜膜包装贮藏
  熟食、热食、含油脂的食物,健尔马足疗机怎么样,特别是肉类,最好不要用保鲜膜包装贮藏。专家指出,这些食物和保鲜膜接触后,很容易使其材料中所含的化学 成分挥发, 溶解到食物中,对健康不利。目前市场上出售的绝大部分保鲜膜和常用的塑料袋一样,都是以乙烯母料为原材料制 作而成。有的保鲜膜材料是聚乙烯(简称PE), 这种材料不含增塑剂,使用起来相对安全一些;有的材料是聚氯乙烯(简称PVC),这种材料经常加入稳定剂、 润滑剂、辅助加工剂等原料,对人体有一定危害。 因此,在选择上一定要慎重。
  选择合适的保鲜包装
  如今,市面上食品包装产品有很多,比如保鲜膜、保鲜袋、保鲜盒等。董金狮指出:"保鲜主要是&rsqu o;保水’、’保质’和’保护营养’,在这 方面,保鲜 膜的功效最好。合格的保鲜膜透气性强,健尔马脊柱保,内外氧气可以交流,健尔马头颈宝,有效阻止厌氧菌的繁殖,在一定时间内,能保证食物新鲜。"但对于馒头点心这样的食物,用保鲜 膜显 然很不方便,相比来看,保鲜袋比较厚,透气性不是很好,相对适合一些,但使用时尽量不要把口封死。保鲜盒的 作用主要是密封,可以有效地将生熟食品隔离储 存,使冰箱空间利用率加大。
