防褐变苹果来袭，刷新你的转基因食品观
<p>苹果削皮后如果不马上吃掉，没过一会儿整个果肉表层就会被氧化变成褐色，让人看上去毫无食欲。如今美国已经生产出了永不氧化变色的苹果，而且很快就要上市销售。不变色的苹果好是好，但因为这种苹果是转基因水果，到底还是让人心里不踏实。乐观的商家认为，如果这种苹果在市场上获得成功，就会打消人们对转基因食品的恐惧，但是批评者则认为，消费者还是应该保持怀疑态度。</p><p><span word="After">After</span> <span word="years">years</span> <span word="of">of</span> <span word="development">development</span>, <span word="protest">protest</span> <span word="and">and</span> <span word="regulatory">regulatory</span> <span word="red">red</span> <span word="tape">tape</span>, <span word="the">the</span> <span word="first">first</span> <span word="genetically">genetically</span> <span word="modified">modified</span>, <span word="non">non</span>-<span word="browning">browning</span> <span word="apples">apples</span> <span word="will">will</span> <span word="soon">soon</span> <span word="go">go</span> <span word="on">on</span> <span word="sale">sale</span> <span word="in">in</span> <span word="the">the</span> <span word="United">United</span> <span word="States">States</span>.</p><p>历经多年研发与非议，经受了监管部门条条框框的约束，终于，首款防褐变转基因苹果就要在美国开售了。</p><p><span word="The">The</span> <span word="fruit">fruit</span>, <span word="sold">sold</span> <span word="sliced">sliced</span> <span word="and">and</span> <span word="marketed">marketed</span> <span word="under">under</span> <span word="the">the</span> <span word="brand">brand</span> <span word="Arctic">Arctic</span> <span word="Apple">Apple</span>, <span word="could">could</span> <span word="hit">hit</span> <span word="a">a</span> <span word="cluster">cluster</span> <span word="of">of</span> <span word="Midwestern">Midwestern</span> <span word="grocery">grocery</span> <span word="stores">stores</span> <span word="as">as</span> <span word="early">early</span> <span word="as">as</span> <span word="Feb">Feb</span>. 1. <span word="The">The</span> <span word="limited">limited</span> <span word="release">release</span> <span word="is">is</span> <span word="an">an</span> <span word="early">early</span> <span word="test">test</span> <span word="run">run</span> <span word="for">for</span> <span word="the">the</span> <span word="controversial">controversial</span> <span word="apple">apple</span>, <span word="which">which</span> <span word="has">has</span> <span word="been">been</span> <span word="genetically">genetically</span> <span word="modified">modified</span> <span word="to">to</span> <span word="eliminate">eliminate</span> <span word="the">the</span> <span word="browning">browning</span> <span word="that">that</span> <span word="occurs">occurs</span> <span word="when">when</span> <span word="an">an</span> <span word="apple">apple</span> <span word="is">is</span> <span word="left">left</span> <span word="out">out</span> <span word="in">in</span> <span word="the">the</span> <span word="open">open</span> <span word="air">air</span>.</p><p>这种备受争议的“北极苹果”预计最早于2017年2月1日在美国中西部的多家商店以切片的形式进行初期的试点销售。因为经过了转基因改良，这种苹果的果肉暴露在空气中不会发生氧化变色。</p>
