据中国之声《央广新闻》报道，现在正值冬枣上市销售的时节，最近网络上流传一个帖子称，在热水中加入糖精钠，将青色的冬枣放在这样的水中浸泡，短时间内青枣就会变成“红枣”。

According to the sound of China[Wide central news]reports,But during the winter date listed sales season,Recently the network spread a post said,In the hot water to join saccharin sodium,The blue winter jujubes on such soak,A short time will become elaborated"Red jujube".

　　据了解，在青枣成熟的过程当中原花青素会变成花青素，颜色所以会由青变红，而温度的升高会加速这一过程。在重庆有食品科学系的学生做了实验，他们把两份青枣放置在两个烧杯当中，其中一个加了甜味剂，即糖精钠，经过大约30分钟的加热之后，两份青枣的表皮都慢慢起了红点。而在他们看来，有甜味剂的那一份青枣变色更明显一些。在尝了之后发现，有甜味剂的青枣味道也微甜一些。如果糖精钠放得过多的话，青枣则会发出一种苦的味道，所以理论上来说，正常的青枣皮表皮是没有甜味的，如果消费者购买的冬枣表皮比果肉还甜的话，则可能说明是这是经过化妆的青枣。另外，这种青枣的表面会有黏黏的感觉，但正常的青枣表面是比较光滑的。

It is understood,Elaborated in the mature process when the central plains anthocyanin will become anthocyanins,Color so they will become red from green,But higher temperatures will accelerate this process.In chongqing have food science students do the experiment,They put the two elaborated placed in two of the beaker,One of the added sweeteners,Namely saccharin sodium,After about 30 minutes after heating,Two elaborated the skin is slowly up the red dot.And in their eyes,A sweetener copy of the more obvious discoloration elaborated some.In the taste found after,A sweet smell sweet also elaborated some.If saccharin sodium put too much words,Elaborated will send out a kind of bitter taste,So theoretically,Elaborated the normal skin epidermis is not sweet,If the consumer buys winter jujubes skin than flesh also sweet words,May be that it is elaborated after makeup.In addition,Elaborated the surface will be sticky feeling,But normal elaborated surface is quite smooth.

　　但是同一个实验可以得出不不同的检验，在广西检验检疫局国家农产品安全检测重点实验室，实验科学家在烧杯中放入了少许糖精钠，用冷水加入杯中，同时将几颗青色的冬枣浸泡其中，但是经过24小时的浸泡并且加大了糖精钠量之后，冷水加糖精钠泡的青枣仍然没有任何颜色的变换。专家表示，青枣由青变红并不是糖精钠的作用，而是热开水加温起了作用。他们也得出结论，加了糖精钠的青枣表面味道更苦，口感也并不好，而用热水浸泡之后的水果会影响其保鲜，加快其变质，所以网上的说法是不成立的。(记者沈静文）

But the same experiments can be concluded that different inspection,In guangxi inspection and quarantine state key laboratory of farm produce safety detection,The scientists in the beaker is placed in the little saccharin sodium,Use cold water to join the cup,At the same time will be a few a blue winter jujubes soak among them,But after 24 hours of soaking and increase the amount of saccharin sodium after,Cold water and saccharin sodium bubble of elaborated still don't have any color transformation.Experts say,Elaborated by green red and not saccharin sodium role,But the hot water heating played a role.They also concluded,Added surface of saccharin sodium elaborated more bitter taste,Taste is not good,And in hot water after soaking the fruit will affect its preservation,Speed up its metamorphic,So that the Internet is not established.(Reporter ShenJingWen)
