- So my idea was born,and I had the project set up and a hypothesis,
- 这就是我的想法诞生的过程，然后，我就有了项目的开展和假说，
- so what was my next step?
- 那么我的下一步呢？
- Well obviously I had to find a lab to work at because I didn't have the equipment in my school.
- 很明显的，我要找到一家实验室，因为我在学校没有实验设备。
- I thought this would be easy,
- 我以为这会很容易，
- but I emailed about 200 different people within a five-hour radius of where I lived,
- 但是我给200多个人写邮件 ，离我居住的地方开车5个小时的范围内，
- and I got one positive response that said that they could work with me.
- 我只得到了一个正面的回复，说愿意帮助我。
- Most of the others either never responded back,
- 更多的人要么根本不回复，
- said they didn't have the time or didn't have the equipment and couldn't help me.
- 说他们没时间 要么就是没有设备，帮不了我。
- So it was a big commitment to drive to the lab to work multiple times.
- 所以说，这是一个很重的承诺，要多次开车去实验室开展实验。
- However, it was a great opportunity to work in a real lab --
- 但是，这是一个可以在真正的实验室工作的绝好机会--
- so I could finally start my project.
- 我也得以最终开始我的项目。
- The first stage was completed at home,
- 第一步是完全在家完成的，
- which consisted of marinating the chicken,grilling the chicken,
- 其中包括腌制鸡肉，烤鸡，
- amassing it and preparing it to be transported to the lab.
- 收集样本以及准备送到实验室。
- The second stage was completed at the Penn State University main campus lab,
- 第二步的完成是在宾州大的主校园实验室，
- which is where I extracted the chemicals,
- 也就是我提取化学物质的地方，
- changed the PH so I could run it through the equipment
- 改变酸碱度，这样我就可以通过设备
- and separated the compounds I needed from the rest of the chicken.
- 从其余的鸡肉中分离我所需的成分。
- The final stages,when I ran the samples through a high-pressure liquid chromatography mass spectrometer,
- 最后一步是，当我把样本经过高压液相色谱质谱仪，
- which separated the compounds and analyzed the chemicals
- 分开混和物质，并且分析其中的化学物质，
- and told me exactly how much carcinogens I had in my chicken.
- 于是我能很准确得知道在鸡肉中有多少致癌物。
- So when I went through the data,I had very surprising results,
- 当分析数据时，我发现了很惊人的结果，
- because I found that four out of the five marinating ingredients actually inhibited the carcinogen formation.
- 因为我发现五种腌制调料中有四种实际上能阻止致癌物的组成 。
- When compared with the unmarinated chicken,which is what I used as my control,
- 当同没有经过腌制的鸡肉比较时，也就是我的控制样本，
- I found that lemon juice worked by far the best,which decreased the carcinogens by about 98 percent.
- 我发现柠檬汁目前是最有效的，能降低致癌物达98%。
- The saltwater marinade and the brown sugar marinade also worked very well,
- 盐水腌制和红糖腌制也同样有效，
- decreasing the carcinogens by about 60 percent.
- 能降低致癌物达60%。
- Olive oil slightly decreased the PhIP formation,but it was nearly negligible.
- 橄榄油只能轻微的降低PhIP的组成，但是几乎是微不足道的 。
- And the soy sauce results were inconclusive because of the large data range,
- 酱油的实验结果还是未知数，这是由于广泛的数据范围，
- but it seems like soy sauce actually increased the potential carcinogens.
- 但是看上去，酱油实际上增加了潜在的致癌物。
- Another important factor that I didn't take into account initially was the time cooked.
- 另一个我没有事先预计在内的重要因素就是烧烤时间。
- And I found that if you increase the time cooked,the amount of carcinogens rapidly increases.
- 我发现如果增加烧烤时间，致癌物将飞速的增长。
- So the best way to marinate chicken,based on this,is to, not under-cook,
- 所以最好的腌制方式，根据这些（实验结果）也就是，不要生煮，
- but definitely don't over-cook and char the chicken,
- 但是一定不要煮过头和烤过头，
- and marinate in either lemon juice, brown sugar or saltwater.
- 用柠檬汁，红糖或者盐水来腌制。
- Based on these findings, I have a question for you.
- 根据这些发现，我有个问题想问你们。
- Would you be willing to make a simple change in your diet that could potentially save your life?
- 你们会愿意在你的饮食上做个简单的改变，由此可能会拯救你的生命？
- Now I'm not saying that if you eat grilled chicken that's not marinated,
- 我并不是说如果你吃没有经过腌制的烤鸡 ，
- you're definitely going to catch cancer and die.
- 你就一定会得癌症然后死去。
- However, anything you can do to decrease the risk of potential carcinogens can definitely increase the quality of lifestyle.
- 但是，你所做的任何事情来降低潜在致癌物质的几率，一定会增加你生活方式的质量。
- Is it worth it to you? How will you cook your chicken now?
- 对你来说，这值得吗? 现在你会怎么做鸡肉呢？
