【英语阅读】冷藏后的橙汁更健康

Orange juice is healthier for you if it has been frozen and defrosted, according to research.
  
Scientists have discovered the body may absorb more of the orange's antioxidants from defrosted juice than it does from fresh or pasteurised juice.
 
When orange juice is frozen and thawed out, health-giving elements of the juice are broken down into smaller particles which are easier for the intestines to soak up.
 
These particles, called carotenoids, are thought to have cancer-fighting properties, can be converted to vitamin A, and have anti-inflammatory and immune system benefits which may help to prevent heart disease.
 
The research by the University of Seville studied how freezing or pasteurising orange juice affected the antioxidants.
 
They believe freezing, which is done in the food industry to preserve juice, improves the healthiness of the juice and now hope to test their theory outside of the lab.
 
The study focused on what the scientists call the bioaccessibility of the antioxidants; that is, how available they are to be absorbed from the food into the blood by the intestines.
 
Absorption into the blood and building up in organs and tissues is how the antioxidants deliver their health-giving properties to the body.
 
Scientists discovered that during freezing the antioxidants – the carotenoids – become more accessible but they also deteriorate.
 
Although there are fewer carotenoids in the juice after it has been defrosted, what is left could be easier for the body to absorb, meaning the overall effect is positive.

研究表明，如果将橙汁冷冻和解冻，对你来说更健康。
  
科学家已经发现，身体可能会从解冻的果汁中吸收更多的橙色抗氧化剂，而不是从新鲜或巴氏杀菌的果汁中吸收。
 
当橙汁被冷冻和解冻时，果汁的健康元素被分解成更小的颗粒，这些颗粒更容易被肠吸收。
 
这些被称为类胡萝卜素的颗粒被认为具有抗癌特性，可以转化为维生素A，并具有抗炎和免疫系统的益处，可能有助于预防心脏病。
 
塞维利亚大学的研究研究了冷冻或巴氏杀菌橙汁如何影响抗氧化剂。
 
他们认为，在食品工业中进行冷冻以保存果汁，可以改善果汁的健康状况，现在希望在实验室外测试他们的理论。
 
该研究的重点是科学家们所说的抗氧化剂的生物可接受性;也就是说，它们是如何通过肠道从食物吸收到血液中的。
 
吸收到血液中并在器官和组织中积聚是抗氧化剂如何为身体提供健康的特性。
 
科学家发现，在冷冻期间，抗氧化剂 - 类胡萝卜素 - 变得更容易接近，但它们也会变质。
 

虽然在解冻后果汁中的类胡萝卜素较少，但剩下的东西可能更容易被人体吸收，这意味着整体效果是积极的。
