鲜榨就更营养？Freshly Made Juice Is Much More Nutritious?

大家好，

Hey Fam,

如果你是个ins迷，很可能你每天都会刷到欧美明星做完瑜伽后手拿一瓶冷压果汁，或是在巴厘岛正在进行一场果汁轻断食之旅，放下手机，走上街头，各种鲜榨冷压果汁店和超市的一排排冰柜货架的彩虹果汁瓶也是随处可见。但是在鲜榨和罐装好的冷压果汁之间，你清楚该选谁吗？眼前现榨的果汁因为看似新鲜就更有营养吗？本周我们就来说说两种榨汁方式背后的科学。

If you spend a lot of time on Instagram, chances are that you might come across a lot of celebrities posting pictures of them having a cup of cold pressed juice after a yoga practice or going on a juice cleansing in Bali Island. Back in the real world, there are a lot of cold pressed juice bars around. And the cold drinks display in the supermarket has been taken over by a rainbow of cold pressed juices.The question is: which one is better, the fresh squeezed juice or the bottled cold pressed juice? Is the fresh squeezed more nutritious because it is "fresh"? This week, we will explore the science behind these two juicing methods.

比起冷压果汁机，离心榨汁机最常见，可能你家里的橱柜此刻就放了一台。离心榨汁机的榨汁原理是利用金属刀片高速旋转，将水果蔬菜搅碎，看似很高效，几十秒的时间就能制作一杯果汁，但如果你注意到每次榨汁时发烫的机器及泛起的白色泡沫，你可能就注意到了这道工艺对食物营养的破坏了。高速旋转摩擦产生的热量造成蔬菜和水果的氧化，摧毁其主要营养元素和生物酶的活性,不仅仅损失了生物酶的活性，刀片切割了植物的细胞壁，很快就分解死亡，所以营养素分解的速度也比冷压果汁快的多。现在你知道为什么果汁店会建议你在15分钟内饮用完毕吧，因为在15分钟的最佳饮用期后营养便开始流失了。

Compared to cold press juicer, the centrifugal juice extractor is the most common type of juicer. You might even have one in your cupboard. Centrifugal juice extractors utilize a fast spinning metal blade to separate the juice from flesh. It seems to be efficient, as it could make a glass of juice in less than one minute. Yet you may find the centrifugal juice extractor actually damages the nutrients in fresh fruit and vegetables, if you have noticed the heat and the foam on top of the juice. The problem with centrifugal juicers is that the fast-spinning metal blade generates heat, which oxidizes those nutrients, and destroys some of the enzymes in the fruits and vegetables you’re juicing. The blade also breaks the plant cell wall, and consequently kills cells, leading the nutrients to break down faster. The reason why fresh juice is best served within 15 minutes? Because the nutrients are getting less and less after the first 15 minutes.

那冷压榨汁机又是怎么榨汁呢？冷压工艺是用压力将果汁从蔬菜水果中压出，第一步是将果肉碾压，再缓慢反复施加压力将全部果汁压出，因此不浪费任何一滴汁液，减少食材浪费的同时充分保留了水果蔬菜本身的营养和及微量元素酶的活性（因为制作过程中几乎没有热量产生），生的蔬菜水果中的酶是人体内植物营养素，维生素和矿物质的搬运工。冷压的过程中也压榨出更少的果肉，对于肠胃来说更好消化。冷压果汁不仅是制作后能继续保持酶的完整活性，甚至2－3天后都还保留着哦，所以我们说冷压果汁是能保存的鲜榨，更是鲜活的果汁。

Now let’s take a look back at the cold press juicers. These juicers extract juice by first crushing and then pressing fruit and vegetables for the highest juice yield. Because they don’t produce as much heat, they keep more of the fresh ingredients’ nutrients and enzymes intact. Enzymes are very important to the human body, as almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. At the same time, a cold press juicer will produce less pulp, and thus make the juice easier to be digested. Cold-pressed juice preserves valuable enzymes and vitamins for up to two or three days, so it is a real fresh juice, and a juice with a long shelf life.

频繁出入TRIBE餐厅的你，一定注意到了我们冰柜中摆放的一瓶瓶果汁，而每次点餐时服务员直接就给你倒了一杯而不是现场制作，你心里也总嘀咕“果汁没有当场制作能新鲜吗？营养成分没问题吗？“现在你应该理解了为什么我们没能在你眼前制作也同样能保证你摄入足够的营养了吧。因为比起离心榨汁机，冷压榨汁需要更多的前期切配准备工作，为了让更多的TRIBER在炎炎夏日最口渴的时候马上能喝到冷压，我们不得不提前准备好。当然了，虽然说新鲜的食材制作的冷压果汁最长能够保存至少3天甚至更长，但我们的果汁阿姨都会选择当天制作哟。

As a frequent visitor of TRIBE, you might have noticed those bottles of juice in our cold drinks display. Each time you order a fresh juice, instead of having a freshly made juice, you will be served with a glass of juice poured directly from the bottles. “Is that juice fresh, and nutritious?” Well, the answer is yes. It is the right nutritious juice even though we are not making it right in front of you. Because it usually takes a lot more time to prepare the fruit and vegetables using a cold press juicer than using a centrifugal juice extractor, we will have to make some amount of juice in advance. So a glass of cold pressed juice could be served right away if ordered by a most thirsty fam member in the summer time. Please be assured that even though the cold pressed juice remains fresh for three days or even longer, we only serve newly made juice on that day.

Centrifugal juice extractors are enough for daily home use. They are cheap, and they producejuices far more healthy and fresh than juice that's been packaged in cartons (which is full of additives). But if you want to get the maximum nutrients, please come to TRIBE for a cold pressed juice or order a take-away. A friendly reminder: cold pressed juice, as much nutritious and tasty as it is, should not be used as a meal replacement over a long period of time.
