Food Myths: Frozen veggies are less nutritious than fresh veggies.
食物谬论:冰冻蔬菜不如新鲜蔬菜有营养#-[4Y*ydNBxGcu~

Some say frozen veggies are less nutritious than fresh ones.So let’s take a walk through the wild and wonderful world of flash freezing.
有人说冰冻的蔬菜不如新鲜的蔬菜那么有营养Icsi52I]j))05K~k4[。所以,让我们探访一下狂野精彩的速冻世界Xd6*8+t+82yV

First of all, when vegetables are chosen for freezing, they’re picked at the peak of their ripeness, which is also the peak of their nutritional value.
首先,当选择蔬菜进行冰冻的时候,是在最为成熟的巅峰期采摘的,也就是营养价值的巅峰@5+&MaM3Ta5xKfBGv

Before they’re frozen, they’re dunked in boiling water and quickly cooled to preserve their quality and to get rid of dirt and organisms.
冰冻之前,先用沸水浸泡,然后迅速冷却至储藏温度,消除污垢和微生物tts13-!W))

It’s a process called blanching.
该过程叫做热烫NCxYC7k.!OL@L9X7E

Enzymes found in veggies help them grow and ripen but after peak ripening, these enzymes will begin to break down the vegetables,and reduce their nutritional value.
蔬菜中发现的酶帮助它们生长和成熟)fKsh%x1]^~*p0y%=O2n。但是成熟的巅峰期过后,这些酶开始分解蔬菜,破坏其营养价值(ArQKCLS9m0XH

Blanching deactivates this enzyme induced breakdown and only causes a slight loss of some water soluble vitamins.
热烫可以阻止酶造成的分解,只会造成少量水解维生素的流失5%fJg|zYtcs_)8m

When frozen, veggies will maintain their quality for a little over a year.
冰冻的时候,蔬菜会维持其质量超过一年的时间]r_f[6T4-7m#v

So thanks to that enzymatic deactivation, your frozen veggies may be nutritionally better off than fresh ones that have been sitting on the shelf too long after peak ripeness.
由于酶失活作用,冰冻蔬菜在营养方面比那些摘下来之后长时间放在架子上的新鲜蔬菜还要好7.q;qjz*K+&u

So yeah, frozen is a go!
所以,放心选择冰冻蔬菜吧Piyk.eP5L#FzMIax

A US-led coalition has carried out over a dozen airstrikes against Islamic State militants in Iraq and Syria.

vAD+2(hoYmUb+9YAP

A US military statement says 12 air raids hit ISIL targets near the Iraqi cities of Mosul, Kirkuk and Ramadi. A further five air strikes hit militant positions in Syria. This comes after the US and its allies carried out 14 airstrikes in the two countries on Thursday.

With the help of the US-led airstrikes, Kurdish forces have been able to drive the militants out of the autonomous Kurdistan region in Iraq. But ISIL remains a major threat in the country. Meanwhile, in Syria, the militants have established their de-facto capital in Raqqa, and control much of the surrounding area.

Chinese companies has invested $65.2 bln in US

China says that the United States is now the Chinese mainland's third-largest outbound direct investment destination, after Hong Kong and Australia.

t)AJ;bZ.d.

Vice Minister of Commerse Zhang Xiangchen, said Chinese enterprises had set up over 3,000 companies in the United States by the end of 2014, and had invested over US$ 65 billion, providing nearly 80,000 jobs through direct investment.

^)R[Z4jRihl.*OrNCS+O

But due to the relatively late arrival of Chinese investors, this still only accounts for one percent of the US's total foreign direct investment. Zhang also commented on the potential rate rise by the U-S Federal Reserve, saying that, if implemented, it will only have a limited impact on China's investment in the country.

Of course the host country's macroeconomic policies, including interest rate policies, will be put into consideration when Chinese companies make investment moves. but more importantly, they will seek their development opportunity from the perspective of global industry.

)y*Aa#@V3iK[73dC-s

Data over the first eight months of this year shows Chinese companies remain highly interested in investing in the US. China and US are highly complementary in the areas of investment, so we believe Chinese investment in the US will cotinue to grow at high-speed," Zhang Xiangchen said.
