食物谣言#2 冷冻蔬菜没有新鲜蔬菜有营养
Food Myths #2: Frozen veggies are less nutritious than fresh veggies.
有人说冷冻蔬菜的营养比新鲜的少
Some say Frozen veggies are less nutritious than fresh ones.

和奇妙的速冻世界吧
and wonderful world of flash freezing.

First of all, when vegetables are chosen for freezing,
的蔬菜来冷冻
they’re picked at the peak of their ripeness,
这些成熟蔬菜富含了最好的营养价值
which is also the peak of their nutritional value.
在它们被冷冻之前 先把它们浸入开水
Before they’re frozen, they’re dunked in boiling
接着快速冷冻来保证质量
water and quickly cooled to preserve their
避免污染及有机体的破坏
quality and to get rid of dirt and organisms.

Enzymes found in veggies help them grow and
但是成熟之后这些酶

When frozen, veggies will maintain their quality for a little over a year.
所以多亏了酶失活
So thanks to that enzymatic deactivation, your
冷冻蔬菜的营养会比放在架子上
frozen veggies may be nutritionally better off
新鲜成熟的蔬菜

on the shelf too long after peak ripeness.
