How to preserve spinach to increase nutritional value

Spinach is a delicious and nutritious vegetable. Proper storage will significantly increase the nutritional value of vegetables. Research published in the American Chemical Society offers better ways to preserve vegetables.

Spinach (spinach), delicious, nutritious food

Scientists Gene Lester, Donald J.Makus and D. Mark Hodges said: 'Supermarkets often store soy spinach in plastic bags at low temperatures and get a 24-hour glow with fluorescent lights'.

This has prompted scientists to wonder if this has an effect on the quality of spinach - the secret to the power of classic cartoonist Popeye.

Scientists have placed fresh vegetable leaves in the light or in the dark continuously according to the collateral storage conditions for 3-9 days.

The results showed that to spin spinach under light for 3 days will increase levels of vitamin C, K, El folate and vitamin B.

After 9 days, folate levels will increase by 84-100% and vitamin K levels will increase to 100%.

Vegetable leaves are also rich in carotenoids lutein and zeaxathin, 'coloring' ingredients for vegetables.

But the leaves of vegetables left in the dark tend to decline and do not change the nutritional value.
