Spring is the season of revival, the ice in the river melts, the earth is coated with a green coat, and the market is full of vitality. I don't believe you look at the vegetable farmer's stall, spinach, spring onions, leeks, children's vegetables, green shoots, spring shoots, and of course, asparagus, all reveal the tenderness, this is the unique umami taste in spring, must not be missed.
After a spring rain, one by one the asparagus emerged, becoming more and more emerald green under the sunlight. Asparagus, originating from the Mediterranean coast of Europe and Asia Minor, was originally a special vegetable for banqueting foreign guests, and was introduced to China in the early 20th century, until the 70s of the last century, when it began to be widely planted in China, and gradually entered the table of ordinary people' homes. Asparagus has a fresh taste, crisp taste, high nutritional value, and is known as the "king of vegetables". Its price has always been relatively expensive, especially the spring "head stubble" asparagus, the price is more than a dozen dollars a pound, but even so, can not stop people's love for it.
With the widespread cultivation and promotion of asparagus, its varieties have become more and more diverse, common green and white, in addition to a purple asparagus, so which one do we choose when buying asparagus in the spring? What is the difference between these 3 colors of asparagus? I consulted a vegetable farmer with many years of experience, he is one of my uncles, he told me that these 3 colors of asparagus in nutrition and eating methods have a big difference, the following to share with you, spring asparagus is delicious, figure out and then buy no loss, let's take a look at it ~
Green asparagus and white asparagus are two of the more common asparagus, especially green asparagus, which originally belonged to the same species, but in terms of planting methods are different, which is somewhat similar to leeks and leeks, garlic seedlings and garlic yellow.
Green asparagus grows under natural conditions, has sufficient light, photosynthesis produces chlorophyll, so it appears green. Green asparagus is rich in nutrients, especially rich in chlorophyll, multivitamins, folic acid, dietary fiber, protein, etc.
The reason why white asparagus appears white is because it is artificially intervened in the process of growth, and it is in an environment without light, so the planting process of white asparagus is relatively troublesome, the yield is lower than that of green asparagus, the material is rare and expensive, and the price of white asparagus is higher than that of green asparagus.
Because white asparagus has no light during the growth process and cannot photosynthesis, its mineral nutrition is higher than that of green asparagus. It is worth mentioning that the high content of vitamin E in white asparagus helps to fight oxidation. But on the whole, the nutritional content of green asparagus is more comprehensive, and the nutritional value is slightly higher.
From the perspective of eating method, green asparagus is mainly used for home-style consumption, can be fried, can be made into soup, and has many ways to eat. White asparagus is mainly used to make some more high-end dishes or canned food, especially in Western food.
Purple asparagus, generally refers to the American fruit type asparagus, its taste is more tender, the taste is sweeter, is a kind of asparagus that can be eaten raw directly.
Purple asparagus is purple in the same way as other purple fruits and vegetables, which stems from its internal anthocyanins, a natural antioxidant that helps delay aging. Because the purple asparagus has a faint sweetness, its sugar content will be relatively high, and the calories of the purple asparagus are higher than that of green asparagus and white asparagus, but despite this, compared with other vegetables, this bit of heat of the asparagus is still insufficient.
Since purple asparagus can be eaten directly raw, it is often used to make salads to eat.
Compared with the three types of asparagus, purple asparagus has the most tender taste and a more delicate taste, and the dietary fiber is not as high as that of green asparagus and white asparagus. If you are an elderly person or a friend with bad teeth, you can choose purple asparagus. The vitamin E and dietary fiber content in white asparagus is high, so friends who lose weight or diabetes can choose white asparagus. Green asparagus is the most common in our lives, and its nutritional content is somewhere between white asparagus and purple asparagus. Of course, no matter what kind of asparagus, its nutritional value is very high. You can choose according to your preferences.
No matter which kind of asparagus, picking a fresh purchase is the most important, the following 3 points to pay attention to:
1, look at the shape, fresh asparagus shape straight, generally for the head of the small root large, fine and thick, the transition is uniform, looks straight, and the epidermis is smooth and tight, rich in luster.
2, look at the top flower head, no matter what kind of asparagus, there are flower buds at the top, which can be eaten directly, when selecting, we have to choose the flower buds that have not yet bloomed, so that the asparagus is fresh. Be sure not to choose a bud that has already bloomed or a long bud, because the asparagus is already old.
3, pinch the root, we can use the nails in the root of the asparagus to gently pinch, if you can leave a nail print or can pinch out the water, it means that the asparagus is very tender, on the contrary, if you can't pinch it, it means that it is old.
The freshness of asparagus is easy to reduce, so the preservation of asparagus is very important, and it is best not to store more than 3 days, after all, the price is still relatively expensive, and it is not cost-effective to waste.
1, the newspaper preservation method, the remaining asparagus wrapped up with newspaper or absorbent paper, and then wrapped in plastic wrap on the outside, put into the refrigerator refrigeration preservation, this method can be maintained for about 3 days.
2, vase preservation method, the endless asparagus into the vase or similar container, the root is down, and then add the right amount of water, the amount of water is not more than one-third of the root of the asparagus, similar to our usual flower arrangement, this method can be stored for about 2 days, during the period pay attention to water change.
