When we choose asparagus, we will find that asparagus has two kinds of green and white, how to distinguish the quality of asparagus, the following Qi Ge will share a few skills for selecting asparagus.
There are two main types of asparagus, green asparagus and white asparagus, which can be distinguished from the color. Green asparagus and white asparagus are the same species, but the cultivation management methods are different. Green asparagus is exposed to sufficient sunshine, green, rich in nutrients, rich in chlorophyll, vitamins, folic acid, dietary fiber, protein, etc.; white asparagus is white without sunshine during growth, and the mineral element content is relatively high. White asparagus cultivation is more troublesome than green asparagus, and the yield rate is lower than that of green asparagus.
Overall, the nutritional value of green asparagus is slightly higher than that of white asparagus, and the price is also cheaper. Green asparagus is very suitable for ordinary people to cook to eat, and white asparagus is mostly used to make more high-end dishes and canned food.
1. Take a look
Fresh and high-quality asparagus is straight and thick, the skin is shiny, the spike tip is tight, and the length is about 20 cm. At the time of purchase, if you see the asparagus epidermis shrinking, cracking, mixed with black and yellow spots, it means that it has deteriorated. If the asparagus is found to have produced axillary buds, the base is older, indicating poor quality. Don't buy these two.
2. Take a sniff
Good asparagus smells like a very natural asparagus, if the asparagus smells putrid, it means that it has deteriorated, do not buy.
3. Pinch it
When purchasing, use your fingernails to gently pinch the roots of the asparagus, if there are imprints, it means that it is very fresh. In addition, fresh asparagus is more brittle and tender, and it will be broken by hand, if the fracture does not change color, it means that the quality is better. If the color difference between the fracture and the bamboo shoot meat is large, it means that the quality is poor.
1. The young shoots at the tip of the asparagus have the highest nutritional value and should be retained as much as possible.
2. Asparagus is easy to spoil, should be eaten fresh. If you really can't finish eating, you can blanch the asparagus for 1 minute, drain and let it cool, then put it in a plastic bag and seal it, and put it in the refrigerator for freezing.
3. Asparagus should not be overcooked, it is best to use a stainless steel pot. The use of iron pots and aluminum pots can easily discolor asparagus and cause a lot of vitamin loss.
