Nutritional value of shiitake mushrooms

Shiitake mushrooms are delicious, fragrant and nutritious, and are known as the "Queen of Plants". In Japan, shiitake mushrooms and white fungus are both considered to be "miracle medicines" for anti-aging and longevity. Regular consumption can reduce blood cholesterol, prevent atherosclerosis, and is effective in preventing cerebral hemorrhage, heart disease, obesity and diabetes.

In recent years, American scientists have found that shiitake mushrooms contain a kind of "glucosidase", and experiments have proved that this substance has a significant effect on strengthening the body's anti-cancer, so people call shiitake mushrooms "anti-cancer recruits". Shiitake mushrooms can also resist cold viruses, because shiitake mushrooms contain an inducer of interferon, which can induce the production of dry leakage rock disturbers in the body, interfere with the synthesis of virus proteins, and make them unable to reproduce, so that the human body has an immune effect.

How to choose dried shiitake mushrooms

1. Ratio size

The small mushrooms are picked and dried when they are the most tender, so they are relatively high.

2. Look at the appearance

The shiitake mushrooms from Henan have a smooth surface and are not very strong in color. The ones produced in Fujian have more folds and are darker in color. The appearance of ordinary shiitake mushrooms is relatively smooth, and the color is yellowish-brown, while the color of high-quality shiitake mushrooms is much darker, basically black, and there are many folds on the surface.

3. Look at the process

Shiitake mushrooms are generally dehydrated and dried by machines. Some of the mushrooms are grilled or dried. The underside of the fire-roasted dried mushrooms is blackened and the machine is dehydrated.

The color is very normal and looks comfortable, and it is generally dried by itself when the yield is low. We can see that the appearance of the machine-dried shiitake mushrooms is uniformly black, the bottom of the mushrooms is white, which makes people look and feel comfortable, and the shape of the shiitake mushrooms roasted by this fire is relatively distorted. The surface color is dark and light, and the reverse color of the mushroom is also dark.

Not only that, but the water soaked in the two shiitake mushrooms is also different.

How to store dried shiitake mushrooms

1. Low temperature storage

Shiitake mushrooms must be stored in a low-temperature and ventilated place, and the container containing shiitake mushrooms can be sealed and stored in a refrigerator or cold storage if conditions permit.

2. Store away from light

The infrared rays in the light will heat up the shiitake mushrooms, and the ultraviolet search line will trigger actinization, thereby accelerating the deterioration of the shiitake mushrooms. Therefore, it is important to avoid storing shiitake mushrooms in bright light, and also to avoid packaging them with light-transmitting materials.

3. Sealed storage

The oxidation reaction is a necessary process for the metamorphosis of shiitake mushrooms, and if the oxygen supply is cut off, the oxidative deterioration can be inhibited. Shiitake mushrooms can be stored in sealable containers such as iron cans and ceramic jars, and the containers should be lined with food bags. The container mouth should be opened as little as possible, and the air in the lining bag should be discharged when sealing, and the oxygen and nitrogen filling bags can be used for storage if conditions permit.

4. Separate storage

Shiitake mushrooms have strong adsorption and must be stored separately, that is, the container containing shiitake mushrooms shall not be mixed with other items, and the warehouse where shiitake mushrooms are stored should not be mixed with other materials. In addition, shiitake mushrooms should not be stored in containers with odor volatilization or odor adsorbs.

5. Dry storage

Shiitake mushrooms have strong water absorption, and when the water content is high, it is easy to oxidize and deteriorate, and mildew will also occur. Therefore, shiitake mushrooms must be dried before they can be stored. The storage container must be filled with an appropriate amount of moisture absorbent such as lump lime or dry charcoal to prevent moisture back-flow.

1. Smell first, some unscrupulous traders will use formaldehyde to soak shiitake mushrooms in order to keep shiitake mushrooms fresh, if shiitake mushrooms have an unpleasant smell, they must not be bought;

2. Look at the mushroom cap, the mushroom shape is round, the mushroom meat is thick, and the lower volume of the mushroom cap is better beam infiltration;

3. Look at the size, not too big, not too small, the cap is better than 3 to 6 cm;

4. Look at the fungus folds, the white part is regular and neat, the surface is not sticky and slippery, and there is no mildew for the top grade;

5. Look at the stalk, the stalk is short and thick, the size is uniform, and the hand holds a hard feeling;

6. The normal color of shiitake mushrooms is yellow-brown, if the color of the oak ridge is black, moist and sticky to touch with your hands, or broken with your hands, and the edge of the mushroom cover is easy to fall, it means that the mushrooms are not fresh, and the acacia can not be eaten, so do not buy it.

Steps to choose fresh shiitake mushrooms:

A look: look at the color of the mushroom, the color of the good mushroom is light gray, a little whitish, if the surface of the mushroom cover has many white patterns, this is also called the mushroom, is the best quality. If you encounter some shiitake mushroom caps that are brown or black, and do not have any patterns, and feel wet, this is not delicious, and the taste is not fragrant, no matter how cheap it is, don't buy it, don't give it for nothing.

Second touch: Pick up the mushroom directly and feel it, the surface is dry. If the surface is wet and a little sticky, you need to give up.

There is also a slight pinch with your hands, and you should choose the kind that is soft, elastic and feels better. Some shiitake mushrooms look beautiful, but they are so hard that they can barely be pinched, and they are heavy, so it is recommended not to buy them.

Three inspections: If the above two points have passed, it is necessary to check the back of the mushroom, which is customarily called the mushroom cap, some of the mushroom cap has not been extended, some of the mushroom cap has just grown, and some have completely opened. Try to choose the mushrooms that have just grown, this is the best stage of shiitake mushrooms, they are neither tender nor old, and the nutrition and taste are the best.

Nutritional value: 1Shiitake mushrooms are rich in provitamin D, but vitamin C is very scarce, and they lack vitamin A and provitamin A.

2.Mushroom protein contains 18 kinds of amino acids, and among the 8 kinds of amino acids necessary for the human body, shiitake mushrooms account for 7 kinds, and most of them belong to L-type amino acids, with high activity, easy to be absorbed by the human body, and the digestibility is as high as 80%.

3.Shiitake mushrooms contain a lot of glutamic acid and umbelliferosine, which are rare in food, so the flavor is particularly delicious.

Steps to choose fresh shiitake mushrooms:

First, let's take a look at the cap and stem of the shiitake mushroom. When we choose shiitake mushrooms, we should choose shiitake mushrooms with the mushroom cap closed inside, so that the shiitake mushrooms are relatively fresh. This small detail is often overlooked when we buy shiitake mushrooms.

And we sometimes see that the mushroom cap of the mushroom has been opened, showing a loose state outward, such a mushroom is a stale mushroom, and such a mushroom will have cracks on the edge of the mushroom cap, so it is not recommended that we buy such a mushroom.

In addition, we have to look at the part of the mushroom stem, choose the color of the mushroom stem will not be yellow, and the milky white shiitake mushroom is a good shiitake mushroom. The shiitake mushroom handle should not be too slender, and you should choose a shiitake mushroom with a thicker stem and a fuller flesh, so that the shiitake mushroom is particularly fresh.

Although some shiitake mushrooms look similar to other shiitake mushrooms, the mushroom stalk part of the shiitake mushroom is very thin, and the shiitake mushroom presents an unnatural transition, which is not very fresh because the water loss is caused by the long picking time.

In summary, when choosing shiitake mushrooms, often just looking at the shape and size of shiitake mushrooms does not help us choose shiitake mushrooms well, on the contrary, these two small details of selecting shiitake mushrooms are always easy to be ignored by us. Therefore, it is recommended that we pay more attention to the part of the mushroom cap and mushroom stem, so that we can choose a more suitable mushroom. After observing these two parts, we take a look at the mushroom as a whole that is not damaged and relatively complete, that is, we need to choose the right mushroom, and observing the mushroom stem and mushroom cap of the mushroom will help us choose the mushroom.

The first point: look at the size of the mushroom, generally the big mushroom, it has more meat, and it is more refreshing to eat. As for the small shiitake mushrooms, its meat is relatively small, and it tastes very boring. Of course, buying shiitake mushrooms should not only look at the size, but should combine the following three points before deciding whether to buy or not.

The second point: look at the growth state of the stipe and cap of the mushroom, generally high-quality shiitake mushroom, its stipe and cap are evenly grown, and will not crook the melon and crack the jujube. If you see that the shiitake mushrooms grow unevenly when you buy them, don't buy them, because the shiitake mushrooms are not of high quality and don't taste so good.

Point 3: Look at the edge of the mushroom cap, it is normal to just pick fresh mushrooms, and its cap is curved inside. However, if the cap of the shiitake mushroom is warped outward, then it means that the mushroom is not fresh and has been picked for a long time, which will cause the cap of the shiitake mushroom to warp outward.

The fourth point: smell the taste of shiitake mushrooms, as the name suggests, shiitake mushrooms have a fragrance, I believe everyone has eaten shiitake mushrooms, and they also know what the taste of shiitake mushrooms is. When buying shiitake mushrooms, you can smell the shiitake mushrooms first, and if you smell the smell of shiitake mushrooms, then you can buy them with confidence.

But if you smell a rotten smell, then it means that the shiitake mushrooms are no longer fresh and should never be bought.

Such as and the selection of fresh mushrooms, jumping mushrooms must pick the thick leg, short such mushroom stir-fry out to eat the mouth is very meaty, its moisture content is also high, very nutritious, regardless of whether you are fried to eat, or stewed chicken is very good.

1. Look at the head. When choosing, look at the size of shiitake mushrooms, large shiitake mushrooms are better than small ones, because the meat is easy to keep fresh.

2. Look at the growth state. Looking at the growth state of the mushroom's stipe and cap, it is relatively well-proportioned, and if it is deformed, it is definitely not good.

3. Look at the color. Looking at the color and cracks of the cap, there will be pattern-like cracks on the cap of the mushroom of Youzhehong Finch, and the cap will grow evenly.

4. Look at the edges. Look at the edge of the mushroom cap, if the edge of the mushroom cap is bent inward at first, commonly known as the gong edge, it means that it is relatively fresh, if it has been, it means that the mushroom is relatively old.

5. Look at the stipe. If the shiitake mushroom stalk is relatively straight, not curved, thick, and not slender, the quality of such shiitake mushrooms is relatively better.

6. Look at the fungus folds. The folds are the part inside the cap, to see if the folds of the mushrooms are relatively symmetrical and fair. If the mushroom folds appear a little yellow, it means that the mushrooms are too old, picked too late, or picked and stored poorly, and left for a long time.
