The difference between white-skinned onions and purple-skinned onions is that white-skinned onions will be spicier, while purple-skinned onions will have a stronger aroma and a better taste when fried. Of course, purple-skinned onions are more nutritious.

The nutritional value of purple skin is higher, and the antioxidant capacity of purple skin is stronger, ** higher than that of white skin, and the nutritional value of white skin is not as high as that of purple skin and it is cheaper.

White-skinned onions have tender flesh, high moisture and sweetness, **-like color and rich sweetness, which are more suitable for fresh food, baking or stewing; Purple-skinned onions have reddish flesh and a strong spicy flavor, making them ideal for sautéing or making lettuce salads.

One white and one purple.

Onions are an indispensable vegetable for us to cook, and they can be fried as a vegetable, or they can be used as a seasoning when marinating some meat. But there are many varieties of onions, and the most common ones on the market are yellow-skinned onions and purple-skinned onions, so what is the difference between yellow-skinned onions and purple-skinned onions? Which one will taste bigger?

Difference Between Yellow-skinned Onion and Purple-skinned Onion1.Differences in taste

The biggest difference between yellow-skinned onions and purple-skinned onions is the difference in taste, purple-skinned onions actually have another name called shallots, which look purple or slightly red from the outside, and the internal color is also purple. Judging from the appearance alone, such onions will taste a little spicy, indeedThis purple-skinned onion will taste a little spicier and will have a heavier flavor.

Compared with purple-skinned onions, yellow-skinned onions are not only lighter in color, but also have more moisture in them and sweetness will be higher, so yellow-skinned onions and purple-skinned onions are compared, so the taste of yellow-skinned onions will be lighterIt is more suitable for stir-fryingPurple-skinned onions, on the other hand, can often be used to marinate some food to mask the fishy smell of the meat.

It should be noted that if it is a yellow-skinned onion, it is more difficult to preserve because the moisture in it is more abundant and the sweetness is relatively high, and the shelf life will be shorter.

2.Difference in nutritional value

Although these two are a type of onion, there will be a certain difference in nutritional value, and the protein content and mineral content of purple onions, as well as dietary fiber are very richAnd when these contents are combined, they are much higher than the overall content of yellow-skinned onions.

However, it does not mean that the nutritional value of yellow-skinned onions is relatively lowThe carotene content in yellow-skinned onions is very richIf you want to protect your eyesight, then it is best to eat more yellow onions instead of purple onions.

In addition to these benefits, purple onions are also bright because of their bright colorsTherefore, it contains anthocyanins, and after this anthocyanin enters our human body, it can delay the aging of our cells, and at the same time enhance the toughness and elasticity of our blood vessels, which is very beneficial to cardiovascular and cerebrovascular aspects.

3.Different ways of cooking

Because purple-skinned onions are relatively spicy, they are usually used to make barbecue or pickle some food, mainly to add aroma to food and mask the smell.

Yellow-skinned onions are usually more suitable for eating as a vegetable because of their rich juice. If you don't like the taste of cooking, you can also try to eat it raw or with dipping sauce, which is also a very good choice.

Yellow-skinned onions and purple-skinned onions are different in color and taste, the yellow-skinned ones are a little sweet, the purple-skinned ones are spicier, and the purple-skinned ones have a greater taste.

First of all, the color is different, and the taste, shelf life, and nutrition are all different. The flavor of the yellow-skinned onion is a little bigger, and the meat is particularly delicate, with good quality and high yield.

These two onions have different colors, different nutrition, different tastes, different shelf lives, and I personally feel that the taste of purple-skinned onions is greater.

The difference between white-skinned onions and purple-skinned onions is that they have different tastes, different nutritional values, and different storage timesIt is best to choose purple onions directly for stir-frying, because the flavor is a bit stronger。Onions are a very common ingredient, which is suitable for stir-frying or cold seasoning, and can play a role in enhancing the flavor. Most of the common onions in the market are divided into two types, namely white-skinned onions and purple-skinned onions.

Many people think that there is no difference between the two, but in fact, they are still very different.

First, the nutritional value is different.

Purple-skinned onions contain a lot of protein, anthocyanins, dietary fiber, and organosulfur compounds. Anthocyanins can play a role in alleviating aging, dietary fiber can help us prevent constipation, and protein can meet the various nutrients needed in our body, so both the elderly and children can eat more. The content of vitamin C and carotene in white-skinned onions is higher, which can help us improve immunity, prevent myopia, and alleviate eye aging.

Second, the taste is different.

White-skinned onions have a light, crisp and sweet taste, and do not have a characteristic spicy taste, so they are more suitable for cold salads. Due to the high content of vitamin C in it, it is easy to lose nutrients after heating, so it is not suitable for stir-frying. The purple onion has a heavier taste, and the taste is very spicy when eaten alone, which is unacceptable to make into a cold dish, so it is more suitable for stir-frying, and has a good flavor enhancement effect.

3. The retention period is different.

White-skinned onions are not resistant to storage because they have been dormant for too long, while purple-skinned onions are the opposite, because they have a long storage period, and as long as they are stored properly, they will not spoil even if they are left for about a week after being bought. It is precisely because of its characteristics that purple-skinned onions are more common on the market.

Onions have extremely high nutritional value, and it has been found that it can lower blood sugar, lower blood lipids, strengthen the spleen and stomach, and other effects. However, due to the warm nature of onions, if you eat too much at one time, it may cause fire, so you can't eat too many of the best things.

The planting environment is different, the taste is different, the taste is different, the color is different, and the purple onion should be chosen when stir-frying, because the purple onion contains anthocyanins, and the taste is particularly good, and the taste is particularly crisp and delicious.

Different colors, different appearances, different storage times, different uses, different tastes, and different nutritional values. Purple-skinned onions should be chosen when stir-frying.

There is no difference between white onion and purple onion in nutrition, and the differences in other aspects are:

1. Different colors: the color of white onions is white, the shape is spherical, and the flesh is relatively thick; The purple onion skin including the onion flesh is purple, and the meat is relatively thin.

2. Different moisture: The moisture content of white onions is higher than that of purple onions.

3. Different methods: white onions have more water and a sweet taste, so they are generally used for cold dressing and stir-frying; Purple onions, on the other hand, have a spicy taste and are generally used in cured meats to remove fish.

When you go to the supermarket to buy onions, I don't know if you have noticed that there are two kinds of onions in the supermarket, purple skin and white skin, generally we meet which one to buy, because the onion is still relatively cheap, but if the two are put together, we don't know how to buy, which is delicious, what is the difference, which is spicy, and I will talk to you today.

2.Ingredients:Although the varieties of white-skinned onions and purple-skinned onions are different, their composition is very different, white-skinned onions contain some vitamins and carotene, and purple-skinned onions contain more anthocyanins, so you can buy them according to your needs.

3.Storage time.

White-skinned onions are generally stored for a short time, it is best to buy and eat now, purple onions are more durable, if you buy more, it is recommended that you buy purple-skinned onionsThe difference between white-skinned onions and purple-skinned onions has been introduced to you, you can choose onions according to your preferences, and today I will introduce you to the practice of onions.

2.If you cut the onion for spicy eyes, you can first soak the onion in water for 10 minutes, so that the effect will be better.

Actually, there is not much difference, just the color is different, but if you want to mix cold dishes, we should choose purple onions with better color, but if you fry them, you should choose white beer shallots.

The protein, dietary fiber and other trace elements in purple-skinned onions are richer than those in white-skinned onions. The vitamins and carotene in white skin are higher than those in purple skin. Both have their advantages

The difference between the purple skin of the onion and the white skin is that the white skin is thicker than the purple skin, has more moisture, and is also more spicy. The purple skin is meager and slightly sweet, and can be fried and eaten, or it can be directly dipped in sauce. If it is a scrambled egg, it is still a white skin, which is light and appetizing visually, and the purple skin is a little faded and black and not good-looking, with slightly less moisture, and it is dry and has a bad taste.

Purple onions and white onions have different colors, different tastes, and different nutritional values, purple onions have higher nutritional value than white onions, and there are more antioxidants in onions than white onions, which can play a better role in preventing cancer.

There will be a noticeable difference. The taste is different, the proportion of allicin is different, the effect on the body is different, and the effect on the prostate gland in men is different.

Purple-skinned onions are a bit better.

Difference Between Purple-skinned Onion and Yellow-skinned Onion.

First, the nutritional value is different.

Compared with purple-skinned onions and yellow-skinned onions, there are many differences in nutritional value, and the "allicin" content in yellow-skinned onions is higher, so the spicy taste is more heavy; Purple-skinned onions are low in allicin and have a milder pungent flavor.

Purple-skinned onions contain natural anthocyanins, which can play an antioxidant role and are very good for the body; Whereas there is no such substance in yellow-skinned onions.

Second, the texture and taste are different.

The spicy taste of purple-skinned onions is lighter, the taste is more crisp, with a hint of sweetness, which is more suitable for cold dishes or raw eating, and will not lead to the loss of anthocyanins in Yanghe Sou onions; The spicy taste of the yellow-skinned onion is heavier, and the taste is relatively soft and glutinous, which is more suitable for stir-frying.

Three, ** different.

Friends who often go to the supermarket to buy onions must not be difficult to find that the purple onions and yellow onions in the supermarket are not the same, generally speaking, the purple onions are slightly more expensive, because the purple onions have less production and higher nutritional value.

The differences between purple-skinned onions and yellow-skinned onions are: different yields, different tastes, and different cooking methods.

1. The output is different

Onions are basically planted all over the country, but in terms of overall yield, the yield of purple-skinned onions is higher than that of yellow-skinned onions; Therefore, under normal circumstances, if two different colors of onions are sold at the vegetable stall at the same time, the ** of yellow-skinned onions will generally be slightly higher than that of purple-skinned onions. So there will be a slight difference on **.

2. The taste is different

Purple-skinned onions, also known as shallots in some places, have a purplish-red epidermis and dark purple internal tissues and bulbs. The water is less, and the taste is relatively spicy, but the aroma of onions is relatively strong;

In contrast, the taste of yellow-skinned onions is much milder, not as spicy as purple-skinned onions, and the moisture and sweetness are also higher than purple-skinned onions, with slightly sweet and soft flesh in the mouth.

3. Different cooking methods

The taste is different, so it will directly lead to a difference in cooking; Purple-skinned onions are generally used with some heavy mouths to evoke flavor, or when stewing meat, which is suitable for stir-frying with meat, which can reduce the spicy taste of purple-skinned onions and have a better taste.

The yellow-skinned onion is more watery and slightly sweet in taste, so it is more suitable for cold dressing, or daily vegetarian fried onions, onion scrambled eggs, etc. Plenty of moisture makes it crispier and juicier to eat.

How to choose onions?

1. Look at the shape

There are two shapes of onions in the market, one is oval with two pointed ends, and the other is round with two flat ends. Faced with two different shapes of onions, we want to choose an onion that is round and flat and has a large belly. Onions with round bellies have a higher content of both water and flesh than oval onions.

The oval onion with two pointed ends has a low moisture content and less flesh, and the resulting dish is not fresh and crispy, and the taste is not so fragrant. The short, round and round onions are crispy and sweet, and the taste is delicious. So we're going to pick short, fat, round onions.

2. Look at the top

When buying onions, we can look at the position of the top tip of the onion, and if the top tip has sprouted, then we don't pick. The pointed part of the top of the onion is the part where the onion connects to the stalk, so the onion is easy to germinate once it survives in an environment where the air is relatively humid and the moisture is relatively abundant. Sprouted onions have already started to lose their taste and nutrients, so it is not advisable to buy sprouted onions.

3. Look at the degree of dryness of the outer skin

In order to better preserve onions, onions are dried after harvesting. If the onion is dry enough, it can also inhibit onion germination, so we want to pick those onions that look drier on the skin. If the skin of the onion is damp or rotten, it is recommended not to buy it, the taste of the onion flesh has changed, and it can not be stored for a long time after buying it.
