What is the difference between purple onion and white onion?

Difference 1: In terms of texture and taste, white onions will taste softer, the meat will be thicker, the juice will be more and sweeter, and the taste will not be very spicy. Purple onions, on the other hand, are more crispy, less watery, less sweet, and more spicy.

Difference 2: In terms of nutritional value, the vitamins and carotene in white onions are relatively high, and regular eating can effectively resist fatigue. The content of calcium, sodium, potassium and other mineral elements in purple onion is relatively high, and it also contains more dietary fiber and protein, which can effectively improve people's immunity.

At the same time, its anti-cancer and anti-inflammatory effects are also more pronounced than white onions.

The taste is different, white onions are not so spicy. Nutrition is not the same, white onions are better than purple onions in terms of nutrition, purple onions soaked in red wine, have great protection and ** effect on male prostate disease.

First of all, the varieties are completely different, the colors are completely different, one is purple, the other is white, and then the growing environment is different, the planting temperature is different, and the taste is different.

Onions are an ancient vegetable that has been eaten for more than 5,000 years. Abroad, it has"Queen of vegetables"Good reputation. Onions certainly live up to their name:

It is low in fat and rich in potassium, vitamin C, folic acid, zinc, selenium, dietary fiber, and special nutrients such as quercetin and prostaglandin A, which give onions additional health benefits. However, there are so many varieties of onions available in the market. Do you know what to choose?

White onions, yellow onions: higher content of carotene and vitamin C, better anti-fatigue effect. White onions have a lot of water and a sweet taste, which is suitable for eating raw; Yellow onions have a faint sweet and spicy flavor and are suitable for eating raw or with dipping sauces.

Choose heavy, dry, firm, and unscarred onions and store them in a cold, dry, dark, well-ventilated place. It should be noted that people with allergic rhinitis, asthma, ** disease and other allergies should eat less raw, and patients with gastric ulcers should also eat as little as possible.

<> onions, also known as green onions, contain a variety of nutrients, and spring and summer are the best times to buy onions. Although onions are spicy to eat, they are very delicious when cooked and are loved by people. It has"The queen of dishes"It is especially suitable for middle-aged and elderly friends.

Purple onions are more spicy than the other two types of onions, contain more water, and are also less expensive, but not easy to store. Buy onions, which one tastes good in white skin, yellow skin, or purple skin? It turns out that the difference is very big.

White onions are not as spicy as the other two, and their flesh is tender, watery, and sweet, making them ideal for eating raw. But because the yield is relatively low, it is relatively high. Only today did I know that the spicy taste of the yellow-skinned onion is in the middle, and the sweetness and spicinessness are balanced.

The meat is soft and delicate, making it more suitable for storage. This is very common in people's homes, and it is eaten as a vegetable, and this kind of export is also relatively common.

First of all, the color of the appearance is completely different, one is white, one is yellow, the other is purple, the nutritional value is different, the sulfide and anthocyanin content in the purple onion are very high, so it can achieve a particularly good antioxidant effect, and then can delay aging.

The difference is the difference in taste, the difference in taste, the difference in planting methods, the difference in color, and the difference in layering, so I think these colors are still very easy to distinguish.

The colors are different, the varieties are different, the taste is different, the production methods are different, and the tastes are different.

People who often buy onions will find a problem, there are three kinds of onions in supermarkets, especially in large vegetable wholesale markets: purple, yellow and white, so what is the difference between these kinds of onions and buffering? How should they be used?

Purple-skinned onions, spicy, heavier in taste, the strongest smell, the most rushing in the process of cutting, especially spicy eyes, people with sensitive eyes will have tears after cutting, talking about sneezing constantly. It is suitable for stir-frying, stir-frying with other ingredients. The most obvious changes are after cooking, first, the taste will change, and it will be a little sweet; The second is that the color will change, it will turn gray, which is not very good-looking, and affects the appearance of the dish, which is mainly caused by oxidation.

Yellow-skinned onions, the spiciness is lighter than that of purple-skinned, and the smell is also lighter, you can stir-fry, you can also eat raw, mix a cold dish or something.

White-skinned onions, mostly produced in the south, rare in the north, can not do without it to do Western food, commonly used in Europe and the United States, equivalent to our ginger, play a role in enhancing flavor and fragrance, this onion has the smallest flavor, but also a little sweet, so it is most suitable for cold salad raw food.

Purple onions are the cheapest and most common, but most restaurants don't like to use them, because they affect the appearance of the dishes, and they taste the most fragrant and suitable for home use. The price of yellow-skinned onions is higher than that of purple-skinned, and the spicy sweetness is moderate, and small and medium-sized Chinese restaurants like to use which old. White-skinned onions are relatively expensive, and they are the ingredients of cold dishes in medium and large Chinese restaurants and the essential seasoning of Western restaurants.

There is no difference, they can all be eaten with a very good taste, and we can all use them to make a match.

I think the difference is that white onions are not very spicy, the nutrients are better, and the best way to eat them is to fry onions or salad.

The difference lies in the different colors and the different nutritional values. I personally think it's better to scramble onion eggs directly.
