Navel orange 1, expectorant and toxic effect and function: Navel orange peel is a good Chinese herbal medicine. Dry and store. If there is a phenomenon of excessive phlegm and cough, you can take out a proper amount of orange peel and soak it in water, which can effectively eliminate phlegm and reduce adverse effects.
2, digestion and stomach: navel orange peel not only has the effect of phlegm, but also plays a role in digestion. Pickled tangerine peel sold in the market is a snack that can strengthen the stomach and promote digestion by using the digestion of orange peel.

5, cure bad breath: cut off the surface secretion of orange peel to dry, often cook soup to drink.
6, cancer prevention: navel orange can remove free radicals harmful to health in the body and inhibit the growth of tumor cells. Among all fruits, citrus contains the highest antioxidant.

It is good for vomiting caused by food accumulation and pathogenic wind in the stomach, liver and stomach stagnation.
Navel orange: 1 was chosen just to see if there was an anti-counterfeiting label on it. But this trick doesn't work now. Even the anti-counterfeiting logo of Yangcheng Lake hairy crabs is fake, not to mention this small navel orange. Ok, let's say the simplest point. Larger merchant credit is ok. Since there is a label on it, believe it.
2. Look at the appearance. Gannan navel orange is generally a little oval, not round. Round oranges are of course oranges, and there may be delicious varieties. But today we are talking about Gannan navel orange, a domestic high-quality variety, and any fruit is not as big as possible, just as moderate.
3. Look at the color. The color is orange, which is a natural peel color. The color of inferior navel orange is blue; Gannan navel orange is best not to buy, its color is bright and red, and it feels very delicate and smooth. This navel orange is waxed and polished, which looks good, but the price will be higher if there is one more processing step; Secondly, waxing and polishing will affect the normal breathing of navel orange surface. Although the taste and quality of navel orange will not be affected, the shelf life of navel orange will be shortened. So look at the picture below me. This is the most natural color of the peel. Although I took photos today, I didn't scrub the fruit to ensure its original state.
4. Look at the pores of the peel. This is definitely my personal experience. As we all know, there are many pores on the surface of navel orange peel. Be careful not to choose a pore that is particularly thick, because the thicker the pore, the thicker the peel will be. If you don't believe me, pay attention next time, so that the pores are moderate and even. But without pores, the skin is particularly smooth and the quality is not good.
5. It is also a misunderstanding of many people. Some people say that this Gannan navel orange is male and female, and that the big navel is female and the small navel is male. I looked up a lot of information and bought two oranges with different navel. Some people think that the one on the left has an umbilical cord, while the one on the right does not. There are actually two kinds of navel oranges. One is the one on the left below, which is called umbilical exposure, and it should be concave inward. I also looked it up on the Internet, and experts from Agricultural University said there was no such thing. Therefore, it is a misunderstanding to say that navel orange is completely exposed. Of course, in the case of all exposed umbilicus, relatively speaking, concave is more mature than convex, and the taste is naturally better.
6. Judging freshness: There are two methods. One is that if it is the freshest, then the shoots at the top of the navel orange have not fallen off and the leaves have not completely withered, but it is impossible to make the leaves completely fresh. Generally, we see leaves, which means they are still fresh, because they will fall off over time; The second is to press by hand, which is very important. If the skin is firm and elastic (which is also important), it means it is fresh, and so on. If the skin is loose and almost separated from the pulp, it means that there is a lot of water loss inside, so it is recommended not to buy it.
Select note: 1. Usually, if you peel oranges by hand, you will feel very inconvenient. It's actually quite simple. All you have to do is roll the orange a few times to soften the skin, and it will be easy to peel it. However, many people find that the nails will be stained with the color of oranges when they are planted, and it is difficult to clean them. This is very simple. Taking a plastic bag when peeling can solve this problem.
2. In addition, choosing navel orange according to fruit navel is also a shortcut to judge the quality of navel orange. Choose navel orange with small navel and no bulge. The smaller the navel, the better the taste. Real high-quality navel orange, the navel is only about one millimeter.
