However, its calorie is very low, comparable to watermelon. For example, a 20-calorie Shatian pomelo (140g).

Listen to the sound when you knock and distinguish the quality of the fruit. It is best to choose a standard grapefruit with a sharp top and a wide bottom. The skin must be thin and smooth and light green or yellow in color. It would be better if it looked soft and juicy. The grapefruit just picked doesn't taste the best.

The growth and development of Guanxi honey pomelo need good ecological conditions: the annual average temperature is about 265438 0.2℃, and the soil PH value is between 4.8 and 5.5, so it is not suitable for shading.

The high grafting and early fruiting of mandarin oranges improve the cold resistance and fruit two years earlier than young trees. Guanxi honey pomelo has strong dryness, so it can be opened with large upright branches, with side windows on the upper periphery and small windows on the lower fruiting branches. Pay attention to cutting off dense branches, upright branches and vigorous branches. Young trees grow very vigorously, so reasonable girdling (stripping) is needed to promote their early production.

Edit this paragraph, citron tea.
Citron tea's raw material is a unique specialty of Korea, called yuja, which is called Jinyou in Chinese. It is refined from fresh grapefruit and honey by constant temperature cellar fermentation. Pomelo itself is rich in nutrition, containing far more calcium and vitamins than other fruits, and the content of vitamin C is three times that of lemon and orange. The content of calcium is 10 times higher than that of apples, pears, bananas and other fruits. Grapefruit is also rich in natural citric acid and a variety of inorganic salts, which not only contributes to the functions of liver, stomach and lung, but also has the effects of clearing heat, relieving cough and resolving phlegm. Citron tea's unique constant temperature cellar fermentation technology not only retains the original nutrition of fresh grapefruit, but also removes the bitter taste of grapefruit itself and decomposes some harmful ingredients. Due to the addition of natural honey, the trace elements needed by human body are further increased. In developed countries, people pay more and more attention to the role of grapefruit beauty beauty, which is highly praised by beauty lovers. Rich nutrition and unique aroma make citron tea a product highly accepted by consumers. Citron tea can drink hot and cold water directly, and black tea, green tea and jam can be added for dessert.

The wonderful use of grapefruit peel edit this paragraph.
1, grapefruit peel boiled water in the treatment of pneumonia in children.
After eating grapefruit, leave the skin to dry, put it in a pot and boil it with water (the decoction pieces should not be too small, otherwise the efficacy will be reduced, but it should not be too large), and the water should not be too much (like decocting Chinese medicine). After cooking several times, pour the cooked soup into a bowl for the children to drink, and it will be fine after drinking several times.
2, grapefruit peel boiled water to treat frostbite
Boil water with dried grapefruit skin. When it is very thick, use this water to hot compress the frostbite, but avoid breaking the skin. Pay attention to the temperature of hot compress. At first, the temperature of the towel should not be too hot, but it can be shaken with hot air. After getting used to frostbite, gradually increase the temperature. When the temperature is the highest, take the towel out of the pot and apply it directly. This method requires patience and long-term persistence (even if it is cured, it is best to persist until the end of this winter), which can promote the recovery of frostbite and effectively prevent the recurrence or reduction in the coming year. If there is no broken skin at the frostbite, you can add some dried peppers. It is best to use the pot and towel separately. Boiled water does not need to be changed, but it should be boiled every time. Adding new water must prolong the boiling time.
Step 3: Pickling
Method: Peel off the outer skin and pay attention to the blue ones, otherwise it will be a bit bitter. Then cut it into strips horizontally, paying attention to cutting it thin. Scald it with boiling water, then soak it in cold water for a day or two and change the water once or twice. When changing water, pay attention to squeeze the water out of the skin first, and then put it into new water (this will remove the bitterness). After a day or two, squeeze the skin out of the water and dry it a little. Then cook some sugar, cook it like water (you can put some in it if you want to eat spicy food), and put the skin in it and cook it together for a while. In this way, the grapefruit candy is ready.
4. Grapefruit is "brewed"
The method is similar to the above, except that the skin is cut into three or four pieces to form a triangle, and then each piece is carefully cut into a small mouth with a knife, and the prepared stuffing is put in (this stuffing can be used to make tofu according to everyone's taste). I remember it was boiled in boiling water, soaked in cold water for a day or two, squeezed out the water and brewed again. Just cook it again.
5, grapefruit skin buckle meat
Take 500 grams of pork belly and cook it according to the general procedure: cook it until it is 80% cooked-wrap the skin with sweet wine-drain the oil in the pot-take it out, cook it in soup and slice it. Slice pomelo peel, put it in the middle of each piece of pork, put it in a bowl, add salt, soy sauce and fermented soybean evenly, and steam it in a cage until soft and rotten. The white pulp of grapefruit peel can not only reduce the fat content of dishes, but also play a role in resolving greasy. Not only is the nutritional effect excellent, but grapefruit peel is a "good hand" in beauty.
6. It can prevent insects.
Tear off the white tendons inside, put them in a ventilated place to dry, and then dry the water. Put it in a bag with a small hole, which can be placed in the corner of a wardrobe or a rice bucket to prevent mosquitoes.
7. You can put it in the room to eliminate the odor. Putting grapefruit peel in the refrigerator can remove the odor in the refrigerator!
8, grapefruit skin shower gel
The homemade grapefruit skin bath lotion not only saves money, but also keeps the skin away from artificial chemicals. The most important thing is that the beauty effect is excellent.
Production method:
1. Cut the grapefruit into four pieces according to the cross, separate the skin from the pulp by hand, and then cut each skin into two pieces, so that one piece is cut into eight pieces.
2. Use a knife to separate the white part of the grapefruit peel (that is, separate the inner and outer skins), then cut the white peel into filaments and put it in a beaker. If there is no beaker, you can use ceramic or stainless steel utensils instead.
3. Add 0.5 ml of lactic acid or 0.5 g of citric acid to the white peel (adding lactic acid or citric acid is beneficial to the dissolution of pectin), add 200 ml of water, and cook directly on the fire for about 10 minute.
4. Filter out impurities such as white skin and extract. Then, about 200ml of water was added to clean the residue, so that the total filtrate reached 400ml.
5. When the filtrate is still hot, add 8g boric acid to dissolve it. Boric acid is a preservative, which can inhibit bacterial reproduction and kill mold.
6. When the temperature of the filtrate is cooled to below 40 degrees Celsius, add 40 ml of alcohol and 40 ml of glycerol. The amount of alcohol and glycerin can be adjusted according to the nature of skin: fine skin can be reduced to 30 ml, and coarse skin can be increased to 70 ml.
7. Finally put it in a beautiful empty bottle, and you're done!
