Watermelon (scientific name: Citrullus lanatus (thunb.).) matsum.

et nakai) annual vine; The stems and branches are stout and have distinct ridges. tendrils stout, pubescent, petioles thick, pubescent; The leaves are papery, triangular in outline, with whitish-green bouts, with two masks with short stiff hairs, and the base of the leaves is heart-shaped. Monoecious.

Both female and male flowers are solitary in leaf axils. Male pedicels 3-4 cm long, densely pubescent with yellowish-brown flowers; calyx tube broadly bell-shaped; corolla pale yellow; The stamens are nearly detached, the filaments are short, and the chamber is curved. Female flowers:

calyx and corolla identical to male flowers; The ovary is ovate, stigma kidney-shaped. The fruit is large, nearly spherical or oval, fleshy, juicy, smooth skin, and varied in color and ornamentation. The seeds are numerous, ovate, black, red, smooth on both sides, obtuse at the base, usually slightly arched at the edges, flowering and fruiting in summer.

Watermelon can be called the "king of summer", refreshing and thirst-quenching, sweet and juicy, is a good fruit in summer, watermelon in addition to not containing fat and cholesterol, contains a lot of glucose, malic acid, fructose, protein amino acids, lycopene and rich vitamin C and other substances, is a rich in high nutrition, pure, edible safe food. The sugar content of pulp meat is generally 5-12%, including glucose, fructose and sucrose. The sweetness increases with the increase of sucrose in the late maturation period.

Watermelon pulp: protein, glucose, sucrose, fructose, malic acid, citrulline, glutamic acid, arginine, phosphoric acid, lactonine, propionic acid, ethylene glycol, betaine, adenine, sucrose, carotene, tomato hydrocarbons, hexahydrotomato hydrocarbons, vitamins A, B, C, and volatile components contain a variety of aldehydes.

Watermelon seeds: contain fatty oil, protein, vitamin B2, starch, pentosan, propionic acid, urea, sucrose, etc.

Watermelon rind: Watermelon rind is rich in vitamins C and E.

Hello, the sugar content of watermelon is higher, the main sugar friends of watermelon are divided into glucose, fructose and sucrose, etc., the sugar content of watermelon is about 6-8 grams per 100 grams, the sugar content will change with the maturity of watermelon, the higher the maturity of the general maturity, the higher the sugar content, although the sugar content is high, but watermelon is also rich in vitamin C, carotene, potassium and other nutrients, but also rich in water and fiber, which has good benefits for human health. Watermelon does not have a negative impact on health, but for diabetics, it is recommended to limit the consumption of watermelon or eat it reasonably under the guidance of a doctor<>

Watermelons are generally not high in sugar.

90% of watermelon is generally water, and the sugar content is not very high, about 8% of sugar per 100 grams, which contains fructose and sucrose, the fructose content in the congkai is higher than that of sucrose, and the energy content is about 25 kcal per 100 grams, which is not a high-calorie fruit.

The types of watermelon can be divided into fresh watermelon and seed watermelon. Most of the selected watermelon varieties were fresh watermelon, which was the main type of watermelon cultivation and had the highest degree of heterosis utilization among watermelon species. The seed watermelon has strong adaptability, high seed setting rate of side vines, and the management is more careless and extensive, and the selection of watermelon is the same as that of fresh watermelon. Inner Mongolia, Gansu, Xinjiang and other provinces and regions are the main producers of seed watermelons in China.

The origin of watermelon is in the arid desert region of tropical Africa, mainly cultivated in tropical areas, and has been cultivated in southern Xinjiang and Central Asia for more than 1,000 years. Watermelon likes a warm and dry climate, is not cold-tolerant, drought-tolerant, not moisture-resistant, likes light, requires a large amount of fertilizer, and is best in sandy soil with loose soil, deep soil layer and good drainage.

How to pick a watermelon

1. Look at the melon vines

The vines of fresh watermelons are tender and green, close to the picking time, and there is less water loss. If the melon vine is dry, it means that the watermelon is not fresh enough after picking for too long. In addition, looking at the melon navel can also distinguish the quality of watermelon, generally the melon navel is concave or the taste is sweeter with a small area.

2. Feel the epidermis

The skin of fresh watermelon is hard and smooth, and the flesh of the watermelon that has been left for a long time deteriorates, which affects the hardness of the peel and feels soft to the touch.

, elastic melon skin

Hold the watermelon in the palm of your hand and flick the rind with the fingers of your other hand. If the sound is muffled, it means that the watermelon is not ripe enough; If the sound is a crisp "dong dong" sound, it means that the watermelon seeps and is ripe.

4. Weigh the weight

In general, watermelons of similar size, raw melons are lighter than cooked melons. When choosing, you can weigh both hands at the same time and choose the heavier one.

Apples are higher than watermelons, the sugar content of apples is 15%, the sugar content of watermelon is 4% 7%, more than 93% of watermelon is water, diabetics can also eat a small amount, but watermelon is very high, calories per 100 grams are 25 thousand state calories.

Apples have about 100 kilocalories and a glycemic index between 34 and 38, and the calcium content in apples is much richer than that of ordinary fruits, which helps to metabolize excess salt in the body.

In general, tomatoes do not have a very high sugar content, but they also contain a certain amount of sugar, and different tomato varieties have different sugar content. Larger tomatoes are used in cooking, and smaller tomatoes are called cherry tomatoes and can be eaten as fruit on their own. The cherry tomatoes eaten as fruits are relatively high in sugar, but even though the cherry tomatoes in small tomatoes have a higher sugar content than large tomatoes, the sugar content is still lower than that of other sweeter fruits.

Therefore, tomatoes are generally low in sugar and can be eaten as fruits. Tomatoes are sugary, but they are very low in sugar compared to other fruits and vegetables. Diabetics can also eat tomatoes.

Tomatoes are rich in vitamin C, B vitamins, calcium, phosphorus, zinc, iron and other mineral elements. As an antioxidant, lycopene may reduce the risk of cancer and heart disease. Tomatoes can promote the secretion of gastric juice, promote digestion, and play an important role in maintaining ** and nerve health.

Contains vitamin C, which is not easily destroyed by cooking. Tomatoes are also the first choice for cancer prevention.
