How to see if the watermelon is ripe, how to tell if the watermelon is ripe

1.Look at the fruit stalk: You can check the freshness of the watermelon.

The fruit stalk is green and tender, and has just been plucked by a living plant. If the fruit stalk is yellow, it is picked by rotten plants, and the quality is poor and not very fresh. 2.

Look at the shape of the fruit: You can check the sweetness and crispness of the watermelon. A good watermelon with a good fruit shape and plumpness, good development, and moderate sweetness and crispness.

3.Look at the peel: Check the thickness and freshness of the meat.

Watermelon with smooth skin, flat navel at the bottom, thin skin and fresh flesh. If the peel is wrinkled, the navel is large and concave, the skin is thick and the flesh is not fresh. 4.

Press the peel: You can check the freshness of the watermelon. If the skin is hard and elastic, the watermelon is fresh, and if it lacks elasticity, it means that the watermelon is ripe.

5.Listen to the sound: Tap the watermelon with your knuckles and listen to the sound to judge the ripeness of the watermelon.

In the water, the sinking water is unripe, and the floating water is unripe.

The following methods can be comprehensively considered: Because under suitable environmental conditions, the number of days from flowering to maturity of a certain variety is basically determined, such as 28 31 days for early-maturing varieties, 32 35 days for medium-ripening varieties, and 35 42 days for late-maturing varieties, so the method of calculating the number of days after flowering can be used to judge whether the watermelon is ripe. Different varieties of watermelon require a certain accumulated temperature from flowering to fruit physiological maturity, and it is a more accurate method to infer the maturity by accumulated temperature.

Generally, early-maturing varieties need an active accumulated temperature of about 800, medium-maturing varieties about 900, and late-maturing varieties about 1000. The peel and stalk characteristics of watermelons can be observed. The skin of ripe watermelon is hard and shiny, the pattern is clear, the color changes from fresh to deep, and the fruit pedicle shrinks slightly; Most of the hairs on the fruit stalk fall off, and in the state of no disease, the tendrils at the place of the melon knot are dry 1 2 or more.

Because after the watermelon is ripe, the flesh cells are filled with juice and the cells are filled with air, so when the fruit is patted with the hand, it will emit a low dull sound of "bang", and the palm of the melon will tremble slightly; The raw melon has a tight texture due to the melon pulp, and the fruit will make a crisp sound of "oooo In addition, the proportion of cooked melons is smaller than that of raw melons, so for watermelons of similar size, the lighter ones have a higher degree of ripeness.

Whether the purchase of high-quality watermelon is ripe is mainly identified by looking, touching, checking and listening.

See. Flower peel melons, the lines should be clear, and the shade should be distinct; Black melons, the skin should be black and shiny. No matter what kind of melon, the melon and the umbilicus are concave inward, the vine stalk is close to the skin of the melon, and the pedicle is thick and green, which is a sign of maturity.

Touch. Touch the melon skin with your thumb and feel that the melon skin is smooth and hard, and the melon skin is sticky or soft for the second melon.

OK. The more ripe the watermelon, the lighter its portion. Generally, watermelons of the same size are better for light ones, and raw melons for those that are too heavy.

Listen. Hold the watermelon in your hand, gently flick it with your fingers, and make a crisp sound of "dong, dong", and the hand of the melon feels a little trembling, it is a ripe melon; The sound of "sudden, sudden" is a reflection of a relatively high degree of maturity; makes a "poof, poof" sound, it is an overripe melon; It is the raw melon that makes the "click, click" sound.
