Autumn wind, and it's the season to eat grapefruit. As we all know, grapefruit is a kind of nutritious fruit, rich in vitamins and dietary fiber, full of water, sweet and sour, cool and thirst-quenching. At the same time, it can clear away heat and promote digestion, and it is one of the fruits that must be eaten in autumn and winter.
However, in life, many people bought grapefruit, and after peeling it, they found that the grapefruit they bought was short of water, especially sour, and the taste was particularly poor. I don't know where your price is, but at least I have a grapefruit that is not cheap at all. A normal size is often around 20 yuan. If the grapefruit bought back is found to be not delicious, it is really tasteless and it is a pity to abandon it.
So, is it difficult to choose a sweet and juicy grapefruit? The answer is no, it is really not difficult to choose grapefruit, as long as you master the method.
In this article, I will share with you six tips for choosing grapefruit. As long as you choose according to these methods, you can ensure that the grapefruit you choose is thin and thick, sweet and sour, and full of water.
1 prompt to choose grapefruit, buy large ones instead of small ones.
Whenever we choose grapefruit, we will always find that grapefruit is dazzling and piled up like a mountain, which makes people wonder how to start at the moment. At this time, take a deep breath and tell yourself not to panic, which is the most popular. Why is this? Because, as long as it is the same variety of grapefruit, the thickness of the peel is similar, so the extra grapefruit is naturally pulp.
According to the calculation formula of sphere, V=(4/3)πR? You can find the cubic radius and determine the size of the volume. So even if the radius is similar, the gap is huge. A big grapefruit will have more pulp. On the contrary, small grapefruit will have much less pulp.
Although thrift has always been the virtue of our nation, in fact, the more you buy, the more cost-effective it is.
Of course, don't consider some big, abnormal grapefruit. In addition to being big, we have to comprehensively consider the following five points in order to select a good grapefruit. So please be patient.
The second trick to choose grapefruit is to buy yellow, not green.
This is a grapefruit hanging on a tree, and we can see that its position is different. Some grapefruit naturally occupy a high position, while others are low.
Grapefruit with relatively high branches is naturally sunny. With the rising and setting of the sun, the light is relatively uniform, so its overall color is beautiful yellow, and it is evenly distributed, and there will be no black Huang Zhi points. At the same time, because of the good maturity, the surface will be shiny and there will be natural fruit wax.
On the contrary, some pomelos droop, the sun is covered by leaves and other pomelos, and the whole will naturally be black and yellow. This kind of grapefruit is usually not sweet.
As for the overall blue grapefruit, it is generally not fully mature. Grapefruit has thick skin, insufficient moisture and sour taste. Don't buy such grapefruit.
However, there are always exceptions. At present, there is a kind of grapefruit called clear oil, which is native to the lowlands near Bangkok, Thailand. The appearance is short spherical, with high sugar content and low acidity. After being put on the market, grapefruit peel is still green, which is the result of the interaction of altitude, dimension and variety.
The third way to choose grapefruit is to buy short instead of long.
We picked up the grapefruit and looked at its head. This piece is not the same length. This place is also a place to hang branches.
Let's look at some pictures first. These are three periods of grapefruit growth and development, namely, fruit cell division period, fruit cell expansion period and fruit maturity period.
The first stage is the fruit cell division stage: it starts from flowering and lasts for about 7 weeks. During this period, the number of cells in peel and juice increased sharply.
The second stage is the fruit cell expansion stage: 50~ 140 days after flowering, lasting about 13 weeks. During this period, the weight and volume of fruit increased rapidly, mainly because the weight and volume of pulp increased greatly, and the peel became thinner after being slightly thicker. More than 70% fruit weight and more than 50% fruit volume increased during this period. During this period, if the sun, water and nutrition are sufficient, grapefruit will grow gratifying.
The third stage, fruit maturity: after flowering 140~ 180 days, lasting 5~6 weeks. At this time, the weight and volume of the fruit continued to increase, but the amplitude was very small, and the peel became slightly thinner, mainly due to the transformation of fruit contents (sugar content increased, acid content decreased, etc.). ) and the change of fruit color (green fades and yellow appears).
According to the above production process of grapefruit, we can know that grapefruit first grows the peel, then the pulp expands and develops, and finally becomes sweet.
At first, the head of grapefruit was long. With the expansion of pulp, grapefruit gradually becomes round and its head gradually becomes shorter. The shorter the head of grapefruit, the tighter its internal structure. This kind of grapefruit is mature, high in sugar and low in acidity, which will naturally be sweeter and more delicious. Therefore, you should choose grapefruit with short head and complete roots.
Some varieties of pomelo are born with a prominent head, such as Shatian pomelo and Wendan pomelo. So does this rule still apply? In fact, this rule still applies. We can still choose a shorter grapefruit, which will be sweeter.
The fourth trick to choose grapefruit is to buy concave instead of protruding.
Let's turn the grapefruit over and look at the bottom of the grapefruit. They all have a small dot in the middle of the bottom. Let's take a closer look at this position.
If you find the bottom of the grapefruit, this small circle is larger or concave, then congratulations, you have chosen the right grapefruit, which is usually sweeter.
On the contrary, the bottom ring is small and slightly convex, so grapefruit is usually not sweet.
The fifth trick to choose grapefruit is to buy hard ones instead of soft ones.
We picked up the grapefruit and gently pressed the grapefruit skin with our fingers. If you touch it. If you feel that the grapefruit skin is hard, it means that the grapefruit skin is thin and there are many pulps. As we said before, grapefruit grows the peel first, and then the pulp.
By the time the fruit is ripe, the size of the grapefruit has almost been finalized, and the main pulp has grown at this time. This situation is similar to tire inflation. When the pulp expands continuously, it will continuously squeeze the space of the peel, thus making the peel thinner and tighter.
On the contrary, if it is particularly soft to pinch, it must be thick skin, and there will be a thick sponge layer inside, so the pulp is naturally not big.
Therefore, you should choose grapefruit with tight skin, and it will rebound quickly when you click it. Simply put, it is hard grapefruit.
The sixth trick is to choose grapefruit, buy heavy and not buy light.
If two pomelos are similar in size, color and soft and hard shapes, how should they be chosen? We can pick them all up, weigh them with our hands and choose the heaviest grapefruit. The heavier the grapefruit, the more water it contains.
Some pomelos look beautiful, but they may not be new pomelos this year. Grapefruit has the reputation of canned vitamins, which not only shows that it has many vitamins, but also shows that it is as resistant to storage as canned food.
As long as the grapefruit is properly preserved, wrap it in plastic wrap and put it in the cold storage. When refrigerated at a suitable temperature for a period of time, the appearance changes little, but the water inside will be quietly lost. The longer grapefruit is stored, the more water will be lost.
If compared, it is only a little lighter, but this is only an individual difference. There are differences between twins, which is normal. However, if there is a big difference in weight, then you must be vigilant, indicating that there is something wrong with this grapefruit and it is not fresh. There is a good chance that it is grapefruit from previous years, so don't buy it.
Ok, finally sum up the formula for buying grapefruit, just six sentences.
"Buy big ones instead of small ones, yellow ones instead of green ones, short ones instead of long ones, concave ones instead of soft ones, and heavy ones instead of light ones."
These formulas are based on the experience of grapefruit growth and development.
