There are more and more "bingtangxin apples" in the market. After opening, many apples will have a tangxin in the middle. Many people don't know how the bingtangxin is formed. Today, Xiaobian will come to popularize science for you.
Is "bingtangxin apple" a variety or a phenomenon
At present, the well-known "bingtangxin apple" is not a variety in fact. Its varieties cover: Red Fuji, Gala, Jinshuai, etc. It is not hard to know that "bingtangxin apple" does not refer to a variety, but a phenomenon.
Why does it form 'bingtangxin'
Deep study of the above mentioned "bingtangxin apple" can be attributed to the special phenomenon of some special varieties formed after they are fully mature in the plateau area.
(1) high altitude and large temperature difference between day and night are conducive to the formation and accumulation of fruit sugar.
At present, the production areas of bingtangxin Apple need to have high altitude, sufficient light and heat conditions and pure ecological environment.
(2) the key to sugar accumulation and enrichment is to irrigate snow mountain melt water.
The plateau water usually comes from the melting water of the snow mountain. The apples watered by the snow water are cool and sweet. The non sugar heart part is also full of sweet and crisp taste.
(3) super long growth period, strictly control the picking time to make it fully natural and mature.
The regular Apple has been on the market since September, while the plateau ice sugar apple usually goes to October or November.
The difference between "bingtangxin apple" and common apple
The difference lies in the 'ice sugar heart' formed by the accumulation of sugar in the fruit, and the sweeter and crisper taste it brings. Plain ice sugar heart ugly apple, born with plateau red, although the appearance is ordinary, but the aroma is rich, the taste is cool with snow water.
There are more questions about "bingtangxin"
Not every one has a candy core?
The answer is yes, because bingtangxin apple is a kind of phenomenon, not a kind of variety. Naturally, there is no guarantee that every apple has bingtangxin.
Sugar heart will disappear because of the rising temperature?
Of course, it is possible that the sugar heart will disappear due to the rising temperature, so the best storage temperature for sugar heart apples is - 5 to 5 degrees.
Why are the five ugly apples in bingtangxin?
1. Why is icy sugar heart Apple full of water and crispy?
A: in addition to the water content and crispness of bingtangxin Apple due to its unique geographical environment, another important reason is that the picking time of bingtangxin apple is strictly controlled after frost every year, the growth period is fully extended, and it is picked at low temperature, so the water content is special.
2. Why does bingtangxin disappear?
A: apples also breathe. Over time, sugar heart will gradually spread to the whole apple, which leads to the disappearance of sugar heart. But in fact, its nutrition and sugar content are not disappeared, just spread to the whole apple.
3. Why do some apples have no sugar heart?
A: there is a large temperature difference between day and night in the local area. The more abundant sunshine and frost, the more obvious sugar heart formed after picking. Because of the different growth position of an apple tree, the shape and significance of sugar center formed are different. And if the maturity of apple is not enough, it may cause sugar free heart, but it does not affect the taste. Because bingtangxin apple is a kind of phenomenon, not a kind of variety, there is no guarantee that every apple has bingtangxin.
4. Why is the core of very few bingtangxin apples black?
A: the black heart apple is the one near the core. This is a normal phenomenon. Due to the freezing weather in the flowering period, the black heart will appear when it matures after it survives tenaciously. You can eat it at ease and it has no impact on your body.
When you first cut the ugly apple, don't think it's broken. Don't worry. It's the Apple's fructose. Bite it boldly. It's crisp and crisp. It's like the taste of your childhood apple!
