1, how is the rock candy apple formed?
The apple with rock candy heart is actually a red Fuji apple. However, after this kind of red Fuji apple took root in the Hongqipo Farm in Aksu, due to the large temperature difference between day and night at the foot of Tianshan Mountain, fructose accumulated well in the fruit, resulting in the natural condensation of sugar. When the fruit was cut open, the sugar accumulation was like the crystal of honey. This is the unique Aksu apple with excellent quality.
Akesu, the king of the world's apple kingdom, is the "rock candy heart" apple, which is only produced in the area around Fiona Fang, 30km away from Hongqipo Farm in Akesu region on the northern edge of Tarim Basin in southern Xinjiang. It has a unique warm temperate continental climate, a large temperature difference between day and night due to drought and little rain, a long frost-free period all year round, and a long illumination time. Relying on the Tomur Glacier in Tianshan Mountains, it is far from the polluted geographical conditions, making it an ideal home for developing organic agricultural products. "Hongqipo" apple has won the favor of consumers with its unique taste and unique internal quality, such as natural fruit color, excellent appearance, tender meat, rich aroma, sweet juice, crisp and refreshing, thin skin and no residue, and has a good product recognition and brand reputation. It has become a beautiful business card in Aksu and even Xinjiang.
2. The difference between rock candy apple and red Fuji.
The apple with crystal sugar heart grows in Aksu, Xinjiang, which is known as "the south of the Great Wall". It is a unique geographical and climatic environment there. Coupled with the characteristics of glaciers, rivers and sandy soil, it has created a unique phenomenon in the world. The core of the apple partially accumulates into a transparent state of ice crystal sugar, which is vividly called the apple with crystal sugar heart. Because in this special region, there is no such condition to grow and produce rock candy apples in other regions, which leads to the annual output of pure rock candy apples is very scarce.
There is no great difference between the appearance characteristics of rock candy apple and ordinary apple, but relatively speaking, because the rock candy apple grows in Aksu area, which is particularly cold in winter, the damage of pests and diseases is less, which makes the skin of rock candy apple smoother and more delicate, the color is very natural, and it looks particularly beautiful. The biggest feature of rock candy apple is that its core is the most special and unique transparent core made of sugar in the world, and besides this unique feature, the fruit picked by rock candy apple is very crisp, moist and crisp and sweet because of the special geographical environment.
