The reason is that sugarcane needs a lot of nutrients during its growth. Sugarcane grows sweeter. On the one hand, the sugar produced after growing up will increase, on the other hand, the nutrients consumed will decrease, and the excess sugar will be stored in the lower part of sugarcane. Plants have the ability to protect themselves. Some of the produced nutrients are supplied for self-growth and some are stored. Therefore, the lower segment of mature sugarcane is sweeter than the upper segment. At the same time, thin cane absorbs less nutrients than thick cane, so thick cane is sweeter than thick cane.
2 How to choose the root of sugarcane as sweeter than the top? Sugarcane will consume nutrients during its growth, and excess nutrients will be stored in the roots. In addition, sugarcane needs to evaporate water during photosynthesis, and most of the water is concentrated around the top leaves, so the sugar is thin and the sugar concentration in the roots is high.
See if the pulp of sugarcane is fresh. Generally, fresh sugarcane has hard texture, milky white pulp and obvious fragrance. The pulp of moldy sugarcane is darker and lighter brown than normal sugarcane.
Sugarcane should be clean and sweet. Sugarcane in winter and spring is generally stored in autumn, which is easy to deteriorate, and flocculent white material appears at the end of sugarcane. There will be red filaments on the section after cutting, which may easily lead to food poisoning.
3 What kinds of sugarcane are there? Sugarcane can be divided into fruit cane and sugarcane according to their uses.
According to the shape, it can also be divided into sugarcane "Black King Kong", sugarcane "Black Green Gang" and sugarcane "White Jade Sugarcane".
Fruit cane is a kind of sugarcane specially used for fresh food. It has the characteristics of easy tearing, less fiber, moderate sugar content, crisp stem, delicious juice, good taste, thick stem, long node and beautiful stem shape.
Sugarcane, with high sugar content, is the raw material for sugar production, and is generally not used for fresh food in the market. Because of the coarse hard fiber and poor taste, it is only eaten fresh occasionally in the producing area.
