The water content of the cane, apart from sugar and fibre, is over 70%. The water is cellular raw water in sugarcane plants and contains more free radicals which are beneficial to human bodies. In addition, the sugarcane plant water is screened layer by layer through living cells, so that the sugarcane plant water is more beneficial to the absorption of human bodies, the minimum amount of water can be drunk by human bodies in activities or sports, the most efficient water supplement is obtained, and the effects of promoting the secretion of saliva or quenching thirst are achieved. Therefore, if the part of water in the sugarcane can be fully utilized and processed into drinking water, not only can the resource of the drinking water be enriched, but also the additional value of the sugarcane can be improved. Sugar manufacturing enterprises directly discharge water extracted from sugarcane into a waste water tank without reasonable utilization, the method not only increases the pressure of terminal waste water treatment, but also greatly wastes water resources, and the water treatment needs huge resources every year. The invention extracts the cell water in the sugarcane plants to prepare high-end drinking water, converts the traditional production mode of the sucrose industry from the original single sucrose-used target product into a novel production mode of multi-element products and high-value products, can greatly prolong the industrial chain and the value chain, and has good economic benefit and great social benefit. The technology of the invention not only can relieve the current problem of global water resource shortage, but also meets the requirement that people increasingly pursue good and healthy life, conforms to the concept that consumers pay attention to food safety and diversified markets, and integrates the modern science and technology and healthy life concepts. The method and the technology provided by the invention change the sugar industry of sunset into the sugar cane industry of sunrise, change the pattern of the sugar industry in the world and make a new contribution to the development of the economic society of Guangxi.
