The invention relates to a 
processing method of a concentrated sugarcane juice. The 
processing method comprises the following steps: aiming at the difference of the proportions of 
nutrient contents and 
flavor substances contained in sugarcane meat and sugarcane skins, respectively 
processing the sugarcane and the sugarcane 
skin into a concentrated sugarcane 
meat juice and a clarified sugarcane 
skin juice, and mixing and homogenizing to obtain the concentrated sugarcane juice. The processing method comprises the following specific steps: peeling the sugarcane to the obtain the sugarcane meat and the sugarcane skins, firstly carrying out squeezing, 
enzyme pre-destruction and sterilization, rough 
filtration, enzymolysis, 
ceramic membrane 
ultrafiltration and vacuum concentration on the sugarcane meat, then carrying out squeezing to obtain the concentrated sugarcane 
meat juice, carrying out 
enzyme pre-destruction and sterilization, rough 
filtration, enzymolysis and 
ceramic membrane 
ultrafiltration on the sugarcane skins to obtain the clarified sugarcane 
skin juice, finally mixing and homogenizing the concentrated sugarcane 
meat juice with the clarified sugarcane skin juice, and carrying out high-temperature instant sterilization, so as to obtain the concentrated sugarcane juice. The concentrated sugarcane juice prepared by virtue of the processing method is clear and transparent, has aromatic 
flavor and fresh, sweet and delicious taste, the original 
flavor and nutritional ingredients of the sugarcane are maximally preserved, and 
precipitation and a turbid phenomenon are avoided in a storage period.
