An improved process for preparation and preservation of sugarcane juice which comprises, a) soaking the canes in a tank containing potassium metabisulphite at 0.1% concentration and citric acid at 0.01% concentration for a period of 2-4 hrs, b) washing the canes obtained form above treatment with plain water, c) crushing the canes using a mechanical device to obtain the juice having 18-20° Brix, d) filtering the above juice using a centrifuge at a speed to 2000-2500 rpm at 22-28°C, e) diluting the clarified juice obtained after centrifugation with demineralised water till the total solid content is adjusted to 10-15° Brix, f) adding preservatives to the diluted juice such as potassium metabisulphite at a concentration of 70-140 ppm and citric acid at 0.2-0.3%, g) emulsifying the diluted juice with additives preferably xanthan gum at a concentration range of 0.01 to 0.10%, sodium alginate at a concentration range of 0.05 to 0.50%, h) homogenizing the emulsified juice obtained from the step (f) using a homogeniser at a speed of 10000 to 15000 rpm for a period of 5 to 10 min at 2000-2500 psi pressure, to get the desired sugarcane juice, the said process is characterized in that using additives xanthan gum and sodium alginate at a particular concentration range such as described above.
