Objective:
Aloe-vera is now known to have various medicinal and cosmetic properties. A wide variety of
commercial products are available in the market, but these products have chemical preservatives
added in them which are found to have certain side effects. Our objective is to extract and
preserve the aloe-vera juice for further use without adding any preservative in it.

Procedure for juice extraction
The raw material (leaves) will be washed and cut down from edges to fed to the processing unit.
The juice extraction is carried out in a power driven machine. Thus, leaves are continuously
squeezed and extracted Squeezed liquor is collected in front and the extracted leaves at the rear
end of the machine. Residual juice from the squeezed leaves is also drained and collected. The
viscous clear transparent juice is then passed through a filtration-cum-homogenizing unit to get
clear, water white, transparent juice. The juice will be heated to 60-70 degree Celcius and then
rapidly cooled down so as to kill the microorganisms and hence there will be no need of any
chemical preservative or agent.
