Carrot roots were sliced and frozen at –30 ◦C for subsequent
analysis of soluble solids, carotenoids and ascorbic acid content. On
the day of analysis rootwere kept out of freezer to obtain juice. The
extracted juices were collected in 50ml volumetric flask. Further
root samplesweremashed inmortar and pestle for juice extraction
and then the collected juice were mixed, and analyzed for soluble
solid content. About 0.4ml of the mixed juice was placed onto the
prism surface of pocket digital refractometer (PAL-1, Atago Ltd.,
Tokyo, Japan) and soluble solid contents were recorded. Repeated
measureswere conducted bywashing the prismsurface by distilled
water and also rinsed with the test juice.
