Description India is called as “spice bowl of the world” for its production of variety and
superior quality of spices. Spice products like Ginger oil and oleoresin has greater
demand in the International Export Market. Indian export of spice oil and oleoresins
is increasing significantly from 6600.05 M Tons in 2007-08 to 7264.86 M Tons in
2012-13. In view of the increasing demand, newer extraction technologies in
increasing yield of value added products viz., spice oil and oleoresins is necessary and
need of the day. With a view to achieve this aim, the present study was carried out in
two main directions. (i) Utilization of fresh ginger for the preparation of ginger
volatile oil and oleoresin with an added advantage of completely eliminating the
drying process of ginger, very much useful for ginger growing regions where enough
sunlight is not available which results in bacterial soft rot and sprouting of ginger. (ii)
Enzyme pre-treatment of fresh ginger with four commercial enzymes viz., Celluclast,
Pectinex ultra, and Herbal extraction enzyme and viscozyme to get enhanced yield of
oil and oleoresin.
The yields of volatile oil with enzyme pre-treatments were in the range of 0.66
- 0.79% as compared to control (0.54%). The yield of oleoresin was in range of 6.51%
- 7.87% as against control (5.86%). Celluclast showed 34.3% increase in oleoresin and
26.32% increase in the gingerol extraction. Ginger volatile oil and oleoresin obtained
by pre-treatment of enzymes showed higher value of alpha glucosidase and Tyrosinase
enzyme inhibitions. Ginger volatile oil exhibited antimicrobial activity against
Propionibacterium acne which can have a cosmoceutical application.
Enzyme pre-treatment of fresh ginger and extraction has shown promising
results in terms of yield of volatile oil, resin yield, gingerol content in oleoresin, higher
enzyme inhibition. The results of the present study can find direct application in Spice
oil and oleoresin Industries.
