Ps. Variyar et al., EFFECT OF GAMMA-IRRADIATION ON THE VOLATILE OIL CONSTITUENTS OF FRESHGINGER (ZINGIBER-OFFICINALE) RHIZOME, Food research international, 30(1), 1997, pp. 41-43
Volatile essential oils of fresh ginger rhizomes gamma irradiated (60
Gy) for sprout inhibition and non-irradiated control rhizomes were iso
lated by simultaneous distillation-extraction technique. Major compoun
ds present in these oils were identified by GLC and GC/MS analysis. Zi
ngiberin, beta-sesquiphellandrene and ar-curcumene were the major comp
ounds identified with zingiberin accounting for 40% of the essential o
il. gamma-irradiation at a dose of 60 Gy did not bring about any detec
table qualitative and quantitative changes in the aroma constituents o
f the spice immediately after irradiation. (C) 1997 Canadian Institute
