R. DHANYA, B.B. MISHRA AND K.M. KHALEEL

Abstract

Fresh ginger rhizome is an important spice of medicinal and economic importance which are prone to spoilage during storage. Gamma irradiation preservation techniques are used to prolong the shelflife of these rhizomes. Gamma irradiation at the doses of 1, 3 and 5 kGy were carried out and volatile oil constituents of ginger rhizomes were analyzed by GC-MS. No statistical differences in volatile oil constituents were found between the radiation treated and control non-radiation treated rhizomes.
