Abstract
(type = abstract)
Nine ginger powders from various parts of the world have been studied for their antioxidant strength by way of 1,1-diphenyl-2-picrylhydrazyl (DPPH) and oxygen radical absorbance capacity (ORAC). Of those tested, it was found that the acetone extract of Nigerian ginger from Synthite had the greatest antioxidant power. The extract was fractionated using the SepBox® and each fraction collected was tested for its ORAC value. The fractions with the greatest ORAC values are listed in increasing order, and were identified and confirmed by LC/MS/UV, MS/MS and HRMS: [6]-gingerdiol, octahydrocurcumin, [6]-gingerol, [4]-gingerdiol and hexahydrocurcumin. Select concentrations of each antioxidant were added to a single-fold Argentinian lemon oil, which were then placed in a thermally accelerated storage chamber for four weeks. Upon removal, the lemon oils were analyzed by GC, measured for their peroxide values and tasted by an expert citrus panel in a high-acid tasting solution. From the initial tasting, the two most preferred samples contained the antioxidants, tocopherols and tetrahydrocurcumin, which were also the two samples with the lowest peroxide values. Regarding the individual attributes, however, there weren’t significant sensory differences between the oils; therefore, the tasting solutions of these oils were placed in the chamber for an additional two weeks. The sequential tasting revealed that hexahydrocurcumin was the most effective antioxidant in preserving the flavor quality of the lemon beverage. These findings prove that incorporating antioxidants can improve the flavor and stability lemon oil.
