TL;DR: In this paper, β-Carotene was added to soybean salad oils to study its effect in inhibiting flavor deterioration due to light exposure, and the results showed that β-carotene significantly decreased formation of 2-heptenal and 2,4decadienal in the absence or presence of citric acid.
Abstract: β-Carotene was added to soybean salad oils to study its effect in inhibiting flavor deterioration due to light exposure. Flavor evaluations indicated that (a) when oils treated with citric acid were exposed to light (7535 lux) for 8 to 16 hr, oils containing 5 to 10 ppm β-carotene showed improved flavor stability compared to oils containing 0 to 1 ppm β-carotene; and (b) when oils were not treated with citric acid, only oils containing 20 ppm β-carotene were more stable to light. Capillary gas chromatographic analysis showed that the addition of 1 to 20 ppm of β-carotene significantly decreased formation of 2-heptenal and 2,4-decadienal in the absence or presence of citric acid. Determination of peroxide values showed the same trends as gas chromatographic analyses of volatiles. In the presence of 15 and 20 ppm β-carotene, some off-flavors, as well as poor ratings for color quality, were reported by panelists. Therefore, flavor deterioration initiated by light can be inhibited effectively in soybean oil, without affecting color quality, by addition of β-carotene at concentrations from 5 to 10 ppm to oils treated with citric acid.

TL;DR: In this article, a bacterium with high poly(γ-glutamic acid) (γ-PGA) productivity was isolated from soil and identified taxonomically as Bacillus subtilis with the exception that it could not assimilate citric acid.
