TL;DR: In this article, the effects of UV-C illumination on postharvest quality and bioactive compounds of yellow bell pepper during refrigerated storage were investigated, and the results showed that UV-c illumination at 6.6 kJ m-2 showed the best results in maintaining firmness and reducing the increase in weight loss and electrolyte leakage.

Influence of Postharvest Temperatures on Carotenoid Biosynthesis and Phytochemicals in Mature Green Chili (Capsicum annuum L.).
TL;DR: 30 °C is the recommended incubation temperature for mature green chili to achieve the industry-demanded intense red color and high accumulation of phytochemicals and the observations suggest that the expression of individual genes is temperature-dependent, and these would affect specific carotenoid compounds.

TL;DR: In this article, a colourimetric method was described for the measurement of free ascorbic acid in plasma using methylene blue, which was converted to the colourless leucomethylene blue by asbric acid in conditions of strong light.
