Light Exposure On Ascorbic Acid Concentration By Syed Imam On Prezi If a container of orange juice is exposed to a greater amount of light than another container, then the ascorbic acid concentration in the juice exposed to the most light will decrease faster, because a larger amount of ascorbic acid will be used to neutralize the formation of free radicals. There is a dearth of studies on the effect of pasteurization on aa in juices. this review attempts to propose a mechanism for the degradation of aa during ultraviolet (uv) and pulsed light (pl) treatments.
Ascorbic Acid Concentration Download Scientific Diagram This study has provided evidence to support the hypothesis that exposure to uv light and increasing the time exposed to uv light increases the degra dation of ascorbic acid in solution. The background information provided on ascorbic acid and its degradation process is relevant and well cited, and the chemistry is explained clearly. the methodology is appropriate, focused on answering the research question, and includes steps to ensure the relevancy and validity of the results. To investigate the degradation of ascorbic acid under the exposure of uv light. a redox iodine titration was selected to calculate the final concentration of ascorbic acid after uv light exposure. Discussion the vitamin c content in 25 ml samples of ascorbic acid solution was analyzed to determine the effect of uv exposure on degradation. the results generally supported the hypothesis, showing a correlation between increased uv exposure and vitamin c loss.

The document outlines a project on vitamin c in liquids, detailing factors affecting its stability such as temperature, light exposure, and oxygen presence. it emphasizes the importance of proper packaging and storage conditions to maintain vitamin c levels. It has been documented that l ascorbic acid is highly susceptible to light, undergoing oxidative degradation to dehydroascorbic acid, which subsequently further degraded into inactive. This work studied the effect of multi wavelength uv processing on the ascorbic acid content of aqueous solutions, at different ph values (3, 4, and 5). the source of radiation was a mid pressure mercury lamp (460 w), emitting between 250 and 740 nm. Discussion: the concentration of vitamin c (ascorbic acid) in orange juice is measured following heat exposure to determine whether processing vitamin c will speed up its decomposition.
