A variety of fruits and vegetables, including raspberries, blueberries, Concord grapes, blackberries, strawberries, peaches, eggplant, red cabbage, and red onions, contain flavonoid compounds known as anthocyanins that are responsible for the blue-red color and the astringent taste associated with such foods. In addition, anthocyanins exhibit a wide range of chemical properties, such as.

Introduction The molecular spectroscopy is the study of the interaction of electromagnetic waves and matter.
UV-visible spectroscopy is a well-established analytical technique with mature methods and equipment. It is commonly used in both research and science as well as in industry. Applications are found in classic analytical fields such as in the chemical industry (mainly petrochemical and dyestuff industry), the pharmaceutical industry or in environmental analyses. Other fields of application are.
Ultraviolet-Visible Spectrophotometry: UV-Visible spectrophotometry is one of the most frequently employed technique in pharmaceutical analysis. It involves measuring the amount of ultraviolet or visible radiation absorbed by a substance in solution. Instrument which measure the ratio, or function of ratio, of the intensity of two beams of light in the U.V.visible region are called Ultraviolet.
The use of sensors (e.g., biosensors, spectroscopy) for bioprocess monitoring is widely seen as a powerful tool by the U.S. Food and Drug Administration (4,5,6).Spectroscopic sensors, when combined with PAT, enable simultaneous, real-time bioprocess monitoring of various critical parameters including biological, chemical, and physical variables during the whole production process (9,10,11,12).
He found that that photographic paper exposed to the rainbow will darken towards violet light (which is why we use red lightbulbs when working with unexposed film). When he put the paper beyond the visible violet light it quickly turned black due to ultraviolet (UV) radiation. UV radiation is responsible for the burns we experience when skin is.
