Spectroscopy and RGB-Colorimetry for Quantification of Plant Pigment and Fruit Content in Fruit Drinks
Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit content may be determined in a commercially available raspberry fruit drink. Another method, RGB colorimetry, which is a much more available techniqu
