Rapid quantification of specific carotenoid pigments in puree of mango and in products derived from thermally processed tomatoes by the Xe-lamp based photoacoustic spectroscopy

Autor: Doka, Otto, Bicanic, Dane, van Rooij, Hans, van Twisk, Charlotte, Luterotti, Svjetlana, Marković, Ksenija

In this paper the application of the photoacoustic spectroscopy (PAS) at visible wavelengths using Xe-lamp is discussed. This technique is used for rapid (without any need for pretreatment of the sample) and accurate assessment of beta carotene and l

Studying the extent of agreement between the photoacoustic and optothermal methods for assessing the amount of lycopene in foods derived from processed tomatoes

Autor: Bicanic, Dane, van der Veeken, Pascal, van Rooij, Hans, Dóka, Otto, Luterotti, Svjetlana

The consumption of lycopene, major substance in tomato was frequently demonstrated to have beneficial health effects. Methods most commonly used to determine lycopene include various forms of chromatography and spectrophotometry. The main problem enc

Photoacoustic (PA) spectroscopy and the Optothermal Window (OW) method both suitable for investigation of optically opaque samples were compared in terms of their capability to quantify lycopene in a variety of processed tomato-based products. The ex
