Korrelation der Farbcharakteristiken des Rapssamenöls

Abstract

Die vorliegende Arbeit befaat sich mit dem Vergleich von zwei alternativen Methoden zur Beurteilung des Raffinationsprozebses. Der Vergleich erfolgte anhand v a n 92 Proben aus 20 Betriebsversuchen zur Bleichung erucas3urcfreiem Rapssamen"l, Es wurde cine Korrelation zwischen dem Koordinatensystem nach Lovibond und dem Koordinatensystem der Internationalen Beleuchtungskommission CIE ermittelt. Hinsichtlich des cigentlichen technologischen Verfahrens so-Yhnlichen Schltissen. Correlation of the Rapeseed Oil Culuur CharacteristicsThe aim of the present study was to compare ods for the bleaching proccss evaluation. The 92 samples of rapeseed oil without erucic acid from 20 bleaching plant experiments were taken for this purpose, A conversion of [he ~~~i b~~d and [he CIE wie der ~~~~b~i~~~ der ~~~~i~b~~~~~~~h~ kame,, beide ~~~b~d~~ zu coordinate System Was found. The both methods gave the Similar results in relation to the bleaching plant experiments. Fat SCI. Technol. 95. Jahrgang Nr. I1 l Y Y 3

The Color of Olive Oils: The Pigments and Their Likely Health Benefits and Visual and Instrumental Methods of Analysis

“…However, the comparison between different methods for the color assessment of oils has also been the objective of several studies. For instance, the correlation existing between different instrumental and visual methods to measure the color of rapeseed oils has been determined (Brát and others 1988, 1993).…”

Reliability of the bromthymol blue method for color in virgin olive oils

“…Reciprocal conversions have been proposed between methods for evaluating the color of oils. In relation to plant bleaching experiments, Lovibond and CIE systems gave similar results (15). Tristimulus measurements have been carried out by diverse simplified methods in comparison with the CIE recommended procedure based on the whole visible spectrum, concluding that those simplified methods are only valid for certain purposes (16)(17)(18).…”
