Enabling chlorophyll photo-response for in-line real-time noninvasive direct probing of the quality of palm-oil during mill process.

During the milling process of palm oil, the degree of palm fruit ripeness is a critical factor that affects the quality and quantity of the oil. As the palm fruit matures, its chlorophyll level decreases, and since chlorophyll in oil has undesirable effects on hydrogenation, bleachability, and oxidative degradation, it's important to monitor the chlorophyll content in palm oil during the milling process. This study investigated the use of light-induced chlorophyll fluorescence (LICF) for non-invasive and real-time monitoring of chlorophyll content in diluted crude palm oil (DCO) located at the dilution and oil classification point in palm oil mill.

(Z)-4-Chloro-N-(1-{2-[3-(4-chloro-benzoyl)ureido]eth-yl}imidazolidin-2-yl-idene)benzamide.

The title compound, C(20)H(19)Cl(2)N(5)O(2)S, was obtained from the reaction of 4-chloro-benzoyl isothio-cyanate with diethyl-ene-triamine. The imidazolidine ring is slightly twisted with an N-C-C-N torsion angle of 15.4 (4)°, while the thio-urea moiety maintains its trans-cis geometry.
