The Effect of Time and RPM on the Saponification Process to Get High Carotenoids

Abstract

Red palm oil (RPO) is derived from the FFB of palm oil. Carotene in red palm oil or red palm oil cannot be obtained by ordinary processes. Various attempts were made to obtain carotene compounds by various methods of separation (extraction). Therefore, this study attempted to study the effect of the time and rotational speed of the rotary evaporator on the yield of carotenoid concentrates formed in the saponification process so that it would produce optimum carotenoid concentrates seen from the content of carotene and DOBI produced. The sample used was crude palm oil (CPO) which was processed in stages, namely transesterification, solvates micellization (SM), and saponification. The treatment was carried out in the saponification process, namely stirring time for 1.5 hours and 2 hours with each rotating speed of 1800 rpm, 2000 rpm, and 2200 rpm. In each process, carotenoids and DOBI values will increase. In the saponification process, the best treatment that produces high carotene and optimum DOBI is the stirring process at a speed of 1800 rpm for 1.5 hours. The time of stirring in the saponification process has a real effect on the value of carotene and the DOBI index.

“…Los resultados obtenidos para el contenido de α y β-caroteno se presentan en la figura 2, evidenciando un incremento significativo (p<0.05) en las muestras tratadas con US en las etapas de licor de prensa y entrada al preclarificador en comparación con la control (ACP) en aproximadamente un 30%, debido a que el US fracciona las moléculas grandes de triglicéridos en moléculas más simples (ésteres metílicos de ácidos grasos) cuyos niveles de solubilidad son mucho más altos, generando que los carotenoides se separen de manera más sencilla (Cherie et al, 2022). En la figura 2, letras distintas en las columnas son diferencias mínimas significativas según la prueba de DMS-Anova (p<0.05) entre los tratamientos para cada etapa del proceso.…”
