Adulteration of butterfat: validity of Reichert-Meissl, Polenske and iodine values

Abstract: RESUMEN Adulteración de grasa de manteca: validez de los índices de Reichert-Meissl, Polenske e iodo.Durante las estaciones de invierno y verano se obtuvo grasa de ieciie de búfalo. Sebo de vaca (grasa del corazón) se adquirió del mercado local. El sebo de vaca se añadió a la grasa de leche de verano en las relaciones 5%, 10%, 15% y 50% w/w. Se aplicó la cronnatografia en capa fina para obtener la fracción de triglicéridos de cada nnuestra obtenida. La cromatografía gaseosa se usó para identificar el contenido… Show more

“…The high content of C 18 , C 18:1 and C 18:2 , with a lower content of total short chain fatty acids and total medium chain fatty acids are considered an evident that the butter of the samples 9 and 10 was adulterated with depot fat (Mervat and , Youness and Mervat, (1986), Youness, (1991), Ulberth, (1994 Nurrulhidayah, et.al.

“…The first methods developed were classical, such as determining the iodine number, Reichert-Meissl value (RMV) and Polenske value (PV). However, this has been proved to be insufficient, particularly at low concentration levels of adulterants [ 91 , 92 ]. So far, the instrumental methods used to detect adulteration of butter are based on detecting various milk fat components.…”
