Carotenoids pigments in crude and refined oils from Brazilian palm were analyzed. Beta-carotene was the principal fraction detected in all samples, varying from 142.6 micrograms/g to 314.25 micrograms/g in crude palm oils; from 132.55 micrograms/g to 612.16 micrograms/g in Brazilian palm kernels; and from 139.4 to 168.90 micrograms/g in refined palm oils. Alfa-carotene levels were 44.67 micrograms/g and 125.32 micrograms/g in the crude palm oil; 85.99 micrograms/g to 240.99 in palm kernel and 52.22 to 63.91 micrograms/g in refined palm oils. All-trans beta-carotene was the most important isomer; 9-cis and 13-cis alfa and beta-carotenes were also found. Vitamin A values were 2,065 and 10,255 RE in 100 g sample.
对巴西棕榈原油和精炼油中的类胡萝卜素色素进行了分析。β-胡萝卜素是所有样品中检测到的主要成分，在粗棕榈油中含量从142.6微克/克到314.25微克/克不等；在巴西棕榈仁中为132.55微克/克到612.16微克/克；在精炼棕榈油中为139.4微克/克到168.90微克/克。α-胡萝卜素在粗棕榈油中的含量为44.67微克/克和125.32微克/克；在棕榈仁中为85.99微克/克到240.99微克/克；在精炼棕榈油中为52.22微克/克到63.91微克/克。全反式β-胡萝卜素是最重要的异构体；还发现了9-顺式和13-顺式α-胡萝卜素和β-胡萝卜素。每100克样品中的维生素A值分别为2,065和10,255国际单位。
