Analysis of mesocarp and kernel oils from the American oil palm and F₁ hybrids with the West African oil palm

Abstract

The mesocarp oil of the American oil palm is more unsaturated than that of the West African oil palm. Mesocarp oils obtained from F1 hybrids of these two oil palms exhibit an intermediate degree of unsaturation. Hybrid kernel oils are similar in composition to that of their West African oil palm parent, whereas kernel oils from the American oil palm are considerably more unsaturated and exhibit a unique fatty acid composition among seed fats of the Palmae family.

Quantitative trait loci (QTLs) analysis of palm oil fatty acid composition in an interspecific pseudo-backcross from Elaeis oleifera (H.B.K.) Cortés and oil palm (Elaeis guineensis Jacq.)

“…An interspecific cross E. oleifera × E. guineensis shows mean values for fatty acid proportions which are intermediate between the mean values of its E. oleifera and E. guineensis parents (Hardon 1969;Macfarlane et al 1975;Meunier and Boutin 1975;Opute and Obasola 1979;Tan et al 1985). This is in accordance with the codominance theory for genes involved in palm oil biosynthesis and their alleles inherited from each Elaeis parent (Hardon 1969;Ong et al 1981).…”

Chemical Characteristics and Nutritional Properties of Hybrid Palm Oils

“…The free fatty acid (FFA) content ranges between 0.35 (as g/100 g oil, determined by GC areas) and 2.91 (as palmitic acid %, determined by titration) [31][32][33]. Higher FFA contents (9.7-36.7%, as palmitic acid) were ascribed to improper handling of raw material [34]. In fact, mesocarp lipase (triacylglycerol acyl hydrolase, EC 3.1.1.3) has been associated with the membranes of oleosomes (lipid bodies) and is activated when any kind of damage occurs to fruits, during harvest, transportation, and storage.…”

Genetic Variation and Heritability Estimates for Bunch Yield, Bunch Components and Vegetative Traits in Oil Palm Interspecific Hybrids

“…E. guineensis is widely accepted to originate from Africa. Lately, attention is being paid to E. oleifera-the South and Central American species, for some of its potentially useful attributes, such as slower height increment [2][3][4][5], higher oil unsaturation [6,7] and resistance to certain diseases [8][9][10]. E. oleifera hybridizes readily with E. guineensis to produce interspecific hybrids (O  P), and it has been advocated as a promising source of new genetic variation in the oil palm [11,12].…”
