Fractionation which separates the olein (liquid) and stearin (solid) fractions of oil is used to modify the physicochemical properties of fats in order to extend its applications. Studies showed that the properties of fractionated end products can be affected by fractionation processing conditions. In the present study, dry fractionation of palm-based diacylglycerol (PDAG) was performed at diff...

BACKGROUND Waxes are esters of long-chain fatty acids and long-chain alcohols. Their principal natural sources are animals (sperm whale oil) and vegetables (jojoba) which are expensive and not easily available. Wax esters synthesized by enzymatic transesterification, using palm stearin as raw material, can be considered as an alternative to natural ones. RESULTS Palm stearin is a solid fracti...

Abstract The study examined the effect of stearin and paraffin adulteration wax foundation on brood survival. In combs formed a stearin-adulterated (10, 30, 50% stearin, which means: 3.9, 11.7, 19.5% stearic acid, respectively), survival decreased statistically significantly ( p ? 0.001) compared to rates noted pure beeswax foundation. appearance resembled so-called scattered although queens ov...

Blending helps extend the range of application of oils and fats. This is because most natural oils and fats have limited applications in their original form. Natural oils and fats may need to be modified to suit a particular product formulation. Blending is the simplest method used to modify oils and fats. From the palm fruits, a wide range of products can be derived including palm oil, palm ol...

The aim of this work was to produce lipases by solid-state fermentation (SSF) using, as substrate, agroindustrial residue supplemented with by-products from corn oil refining process or olive oil. For a group of ten fungi strains selected in the first steps, the lipase activity obtained by SSF varied from 7.7 to 58.6 U/g of dry substrate (gds). Among the evaluated strains, the Aspergillus niger...

This work described study protocols on the production of Palm-Based Standard Reference Materials for iodine value and slip melting point. Thirty-three laboratories collaborated in the inter-laboratory proficiency tests for characterization of iodine value, while thirty-two laboratories for characterization of slip melting point. The iodine value and slip melting point of palm oil, palm olein an...

Effects of different dietary fats on plasma, hepatic and biliary lipids were determined in male golden Syrian hamsters (Mesocricetus auratus) fed on purified diets for 7 weeks. Diets were made by blending different fats containing characteristic fatty acids: butter (14:0 + 16:0), palm stearin (16:0), coconut oil (12:0 + 14:0), rapeseed oil (18:1), olive oil (18:1) and sunflowerseed oil (18:2). ...

Abstract Production of fresh pineapple fruit is dominated by the MD2 clone, while GP3 clone used as canned fruit. To be promoted fruit, has some defects, namely a less sweet taste and sensitivity to internal browning (IB) disorders. The clones need coatings, two might get responded differently. This study aimed effects chitosan-based coating mixed with palm stearin Aloe vera gel on qualities cl...

A nutritional evaluation of refined, bleached and deodorised (RBD) palm oil and its fractionation products, RBD palm olein and RBD palm stearin in terms of their digestibility, rate of absorption and food efficiency in rats, shows that RBD palm olein is a better oil by these criteria than RBD palm stearin and the unfractionated RBD palm oil. Nevertheless, the nutritional indices reported for RB...
