Abstract:
The present invention relates to an improved method of recovering rubber from skim natural rubber latex. The method comprises pre-treating the skim latex, concentrating the skim latex using one membrane module or two membrane modules in series with addition of potassium hydroxide or a solution containing ammonium laurate and potassium hydroxide, optionally treating the concentrated skim latex with a tetramethylthiuramdisulphide (TMTD) and zinc oxide (ZnO) dispersion, blending the concentrated latex with fresh field latex, centrifuging the blend to obtain a latex concentrate. The latex concentrate is further blended with a fresh latex concentrate and treated with ammonia to obtain the final latex concentrate.
Abstract:
The present invention relates to an external preparation for skin containing pollen extract of oil palm of the genus Elaeis guineensis in an amount between 0.05% and 1.00% by weight, based on the total weight of the external preparation, for whitening skin.
Abstract:
The present invention relates to a process for refining glyceride oil by size exclusion chromatography to obtain a triglyceride enriched fraction. The process comprises passing a glyceride oil through a size exclusion column packed with porous particles having a mass weighted mean particle size of 20 to 1,000 pm and an average pore size of 10 to 150A without using any solvent and collecting an eluate fraction enriched in triglyceride. The process may further comprise passing a solvent through the size exclusion column after the eluate fraction enriched in triglyceride is collected to obtain a partial glyceride enriched fraction. The process can suitably be used to produce triglyceride enriched fraction having a triglyceride content that is close to 100%.
Abstract:
Methods are provided for obtaining a high-yielding oil palm plant, comprising determining the level of a metabolite in mesocarp tissue of a fruit of a parental oil palm plant 11 to 23 weeks after pollination thereof, determining whether there is a difference between this level and the level of the metabolite in mesocarp tissue of a fruit of a reference oil palm plant, also 11 to 23 weeks after pollination thereof, wherein the difference is that the level of the metabolite is at least 15% higher, or at least 5% lower, for the parental oil palm plant relative to the reference oil palm plant, and selecting progeny of the parental oil palm plant based on the difference to obtain the high-yielding oil palm plant. Also provided are methods for predicting oil yield of a test oil palm plant and kits for obtaining a high-yielding oil palm plant.
Abstract:
The present invention provides a method for fractionating an oil composition containing at least 80% by weight of diacylglycerol into a solid fraction and a liquid fraction, which heats the oil composition to an elevated temperature, cools the oil composition to deposit crystals at a cooling rate of 0.05°C/min to 3.00°C/min to an end-temperature in the range of 30°C to 50°C while stirring to obtain crystal slurry, and fractionating the crystal slurry into a solid fraction and a liquid fraction.
Abstract:
The present invention relates to a process of manufacturing palm oil fractions containing virtually no 3-monochloropropanediol fatty acid esters (3-MCPD-esters). More particularly, the present invention provides a process of manufacturing a palm oil fraction that contains virtually no 3-MCPD-esters, said process comprising: ° fractionating a crude palm oil having a free fatty acid content of less than 1.5% and a diglyceride content of less than 5.5 wt.% to produce at least one crude palm oil fraction, said crude palm oil fraction being selected from crude palm olein having an iodine value of at least 55 and crude palm stearin having an iodine value of less than 48; and ° deodorising the crude palm oil fraction to produce a deodorised palm oil fraction having an 3-MCPD-ester content of less than 1 ppm. The invention further provides a method of preparing a food product, said method comprising incorporating into said food product 3-99 wt.% of a palm oil fraction obtained by the aforementioned process.
Abstract:
Methods for predicting palm oil yield of a test oil palm plant are disclosed. The methods comprise determining, from a sample of a test oil palm plant of a population, at least a first SNP genotype, corresponding to a first SNP marker, located in a first QTL for a high-oil- production trait and associated, after stratification and kinship correction, with the high-oil- production trait with a genome-wide -log10(p-value) of at least 4.0 in the population or having a linkage disequilibrium r2 value of at least 0.2 with respect to a first other SNP marker linked thereto and associated, after stratification and kinship correction, with the high-oil-production trait with a genome-wide -log10(p-value) of at least 4.0 in the population. The methods also comprise comparing the first SNP genotype to a corresponding first reference SNP genotype and predicting palm oil yield of the test plant based on extent of matching of the SNP genotypes.
Abstract:
The present invention provide a continuous dry fractionation process comprising the successive step of: (a) providing a liquid glyceride oil having a temperature that is at least 5°C higher than the solidification onset point (SOP) of the glyceride oil, the SOP of the glyceride oil being the minimum temperature at which the glyceride oil has a N-value of 0%; (b) precooling the liquid glyceride oil at a cooling rate of at least 1 °C/min by passing the glyceride oil through a heat exchanger to reduce the temperature of the liquid glyceride oil with at least 5°C to a temperature that is not lower than 10°C below the SOP and not higher than 5°C above the SOP; (c) homogenizing the precooled glyceride oil to produce a prenucleated glyceride oil by passing the precooled glyceride oil through a homogenizer in which the temperature of the glyceride oil is kept a temperature within 1 °C of the prenucleation temperature T p for at least 0.5 hour, said T p being 0.5-10°C below the SOP; (d) crystallizing the prenucleated glyceride oil to produce a crystallized glyceride oil containing separable fat crystals by passing the prenucleated glyeride oil through one or more crystallizers to reduce the temperature of the prenucleated glyceride oil with at least 10°C to a crystallization temperature T c and keeping the glyceride oil at a temperature within 1 °C of T c for at least 1 hour; and (e) removing separable fat crystals from the crystallized glyceride oil and recovering an olein fraction of the glyceride oil. This continuous fractionation process enables the manufacture of a high quality olein fraction in high yield and in a relatively short period of time.

Abstract:
This invention relates to a method for identifying a Ganoderma -infected palm tree. The method comprises isolating protein from a sample derived from leaves of a palm tree; determining protein profile of the sample by subjecting the proteins from the sample to gel electrophoresis on a 2-dimensional gel; and comparing the protein profile of the sample to a protein profile obtainable from a normal non- Ganoderma - infected palm tree, wherein a difference in the protein profile of the sample as compared to the protein profile of the normal non- Ganoderma -infected palm tree indicates that the palm tree is infected with Ganoderma disease.
