Abstract:
The present invention relates to a method for isolating shikimic acid from oil palm waste using resin adsorption and hydrolysis techniques. The method comprises the steps of subjecting an oil palm waste material to resin adsorption to obtain an adsorbent containing caffeoylshikimic acid isomers, recovering caffeoylshikimic acid isomers in a single fraction, followed by subjecting the single fraction to hydrolysis to obtain shikimic acid and purifying the shikimic acid. The method in accordance with the invention provides good recovery of shikimic acid and enables the shikimic acid to be purified using simple purification method.

Abstract:
This invention relates to a process for producing diacylglycerol-enriched fat or oil, which includes, charging a reaction chamber with a fat or oil and an immobilized lipase preparation to obtain a reaction mixture; adding glycerol to the reaction mixture at a rate of not more than 40 parts by weight of glycerol per 100 parts by weight of the immobilized lipase preparation per hour; removing water content in the reaction mixture; and separating unreacted materials and by-products from the reaction mixture to obtain the diacylglycerol-enriched fat or oil.
Abstract:
The present invention relates to an edible product that is composed of a plurality of discrete fat pieces that are in direct contact with each other, such as fat flakes, fat powders or fat granulates. More particularly, the present invention provides an edible product that is composed of a plurality of discrete fat pieces that are in direct contact with each other, each fat piece comprising: 15-80 wt.% of a solid continuous fat phase having a solid fat content at 25 ºC (N 2 ) of at least 5 wt.%; 20-85 wt.% of an oil encapsulate that is homogeneously dispersed throughout the continuous fat phase, said oil encapsulate containing 40-95 wt.% of liquid oil and 5-60 wt.% of an encapsulation matrix that envelops the liquid oil; and 0-50 wt.% of a dispersed aqueous phase; wherein the edible product contains at least 15% of liquid oil by weight of the continuous fat phase and wherein the continuous fat phase, the oil encapsulate and the optional dispersed aqueous phase together represent at least 90 wt.% of the edible product. The fat pieces in the edible fat product according to the invention, despite containing a substantial amount of liquid oil, do not clump together and can suitably be used in a variety of product applications, such as bakery products, soups, sauces, creamers and reconstitutable drinks.
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.

The present invention provides a vegetable fat blend that can suitably be used to replace milk fat in processed food products or to prepare imitation dairy products. The vegetable fat blend according to the present invention is characterised in that it contains: 0.5 - 15 of red palm oil; 15 - 75 wt.% of a highly unsaturated oil selected from the group consisting of sunflower oil, soybean oil, ra peseed oil, cottonseed oil, safflower oil, marine oil, corn oil, olive oil, linseed oil and combinations thereof; and 25 - 60 wt.% of a structuring fat selected from the group consisting of palm oil, palm oil fractions, lauric fat, lauric fat fractions, full y hydrogenated vegetable oil, and combinations thereof; wherein the red palm oil contains at least 200 ppm of carotenoids and 200 ppm of tocotrienols.
Abstract:
The invention provides a process of treating crude vegetable oil, said process comprising the steps of: • providing crude vegetable oil having a FFA content of at least 0.5%; • providing biologically treated aqueous discharge from an oil milling process, said biologically treated aqueous discharge having a water content of at least 80 wt.% and a total alkalinity of at least 1,000 mg CaC0 3 per litre; • mixing the crude vegetable oil with the biologically treated aqueous discharge in a weight ratio of crude vegetable oil to biologically treated aqueous discharge in the range of 1 :10 to 10: 1 to produce a neutralization mixture; and • separating the neutralization mixture into treated vegetable oil and soap-containing aqueous liquor. This process offers the advantage that it enables the preparation of a crude vegetable oil with reduced FFA content without using chemicals, such as caustic soda. Furthermore, the process can be used to improve the Deterioration of Bleachability Index (DOBI) of crude vegetable oil. Finally, the process also reduces the amount of oil mill effluent.

Abstract:
The invention relates to a process of refining refined palm fruit oil products that yields a refined oil product having an exceptionally low content of 3-MCPD fatty acid esters. More particularly, the present invention provides a process of refining a crude palm fruit oil product, said process comprising the successive steps of: a) removing phospholipids and/or free fatty acids from a crude palm fruit oil product by subjecting the oil product to a pretreatment, thereby producing a pretreated palm fruit oil product with a reduced phospholipid content and/or a reduced free fatty acid content; b) simultaneously or sequentially contacting the pretreated palm fruit oil product with bleaching earth and a porous amorphous silicate to produce a bleached palm fruit oil product, said porous silicate material having a surface area of at least 10 m 2 /g; and c) deodorizing the bleached palm fruit oil product to produce a refined palm fruit oil product. The invention also relates to a refined palm fruit oil product obtained by the aforementioned process and to an edible product containing 1-80 wt.% of such refined palm fruit oil product.
