Abstract
A METHOD FOR PREPARING HARD BUTTERS FROM PALM OIL
ABSTRACT OF THE DISCLOSURE
Hard butters, which are suitable replacements for cacao butter and which may be used for confectionary products without the occurrence of blooming, are obtained by hydrogenating a frac-tionated soft palm oil having an iodine value of at least 55 with a conventional hydrogenation catalyst in the presence of methionine, whereby at least 40% of the glycerides are trans-isomers (calcula-ted as trielaidine) and, optionally separating the middle-fraction of the hydrogenated product.
ABSTRACT OF THE DISCLOSURE
Hard butters, which are suitable replacements for cacao butter and which may be used for confectionary products without the occurrence of blooming, are obtained by hydrogenating a frac-tionated soft palm oil having an iodine value of at least 55 with a conventional hydrogenation catalyst in the presence of methionine, whereby at least 40% of the glycerides are trans-isomers (calcula-ted as trielaidine) and, optionally separating the middle-fraction of the hydrogenated product.
Claims (12)
1. A process for preparing a hard butter from palm oil said method comprising hydrogenating a soft palm oil fraction having an iodine value of at least 55 with a conventional hydrogenation catalyst in the presence of a catalytically effective amount of a methionine to thereby form a hardened product containing at least 40% of trans-isomers and in the case where the iodine value of the starting soft palm oil is less than 60, subjecting the hardened product to a further fractionation to remove high-melting glycerides therefrom, the methionine being selected from the group consisting of l-methionine, d-methionine, dl-methionine, methionine sulfoxide, methyl sulfonium methionine, .beta.-methionine and functional derivatives thereof, including salts, esters, ethers and N-acyl derivatives thereof.
2. A process according to claim 1, wherein the further fractionation is a solvent fractionation.
3. A process according to claim 2, wherein the solvent fractionation is effected with methyl ethyl ketone, acetone, hexane, petroleum ether or ethyl acetate.
4. A process according to claim 2 wherein the solvent fractionation is effected in two stages; a first stage at 15-25°C. to precipitate out undesirable high-melting glycerides and a second stage at 5-10°C. to precipitate out the desired hard butter.
5. A process according to claim 1, wherein the iodine value of the soft palm oil fraction is at least 60, in which case, the further fractionation of the hardened product is unnecessary.
6. A process according to claim 1, wherein the hydrogena-tion catalyst is an activated nickel catalyst.
7. A process according to claim 6, wherein the activiated nickel catalyst comprises 18% nickel embedded in diatom-aceous earth.
8. A process according to claim 1, wherein the amount of catalyst and methionine respectively, are 0.1-3.0% and 0.003-0.3% by weight based on the weight of the soft palm oil fraction.
9. A process according to claim 1, wherein the hydrogena-tion is effected at 160° to 220°C. and a hydrogen pressure (gauge) of 1 to 10 kg./cm2.
10. A process according to claim 1, wherein the soft palm oil fraction has an iodine value ranging from at least 55 to about 75.
11. A process according to claim 1, wherein the soft palm oil fraction contains up to about 20% by weight of a highly unsaturated oil.
12. A process according to claim 11, wherein the highly unsaturated oil is rape seed oil, rice bran oil, cotton seed oil or soybean oil.
