Abstract
Abstract Hard butters which are particularly suitable for use as cocoa butter substitutes and which can be used in the manufacture of confectioneries without tempering are prepared by hydrogenating a fat or oil having an iodine value within the range of 60 to 78 and a total content of linoleic and linolenic acids of less than 17 weight percent with a nickel catalyst containing 6 to 21 parts by weight sulfur per 100 parts nickel.

Claim 5
Dependent Claim
40 words
A process according to claim 1 wherein said fat or oil includes combined C16 fatty acids in an amount within the range of 25 to 50 weight %, based on the total combined fatty acids or said oil or fat.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
33 words
A process according to claim 4 wherein said fat or oil is prepared by an interesterification between palm oil or a palm oil fraction and soy bean oil or hydrogenated soy bean oil.
Claim 8
Dependent Claim
20 words
