To all evhom it may concern:

Be it known that I, GARLETON ELLIS, a

' citizen of th {United States, and a resident of Montcla l .';in the county of Essex and Stateof New' 'Jersey, have invented certain new and useful Improvements in Edible Oil Products, of which the following is a speci-- fication, I a

This invention relates to a process of'making an edible oil product especially a.c0mpo sition suited for'use as .a' vegetable lard and' relates in particular to the use of hydroenated o ls and the like, especially in conunction with cocoanut oil 'or fat with or without hydrogenation treatment, and also relates to a process ofmaking a composition comprising hydrogenated cotton seed oil or soya bean and cocoanut oil and the like and to the composition derived by such process; all as more fully hereinafter described and claimed.

By treatment of cotton seed oil with hydro n in the presence ofa catalyzer, 'such as iiely divided nickel, .a solid product is secured which is practically free from odor,

and which may be-blended or may be incorporated with oils or fats such as cocoanut o l, to produce a'vegetable lard part1cularly well adapted to culinary operations.

Such a product, however, is not fullysatisfactory in appearance for edible purposes,

' and by' the present invention special treatment is provided which affords a product of the proper appearance.

To illustrate the pr Int invention, the

. following formula and method of treatment will be given: Ninety parts. of cotton seed oil are mixed: with 'ten parts of cocoanut oil and the mixture subjected to. the. action of hydrogen at a temperature of about .ito 160 "C. in thepresenee of. finely divided 'nickel,whereby a substantial proportion of the unsaturated material is converted into saturated] material. The

iodin number of the composition is thereby reduced and a solid [composition forms which may be subjected to the operation of aeration. The aeration treatment may;com-

prise beating the h dregenated composition with rapidly v revo ving paddles or: blades until a. sufiicient quantity of a r is incorporated in the productyin a finely vesiculated or well distributed condition, to produce a material of the desired light colored appearance. Ordinarily, I prefer to"incorporate severalper cent. by volume of 'airin' this manner, 5 to 10% by volume being a suitable amount. 1

I The proportion of cocoanut oil which may be incorporated, is preferably about 10% although twice this amount may be used i desired. "The. amount should not however, under ordinary conditions, exceed 30%, ui1-' .les's care be taken to completely hydrogenate all unsaturated material in the'cocoanu't 011.

To be sure, cocoanut oil has an iodin value of only 7 to :10 which is indicative of the --small proportion of unsaturated bodies present. But in spite of this, in order to secure tions than 30% or thereabout are-incorporalted with the hydrogenated cotton seed o1 1 In a similar manner, cocoanut oil may be incorporated in aerated mixture with hydrogenated corn, soya bean or peanut "011, or similar vegetable oils, itibeing desirable to materially reduce the iodin number by hydrogenation, in the case of these oils, in the event cocoanut oil'to the extent of 20% or' 30% is to be incorporated. In any case,

hydrogenation shouldpreferably be carried to the point where a soft body of the consistency of ordinary lard is produced.

The advantages of such a product over ordinary lard "are severaL- One is that owing to thehigh-evaporation pointof the more volatile components of the hydrogen- .ated. product as above set forth, ordinarily there is less smoke and fume caused when heating these oils ,in culinary operations.

Furthermore, owing to the higher tempera-,

ture which may be reached with compositions of this character, better efiects are se cured, especially infrying operations.

. While it is' possible to aerate ordinary fat, by treating is difficult. to produce a product-which will keep for a lontgl eorporated wi period when intimately inair in this manner, but by in; the manner described, 1t
