Partial neutralization of free fatty acid mixtures with magnesium, livestock feed compositions including them, and methods of making same
The present invention includes a nutritional supplement composition that may be used for livestock and the like, as well as to a livestock feed mixture containing same. Also included are methods of preparing the nutritional supplement composition, the livestock feed mixture, as well as methods of providing nutrition to livestock and the like. The livestock feed composition comprises: (a) a solid particulate livestock feed material and (b) a solidified particulate mixture of (i) free fatty acid and (ii) a magnesium salt of a fatty acid, the magnesium salt of a fatty acid being present in an amount in the range of from about 25% to about 55% of the amount of the free fatty acid based upon the theoretical requirement to accomplish the total neutralization of all of fatty acid present.
1. A method of producing a partially magnesium/neutralized free fatty acid mixture, the method comprising the steps:
a. preparing a mixture of:
i. an amount of a free fatty acid; and
ii. an amount of a magnesium-containing material comprising a magnesium-containing basic compound adapted to form a magnesium salt of said fatty acid, said magnesium-containing material being present in an amount in the range of from about 25% to about 55% of the amount of a free fatty acid based upon the theoretical requirement to accomplish the total neutralization of all of fatty acid present; and
b. maintaining said mixture at sufficient temperature and for sufficient amount of time so as to form a mixture of free fatty acid and partially magnesium/neutralized free fatty acid having an onset melt point of from 170° F. to 200° F.
2. A method according to claim 1 wherein said free fatty acid is selected from said group consisting of tallow and non-tallow fatty acids, and mixtures thereof.
3. A method according to claim 1 wherein said free fatty acid is selected from the group consisting of non-tallow fatty acids selected from the group consisting of fatty acids from palm oil, soy oil, fish oil, linseed oil and flax oil, and mixtures thereof.
4. A method according to claim 1 wherein said mixture is maintained at a temperature in the range of from about 255 degrees to about 300 degrees Fahrenheit during step (b).
5. A method according to claim 1 wherein said mixture is additionally subject to a prilling process.
6. A method according to claim 1 wherein said mixture is additionally subject to a flaking process.
7. A composition comprising a solidified particulate mixture of free fatty acid and a magnesium salt of a fatty acid, said magnesium salt of a fatty acid being present in a molar ratio amount in the range of from about 25% to about 55% of the amount of said free fatty acid based upon the theoretical requirement to accomplish the total neutralization of all of fatty acid present and having an onset melt point of from 170° F. to 200° F.
8. A composition according to claim 7 , wherein said free fatty acid comprises tallow fatty acid, and said magnesium salt of a fatty acid comprises a magnesium salt of a tallow fatty acid.
9. A composition according to claim 7 wherein said free fatty acid is selected from the group consisting of tallow and non-tallow fatty acids, and mixtures thereof.
10. A composition according to claim 7 wherein said free fatty acid is selected from the group consisting of non-tallow fatty acids selected from the group consisting of fatty acids from palm oil, soy oil, fish oil, linseed oil and flax oil, and mixtures thereof.
11. A composition according to claim 7 , wherein said mixture is a solid having an onset melt point of up to 170 degrees Fahrenheit and a hardness of at least about 15 shore A units at 170 degrees Fahrenheit.
12. A composition according to claim 7 , wherein said mixture comprises magnesium equivalent to magnesium oxide present in an amount of from about 3.5% to about 5.5%, most preferably between about 4% and about 5%.
13. A livestock feed composition comprising (a) a solid particulate livestock feed material and (b) a solid particulate mixture of (i) free fatty acid and (ii) a magnesium salt of a fatty acid, said magnesium salt of a fatty acid being present in an amount in the range of from about 25% to about 55% of the amount of said free fatty acid based upon the theoretical requirement to accomplish the total neutralization of all of fatty acid present, and wherein said solid particulate mixture is a mixture of free fatty acid and partially magnesium/neutralized free fatty acid with an onset melt point of from 170° F. to 200° F.
14. A livestock feed composition according to claim 13 , wherein said free fatty acid comprises tallow fatty acid, and said magnesium salt of a fatty acid comprises a magnesium salt of a tallow fatty acid.
15. A livestock feed composition according to claim 13 wherein said free fatty acid is selected from said group consisting of tallow and non-tallow fatty acids, and mixtures thereof.
16. A livestock feed composition according to claim 13 wherein said free fatty acid is selected from the group consisting of non-tallow fatty acids selected from the group consisting of fatty acids from palm oil, soy oil, fish oil, linseed oil and flax oil, and mixtures thereof.
