Abstract

The present invention relates to a method of preparing high-strength coated whole cottonseed for livestock feed, wherein the germination ability of whole cottonseed is removed using high-temperature and high-pressure steam, and the surface of whole cottonseed is coated with gelatinized starch with high viscosity, which is prepared by gelatinizing starch in a preparation process. According the method of the present invention, since the germination ability of whole cottonseed is removed, release of foreign genes into the domestic environment, which may occur when using whole cottonseed for livestock feed, may be fundamentally prevented, and thus the method of the present invention may contribute to protection of domestic plant genetic resources. In addition, the use of gelatinized starch with increased viscosity, which is prepared by gelatinizing starch in a preparation process, may dramatically increase the selection range of coating agents. Furthermore, since coated whole cottonseed can be prepared without a drying process, which consumes a large amount of energy, the method of the present invention may increase economic effect by resolving economic problems, such as high production costs, encountered when preparing whole cottonseed for livestock feed.

Claims

1. A method for manufacturing high-strength coated whole cottonseed for livestock feed without a drying process, comprising:

a step of removing lint adhered to whole cottonseed using a lint remover; and

a step of disfunctioning a sprouting function of the whole cottonseed and improving a viscosity of a coating agent in a preparation process by gelatinizing the coating agent using steam.

2. The method according to claim 1, characterized in that the method comprises (1) a first step of removing lint from whole cottonseed;

(2) a second step of preparing a mixture by adding a coating agent and purified water to whole cottonseed, followed by mixing;

(3) a third step of disfunctioning a sprouting function of whole cottonseed while agitating the mixture in order to obtain coating agent-bound whole cottonseed by gelatinizing the mixed coating agent by spraying high-temperature and high-pressure steam into the mixture; and

(4) a fourth step of preparing coated whole cottonseed as a final product by cooling the coating agent-bound whole cottonseed without a drying process.

3. The method according to claim 2, characterized in that, in the first step, the whole cottonseed is a whole cottonseed imported from Australia, America, China, India, Pakistan, Brazil, Turkey, Uzbekistan, Greece, and Vietnam or domestic whole cottonseed.

4. The method according to claim 2, characterized in that, in the first step, the lint is finally removed to an amount of 1 to 10% by weight based on a weight of the whole cottonseed.

5. The method according to claim 2, characterized in that, in the second step, the coating agent is one or more selected from the group consisting of starch such as cornstarch, tapioca starch, wheat starch, rice starch, potato starch;

saccharides, condensed molasses fermentation solubles (CMS), molasses;

cereals such as corn flour, tapioca flour, wheat flour, rice flour; and

cellulose; and

mixtures thereof.

6. The method according to claim 2, characterized in that the process of adding purified water of the second step and the process of spraying high-temperature and high-pressure steam of the third step are performed once or repeatedly.

7. The method according to claim 2, characterized in that, in the second step, the purified water is added in an amount of 1 to 20% by weight based on a weight of the whole cottonseed, followed by mixing, so as to increase coating strength.

8. The method according to claim 2, characterized in that, in the second step, the coating agent is added in an amount of 0.01 to 30% by weight based on a weight of the whole cottonseed.

9. The method according to claim 2, characterized in that, in the second step, as a manner of coating, the coating agent is equally aliquoted into two to five portions in an amount of 1/100 to 1/5 (w/w) based on a total addition amount of the coating agent, and then continuously added while stirring.

10. The method according to claim 2, characterized in that, in the third step, a temperature of the steam is 80 to 140°

C. and the steam is sprayed by a pressure of 1 to 15 kg/cm².

11. The method according to claim 2, wherein, in the third step, the process of spraying the high-temperature and high-pressure steam is performed for 30 seconds to 10 minutes.

12. The method according to claim 2, characterized in that, in the third step, a final gelatinization degree of the gelatinized coating agent is 60 to 98%.

13. The method according to claim 2, characterized in that, in the third step, furthermore a palatizing addictive selected from the group consisting of molasses, salt, monosodium glutamate (MSG), MSG by-products, saccharides (sugar, glucose, sodium saccharin), flavoring agents (vanilla flavor, strawberry flavor), volatile fatty acid, and condensed molasses fermentation solubles (CMS) and mixtures thereof is added for improving a palatability of the final coated product.

14. The method according to claim 2, characterized in that, in the fourth step, a moisture content of the final coated product is adjusted to 11 to 15%.

15. The method according to claim 2, characterized in that, in the fourth step, the cooling is performed for 1 to 60 minutes.

16. The method according to claim 2, characterized in that, in the fourth step, a moisture content of the final coated product is properly maintained without a drying process by adjusting an addition amount of the purified water in the second step, and an amount of the sprayed steam and an amount of moisture consumed during gelatinization of starch in the third step.

17. Coated whole cottonseed prepared by the method according to claim 1.
