[0015] Furthermore, the present invention provides diatomaceous earth-enriched rice polysaccharide feed prepared by any of the above preparation methods.

[0016] In the present invention, diatomaceous earth is a porous silicon mineral element with a high specific surface area. Especially in the state of nanoparticles, it has a very strong adsorption capacity. The first 0.5% of diatomaceous earth added can absorb 85% of the 18% rice polysaccharides produced into the pores and attach them, while maintaining a high degree of saccharifying agent activity.

[0017] The second dose of diatomaceous earth absorbs as much rice polysaccharide as it is produced, minimizing the inertia of sugar-producing microorganisms, encouraging more and faster sugar production, and achieving the conversion target of saccharification with high quality. Therefore, the second dose of rice polysaccharide can reach 27%, a quarter more than the first dose. At the same time, because diatomaceous earth can eliminate 99.98% of Staphylococcus aureus, 99.97% of Escherichia coli, and 99.33% of Candida albicans, it has a deodorization rate of 99.6% and an anti-allergic effect of 99.3%. Therefore, the polysaccharides produced and converted in rice will not become rancid or deteriorate within a certain time limit, and there will be no harmful bacteria, etc., ensuring the safety and stability of the polysaccharides. While significantly increasing the polysaccharide content in rice, the preparation method of the present invention can also increase the protein content in rice from the original only 8% to 17.6%.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The rice polysaccharide feed enriched with diatomaceous earth has seven main values: first, a high-quality, high-yield, and high-speed output polysaccharide feed resource has been developed; second, the entire process of developing the polysaccharide feed resource is eco-friendly and environmentally friendly, without any waste gas, waste residue, wastewater, or any other waste materials that pollute the environment; third, the polysaccharide feed resource is safe and nutritious; fourth, the polysaccharide feed resource can be fully replicated; fifth, all polysaccharide feed resources are renewable (except diatomaceous earth); sixth, the polysaccharide feed resource has significant economic benefits. Compared with the market value of rice, rice polysaccharides are generally five to six times more valuable than rice. However, since the process of enriching rice polysaccharides with diatomaceous earth is sophisticated and simple, and the cost is relatively low, it is a popular product welcomed by the market; and seventh, since the value of rice is increased, it has great strategic significance for maintaining food security.

[0021] Comparative Example 1 This comparative example provides a rice polysaccharide feed, the preparation method of which is different from that of the embodiment only in that: in the traditional Chinese medicine mixture, astragalus is replaced by an equal amount of American ginseng, licorice is replaced by an equal amount of stevia, cloves are replaced by an equal amount of orange peel, malt is replaced by an equal amount of barley sprout, momordica grosvenori is replaced by an equal amount of fig, codonopsis is replaced by an equal amount of ginseng, and hot polygonum is replaced by an equal amount of selfheal.

[0022] Comparative Example 2 This comparative example provides a rice polysaccharide feed, the preparation method of which is different from that of the embodiment only in that all diatomaceous earth is replaced with an equal amount of talc.

[0023] Comparative Example 3 This comparative example provides a rice polysaccharide feed, the preparation method of which is different from that of the embodiment only in that the addition of diatomaceous earth is omitted in all steps.

[0024] Comparative Example 4 This comparative example provides a rice polysaccharide feed, the preparation method of which is different from that of the embodiment only in that the addition of diatomaceous earth and the traditional Chinese medicine mixture is omitted in all steps.

[0025] Test example This test example commissioned the Wuhan Agricultural Products Testing Institute of Hunan University of Science and Technology to test the polysaccharide content in the feeds prepared in the above examples and comparative examples. The test results of polysaccharides in the feeds are shown in Table 1.

[0026] Table 1

[0027] As can be seen from Table 1, the feed in the embodiment has the highest sugar content. The function and medicinal properties of the Chinese medicine composition used in Comparative Example 1 are similar, and even American ginseng and ginseng are functionally enhanced, but the sugar production is unexpectedly reduced. Comparative Example 2 also significantly reduces sugar production after replacing diatomaceous earth with talc. This shows that the Chinese medicine composition with a specific formula used in the present invention, combined with the diatomaceous earth carrier, produces a synergistic effect of enhancing sugar production, significantly increasing the polysaccharide content in the feed, and can maximize sugar production benefits.
