[0001] The invention relates to the technical field of food processing, in particular to a coix seed extract food and a preparation method thereof. Background Art

[0002] Coix seeds, as a common food and medicine material, have a variety of pharmacological activities, such as protecting the liver, whitening, and strengthening the spleen. Modern research shows that the active ingredients in coix seeds, such as coix seed polysaccharides and coix seed oil, have significant pharmacological effects. However, the existing coix seed extract foods often have problems such as solvent residues, low purity of active ingredients, and single efficacy during the preparation process. Therefore, it is particularly important to develop an efficient, safe and multi-functional coix seed extract food. Summary of the invention

[0003] The purpose of the present invention is to provide a coix seed extract food and a preparation method thereof, which can not only improve the purity of the coix seed extract, but also effectively combine other natural extracts to enhance their comprehensive efficacy, and is suitable for a variety of product forms.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a coix seed extract food and a preparation method thereof, characterized in that the food is prepared from coix seed extract, selectively added synergistic excipients and additives in proportion to form tablets or powder for preparation or capsules, and the compounding ratio is: 35 to 80 parts of the coix seed extract, 0 to 45 parts of the synergistic excipients, and 5 to 25 parts of the additives.

[0005] Furthermore, the synergistic excipient is a natural extract that provides corresponding synergistic effects based on the pharmacological activities of coix seed, such as protecting the liver, strengthening the spleen and whitening. It can be one or more combinations of natural extracts. The selective addition is to choose which synergistic excipient to add or not to add the synergistic excipient.

[0006] Further, in some possible implementations, the liver-protecting synergistic excipients include, but are not limited to, extracts of one or more combinations of wolfberry, white peony root, lotus seed, mung bean, and red dates; In some possible implementations, the spleen-strengthening synergistic excipients include, but are not limited to, extracts of one or more combinations of yam, lily, red bean, tuckahoe, Euryale ferox, dendrobium, and polygonatum; In some possible implementations, the auxiliary materials with synergistic whitening effects include, but are not limited to, extracts of one or more combinations of lily, mung bean, lotus seed, red date, licorice, and lemon.

[0007] The additive is one or more combinations of betaine, starch, maltodextrin, vitamins and flavoring agents, wherein the betaine is a natural extract. When betaine is combined with pepsin, it can effectively promote the decomposition of protein, improve the bioavailability of nutrients, and make food easier to digest and absorb.

[0008] Furthermore, the flavoring agent is one or more combinations of plant extracts, and the plant extracts are preferably fruit and vegetable extracts such as stevioside, mogroside, and beetroot extract.
