[0002] Modulated milk is a liquid product made from no less than 80% raw cow (sheep) milk or reconstituted milk as the main raw material, with other raw materials, food additives or nutritional fortifiers added, and appropriate sterilization or sterilization processes. For example, in order to maintain the stability of the modulated milk product, stabilizers such as monoglyceride and diglyceride fatty acid esters, sucrose esters, and microcrystalline cellulose are usually added during the production process of the modulated milk; for another example, in order to prepare coagulated modulated milk products, gelatin, xanthan gum, carrageenan, guar gum and other thickeners are mostly added to maintain the coagulation characteristics of the product. Although there is no food safety problem when using food additives within the scope prescribed by national laws and regulations, it does not meet consumers' pursuit of healthy and natural food, and is contrary to the original intention of nutritional and functional fortification of modulated milk. Summary of the invention

[0008] Preferably, the particle size of the cooked oatmeal coarse powder is 8 to 20 meshes; and the particle size of the finely divided cooked oatmeal is 25 to 100 meshes.
[0009] Preferably, it also includes a sweetener;
[0010] Taking the mass of the coagulated modulated milk as 100%, the coagulated modulated milk comprises 83.5% to 95.6% of raw milk, 3.5% to 6.8% of cooked oatmeal powder, 2.8% to 4.6% of cooked oatmeal powder, 0.5% to 1.8% of chia seeds and 1.5004 to 3.001% of sweetener.
[0011] Preferably, the mass percentage of dietary fiber in the cooked oatmeal in the cooked oatmeal coarse powder or cooked oatmeal fine powder is not less than 12.6%, and the mass percentage of β-glucan is not less than 4%;
[0012] The sweeteners include sucralose and / or erythritol.
[0013] The present invention provides a method for preparing the dietary fiber-rich coagulated modulated milk, comprising the following steps:
[0014] The pretreated raw milk, the coarse cooked oat flakes and the fine cooked oat flakes are mixed and heated to obtain a first material;
[0015] Mixing the first material and chia seeds again to obtain a second material;
[0016] The second material is sterilized to obtain a coagulated modulated milk.
[0017] Preferably, the method for pre-treating raw milk comprises removing impurities from the raw milk, preheating the milk to 50-55° C., and sequentially degassing, homogenizing and pasteurizing the raw milk;
[0018] The homogenization temperature is 70-75° C.; the homogenization pressure is 240-260 bar.

At the same time, because cooked oatmeal contains a large amount of dietary fiber, the prepared coagulated modulated milk has a higher sensory score and promotes intestinal peristalsis, helps prevent constipation, and maintains intestinal microbial balance, thereby supporting the health of the overall digestive system and satisfying consumers' pursuit of healthy dietary enjoyment.
[0022] Furthermore, the coagulated modulated milk specifically defined in the present invention also includes a sweetener. The present invention uses a sweetener to replace sucrose, thereby reducing the blood sugar burden and making the coagulated modulated milk smooth and delicate in taste, which is easily welcomed by consumers who are resistant to high sugar.
[0023] The invention provides a method for preparing a coagulated modulated milk rich in dietary fiber. The method comprises the following steps: firstly, pretreated raw milk is mixed with coarse cooked oatmeal powder and fine cooked oatmeal powder and heated, and oatmeal powders with different particle sizes are gelatinized to different degrees, so that the cooked oatmeal powders with different particle sizes show good water absorption capacity and strong water retention capacity after cooling. Meanwhile, the high water absorption rate of chia seeds and the characteristics of volume expansion after water absorption are utilized to absorb the remaining water, so as to prepare a coagulated modulated milk with good stability and moderate viscosity.

[0030] The present invention provides a method for preparing the dietary fiber-rich coagulated modulated milk, comprising the following steps:
[0031] The pretreated raw milk, the coarse cooked oat flakes and the fine cooked oat flakes are mixed and heated to obtain a first material;
[0032] Mixing the first material and chia seeds again to obtain a second material;
[0033] The second material is sterilized to obtain a coagulated modulated milk.
[0034] The invention mixes and heats pretreated raw milk, coarse cooked oat flakes and fine cooked oat flakes powder to obtain a first material.
[0035] In the present invention, the method for pre-treating raw milk is preferably to remove impurities from the raw milk and then preheat it to 50-55°C, followed by degassing, homogenization and pasteurization. The homogenization temperature is preferably 70-75°C; the homogenization pressure is preferably 240-260 bar. The degassing is preferably carried out in a vacuum degassing tank.

[0037] After obtaining the first material, the present invention mixes the first material and chia seeds again to obtain the second material.
[0038] In the present invention, after the first material and chia seeds are mixed again, the chia seeds further absorb the remaining water in the first material due to their high water absorption and volume expansion after water absorption, thereby further improving the stability and viscosity of the modulated milk.
[0039] In the present invention, when a sweetener is included, it is preferred that the sweetener is mixed again with the first material together with the chia seeds.
[0040] After obtaining the second material, the present invention sterilizes the second material to obtain a coagulated modulated milk.
[0041] In the present invention, the sterilization temperature is preferably 100°C to 120°C, and may be 110°C. The sterilization time is preferably 10min to 20min, and may be 15min. After the sterilization, the solidified modulated milk is preferably filled and cooled. The present invention has no special restrictions on the filling method, and a filling method known in the art can be used.
[0042] In the present invention, the coagulated modulated milk prepared by the above method has good coagulation at 0-4°C, a silky taste, visible cooked oatmeal particles, a fat content of more than 3%, a protein content of more than 4.2%, a dietary fiber content of more than 3.3%, moderate sweetness, and is suitable for consumption by people with high sugar resistance.
[0043] The dietary fiber-rich coagulated modulated milk and the preparation method thereof provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the scope of protection of the present invention.
