In one aspect of the invention, a dairy product is provided. According to an embodiment of the invention, the dairy product comprises, based on the total mass of the dairy product: 0.3-8.0 mass% of a protein raw material; 0.5 to 1.0 mass% of a vitamin raw material; 1.5-2.0 mass% of a mineral material; 0.4-7.0 mass% of a fat raw material; 0.2-0.5 mass% of stabilizer and/or emulsifier raw material; 0.05-0.1 mass% of a buffer salt raw material; 1.5 to 17 mass% of a saccharide raw material; 1-3 mass% of a dietary fiber raw material; and the balance raw milk, dairy product and/or water.
The composition of the preferred dairy product is obtained through a large number of experiments, wherein the protein raw material, the vitamin raw material, the mineral matter, the carbohydrate raw material, the fat raw material and the dietary fiber raw material provide rich nutritional ingredients for the dairy product, and can meet nutritional requirements of different crowds, particularly crowds over 10 years old. Meanwhile, the dairy product is endowed with excellent flavor and mouthfeel. In addition, the stabilizer and/or emulsifier raw material and the buffering salt raw material ensure stronger stability and better flavor and mouthfeel of the dairy product.
Through intensive research, the proportion of the components influences the flavor, taste and stability of the dairy product. For example, if the protein material content is high, the dairy product is easy to be burnt, and the taste is strong, so that the dairy product is not easily accepted by most people. In addition, excessive protein can also cause the instability of a product system, and phenomena such as water separation and delamination are easy to occur. If the vitamin raw materials are too much, the body discomfort of people eating the vitamin food is easy to cause, such as symptoms of nausea, vomiting, diarrhea and the like. If the mineral raw materials are too much, protein precipitation is easily caused. The inventor obtains the optimal component proportion through a plurality of experiments, so that the dairy product according to the embodiment of the invention has at least one of the following advantages: rich nutrition, good taste and stability.
It will be understood by those skilled in the art that the term "protein material" as used herein refers to a material that provides protein, but does not include raw milk and skim milk.
According to an embodiment of the invention, the protein material is selected from at least one of concentrated milk protein, soy protein isolate and sodium caseinate. The inventor finds that compared with other protein sources, the concentrated milk protein, the soy protein isolate and the sodium caseinate can provide abundant protein for the dairy product, the dairy product has good taste, can be accepted by most people, and is easy to form a stable system. However, other types of protein materials are too strong in protein taste to be accepted by most people. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the vitamin raw material is selected from at least one of vitamin a, vitamin D3, vitamin E acetate, vitamin K1, thiamine hydrochloride, riboflavin, pyridoxine hydrochloride, ascorbic acid, taurine, calcium pantothenate, biotin, folic acid, nicotinamide, vitamin B12, and iodine. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the carbohydrate material is selected from at least one of white granulated sugar, fructo-oligosaccharides and maltodextrins. The inventor finds that the white granulated sugar, the fructo-oligosaccharide and the maltodextrin can not only provide abundant carbohydrate for the dairy product, but also endow the dairy product with pleasant sweet taste compared with saccharides from other sources in a plurality of saccharide raw materials. Meanwhile, the maltodextrin can endow the dairy product with smooth and exquisite mouthfeel, and can improve the stability of the dairy product. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the fat feedstock is selected from at least one of medium chain triglycerides, alpha-linolenic acid and linoleic acid. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the present invention, the mineral raw material is selected from at least one of calcium carbonate, anhydrous copper sulfate, monopotassium phosphate, ferric pyrophosphate, basic magnesium carbonate, manganese sulfate, potassium citrate, sodium selenite, zinc sulfate monohydrate, sodium chloride, and sodium citrate. The inventor finds that the minerals can not only improve the nutritional value of the dairy product, but also are not easy to combine with protein compared with minerals from other sources, so that the protein precipitation is effectively prevented, and the stability of the system is ensured. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the raw material of the stabilizer and/or emulsifier is selected from at least one of microcrystalline cellulose, glyceryl monostearate, gellan gum and carrageenan. The inventor finds that the raw materials of the stabilizing agent and/or the emulsifying agent can not only ensure the long-term stability of the product, but also help the protein component in milk to be emulsified and dispersed, and can also play a role in quickly and effectively dispersing protein raw materials, such as concentrated milk protein, sodium caseinate, soybean protein and the like, and improve the mouthfeel of the product. Meanwhile, the suspending agent helps to suspend insoluble compounds in a system with various metal cations, complex free metal ions, accelerate oxidation of the cations on fatty acid and the like, and simultaneously can improve the mouthfeel of the product. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the buffer salt starting material is selected from at least one of sodium tripolyphosphate and sodium hexametaphosphate. The inventor finds that sodium tripolyphosphate and sodium hexametaphosphate in a plurality of buffer salt raw materials can be matched with the minerals to prevent protein denaturation caused by the minerals, and simultaneously, the pH value of the system is kept at a relatively constant level, so that the system has better stability. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the dietary fibre material is selected from hydrolysed oat flour. The inventor unexpectedly finds that in a plurality of dietary fiber raw materials, the hydrolyzed oat flour can not only provide rich dietary fiber for dairy products, but also improve the mouthfeel of the dairy products and cover the tastes of vitamins, minerals and grease in the products, has the advantages of easy dissolution, difficult precipitation and the like, and is easily accepted by most people. However, although the unhydrolyzed oat flour has the flavor of oat, it is not easily dissolved, easily precipitated, and has a rough mouthfeel. Therefore, the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the invention, the dairy product comprises, based on the total mass of the dairy product: 2.5 to 5.0 mass% of concentrated milk protein, 0.3 to 2.0 mass% of isolated soy protein, and 0.5 to 1.0 mass% of sodium caseinate; 0.5 to 1.0 mass% of a vitamin; 1.5 to 2.0 mass% of a mineral; 5.0 to 6.0 mass% of medium chain triglycerides; 0.4 to 1.0 mass% of a vegetable oil containing 40 mass% of alpha-linolenic acid and 8.5 mass% of linoleic acid; 0.2 to 0.5 mass% of a stabilizer; 0.05 to 0.1 mass% of a buffer salt; 1.5-2.0 mass% of white granulated sugar; 3.0 to 5.0 mass% of fructooligosaccharide; 3 to 10 mass% of maltodextrin; 1-3 mass% of hydrolyzed oat flour; and the balance raw milk, dairy product and/or water. The inventor obtains the better components and proportion through a large number of experiments, so that the dairy product further has richer nutrition, excellent flavor and taste or stronger stability. The dairy product per 100mL contains energy no less than 295kJ (70kcal), and protein no less than 0.7g/100kJ (3g/100kcal), wherein the high-quality protein accounts for no less than 50%.
Method for preparing dairy products
In another aspect of the invention, the invention proposes a method for preparing a dairy product as described above. According to an embodiment of the invention, the method comprises: performing first mixing treatment on a protein raw material and a part of raw milk, dairy products and/or water, and performing standing treatment on the obtained mixed solution to obtain a first mixed solution; carrying out second mixing treatment on the raw materials of the stabilizer and/or the emulsifier and the other part of raw milk, dairy products and/or water, and carrying out cooling treatment on the obtained mixed solution so as to obtain a second mixed solution; performing third mixing treatment on the second mixed solution, the vitamin raw material, the mineral raw material, the buffer salt raw material, the fat raw material, the carbohydrate raw material and the dietary fiber raw material to obtain a third mixed solution; and performing constant volume on the third mixed solution by using the residual milk, the dairy product and/or water, and performing homogenization and sterilization treatment on the obtained mixed solution so as to obtain the dairy product.
The inventors have found that when all the raw materials are mixed at the same time, many components are not sufficiently dissolved and are liable to agglomerate. Further, by mixing the raw materials in batches and then mixing the raw material liquids, the components in the obtained feed liquid are fully dissolved and no agglomeration phenomenon occurs. Further, the materials are refined through homogenization treatment, so that the dairy product is fine and smooth in taste. And then the sterilization treatment is carried out to kill harmful bacteria and prolong the shelf life of the product. Thus, the dairy product obtained by the method for preparing the dairy product has at least one of the following advantages: rich nutrition, good taste and stability.
According to an embodiment of the present invention, the first mixing treatment is stirring at 45 to 55 ℃ for 10 to 60 minutes. Therefore, the materials are conveniently and fully dissolved and uniformly mixed. Therefore, the dairy product obtained by the method for preparing the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to the embodiment of the invention, the standing treatment time is 10-60 minutes. The inventor finds that under the condition, the protein can be fully hydrated, so that the protein has better stability. Therefore, the dairy product obtained by the method for preparing the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to the embodiment of the invention, the second mixing treatment is to stir at 65-75 ℃ for 10-30 minutes and then cool to 40 ℃. Therefore, the stabilizer and/or the emulsifier can be dissolved sufficiently, and the effect of protecting the protein is improved. Therefore, the dairy product obtained by the method for preparing the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
According to an embodiment of the present invention, the homogenization is performed at a temperature of 50 to 80 ℃ and a pressure of 150 to 200 bar. Therefore, the materials are further refined, the dairy product is endowed with fine mouthfeel, and the stability is strong. Therefore, the dairy product obtained by the method for preparing the dairy product disclosed by the embodiment of the invention further has richer nutrition, excellent flavor and mouthfeel or stronger stability.
