The present invention relates to a cream and preparation method thereof, in particular to a non-hydrogenated mixed dairy and non-dairy cream and preparation method thereof.
In China's traditional non-dairy cream production, hydrogenated vegetable oil is the main raw material. Hydrogenated vegetable oil is artificial oil, which is produced by catalytic hydrogenation of common vegetable oils under certain temperature and pressure. The hydrogenated vegetable oil system is uniform, has no odor, and its hardness increases, with a high melting point, so that it can maintain a solid shape at room temperature, and its plasticity, fusion, and emulsification are increased. In addition, it can extend the shelf life of products; therefore, it has been widely used in food processing. However, some hydrogenated vegetable oils that have not been fully hydrogenated contain trans-fatty acids, which do not have the nutrients of pure natural vegetable oils and are not good for human health. Trans-fatty acids easily induce coronary heart disease, heart disease, arteriosclerosis, obesity and diabetes, and etc. In addition to generation of some trans-fatty acids, some metal catalysts may remain in the process of hydrogenated oil processing. These substances have impacts on human health, which severely limits the safety of their application in food processing.
Today, with the increasing demand for high quality livings, people are more concerned about the food safety. Health and safety have become the primary criteria for consumers to purchase products. Therefore, it is necessary to use non-hydrogenated vegetable oil instead of hydrogenated vegetable oil in food processing. Non-hydrogenated fats and oils are derived from pure natural plants that are not hydrogenated. Because they are not hydrogenated, they do not contain trans fatty acids. This is beneficial to human health. In terms of nutrition, it is nutritious and does not contain trans fatty acids and cholesterol, with high content of unsaturated fatty acids. In addition, because non-hydrogenated vegetable oil can be normally involved in the human metabolism, with high nutritional value and benefits human health, it is ideal edible oil. However, when non-hydrogenated oils and fats are used in foods, they have the shortcomings of soft texture, difficulty in operation and poor flavor and taste, which seriously limit their applications in food processing. Therefore, in order to solve the above problems, in the present invention, by using mixed emulsifiers and stabilizers and combining two non-hydrogenated oils and fats, these shortcomings of non-hydrogenated oils and fats can be overcome. The emulsification uniformity, stability, operability and tastes of the non-hydrogenated oils/fats are improved, to prepare non-hydrogenated mixed dairy and non-dairy cream, enhancing the nutritional value and health properties of the products. The cream prepared in the invention has good taste and flavor, with a stable system, meeting needs of customers.
An object of the present invention is to provide a non-hydrogenated mixed dairy and non-dairy cream and a preparation method thereof, to solve the foregoing problems in the prior art.
To achieve the above object, the present invention provides a non-hydrogenated mixed dairy and non-dairy cream, comprising the following raw materials in weight percent:

The non-hydrogenated vegetable oil is prepared from refined palm oil and coconut oil; the ratio of the refined palm oil to the coconut oil is 9-10:2-3.
Further, the present invention provides a method for preparing a non-hydrogenated mixed dairy and non-dairy cream using non-hydrogenated vegetable oils as raw materials. The non-hydrogenated cream made by this method has good flavor and taste and operability, mainly comprising the following steps:
Melt and heat non-hydrogenated vegetable oil to 60-65° C.; add sorbitan monostearate, stearyl monoglyceridyl citrate, lactate monoglyceride, sodium stearoyl lactylate, mono- and diglycerides of fatty acids, sucrose fatty acid ester, polyglycerol ester, carrageenan, microcrystalline cellulose, modified cellulose and sodium caseinate, and potassium dihydrogen phosphate; stir the mixture to disperse evenly to obtain an oil-phase mixture. Dissolve sugar, glucose syrup, and fat-containing dairy product in water at 60-70° C. to obtain an aqueous-phase mixture. Add the aqueous phase to the oil phase, stir evenly and perform pasteurization. Then, perform homogenization, and stir it at a temperature of below 10° C. for 1 hour. Perform filling and preserve the product under a frozen condition below −18° C.
The non-hydrogenated vegetable oil in the present invention is made by mixing non-hydrogenated refined palm kernel oil and coconut oil.
