Technical Field

[0001] The invention relates to the technical field of vegetable oil diglyceride processing, and in particular to a method for preparing and eating high-energy food for the elderly. Background Art

[0002] Tea oil is a high-quality edible oil extracted from tea seeds. It contains 80% oleic acid and a higher content of polyunsaturated fatty acids such as linoleic acid. In addition, it is also rich in a variety of biologically active substances, such as tocopherol, β-carotene, tea polyphenols, phytosterols, etc. After consumption, it can play an antioxidant, anti-inflammatory, regulate cardiovascular health, enhance immunity and other physiological regulatory effects.

[0003] As a healthy dietary oil, diglyceride is easily digested and absorbed after consumption, can effectively prevent fat accumulation in the human body, and has physiological regulation functions of regulating blood lipids, inhibiting weight gain, and alleviating diabetes and its complications. At the same time, its high solubility can provide products with higher foam durability and better flavor. As an additive, it can significantly improve the dispersibility, stability and dispersibility of products, increase the content of unsaturated fatty acids in products, improve product viscoelasticity, and improve structural characteristics. This shows that tea oil diglyceride oil has extremely high application value in the food industry and has broad development prospects.

[0004] However, due to the shortcomings of tea oil diglyceride, such as short storage time and limited processing methods, and the fact that it is a liquid oil and is not easily soluble in water, it will give the consumer a greasy taste when consumed, which affects the application scope of tea oil diglyceride. Summary of the invention
