Abstract

The invention discloses high-temperature-resistant unsaturated fatty acid fat microcapsule powder and a preparation method thereof. The preparation method comprises the following steps of adding a first-layer wall material, sodium caseinate, a water-soluble antioxidant and a stabilizing agent to water to obtain a water phase; adding glyceryl monostearate, glycerol distearates and an oil-soluble antioxidant to unsaturated fatty acid fat to obtain an oil phase; and adding the oil phase to the water phase, performing shearing and homogenizing, adding a second-layer wall material to form final emulsion, then performing spray drying, and performing screening so as to obtain the high-temperature-resistant unsaturated fatty acid fat microcapsule powder. According to the high-temperature-resistantunsaturated fatty acid fat microcapsule powder and the preparation method thereof disclosed by the invention, a dual-embedding technique is adopted, the second-layer wall material is made from high-temperature-resistant macromolecule materials, and a layer of high-temperature-resistant films is formed on the surface of a product, so that the air permeability is low, and oxygen, nitrogen, carbon dioxide and the like can hardly pass through the film; and in addition, water and oil diphase antioxidants synergistically strengthen the oxidation resistance of the microcapsule powder, the oxidationof outside high temperature environment and the oxygen on the unsaturated fatty acid fat is effectively prevented, the shelf life of the product is prolonged, the stability of the product is improved,and the preparation process is environmental-friendly.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a high-temperature-resistant unsaturated fatty acid oil microcapsule powder and a preparation method thereof. Background technique [0002] Unsaturated fatty acids refer to fatty acids containing at least one double bond. They are divided into omega-3, omega-6, omega-9 and other fatty acids according to the position of the first double bond. The common ones are oleic acid. , linoleic acid, linolenic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), etc. are essential fatty acids for the human body and can only be taken from food to meet the body's needs. Unsaturated fatty acids have significant curative effects in the prevention and treatment of cardiovascular and cerebrovascular diseases, "three highs", cancer and other diseases. They also have the functions of promoting the growth of physiological cells, regulating the body's immune function and...
