Abstract

The invention provides fish oil microcapsule powder and a preparation method thereof, and relates to the technical field of food and feed preparations. The fish oil microcapsule powder is prepared from various fish oil micro-capsule powders, an emulsifier, an anti-caking agent and a filling agent. The preparation method comprises the following steps: (1) dissolving monoglyceride, diglyceride, ascorbyl palmitate and vitamin E in fish oil to obtain an oil suspension A; (2) dissolving sodium caseinate, maltodextrin and cane sugar in water to prepare a solution B; (3) putting the solution A and the solution B into a high-speed shearing machine, and adjusting the pH value of the solution to 7.0-7.5 by using dipotassium phosphate; carrying out shearing and emulsifying to obtain fish oil emulsified liquid; (4) homogenizing the emulsified liquid under the pressure of 30MPa-40MPa by a homogenizer to obtain fish oil microcapsule liquid; and (5) uniformly mixing the prepared fish oil microcapsuleliquid with the anti-caking agent to prepare the fish oil microcapsule powder. The fish oil microcapsule powder prepared by the invention can be used as an auxiliary material for food and feed addition, and provides wider and more convenient application of fish oil in food and feed industries.

Description

technical field [0001] The invention relates to the technical field of food and feed preparations, in particular to fish oil microcapsule powder and a preparation method thereof. Background technique [0002] Fish oil is oil extracted from fish. Unlike other animal oils, which are mainly saturated fatty acids, fish oil is rich in polyunsaturated fatty acids. The main components are EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) arachidonic acid), and essential fatty acids such as arachidonic acid, linolenic acid and linoleic acid. High-quality or highly processed fish oil is mainly used in food, health care products and medicines. Fish oil has a fishy smell and is easily oxidized, so its application is limited. [0003] Microcapsule technology can effectively embed fish oil, so that the fishy smell of fish oil is embedded in the microcapsule, which can eliminate most of the fishy smell of fish oil, and can also effectively isolate oxygen to prevent fish oil from b...
