Peony seed oil microcapsule and preparation method of peony seed oil microcapsule

Abstract

The invention discloses a peony seed oil microcapsule and a preparation method of the peony seed oil microcapsule, and belongs to the technical field of food engineering. The peony seed oil microcapsule comprises a core material phase and a wall material phase. Through being metered by weight parts, the core material phase consists of 10 to 60 parts of peony seed oil and 0.5 to 5 parts of oil soluble emulsifiers; the wall material phase consists of 20 to 75 parts of wall materials, 5 to 50 parts of wall material connecting auxiliary agents, 20 to 150 parts of water, 1 to 8 parts of water-soluble emulsifiers and 0.5 to 5 parts of stabilizers. The pressure emulsification homogenizing is used, so that the particle diameter of an emulsion reaches the nanometer level, so that the particle size of an obtained product is uniform; the reconstitution capacity is good; the solubleness is good; the peony seed oil microcapsule can be dissolved in cold water; no precipitate and no floating object exist in a solution; no floating oil exists after the still standing for 48 hours; the solution can be compounded with other emulsions such as milk; the application range of the peony seed oil is expanded. The peony seed oil microcapsule and the preparation method have the advantages that the process is simple; the production cost is low; the product stability is greatly improved; and the nutrition activity of the peony seed oil is maintained.

Description

technical field [0001] The invention relates to the technical field of food engineering, in particular to a peony seed oil microcapsule and a preparation method thereof. Background technique [0002] Peony seeds are the crystallization of the essence of peony plants, which have natural longevity genes. The vegetable oil extracted from peony seeds has an unsaturated fatty acid content of more than 90%, of which the polyunsaturated fatty acid-linolenic acid content exceeds 40%, which is 140 times that of olive oil. At the same time, peony seeds contain vitamin E, phytosterols, squalene, trace elements and other nutrients that are beneficial to the human body. They have outstanding effects in anti-oxidation, liver protection, blood fat reduction, blood sugar reduction, and sun protection. Pure natural vegetable oil with great development potential. [0003] On March 22, 2011, peony seed oil was approved as a new resource food. At present, the extraction process of peony seed...

Problems solved by technology

Among them, the yeast method requires yeast purification and inactivation, the complex coacervation method needs solidification, and finally vacuum drying or freeze-drying. The operation time is long, energy consumption is high, the process is complicated, industrialization is difficult to control, and the efficiency is low.

[0004] In a word, the above method is difficult for industrial production in the preparation process of peony seed oil microcapsules, and the product stability is poor, which affects the utilization of the product in food, medicine, cosmetics, health care products, etc.
