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...

Examples

Embodiment 1

[0030] Add 3 g of sucrose ester into 60 g of peony seed oil, stir and heat to 60° C., and stir until dissolved to obtain a core material phase. Add 5g of gelatin, 15g of modified starch and 5g of sucrose into 100mL of water, heat to 90°C, and stir to dissolve the gelatin; add 2g of sodium caseinate and 3g of citric acid, and stir until dissolved to obtain the wall material phase. The core material phase and the wall material phase are mixed, pre-emulsified in a high-speed shearing machine, and then emulsified and homogenized by a high-pressure homogenizer at 80MPa to form an emulsion, and the particle size of the emulsion reaches 200nm. Under the conditions of an inlet air temperature of 120° C. and an outlet air temperature of 10° C., the emulsion is spray-fluidized bed-dried to prepare peony seed oil microcapsules.

[0031] 98.4g of peony seed oil microcapsules were obtained by this method, in which the surface starch adhesion amount was 7%, and the embedding rate of peony s...

Embodiment 2

[0035] Add 0.5kg of phospholipids to 10kg of peony seed oil, heat to 30°C, and stir until dissolved to obtain the core material phase. Add 90L of water to 4kg of gum arabic, 10kg of modified starch, 44kg of maltose syrup and 15kg of glycerin, heat to 50°C, and stir to dissolve it; add 1kg of caseinic acid and 0.5kg of disodium hydrogen phosphate, and stir until dissolved to obtain wall Materialography. The core material phase and the wall material phase are mixed, pre-emulsified in a high-speed shearing machine, and then emulsified and homogenized by a high-pressure homogenizer at 20MPa to form a stable emulsion with a particle size of 350nm. Then, under the conditions of 90°C inlet air temperature and 60°C outlet air temperature, the emulsion is spray-fluidized bed dried to prepare peony seed oil microcapsules.

Embodiment 3

[0040]0.5kg of monoglycerides of fatty acids and 3.5kg of sucrose esters were added to 30kg of peony seed oil, heated to 50°C and stirred until dissolved to obtain a core material phase. Add 100L of water to 15kg of modified starch, 17kg of dextrin, 20kg of sucrose, and 10kg of glycerin, heat to 50°C, and stir to dissolve; add 2.5kg of potassium caseinate and 1.5kg of dipotassium hydrogen phosphate, and stir until dissolved to obtain Wall material phase. The core material phase and the wall material phase are mixed, pre-emulsified in a high-speed shearing machine, and then emulsified and homogenized by a high-pressure homogenizer at 40MPa to form an emulsion, and the particle size of the emulsion reaches 230nm. The solvent is evaporated and recovered by a three-effect evaporator to obtain a stable emulsion, and then the emulsion is spray-fluidized bed dried under the conditions of an inlet air temperature of 200°C and an outlet air temperature of 100°C to obtain peony seed oil...
