preparation example Construction

[0035] 1) Preparation of mixed fatty acids: Add the refined goose oil into 1mol / L NaOH-ethanol solution in a ratio of 1:4, stir magnetically for a period of time to completely dissolve it, then transfer it to a 1000ml three-neck flask, reflux in a water bath for saponification for a period of time, To obtain a saponified solution, distill ethanol out under reduced pressure, add water to completely dissolve the saponified product, acidify with 10% HCl to pH 2-3 under constant temperature and constant speed stirring, add a certain volume of n-hexane for extraction, wash with warm water until neutral, reduce Evaporate the solvent under pressure, add anhydrous sodium sulfate for dehydration, and filter with suction to obtain mixed fatty acids. Wherein, the preparation conditions of the mixed fatty acid are: saponification temperature 82° C., reaction time 60 minutes.

[0036] 2) Preparation of diglycerides: Weigh glycerol and mixed fatty acids in a small flask at a ratio of 1:1.05...

Embodiment 1

[0043] Embodiment 1: Microencapsulation optimal process condition screening test

[0044] (1) Preparation of emulsion

[0045] Dissolve β-cyclodextrin and sodium caseinate in water at a mass ratio of 1.5:1, and ultrasonically treat it for 3 minutes. After it is fully dissolved, add 1% sodium carboxymethylcellulose (CMC), and stir The goose oil diglyceride after ultrasonic treatment is slowly added to make it fully and homogeneously mixed.

[0046] (2) Emulsion freeze-drying treatment

[0047] Pour the emulsion into a plastic petri dish, pre-cool at minus 40°C, put it in a freeze dryer for 15 hours and then take it out.

[0048] (3) Determination of microcapsule embedding rate

[0049] ① Determination of oil content on the surface of microcapsules: Take 2.0g sample, add 50ml of petroleum ether, shake vigorously for 2 minutes, filter with suction, collect the filtrate and evaporate the solvent in a rotary evaporator, and measure the surface oil quality by weight loss method. ...

Embodiment 2

[0073] Embodiment 2: Microencapsulation optimal process condition regression test

[0074] Add 134g of β-cyclodextrin into distilled water preheated to 50°C to dissolve completely, then slowly add 110g of sodium caseinate according to the ratio of β-cyclodextrin to sodium caseinate at 1.22:1, and wait until it is fully After dissolving, 7.56 g of sodium carboxymethylcellulose (CMC) equivalent to 0.7% by mass was added, and 100 g of goose oil diglyceride was slowly added under high-speed stirring and then homogenized. Pour the emulsion into a plastic petri dish, pre-cool at minus 40°C, put it in a freeze dryer for 15 hours and take it out. The conditions for vacuum freeze-drying are: -40°C and 80Pa. After 5 repeated tests, the embedding rates of the obtained microcapsule products were 93.27%, 93.45%, 93.37%, 93.26%, and 93.05%, respectively, and the average embedding rate was 93.28%, which was basically consistent with the results of the implementation case 1; The invented pro...

Abstract

A purpose of the present invention is to provide goose oil diacylglycerol microcapsules, which comprise a core material and a wall material, and is characterized in that the core material is goose oil diacylglycerol, and the wall material is a beta-cyclodextrin and sodium caseinate mixture. According to the present invention, the core material and the wall material are respectively subjected to an ultrasonic treatment, such that the wall material is easily dissolved in water, and the core material is easily dissolved in an emulsified liquid so as to substantially increase an emulsified liquid concentration, reduce a freeze-drying time, and improve a microcapsule encapsulation rate and production efficiency; and a freeze drying method is adopted so as to effectively prevent goose oil diacylglycerol loss during the preparation process, avoid the disadvantage of high temperature of the existing method, filling the goose oil diacylglycerol encapsulation technology research gap, provide a new method for new goose oil product research and development, and provide important social values and economic values.

Description

technical field [0001] The invention belongs to the technical field of oil microcapsule preparation, in particular to a goose oil diglyceride microcapsule. Background technique [0002] Goose oil has the characteristics of low melting point, unique fragrance, low cholesterol content and high unsaturated fatty acid content. However, there are few studies on goose oil at present, and most of the goose oil is used as feed and causes waste. Using fat deposited in goose liver and subcutaneous parts as fatty acid donors to prepare diglycerides can turn waste into treasure and greatly increase the economic value of goose oil and increase the added value of the product. [0003] Diacylglycerol is a product obtained by esterification of glycerol (glycerol) with two fatty acids. It is divided into two isomers, 1,3-diglyceride and 1,2-diglyceride. Studies have shown that diacylglycerol (DG) has important functions in reducing blood lipids, reducing visceral fat, and inhibiting weigh...
