Problems solved by technology

[0002] Pinolenic acid is an unsaturated fatty acid in pine nuts first announced by Norwegian scientists in 1997. It is different from unsaturated fatty acids in all plants on the earth. It only exists in pine nut oil and can not only lower cholesterol (TC) , triglyceride (TG), increase high-density lipoprotein (HDL), and can also inhibit and eliminate the adverse effects of other unsaturated fatty acids on the body. It is a functional weight loss health food with development prospects. Pinot Leptinic acid can significantly reduce the body weight of nutritionally obese mice, but its stability is poor, and it is prone to denaturation reactions under high temperature, humidity and other conditions, which greatly affects its application

Embodiment 1

[0022] (1) Add excess 2% KOH ethanol solution to pine nut oil, reflux at 75°C for 1 hour, evaporate the ethanol to dryness and add water to dilute. Then extract once with petroleum ether, combine the ether layers, wash with water until neutral, separate the ether layers, add anhydrous sodium sulfate to dry, remove the sodium sulfate crystals by suction filtration, and recover the petroleum ether by rotating the filtrate under reduced pressure to obtain mixed fatty acids.

[0023] (2) Mix urea and ethanol at a ratio of 1:6 (W / V), heat and reflux at 70°C to fully dissolve, then add the pine nut oil mixed fatty acid prepared above, mixed fatty acid: urea (W / W) is 1: 1. Heat to reflux and shake continuously to make it fully mixed, and cool at room temperature for 25 minutes to crystallize. The crystallization temperature is -5°C and the crystallization time is 20 hours.

[0024] (3) Suction filtration under reduced pressure, rotary evaporation of the filtrate to remove ethanol, ad...

Embodiment 2

[0027] (1) Add excess 2.5% KOH ethanol solution to pine nut oil, reflux at 78°C for 1.2h, evaporate the ethanol to dryness and add water to dilute. Then extract twice with petroleum ether (acetone), combine the ether layer (acetone layer), wash with water until neutral, separate the ether layer (acetone layer), add anhydrous sodium sulfate to dry, remove sodium sulfate crystals by suction filtration, and depressurize the filtrate Acetone was recovered by rotary evaporation to obtain mixed fatty acids.

[0028] (2) Mix urea and ethanol at a ratio of 1:7 (W / V), heat and reflux at 73°C to fully dissolve, then add the pine nut oil mixed fatty acid prepared above, mixed fatty acid: urea (W / W) is 1: 2. Heat to reflux and shake continuously to make it fully mixed, and cool at room temperature for 20 minutes to crystallize. The crystallization temperature is -3°C and the crystallization time is 22 hours.

[0029] (3) Suction filtration under reduced pressure, rotary evaporation of th...

Embodiment 3

[0032] (1) Add excess 3% KOH ethanol solution to pine nut oil, reflux at 80°C for 1.5h, evaporate the ethanol to dryness and add water to dilute. Then extract with petroleum ether for 3 times, combine the ether layers, wash with water until neutral, separate the ether layers, add anhydrous sodium sulfate to dry, remove the sodium sulfate crystals by suction filtration, recycle the filtrate under reduced pressure to recover petroleum ether, and obtain mixed fatty acids.

[0033] (2) Mix urea and ethanol at a ratio of 1:8 (W / V), heat to reflux at 75°C to fully dissolve, then add the pine nut oil mixed fatty acid prepared above, mixed fatty acid: urea (W / W) is 1: 3. Heat to reflux and shake continuously to make it fully mixed, and cool at room temperature for 25 minutes to crystallize. The crystallization temperature is 0°C and the crystallization time is 24 hours.

Abstract

The invention belongs to the field of food processing and discloses a pinenut oil pinolenic acid microcapsule and a preparation method of the microcapsule. The pinenut oil pinolenic acid microcapsule has a weight reduction function and can reduce cholesterol (TC) and triglyceride (TG) and increase high density lipoprotein (HDL). The preparation method comprises the following preparation steps of: extracting pinolenic acid, preparing a core material solution, preparing a wall material solution, and encapsulating a microcapsule. By adopting the preparation method disclosed by the invention, the extraction rate of the pinolenic acid from pinenut oil is more than 70%, the pinenut oil pinolenic acid which is easily oxidized is microencapsulated to effectively prolong the quality guarantee period, and the encapsulation rate is more than 85%.
