Problems solved by technology

Among them, the low-temperature crystallization process is simple in principle and easy to operate, but requires a large amount of organic solvents, and the separation purity is low; in theory, it is feasible to enrich and purify polyunsaturated fatty acids with supercritical fluid extraction, but in actual operation It is difficult and requires high equipment; although the molecular distillation method can effectively prevent the thermal oxidation and decomposition of polyunsaturated fatty acids, it requires high-vacuum equipment and consumes a lot of energy; the product purity of the adsorption separation method is high, but the separation scale is relatively small. Small size, high cost, difficult to meet the requirements of large-scale industrial production

Embodiment 1

[0026] Embodiment 1: the preparation technology of functional polyunsaturated fatty acid in bee pollen, comprises the following steps:

[0027] (1) Preparation of free crude fatty acid:

[0028] Weigh 100g obtained by extraction with organic solvent or supercritical CO 2 Extract the obtained bee pollen oil, put the oil into a flask, add 2 to 5 times the volume of the oil, and a sodium hydroxide ethanol solution with a mass concentration of 3 to 10%, and place it in a HH-4 constant temperature thermostat produced by Guohua Electric Co., Ltd. In a water bath, heat and reflux at 60-70°C until the oil drops disappear as judged by the naked eye, then cool the saponified solution to room temperature; add water until the saponified crystals are completely dissolved; then add 5-15% hydrochloric acid to acidify in a water bath at 30-40°C , wherein the volume of hydrochloric acid is 2 times the volume of the aqueous solution that completely dissolves the saponified crystals; then add s...

Abstract

The invention relates to a preparation process of functional polyunsaturated fatty acid in bee pollen, which comprises the following steps: firstly, preparing free crude fatty acid; secondly, preparing urea alcohol; thirdly, performing urea inclusion reaction; fourthly, obtaining complex fatty acid; fifthly, obtaining polyunsaturated fatty acid; and sixthly, obtaining the polyunsaturated fatty acid methyl ethyl oxalate product. The invention optimizes all parameters influencing the enrichment effect, ensures the optimal process condition, improves the yield of the polyunsaturated fatty acid, has simple process, low production cost and easy industrial popularization and application, and can realize the massive production; meanwhile, the process more completely keeps the nutrient and the physiologically active of the functional polyunsaturated fatty acid, thereby being widely applied to the development and the production of relative medicine and health product thereof.

Description

technical field [0001] The invention relates to oil separation in bee pollen, in particular to a preparation process of functional polyunsaturated fatty acid in bee pollen. Background technique [0002] Bee pollen is the powdery material of the stamen and anthers collected by bees. It is rich in sugars, proteins, amino acids, vitamins, flavonoids, esters and other nutrients and various functional factors. It is called "complete nutritional food". It is often used to treat prostate diseases, cardiovascular and cerebrovascular diseases, and hyperlipidemia diseases. It has the effects of improving brain function, anti-fatigue, regulating endocrine, and anti-aging. [0003] Bee pollen is high in oil, especially polyunsaturated fatty acids. According to literature reports, the analysis of GC-MS (Gas Chromatography Mass Spectrometry) shows that rapeseed bee pollen contains a variety of unsaturated fatty acids, such as linolenic acid, oleic acid, linoleic acid, etc., and its conte...
