Embodiment 1

[0026] Take 100 parts of soybean lecithin, 200 parts of commercially available linseed oil, and 130 parts of Novozymes immobilized phospholipase A, mix them, control the reaction temperature at 45°C, and stir for 48 hours; after the reaction stops, centrifuge to remove the phospholipase, and then extract with acetone The unreacted linseed oil was removed, and the acetone insoluble matter was dried to obtain the product. The fatty acid composition was analyzed by gas chromatography in Table 1, and the acid value, iodine value, and phosphorus content of the product were shown in Table 2.

Embodiment 2

[0028] Take 100 parts of soybean lecithin, ethanol hydrolysis of perilla oil to obtain 400 parts of perilla oil ethyl ester, mix with 10 parts of Shenzhen Lvweikang alkaline lipase LTK-T100, control the reaction temperature at 55°C, and stir for 12 hours; the reaction is stopped After filtration to remove lipase, and then through supercritical CO 2 Extraction removes unreacted fatty acid ethyl ester, supercritical CO 2 The insoluble matter was dried to obtain the product, and its fatty acid composition was analyzed by gas chromatography in Table 1, and the acid value, iodine value, and phosphorus content of the product were shown in Table 2.

Embodiment 3

[0030] Take 100 parts of phosphatidylcholine (content 80%, PC80), 600 parts of kiwi oil ethyl ester obtained by methanolysis of kiwi oil, and 20 parts of Novozymes TLIM lipase, mix, control the reaction temperature at 60°C, and stir for 36 hours After reaction stops, filter and remove lipase, then remove unreacted fatty acid methyl ester by acetone extraction, acetone insolubles are dried to obtain product, its fatty acid composition is shown in Table 1 by gas chromatography, product acid value, iodine value, phosphorus The contents are shown in Table 2.

Abstract

Phospholipid with coordinative fatty acid ratio is characterized by less than 30mgKOH / g of acid value, 95-140gI2 / 100g of iodine value and 2.8-3.8wt percent of phosphorus content; the weight percentage of the compositions of the fatty acid contained in the phospholipid with coordinative fatty acid ratio is as follows: 10-16wt percent of saturated fatty acid, 14-22wt percent of mono-unsaturated fatty acid and 63-75wt percent of polyunsaturated fatty acid, wherein the N6 series of polyunsaturated fatty acid accounts for 45-60wt percent and the N3 series of polyunsaturated fatty acid accounts for 10-30wt percent. The invention has the advantages of introducing the fatty acid into the phospholipid at a coordinative ratio, being capable of bringing the fatty acid into cells by utilizing the emulsification property of the phospholipid, promoting the absorption and utilization to the fatty acid by the human body, having synergic action of the N3 series of polyunsaturated fatty acid and the phospholipid, and playing dual physiological roles thereof.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to a phospholipid with coordinated fatty acid ratio and a preparation method thereof. Background technique [0002] Phospholipids are lipid compounds containing phospholipid roots, which are the basic substances of life. The cell membrane is composed of about 70% protein and about 30% phospholipid. Phospholipids are composed of phosphatidylcholine (lecithin), phosphatidylinositol, phosphatidylethanolamine (cephalin), and phosphatidic acid. These phospholipids play corresponding functions on various parts and organs of the human body respectively. Phospholipids mainly have the following functions: ① clean blood, decompose excessive blood lipids and excessive cholesterol, clean blood vessels, and make blood vessels circulate smoothly. The harmless micromolecular state of the human body can be dissolved in water and excreted from the body; ② nootropic effect, human nerve cells and br...
