Embodiment 1

[0017] Take 50g sample and put it into the cylinder of the extraction kettle. Fish oil extraction conditions: extraction pressure: 25MPa, extraction time: 90min, extraction temperature: 40°C, CO 2 Flow rate: 25L / h, in the obtained extract, add 5% ethanol by weight, at extraction pressure 30Mpa, extraction temperature 30°C, extraction time 2h, CO 2 Extraction was carried out under the condition of a flow rate of 15 L / h to obtain an extract, which was distilled under reduced pressure, concentrated and dried to obtain 1.83 g of phospholipids containing 39.05% unsaturated fatty acids.

Embodiment 2

[0019] Take 100g sample and put it into the cylinder of the extraction kettle. Fish oil extraction conditions: extraction pressure: 30MPa, extraction time: 90min, extraction temperature: 45°C, CO 2 Flow rate: 20L / h, in the obtained extract, add ethanol with a weight ratio of 6%, at an extraction pressure of 30Mpa, an extraction temperature of 35°C, an extraction time of 2h, CO 2 %。 Extracted under the condition of flow rate 20L / h to obtain the extract, the extract was distilled under reduced pressure, concentrated and dried to obtain 3.49g phospholipids containing unsaturated fatty acids as 38.88.%.

Embodiment 3

[0021] Take 150g sample and put it into the barrel of the extraction kettle. Fish oil extraction conditions: extraction pressure: 35MPa, extraction time: 105min, extraction temperature: 50°C, CO 2 Flow rate: 30L / h, in the obtained extract, add ethanol with a weight ratio of 7%, at an extraction pressure of 35Mpa, an extraction temperature of 40°C, an extraction time of 2.5h, CO 2 Extraction was carried out under the condition of a flow rate of 17 L / h to obtain an extract, which was distilled under reduced pressure, concentrated and dried to obtain 5.85 g of phospholipids containing 38.97% of unsaturated fatty acids.

Abstract

The invention relates to a method extracting phospholipid from a marine food processing by-product roe and particularly relates to a supercritical CO2 extraction method of the phospholipid from the roe. The method includes steps of pre-heating, oil removing, extraction with ethanol carrying, and drying to obtain the phospholipid. By means of the method, not only is a problem of waste of the residual marine by-product roe solved but also a preparation source of the phospholipid is enriched. The method is low in production cost, is short in period and is simple in process. In addition, the extracted phospholipid is rich in unsaturated fatty acid.

Description

technical field [0001] The invention relates to a method for extracting phospholipids from fish roe, a by-product of marine food processing, in particular to a supercritical CO 2 A method for extracting fish lecithin. Background technique [0002] Phospholipids are a natural product that exists in nature. Almost all biological cells contain phospholipids, which are indispensable components of biological cells. Phospholipids widely exist in the brain, heart, liver and other organs of humans and animals, as well as various microorganisms, poultry eggs and seeds of most plants, and play a very important role in the normal metabolism and health of the human body. Arteriosclerosis and prevent liver cirrhosis and other physiological effects. [0003] Phospholipids can be used as amphoteric surfactants and can be widely used in the food industry. They can also be used as natural food emulsifiers and wetting agents to help improve the quality of food such as flavor and texture; ...
