Embodiment 1

[0018] Embodiment 1: A kind of method of continuous phase change extraction tilapia skin oil comprises the following steps:

[0019] (1) Dry the selected high-quality tilapia skin after removing impurities at a temperature of 40° C., and control the moisture content at 15% to obtain the tilapia skin raw material.

[0020] (2) Weigh 10kg of the processed tilapia skin raw material, put it into the extraction kettle of the continuous phase change extraction device, and feed 75L of n-butane, under the conditions of extraction temperature 60°C and extraction pressure 0.2Mpa, to The flow rate of 200L / h flows through the extraction kettle, and the continuous extraction lasts for 130min. After the tilapia skin oil is extracted, it flows into the analysis kettle, the analysis temperature is 50°C, and the analysis pressure is 0.1Mpa. It becomes a gas, and then becomes a liquid through compression, flows through the extraction kettle, extracts the material again, and recycles it. The ex...

Abstract

The invention provides a method for continuous phase transition extraction of Tilapia mossambica skin oil. The continuous phase transition extraction technology is adopted; according to the extractionconditions, an extraction agent is butane, the solid-liquid ratio is 10 g: 30-75 ml, the extraction temperature is 60-100 DEG C, the extraction pressure is 0.1-1 Mpa, the flow rate of the extractionagent is 200-350 L/h, continuous extraction is performed for 130-200 min, the analysis temperature is 50-60 DEG C, and the analysis pressure is 0-0.1 Mpa. The method has the advantages that extractionis efficient, the product has no solvent residue, and the aroma component retention ratio is high; the extraction pressure and the analysis pressure are lower than supercritical values, and meanwhilethe method has the advantages that the conventional solvent extraction volume is large, the batch handling capacity is large, and the production cost is low; the obtain Tilapia mossambica skin oil isorange yellow, strong in aroma, light in fishy smell, and the functional component DHA content can reach 50% or above.

Description

technical field [0001] The invention belongs to the technical field of animal oil extraction, in particular to a method for extracting tilapia skin oil. Background technique [0002] Tilapia has a wide range of food habits, rapid growth, low oxygen resistance, growth temperature of 16-38 ℃, and strong reproduction. The climate in Guangdong is very suitable for large-scale farming of tilapia. Maoming City, Guangdong Province was awarded "China Tilapia The annual output of tilapia is huge, and the production and processing process produces a large number of by-products, most of which are not effectively utilized, which not only wastes resources but also pollutes the environment. By-products of tilapia are used to produce fish oil, which increases the added value of products and generates economic benefits. [0003] Fish oil is a kind of oil extracted from fatty fish. It is rich in omega-3 polyunsaturated fatty acids and has health benefits such as anti-inflammatory and blood ...
