Problems solved by technology

Because the content and composition of fatty acids in different types of oils are different, when the technology described in the above patents is applied to the extraction of goose oil, the yield of unsaturated fatty acids is not high, resulting in high extraction costs and poor economic benefits.

Embodiment 1

[0022] Example 1: Extraction of unsaturated fatty acids from goose belly fat (addition of mixed fatty acid extraction step)

[0023] 1. Preparation of fat liver goose belly fat crude goose oil

[0024] Crude goose oil extraction: take a certain quality of fat liver and goose belly fat and cut into 1cm 3 The left and right lumps are mashed for 5 minutes with a tissue masher at 2000 revolutions / min. The mashed goose belly fat is placed in different heat-resistant containers and heated to 40℃, 50℃, 60℃ and 70℃ in a water bath. , 80℃, keep at constant temperature for 30min, stir continuously during the heating process, centrifuge at 4000r / min for 10min while it is hot, filter with three layers of gauze, and weigh to obtain crude goose oil.

[0025] The analysis of the extraction rate and fatty acid content of crude goose oil shows that the optimal extraction temperature of crude goose oil is 60°C. At this temperature, the fat liver and goose belly fat can be quickly melted, which can pre...

Embodiment 2

[0046] Example 2: Extraction of unsaturated fatty acids from goose belly fat (excluding the step of extracting mixed fatty acids)

[0047] According to the steps and conditions of Example 1, the fat liver goose belly fat was subjected to the extraction of unsaturated fatty acids, but it was directly transferred to the unsaturated fatty acid preparation step after the refining step of the crude goose oil. The results showed that the extraction rate of unsaturated fatty acids was very high. Low, the purity of unsaturated fatty acids is not significantly different from refined goose oil, and its purity is only about 60%, which is far less than the 80%-90% of Example 1. Therefore, the mixed fatty acid extraction step of the present invention has an important effect on the extraction of goose belly fat unsaturated fatty acids, can greatly improve the purity of unsaturated fatty acids, and will not cause the loss of unsaturated fatty acids.

[0048] The extraction method and the determin...

Abstract

The invention relates to a method of extracting unsaturated fatty acid from abdominal fat of geese with fatty liver. The method comprises the steps of preparation of crude goose oil of abdominal fat of geese with fatty liver, refining of the crude goose oil and extraction of unsaturated fatty acid, and is characterized in that: there is a step of extraction of goose oil mixed fatty acid between the step of refining of the crude goose oil and the step of extraction of unsaturated fatty acid. According to the invention, refining technological parameters of degumming, decolouring and deodorization for the goose oil are improved in the method, thereby removing non-glyceride components in the unsaturated fatty acid, substantially abating influence of impurities on subsequent processes and improving stability of the unsaturated fatty acid; the step of extraction of goose oil mixed fatty acid is added before the step of extraction of unsaturated fatty acid, thereby substantially improving efficiency of subsequent extraction of the unsaturated fatty acid and purity of the unsaturated fatty acid and reducing cost. The method enables waste abdominal fat of geese with fatty liver to be fullyutilized, having an important social benefit and economic value. The extracted unsaturated fatty acid can be used in a wide variety of fields like foodstuffs, medicines and cosmetics.

Description

Technical field: [0001] The invention belongs to the technical field of extraction of unsaturated fatty acids, and specifically relates to a method for extracting unsaturated fatty acids from fat liver and goose belly fat. Background technique: [0002] Unsaturated fatty acids refer to straight-chain fatty acids with one or more double bonds and a carbon chain length of 18-22 carbon atoms. They are a special biologically active substance and have many important physiological functions. Unsaturated fatty acids are an important component of all cell membranes (involved in the synthesis of lipoproteins), which can be converted into prostaglandins, thromboxanes, leukotrienes, etc. in the body's hormone metabolism. Unsaturated fatty acids also have the functions of lowering blood cholesterol and triglycerides, regulating heart function, reducing blood viscosity, improving blood microcirculation, improving brain cell activity, enhancing memory and thinking ability, enhancing the body's...
