Problems solved by technology

However, because there is no effective extraction method, the fat liver and goose belly fat has been discarded as garbage, or used as a cheap feed material, which not only easily causes environmental pollution, but also reduces the economic value of the fat liver and goose belly fat

Embodiment 1

[0019] Example 1: Extraction of goose belly fat mixed fatty acids (including degumming treatment step)

[0020] 1. Preparation of fatty liver and goose belly fat crude goose oil

[0021] Take a certain quality of fat liver and goose belly fat and put it at 40°C, 50°C, 60°C, 70°C, and 80°C to melt it, centrifuge it at 4000r / min for 10min while it is hot, and filter it with three layers of gauze to prepare the fat liver and goose Belly fat crude goose fat.

[0022] The analysis of the extraction rate and fatty acid content of crude goose oil shows that the optimum extraction temperature of crude goose oil is 60°C. denaturation, or the temperature is too low to separate the solid impurities, which will affect the crude goose oil extraction rate and the actual content of fatty acids.

[0023] 2. Refining of crude goose oil

[0024] Degumming treatment: Weigh a certain amount of crude goose oil, heat it to 60°C in a water bath, and keep stirring, then slowly add phosphoric acid ...

Embodiment 2

[0034] Example 2: Extraction of goose belly fat mixed fatty acids (not including the degumming treatment step)

[0035] According to the steps and conditions of Example 1, the fatty liver and goose belly fat were extracted with mixed fatty acids, except that the degumming treatment step was not included in the refining step of crude goose oil. The final detection result shows that the degumming step has a significant impact on the extraction effect of the mixed fatty acids, and the extraction rate of the mixed fatty acids only accounts for 55% of the goose belly fat total amount; simultaneously the preservation test shows that the storage time of the mixed fatty acids prepared in Example 2 4-7 days less than the mixed fatty acid prepared in Example 1.

[0036] Apparently, the extraction method and the determined optimal conditions of the present invention can effectively extract mixed fatty acids from fatty liver and goose belly fat, and the extracted mixed fatty acids can be ...

Abstract

The invention relates to a method for extracting mixed aliphatic acid from abdominal fat of foie gras, comprising a preparation of rough goose grease and an extraction of mixed aliphatic acid of goose grease, characterized in that: a refine step of rough goose grease is included between the preparation of the rough goose grease and extraction of mixed aliphatic acid of goose grease to obtain the refined goose grease, and the refining step comprises a step of degumming and a step of decoloration. Acording to the invention, the mixed aliphatic acid can be extracted from abdominal fat of foie gras efficiently, by the steps of degumming, decoloration, deodorization and the like of the rough goose grease, the components which are not glyceride are removed from the grease, the influence of the impurities to the subsequent processes is greatly reduced, and the stability and storage period of the grease are improved. The invention provides a scientific method for extracting mixed aliphatic acid from abdominal fat of foie gras, by adopting waste abdominal fat of foie gras, novel animal grease is developed, the additional value of goose products is greatly increased, so that the invention has important social benefit and economic value.

Description

technical field [0001] The invention belongs to the technical field of extraction of mixed fatty acids, and in particular relates to a method for extracting mixed fatty acids from fatty liver and goose belly fat. Background technique [0002] Fat is one of the important nutrients needed by the human body and has important physiological effects on the human body. More than 90% of fats are fatty acids, and fatty acids can be divided into saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. The three types of fatty acids are indispensable in the physiological functions of the human body. [0003] Fatty acids participate in many physiological activities of the human body. The most common function is to store energy for urgent use in human life activities. It also affects the taste and texture of food, and promotes the body's absorption of vitamins A, D, E, and K. Dehydration and condensation of fatty acids and glycerol to form phospholipids consti...
