Alligator oil and efficient biologic preparation method thereof

Abstract

The invention discloses alligator oil and an efficient biologic preparation method thereof and belongs to the field of crocodile fat processing. The alligator oil contains a large amount of unsaturated fatty acid with a medicinal healthcare function and is easily oxidized and inactivated; in order to solve the problems of low extraction efficiency, complex process, low oil quality, complex discoloration and deodorization processes, serious damage to the components of the alligator oil, and the like, of the traditional alligator oil, the invention provides an efficient, quick, low-cost and high-quality preparation method for the alligator oil; the method comprises the following steps: bio-enzyme extraction, physical adsorption discoloration and microbial fermentation deodorization; the condition is mild; the method has significance in fully utilizing the valuable alligator oil resource and preparing the high-quality alligator oil; and a guarantee is supplied for the application of the alligator oil in drugs, healthcare products, food and household chemicals.

Description

technical field [0001] The invention belongs to a preparation method of crocodile oil, in particular to a high-efficiency biological preparation method of crocodile oil. Background technique [0002] Crocodiles are close relatives of extinct dinosaurs and are the oldest reptiles. They have lived on the earth for more than 230 million years, so they are called "living fossils". Crocodiles are reptiles and crocodiles. There are 8 genera and 25 species in 3 families, and there are only 21 species in 3 families in the world. Studies have shown that the whole body of crocodiles is full of treasures, which have extremely high pharmacological, nourishing and commercial value. In addition, crocodiles also have a strong autoimmune system. In recent years, the demand for crocodile products in the international market has been increasing day by day. Crocodiles are a new breed of economic animals developed in recent years. [0003] Li Shizhen's "Compendium of Materia Medica" records ...

AI Technical Summary

Problems solved by technology

But above-mentioned these methods all have serious deficiency, all can easily cause problems such as solvent residue and environmental pollution as alkali hydrolysis method, organic solvent extraction method; Underpressure distillation needs special instrument and equipment and extraction rate is low; Supercritical CO 2 The extraction method is expensive, the extraction time is long, the energy consumption is large, and the extraction rate is low; the disadvantage of the dry method is that the extraction temperature is high, the unsaturated fatty acid is easily destroyed, the color is deep, and the fishy smell is heavy.

The decolorization methods of fish oil include the use of activated carbon, activated clay, etc. Physical and chemical methods are mostly used in the research on deodorization. Activated carbon has a better decolorization effect, but the loss of protein is more, and separation is difficult. The components of fish oil after deodorization by chemical reagents severely damaged

In the patent search for decolorization and deodorization of crocodile oil, there is an article CN201310451356.2, which uses activated carbon and activated clay for decolorization, and the chemical method of adding and subtracting acid to deodorize, and there is no extraction method
