Problems solved by technology

The different feature is that the highly unsaturated fatty acids in the fatty acids of fish oil are more than the general land-produced animal and vegetable oils, so they are easily oxidized in the air and cause rancidity.

Embodiment Construction

[0018] The embodiments of the present invention will be described in detail below, however, the embodiments of the present invention are not limited thereto. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] A fish oil preparation process, comprising the following preparation steps:

[0020] The first step: selection of raw materials, fresh fish livers are selected and stored for later use; the storage methods of raw materials are divided into salting and cold storage: in the salting method, the gallbladder should be removed from the fish livers, washed with cold water, and cut into small pieces , add 10%-30% salt, mix well, and put it in a bucket; when using refrigeration, if the storage time is not long, use ice or ice salt for storage; if the storage time is long, it must be stored in a -15°C freezer. Thus...

Abstract

The invention discloses a fish oil preparation technology, comprising the following preparation procedures: strictly selecting and storing raw materials to ensure the activity of the raw materials in the whole fish oil preparation procedures; then performing steps of pulping, hydrolysis, salting out, purification and the like, and strictly controlling the temperature, a pH value and a procedure of each step, so that the fish oil preparation technology becomes simple and feasible. The prepared fish oil can meet usage requirements in a pharmacopoeia and other industries and is suitable for mass production of a general manufacturer. The fish oil preparation technology provided by the invention solves a problem of cumbersome fish oil preparation procedures in China at present.

Description

technical field [0001] The invention relates to the technical field of fish oil preparation, in particular to a fish oil preparation process. Background technique [0002] Fish oil refers to oil made from fish, including fish body oil and cod liver oil. Fish oil in a broad sense also includes fish and other aquatic animal oils such as cetaceans and dolphins. It is an important raw material for food, medicine and chemical industries. Fish oil is mainly composed of mixed triacylglycerols, which is common to the composition of general animal and vegetable oils. The different feature is that the highly unsaturated fatty acids in the fatty acids of fish oil are more than the general land-produced animal and vegetable oils, so they are easily oxidized in the air and cause rancidity. Among these highly unsaturated fatty acids, eicosapentaenoic acid and docosahexaenoic acid are active substances for reducing hyperlipidemia and have high medicinal value. In addition, cod liver oil...
