What is the extraction process of refined fish oil?

Do you know how refined fish oil is made? Today, fish oil manufacturers will introduce the process of refining fish oil for you. If you are interested in it, let's go on!

Firstly, the extraction methods of fish oil in the laboratory are introduced. At present, the traditional extraction methods of fish oil reported in the literature mainly include: pressing method, cooking method, solvent extraction method, light alkaline hydrolysis method, acid hydrolysis method, supercritical fluid extraction method, etc. The basic principle is to destroy the structure of oily tissue in fish body, accelerate the thermal movement of oil molecules, reduce the viscosity surface tension, thus separate the oil the damaged tissue through various physical chemical effects.

Our PROCESS IS RAW MATERIAL ACCEPTANCE, STORAGE, ESTERIFICATION, MOLECULAR DISTILLATION, THEN DEFATTING, REESTERIFICATION, MOLECULAR DISTILLATION, FREEZING, REFINING, FILLING, WAREHOUSING, finally SHIPPING.

In the esterification process, the pretreatment crude oil ethanol are mixed, then the catalyst is added heated to 92 to 98 degrees Celsius for esterification exchange reaction. Then the esterified oil of the reaction is washed dehydrated to obtain ethanol-type fish oil.

Molecular distillation, adsorption, the ethanol type fish oil by molecular distillation after preheating, will receive the distillate to join to the concentration of 90% to 98% ethanol solution, adding urea, heated to 68 to 76 degrees for total reflux adsorption, adsorption cooling 22 to 25 degrees, after the completion of centrifugal separation, the separation of liquid for dehydration, take off the heavy metals oil reaction, have to skim oil.

Refining distillation, vacuum molecular distillation of defatted oil purification separation, refined fish oil.

Viscom Food Technology Co., Ltd. can provide different specifications, different content of fish oil according to customer requirements, effective selection of suppliers qualified crude oil. We use deep-sea fish as raw materials, using the method of molecular distillation, the product is rich in EPA DHA, is a necessary nutrient for human beings.

The above is all the content of refined fish oil manufacturers for you to introduce, to know more knowledge can pay attention to the company's official website！
