Title Study on temperature reaction for extraction of Crude oil from wastes of Carp
Abstract
Intention: The study will find the condition of extraction to crude fish oil in optimization temperature with the materials of subiculum of carps,using the influence of temperature in the experiment as extaraction in the way of kalium.Method: Based on traditional technology of light alkaline bydrolysis,sodium hydroxide and sodium chloride in original technology will be replaced by potassium hydroxide and potassium nitrate differently.Extraction of fish oil is done in the temperature of 65℃,70℃, 75℃,80℃,85℃,90℃and95℃ in turn in the condition of pH8.0,55mins in hydrolyzing,20mins in salting out with 4.5 percent of potassium nitrate and 30mins in centrifugalization with 3000r/min.Conclution: In the temperature of 85℃,the extraction rate is the largest and the fish oil is the clearest,keeping other condition same.This shows that the optimization temperature is 85℃ with subiculum of carps as the extraction materials.
