THE EFFECT OF EXTRACTION TIME ON THE YIELD OF FISH OIL MACKEREL TUNA (Euthynus affinis) EXTRACTED WITH WET RENDERING METHOD

Abstract

ABSTRACT

Extraction is one way to produce fish oil. One of the extraction methods to get fish oil is wet rendering. The extraction time can affect the yield. This study aimed to determine the appropriate length of time using extraction by wet rendering of the resulting yield value. The research method  was an experimental method using a non-factorial complete randomized design. The treatments consisted of extraction time, namely P₁ (30 minutes), P₂ (40 minutes), and P₃ (50 minutes) at 70^oC. The analyzed parameter  was yield. The obtained results were the yield of tuna fish oil at 30 minutes (20.92%), 40 minutes (24.32%), and 50 minutes (26.17%). The highest yield of tuna fish oil was at 50 minutes. The length of time for tuna fish oil extraction affected the oil yield obtained.
