The Claim
Oil yield from saithe viscera with liver is significantly higher after 24 hours of storage at 4°C prior to silaging compared to fresh viscera, but decreases after 48–72 hours of storage at 4°C due to emulsion formation and lipid trapping.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Storing saithe viscera with liver at 4°C for 24 hours before silaging increases oil yield, but storing for 48 to 72 hours reduces oil yield because of emulsion formation and lipid trapping.
See the scientific wording
Oil yield from saithe viscera with liver increases significantly after 24 hours of storage at 4°C prior to silaging, compared to fresh viscera, likely due to enzymatic liberation of lipids, but yields decline after 48–72 hours due to emulsion formation and lipid trapping.
After storage, enzymes in the fish viscera break down fat molecules into smaller pieces, making more oil available. After one day, this releases the most oil. But after two to three days, the broken-down fats mix with water and cholesterol to form sticky globs that trap the oil, making it harder to collect.
What the research says
1 studyLetting fish guts sit for a day before processing makes more oil come out, but waiting too long (more than two days) makes the oil get stuck and harder to collect. The study proved this happens.
