โœฆ Synopsis


Anchovy were stored at 17ยฐC. 8ยฐC. 0ยฐC and -6ยฐC. Samples were withdrawn periodically and the extracted lipids analysed for free fatty acids (FFA) and phosphorus (P) content. From the results of these analyses it was possible to calculate the rates of enzymatic hydrolysis of the phospholipids and the neutral lipids. Phospholipids hydrolysed much faster than neutral lipids at the four temperatures. An Arrhenius plot showed that at about -29ยฐC the two rates were identical. Der Gehalt an freien Fettsauren in Fischol, Teil IV: Gesehwindigkeiten zur Bildung von freien Fettsiiuren nus Phospholipiden uad Neutrnllipiden im bei verschiedenen Tempernturen gelagerten Anchovis ( Engradis enpensis) Der Anchovis wurde bei 17ยฐC. 8ยฐC. 0ยฐC und -6ยฐC gelagert. Es wurden in regelmaDigen Zeitabstanden Proben entnommen und beziiglich ihres qehalts an freien Fettsauren und Phosphor analysiert. Die Ergebnisse dieser Analysen ermoglichten die Berechnung der Geschwindigkeiten der enzymatischen Hydrolyse von Phospholipiden und Neutrallipiden. Phospholipide hydrolysierten erheblich schneller als Neutrallipide bei den vier Ternperaturen. Die Arrhenius-Darstellung ergab, daO bei ungefahr -29ยฐC beide Geschwindigkeiten identisch waren.

Long-term storage of fish oils frequently leads to deterioration in quality due to enzymatic formation of free fatty acids (FFA). The present investigation has identified a number of chemical characteristics which can serve as indices in predicting which oils arc liable to show FFA escalation on sto
