Effect of freezing and salting on the activity of lipoxygenase of the muscle tissue and roe of Baltic herring

100%

nr 1

Freezing followed by frozen storage of Baltic herring at -25°C for a period of 6 months resulted in lowering the activity of lipoxygenase of the muscle tissue down to 78.2% and of the roe-down to 70.0%. The activity of the enzyme, extracted from the muscle tissue, stored in a buffer solution at -10, -18, and -25°C declined in reverse proportion to the increase of the storage temperature. Salting of herring, until they reached from 9.8 to 18.5% of salt content in their muscle tissue caused a decline in the activity of lipoxygenase, which was in direct proportion to the concentration of salt. Lipoxygenase of roe was catalysed more extensively during the weak salting (9.8% NaCl) than it was during medium- (12.3% NaCl) or strong salting (18.3% NaCl).

Antlers and skulls collected for chemical analysis originated from roe deer Capreolus capreolus (Linnaeus, 1758) bucks bagged in the Rogów hunting district in central Poland. Antlers were divided by the quality and by the age. The specific gravity of the antlers as well as nitrogen, calcium, phosphorus, magnesium and sodium content were measured. The highest nitrogen content was in corkscrew antlers, which also had the lowest density. Corkscrew antlers contained the lowest calcium, phosphorus, magnesium and sodium content. The highest amounts of these biogens were found in regressive and year-old antlers. Ca/P ratios were measured and relatively consistent, while Ca/N ratios varied and were lowest in year-old antlers.
