Effect of ionizing radiation on the colour and the activity of lactate dehygrogenase of pork.
Original language description
The effect of irradiation of pork was studied in relation to colour changes. Samples of M. longissimus lumborum et thoracis were obtained from the pork carcasses 24 h post mortem. Samples were irradiated using a 60Co source, at dose of 2.5 and 5 kGy; dose rate of 2.86 kGy.h-1. Non-irradiated controls were stored in the same condition as irradiated samples. The colour of a freshly cut interior surface of control and irradiated pork was measured (portable spectrophotometer Superchroma S-Spex in CIELAB system) before and after irradiation. L* and b* values of controls and irradiated pork did not change after irradiation. The a* values (red colour) of irradiated pork were significantly higher than non-irradiated. The activity of lactate dehydrogenase of pork was measured and did not change after irradiation.

Efekt ionizujícího záření na barvu a aktivitu laktátdehydrogenázy ve vepřovém mase.
Czech description
Vepřové maso bylo 24 h post mortem ozářeno 60Co v dávkách 2.5 a 5 kGy. Parametr a* (systému SIELAB) vykázal u ozářených vzorků nižší hodnotu, maso bylo méně červené. V aktivitě LD nebyly působením ionizujícího záření prokázány žádné změny.
