✦ Synopsis

The storage (-28 degrees C) of squids prior to thermal treatment (steaming at 100 degrees C and autoclaving at 115 degrees C) was found to exert no significant influence on the available lysine and tryptophan contents of the flesh stored for no longer than 9-10 months. During a longer period of storage the contents of the studied amino acids decreased by 22.2% on an average. The -SH groups content and weight losses after thermal treatment were increasing with the time of frozen storage. The colour of squid flesh, as measured with a and b indicators (LAB system), changed most in the autoclaved samples, the colour changing towards yellow-red.

Effects of frozen storage (3-8 months at -28 "C) and heating temperatures (40, 60, 80, 100, 120 and 130 "C) on SH groups content and minced meat hardness of the Pacific hake (Merluccius productus) were studied. Of the two factors under study, temperature effects proved dominating, both on the SH dyn
