Popis: Chanks of freshwater tront muscle were immersed in sorbitol solutions (0% to 60%), under different vacuum conditions, for up to 30 min at 5 °C, Molsture loss, weight change, and sorbitol uptable were measured or calculated by mass balance, and cryoprotection during subsequent freezing and thawing was monitored as change in myosin Ca 3+ ATPase activity. Vacuum treatment had no effect on measured parameters. Initial sorbinal uptake and weight loss were greater at higher sorbitol concentrations, but adequate cryoprotection was achieved by all treatments when diffusion time following immersion was extended sufficiently. Injection of 60% sorbitol was fasier in achieving desired levels of sorbital in flsh ment and induced excellent cryoprotection. diffesion, vacuum, trout, sorbitol, ATPase.
