Meat protein processes and products.

摘要

Actin and myosin is extracted from pre-rigor muscle using a brine solution containing salt at between 3% and 18% by weight, and optionally food phosphates at 0.05% to 2 wt. %. Comminuted or chopped pre-rigor meat is mixed with the brine in a ratio between 2:1 and 4:1 to yield a slurry or paste-like mixture. The temperature is maintained below 30 DEG C to prevent the proteins denaturing. The slurry is stored in the absence of oxygen at 0 DEG C or dried e.g. by drum drying to a particulate material which can be kept at room temperature under anoxic conditions. On heating above 50 DEG C the protein product gels and by its presence in a meat product during cooking it provides good water holding properties and good binding properties. When used in processed meat products it can improve both succulence and organoleptic properties.
