Title: Improvements in and relating to processing poultry
IPC: A23B4/12
Filed: 1957-11-12
Abstract: The shelf-life of fresh poultry is increased and the tendency for surface dehydration reduced by treating the surface of the poultry with an aqueous solution containing a small proportion of a water-soluble acid.  The birds may, for example, be chilled in a 0,05 to 0,25% solution of the acid for four hours, or passed through a 0,35 to 10% solution in one minute.  Specified acids are lactic, citric, hydrochloric, boric, trichloroacetic, phosphoric, hydroxy-butyric and hydroxy-valeric acids.  According to an example, birds were killed, scalded at 128 DEG F. defeathered and eviscerated according to standard procedures.  The treated birds were then chilled for 24 hours in tanks containing 0,17% lactic acid, dry packed in open wooden boxes and stored in a cooler maintained at 40 DEG F. shrinkage in storage was less marked p  than in the case of birds chilled in unacidified water.  Another example demonostrates the reduction in bacteriological count of birds treated with the acid solution according to the invention. Specification 840,442 is referred to.
