Low temperature cooking of pork meat - Physicochemical and sensory aspects.

Low-temperature cooking is increasingly used in the food sector. This study compared three different low temperature heating methods and one conventional cooking procedure of pork meat in a combi steamer with special emphasis on sensory parameters. Low temperature, long time (LTLT) treatments over 20h at 53°C or 58°C (LTLT 53°C or 58°C) showed considerable effects on meat tenderization. Heating to a core temperature of 60°C (low temperature method=LT) at 60°C oven temperature resulted in less tender but clearly juicier meat. LTLT 53°C and LT were evaluated as being equally acceptable by the panelists. The tenderest meat (LTLT 58°C) was mainly rejected because of a crumbly and dry mouth feeling. Conventional heating to a core temperature of 80°C at 180°C oven temperature resulted in low eating quality due to high toughness and low juiciness.
