The situation of chilling in water and chilling in air combined with spraying was examined. The evaluation concerned chilling in air combined with spraying, and chilling by immersion within a day, repeated twice within a four-hour period consecutively after each other. Another observation was made in chilling in air combined with spraying in a different shift when the processing line was operated at a lower speed. The average value of absorbed water content was 0.7 % in the process of chilling in air combined with water spraying at a faster line operation (95 broilers per minute); it complies with the required limit value of maximally 2 %; repeated measurements within a shift indicated the average value 1.19 % of absorbed water, which is also within the limit values. As expected, the average value of absorbed water content was the highest of all three evaluations of this chilling process at a slower line operation (75 broilers per minute): 1.73 % of absorbed water, but still complying with the EU limit value. The average value of absorbed water content at chilling by immersion was 3.26 %, also complying with the EU limit (4.5 %).
