Three distinct stages can be observed
i) from bleeding to the trimming step where the fillets had a temperature
from 28.5 ± 1.3 °C to 30.6 ± 0.4 °C, ii) from sorting to tumbling
where the fillets had a temperature from 24.6 ± 2.4 °C to 25.1 ±
1.5 °C and iii) from tumbling onwards where the fillets had a temperature
from 18.5 ± 1.5 °C to 19.4 ± 1.5 °C.
