Figure 5.

Conceptual representation of the temperature dynamics of the fresh fishery products when stored/transported under the currently authorised condition (CFFP) in comparison with the alternative condition (superchilled; SFFP) to the point in which all ice has melted (i.e. α = X_ice = 0)

• The initial fish temperature in the fish matrix is denoted by ${\mathrm{T}}_{\mathrm{C}}^0$ for CFFP and ${\mathrm{T}}_{\mathrm{S}}^0$ for SFFP; the temperatures after storage and transport are ${\mathrm{T}}_{\mathrm{C}}^{\mathrm{end}}$ and ${\mathrm{T}}_{\mathrm{S}}^{\mathrm{end}}$ for CFFP and SFFP, respectively; the mass of ice in CFFP is m_ice, and the ice fraction in the SFFP is X_ice. (a) under practices ensuring that there is ice in the box of CFFP and the SFFP maintains an ice fraction during the whole period of storage and transport; (b) when the absorbed heat during storage/transport completely melts the ice inside the SFFP and raises fish temperature above 0°C, while there is still ice in the box of CFFP.
