4.4. Flavour aspects and legislatWe are left with the suggestion that up to 0.03 mol/kg succinate
and 0.02 mol/kg glutamate should be added to minces in MAP.
Succinate’s taste (seashell) threshold of 0.03% in pure water is by
far exceeded then. Even the endogenous concentration of succinate
exceeds this taste threshold. The taste threshold in a meat matrix is
not established. There are reasons to believe that the recommended
addition of succinate (up to 0.03 mol/kg) and glutamate
(up to 0.02 mol/kg) could be identified by sensory assessors
(Baronˇ & Jaromír, 2012; Byrne, Brediea, Mottram, & Martensa,
2002). Succinate is transformed to fumarate (accepted as a food
additive as well, and has an acid taste) but even this flavour’s
threshold is not defined in a meat matrix. Oxoglutarate (produced
from glutamate) flavour is not well described in the literature.ion
