Bioactive compounds recovery by freeze concentration process …
Once the freeze concentration process is carried out at low temperatures, in general there is minimal loss of bioactive compounds, being able to produce a high-quality new product (Orellana-Palma et al., 2019, Petzold et al., 2016). However, the obtained fractions may present different behaviors and values for different components.

The Concentration Process
Up to now we have essentially been interested in the random variable c(O) and not in the stochastic process c(t). The reason is, cf. the discussion in section 3, that the models considered describe c(t) while the interesting concentration is c E (t). In the derivation we have, on the other hand, often used the stationarity of c(t), which is a stochastic process property.
