Summary: Because of their appreciable protein content apricot kernels could be used as a good source of food. However, their wide use for human or animal nutrition is dependent on their adequate detoxification. This is because apricot kernels have a strong bitter flavour that is caused by the presence of amygdalin, a toxic cyanogenic glycoside. The aim of the present work was to investigate an unusual method of detoxifying apricot kernels by soaking them in water. The method was energetically relatively inexpensive as uncrushed kernels and cold water were used. Furthermore, the use of intact kernels minimized the loss of nutritious soluble matter during the detoxification. On the basis of a simple but adequate mechanistic model, a mathematical description of the extractive detoxification of apricot kernels is proposed. The two-resistance mass transfer system is based on external film mass transfer and an effective solid diffusion. A linear equilibrium curve arises from the assumption that the concentration profile inside the solid phase can be well approximated with a second order polynomial calculation, this then leads to an analytical formulation of the mathematical model. The liquid-phase mass transfer coefficient and the internal diffusion coefficient in the kernels can be then determined. Finally, the model is used to describe extractor behaviour and predict process performance under real operation conditions.
