The correct and automatic management of a crystallization process would require the knowledge, in real‐time, of the amount of the crystals present in the magma, the supersaturation of the mother liquor, the growth kinetics etc. To solve this problem, we tried to utilize the NIR (Near Infra‐Red Spectroscopy) technique using a probe submerged in the growing magma. The first results obtained following the cooling crystallization of sucrose are presented and discussed.
