By a process of crystallizing raffinose under cooling, raffinose is efficiently crystallized, by continuously or intermittently circulating a solution containing raffinose, whereby temperature control can be done rapidly and accurately and laborious works for removing raffinose crystals adhered to the container are never needed because raffinose crystals are not adhered to the crystallization container under cooling, leading to the elevation of the yield, so the invention is excellent as a system for producing raffinose crystals industrially, in particular. |
