The apparent distribution coefficients, Kapp, of some sugar alcohols to cation-exchange resins in the sodium-ion form and with divinylbenzene (DVB) contents of 2, 4, 6, and 8% were measured at 25ºC. Assuming that the binding constant, B, of ribitol to sodium ion was zero, the swelling pressures, Π, of the resins in sodium-ion form with DVB contents of 2, 4, 6, and 8％ were estimated to be 3.2, 9.4, 12.3, and 25.7 MPa, respectively. From these Π values and Kapp values, the B values of each sugar alcohol were calculated. Because the B value is independent of the degree of cross-linking of the resin, the B values were obtained from the Kapp for resins with different DVB contents and were averaged. Erythritol and sorbitol had almost zero binding affinity to sodium ion. Among the tested sugar alcohols, the B values were in the order of xylitol > d-arabitol, l-arabitol > mannitol.

Spray drying is one of the most common and economical techniques typically employed in the microencapsulation of valuable food ingredients. Because most food core materials are generally hydrophobic, the feed solution to the spray dryer is normally an emulsion. The quality of microencapsulated powder is influenced by several operations and phenomena during spray drying, such as atomization and drying kinetics of the droplets into solid particles. In this review, selected research on the drying operations conducted over the last ten years as well as the properties of the produced powder is discussed. The items specifically reviewed are the spraying of uniform droplets, the breakage of emulsion droplets during atomization, simulation of drying a droplet by the reaction engineering approach, the storage stability of core ingredients, estimation of the surface-oil content, and measurement of the encapsulation state of the core ingredient in the dry particles by confocal laser scanning microscopy.
