Abstract: We report the study of the microencapsulation processes of a protein isolate from Cordyceps militaris using spray drying technique. Maltodextrin (MD), β-cyclodextrin (β-CD) and maltodextrin mixed with β-cyclodextrin (MD:β-CD) at ratio of 1:1, 1:2 and 2:1 (weight/weight) and the ratio of protein isolate to wall material of 1:4 (weight/weight) were used as experimental variables. Physicochemical properties of microencapsulated powder, i.e., yield percentage, color value, water activity, encapsulation efficiency, solubility, chemical composition, total phenolic content, DPPH and ABTS radical activities were investigated. Protein isolates encapsulated with MD1:β-CD2 had the highest yield percentage and protein content of 73.89 % and 16.75 %. However, β-CD-encapsulated had the highest encapsulation efficiency and solubility of 89.44% and 95.67%, respectively. In addition, all treatments of microencapsulated powder had water activity, lightness (L*), redness (a*) and yellowness (b*), and total color difference (∆E*) values in the range of 0.21-0.25, 74.74-79.20, 7.32-8.65, 35.59-41.52 and 38.94-46.21, respectively. β-CD encapsulated protein isolate powder had the highest total phenolic content of 101.45 mg GAE/g sample, but MD1:β-CD2 encapsulated protein powder had the highest ABTS radical scavenging activities of 1536.49 µmol Trolox equivalent/g sample, respectively. Therefore, the protein isolate encapsulated with MD1:β-CD2 with its high yield percentage and antioxidant activity, represents an optimal microencapsulation process for Cordyceps militaris.
