Effect of Ganoderma lucidum water extract on flavor volatiles and quality characteristics of set-type yogurt

This study investigated the effects of several concentrations of Ganoderma lucidum water extract (GLWE) (0, 0.5, 1.0, and 1.5 %) on set-type yogurt's flavor volatiles as well as the physicochemical, textural, and antioxidant activities of the yogurt during storage. The HS-SPME-GC-MS investigation found that adding GLWE increased the amount of flavor volatiles in yogurt, which improved the quality of flavor volatiles produced by the yogurt. The yogurt's water holding capacity, syneresis, color, and texture all showed optimum values at a 0.5 % GLWE concentration, and its total number of flavor volatiles reached 43. To sum up, the incorporation of GLWE at a 0.5 % concentration promotes the development of superior flavor volatiles in yogurt and enhances its qualitative attributes in contrast to the control group.
