Abstract
Optimization of shiitake mushroom vacuum drying process was the objective of this research In order to produce dried sample with satisfactory shelf life response surface methodology was used Vacuum drying used to accomplish the task was previously described by the authors The samples were dried at 46–74 °C and 20–580 mbar As quality indicators of dried product total solids water activity total phenolics IC50 and total color change were used Response surface methodology resulted in optimal conditions of 571 °C and 100 mbar In order to verify predictions and adequacy of the secondorder polynomial models separate validation experiments were conducted at optimum conditions The predicted amount of total solids was 8540 while aw value was 0615The authors would like to thank the Ministry of Education Science and Technological Development Republic of Serbia for financial support Project No TR31044 Installation and development of the drying device were performed in cooperation with “Kovačević inženjering” DOO Banatski Karlovac Serbia
