Optimization of Spray Drying Conditions for Production of Barley Beer Powder

Desmond Antwi Arthur | Ren Xiaofeng

Abstract: The aim of this study was to use response surface approach to optimize spray drying operating parameters for barley beer powder manufacture. As independent variables, the spray drying operating parameters were employed, which included inlet air temperature (100-150?C), outlet air temperature (60-90?C), and carrier agent ratio. Moisture content, water activity, solubility, pH, and product yield were among the responses assessed. The independent variables had a stronger impact on all of the responses studied, according to the statistical analysis. The quadratic model's validity was tested by using the obtained optimum conditions for powder manufacturing. The results showed that 150?C inlet air temperature, 81?C outlet temperature, and 1.7 (w/w) carrier agent were the best spray drying operating parameters for producing high-quality barley beer powder. Barley beer powder with desirable features such as low moisture content, low water activity, high solubility, and high yield might be generated under these ideal conditions.
