Fundamentals of Drying of Microbiological Materials

Micro-organism inactivation during drying of small droplets or thin-layer slabs – A critical review of existing kinetics models and an appraisal of the drying rate dependent model

“…They concluded that the rate-dependence of microbial inactivation is greater when the drying condition is more severe, especially at higher drying rate conditions and also during the early stage of drying. This finding is in agreement with Kuts and Tutova (1983), who mentioned that a high drying rate negatively affects the inactivation rate, and stated that the drying rate must be considered as one of the most important parameters that influence the residual activity during drying. From the work by Li et al (2006), Eqs.…”

Drying of Biotechnological Products

“…The results of experimental investigations and theoretical assumptions concerning this drying method are discussed elsewhere [20,24,[71][72][73][74][75][76][77] and in a monograph on microbiological concentrates [19]. One of the components of the mixture is a carrier.…”

“…Finally, many known drying methods are characterized with reference to their advantages and disadvantages as applied to biotechnological products. There are still up-to-date general publications presenting the analysis of specific conditions of drying and preservation of biotechnology products used in many European countries [22][23][24][25][26][27][28][29][30], and also valuable publications that give an account of experimental results [31][32][33][34][35]. However, its structure has been preserved and the most important trends and procedures applied in drying of biotechnology products are emphasized.…”

Isolation and Characterization of Bromelain (BML) Proteases from Ananas cosmosus an asset to Cancer Chemotherapy

“…The drying air flow rate and the feed temperature were kept at 41m 3 hr -1 and 27°C, respectively. The duration of each experimental run was 90 min [11], [12], [14]. …”
