| dc.abstract.en | Probiotic bacteria confer a range of health benefits and are a focus of a growing number of studies. One of the main issues is their stability during drying and storage, which is why techniques, such as fluid bed drying and coating or treatment with stress factors during culturing, are utilized. The methods of the evaluation of probiotic viability and quality are, however, lacking and we need a way of distinguishing between different subpopulations of probiotic bacteria. To address this issue, imaging flow cytometry (IFC) has been utilized to assess cells after simulated in vitro digestion of dried and coated preparations treated with pH stress and heat shock. Samples were analyzed fresh and after 12 months of storage using RedoxSensor green and propidium iodide dyes to assess metabolic activity and cell membrane integrity of the cells. The results were then used to design a drying process on an industrial scale and evaluate the economic factors in the SuperPro Designer v13 software. Based on the number of biologically active and beneficial cells obtained utilizing tested methods, the coating process and treatment with heat shock and pH stress have been the most effective and up to 10 times cheaper to produce than only by drying. Additionally, samples after 12 months of storage have shown an increase in the proportion of cells with intermediate metabolic activity and small amounts of cell membrane damage, which are still viable in probiotic products. This subpopulation of bacteria can still be considered live in probiotic products but is not necessarily effectively detected by pour plate counts. | |
