Two important parameters are often neglected in the monitoring of perishable goods during transport: mould contamination of fresh food and the influence of acceleration or vibration on the quality of a product. We assert the claim that it is necessary to focus research on these two topics in the context of intelligent logistics in this opinion paper. Further, the technical possibilities for futuremeasurement systems are discussed. By measuring taste deviations, we verified the effect on the quality of beer at different vibration frequencies. The practical importance is shown by examining transport routes and market shares. The general feasibility of a mobile mould detection system is established by examining the measurement resolution of semiconductor sensors for mould-related gases. Furthermore, as an alternative solution, we present a concept for a miniaturized and automated culture-medium-based system. Although there is a lack of related research to date, new efforts canmake a vital contribution to the reduction of losses in the logistic chains for several products. © 2014 The Author(s) Published by the Royal Society.

In connection with interiors infested with mould, allergy-related diseases of the respiratory system should be given priority attention. However, not only are the medical diagnostics in this area still insufficiently standardized, but the sampling and quantification of airborne mould allergens are also highly problematical. To assess mould infestation from the health point of view, resort has been made until now to the quantification of mould concentrations and the identification of the mould species occurring. Reference is mainly made to the potential characteristics and effects described in the literature that can impair human health. The existence of a potential health hazard is therefore deduced indirectly. The present article describes an optimized method for the direct sampling and quantification of disease-inducing mould components - allergenic proteins - in the indoor and outdoor air.
