Assessment of the degree of secondary luminescence generated by coffee subjected to influence of a constant electric field

Abstract

The article presents the results of research on the influence of the constant electric field on the size and structure of the ultra-weak photon emission of selected coffee beans. In the research, a combination of the electric field’s impact on the material was used, consisting in the use of 1800 cycles in which the time of exposure to the electric field with a voltage of 3kV was interrupted and renewed every 10 seconds. The experimental material was coffee in the form of whole grains and coffee in the form of granules ready to be dissolved in water. The PMT Photomultiplier tube method was used to count individual photons. It has been found that it is possible to use the single photon counting method to identify the type of coffee and stimulation with a constant electric field increases the differentiation of the photon emission values.
