Feed and its additive dusts have a high combustion heat, which poses significant risks of dust explosions during production, thereby threatening life and property safety. Currently, premix inhibitors are widely used as explosion suppression measures. However, traditional inhibitors are inedible and cannot be added to feed dust to achieve explosion suppression. Therefore, this study focuses on the dust of DL-methionine (DLM), a primary additive in feed, and investigates the effect of self-synthesized phytic acid-cytosine (PA-CY), an edible biomass-based compound with nutritional value and environmental friendliness, on the flame propagation characteristics of DLM dust explosions. The flame propagation process was recorded through high-speed photography and visualized in a vertical pipe while calculating the flame velocity. Additionally, thermocouples were used to monitor changes in flame temperature. The results indicate that as the mass fraction of PA-CY increases, the luminosity of DLM dust explosion flames consistently decreases, severely disrupting the flame structure. After adding 20% PA-CY, there is a reduction of 50.0%, 52.2%, and 46.7% in peak velocity (from 27.66 m/s to 13.83 m/s), average velocity (from 14.39 m/s to 6.88 m/s), and peak temperature (from 1014℃ to 540℃) respectively. Moreover, when the mass fraction of PA-CY reaches 30%, ignition of the dust cannot occur indicating significant inhibitory effects provided by PA-CY.
