The acidity of all samples were higher than the required, however, there is no regulation in Codex Alimentarius Hungaricus for buckwheat based products. This article does not include the analysis of the acidity of the buckwheat flour and mixtures; however it was determined during the experiment. Our results (buckwheat flour: 6.37 ± 0.12 °SH; silkworm powder: 12.24 ± 0.37 °SH) show that buckwheat flour and insect powder have a higher acidity than wheat flour (max. 5 °SH, (Codex Alimentarius Hungaricus, 2013), which explains the high acidity of the pasta samples.
