Four different types of powder mixtures were prepared using food powders that are commonly used in different seasonings. The different mixtures prepared are presented in Table 1. The powders
were procured from Santa Maria AB, Gothenburg. The two binary powder mixtures used in this study have significant differences in mixability. The paprika–salt mixture produces a good mix while
the oregano–salt mixture produces a segregating mix. The oregano has a very low bulk density and large voidage which allows the salt particles to sieve through the voids producing a segregating mix. The quaternary mixtures were formulated such that one is better mixing in nature compared to the other. One quaternary mix consisted of onion powder and black pepper in addition to paprika and salt which were considered as well mixing powders due to their similar bulk densities (Table 2). In the other quaternary mix, the onion was replaced by oregano and this resulted in a mix that had a segregation tendency.
