1. Emulsifying akụrụngwa
Ka ọ dị ugbu a, e nwere ụdị igwe emulsifying atọ: igwe igwe emulsifying, igwe igwe colloid na homogenizer. Emulsifying igwe ụdị na Ọdịdị, arụmọrụ na size nke emulsion ahụ (dispersion) na àgwà nke emulsion (nkwụsi ike) nwere nnukwu mmekọrịta. The emulsion emepụtara site na-akpalite emulsifier nwere adịghị mma dispersibility, nnukwu na keadighi rarii ahụ, ogbenye nkwụsi ike na mfe mmetọ.
