Wang and his colleagues (2017) also underpin that ultrasonically-assisted extraction (UAE) is been proven to be a more economical and environmental-friendly process with higher efficiency and less cost compared with conventional heating extraction (CHE).
UWang nozakwabo (2017) baphinde bagcizelela ukuthi isizinda esisizwa nge-ultrasonically-assisted (UAE) kufakazelwe ukuthi siyinkqubo eyonga kakhulu futhi evikela imvelo ngokusebenza kahle kakhulu futhi kubiza kancane uma kuqhathaniswa nesizinda esivamile sokushisa (CHE).
