“…Several types of blenders and homogenizers and many sizes and shapes of containers have been used in emulsion preparation (Tomberg and Hermansson, 1977; Pearce and Kinsella, 1978; Johnson et al, 1977;Tsai et al, 1970). The valve homogenizer has been used widely (Tomberg and Hermansson, 1977;Berger, 1976;Titus et al, 1968;Klotzek and Leeder, 1966;Sherman, 1965) whereas few emulsion studies have been conducted with sonicators (Tomberg and Hermansson, 1977; Smith and Dairiki, 1975;Higgins and Skanen, 1972).…”
