WEBFeb 1, 2021 · The increment of solubility of starch after milling has been observed using other types of mills where the cold watersolubility increases up to 93% using a stirring mill (Huang et al., 2007) or to 74–93% using a rollingtype ball mill (Zhang et al., 2010). Although, these solubilities were obtained after 2 and 100 h of milling, respectively.
