“…In general, even using raw material with different acidities, the Eversa performance was very close. In relation to the initial saponifiable matter (91-96 wt.% saponification index), the conversion of saponifiable matter to FAEEs was up to around 90%, showing the good performance of this enzyme for lowly and highly-acid raw materials, as already demonstrated with other fatty materials [1,4,7,8,10,11,13,14,19,55,[57][58][59]. For example, Miranda et al, [5] reported FAEE yields around 90 wt.% after 48 h of reaction in the presence of 6.0% water, using liquid Eversa and refined soybean oil.…”
