APPLICABILITY OF INTERESTERIFIED FORMULATIONS BASED ON MACAÚBA PULP OIL

The macaúba is a palm tree of the species Acrocomia aculeata, present in much of the national territory. It has high resistance to pests and temperature variations, as well as sustainable production. Considering that its cultivation is environmentally correct, lipid modification methods that are also sustainable increase the added value of the raw material, as is the case of enzymatic interesterification. Thus, in view of its high economic potential, the objective of this work was to study the fatty acid composition, solids profiles and consistency before and after the enzymatic interesterification reaction of macaúba pulp oil and fully hydrogenated macaúba pulp oil (hardfat). Mixtures were formulated in the ratio of 100:0 (%w/m) to 50:50 of pulp oil for hardfat (M100 - M50: simple mixtures; I100 - I50: interesterified mixtures). For the reaction, the commercial enzyme Lipozyme® TL IM was used. The lipase was conditioned and then the interesterification reaction was performed, which was performed for 6 hours at 70 °C, under vacuum and agitation at 350 rpm and addition of 4% of the already conditioned enzyme. The fatty acid composition, solid fat content (SFC) and consistency were obtained according to the methods of AOCS (2009) and Campos (2005). The fatty acid composition showed that the major fatty acid in all mixtures was oleic, followed by palmitic and linoleic acid. For SFC it was possible to notice that after enzymatic interesterification there was a decrease in SFC content compared to simple mixtures
