Os sistemas aquosos bifásicos formados por etanol e sulfato de amônio foram mais eficientes para particionar antocianinas do açaí tipo A do que os sistemas formados por PEG e sais, uma vez que as antocianinas particionaram para uma fase e os açúcares para outra no SAB etanol/sulfato de amônio, mesmo o sistema PEG e sal tendo apresentado rendimento de antocianinas de 100% m/m. Por ser mais fácil purificar o sistema formado por PEG do que o sistema formado por etanol, o SAB etanol e sal é o mais adequado para realizar a partição das antocianinas.
Por meio da extração multiestágios foi observado que houve uma redução da concentração de açúcares na fase topo e que um estágio é o suficiente para remover 99% dos açúcares com SAB PEG 8000/sulfato de amônio e remover mais de 97% dos açúcares com SAB etanol/sulfato de amônio.
O aumento de escala mostrou-se viável para os dois sistemas, pois apresentou resultados semelhantes de rendimento de açúcares nas fases fundo tanto em escala de bancada quanto em escala maior.
As antocianinas foram identificadas por meio de UPLC-QToF porém os espectros de RMN não apresentaram picos de antocianinas mas através deles observamos que houve uma redução dos açúcares, ácidos graxos e aminoácidos após a partição do açaí tipo A por meio de sistemas aquosos bifásicos, mostrando então, a eficiência dos SABs para a partição das antocianinas.
