Este estudo foi conduzido para avaliar a influência da adição de isolado proteico de soro (IPS) e inulina como materiais de parede, nas características físicas de óleo essencial de alecrim encapsulado por meio de secagem por atomização. Os tratamentos IPS/inulina (3:1) (1), IPS/inulina (1:1) (2) e IPS/inulina (1:3) (3) foram avaliados em delineamento inteiramente casualizado, com três repetições. As partículas foram classificadas como razoáveis (tratamentos 1 e 2) e ruim (tratamento 3) para fluidez e todos os tratamentos foram considerados com alta coesividade. O modelo de BET apresentou o melhor ajuste para o comportamento das isotermas de adsorção, sendo observados valores de teor de umidade na monocamada (Xm) iguais a 0,053 g.g-1, 0,070 g.g-1e 0,097 g.g-1para os tratamentos 1, 2 e 3, respectivamente. Todos os pós destes tratamentos apresentaram visivelmente estrutura física amorfa mesmo em altas atividades de água. O uso de IPS e inulina como materiais encapsulantes para óleo essencial de alecrim mostrou-se como uma potencial alternativa.
