Title
Storage of Yarrowia lipolytica lipase after spray-drying in the presence of additives
Abstract

Lipase from Yarrowia lipolytica is an enzyme that presents numerous potentialities for biotechnological applications. This work describes the development of powders obtained by atomization of supernatants lipase from Y. lipolytica LGx6481. Two formulations were studied: one formulation with skim milk powder and gum arabic, and the other with maltodextrin, calcium chloride and gum arabic. After drying, powders were stored at 4 and 20 °C in aluminium hermetic bags to evaluate their stability over a period of one year. The influence of water activity and glass transition temperature (Tg) on the powder's storage were also studied.
