Background: Guacamole is a sauce or dressing composed of avocado pulp and other ingredients. Guacamole powder is an important advance in the generation of value added for the avocado chain, as it is an alternative product with the potential to be used by the final consumer. Objectives: The aim of this study was to standardize the spray drying process for guacamole powder using the response surface methodology. Methods: Four independent variables were taken into account for the experiment design: atomizing disk speed (ADS), air inlet temperature (AIT), air outlet temperature (AOT) and vacuum pressure (VP). In addition, the following dependent variables were considered: water activity (a w ), moisture (Xw), solubility (S), hygroscopicity (H), color (L
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
