Guacamole Powder: Standardization of the Spray Drying Process

Abstract: 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… Show more

“…The avocado suspension was mixed with maltodextrin in a proportion of 1:5 w:w solids ratio, immediately after the addition of 0.22 g lyophilized ginger extract (0.22 g), and the pH 4.5 was adjusted with a lemon juice solution (approximately 1 ml). The suspension was homogenized and immediately afterward was subjected to spray dryer (BÜCHI Mini Spray Dryer brand, model B‐290) using a two‐way nozzle (0.7 mm) and different inlet temperatures (160, 170, and 180°C) and outlet temperature of 90 ± 5°C (Estrada et al, 2017), at a feed flow of 5 ml/min and a pressure of 230 mmHg, protecting it from light during the drying process. The feed solution was continuously stirred using a magnetic stirrer to avoid phase separation.…”

“…La S se determinó según la metodología de Estrada et al, (2017) modificado, dispersando 0.5 g de polvo en 50 mL de agua destilada. La H (g H2O/100 g muestra) se determinó por el método gravimétrico de isotermas de sorción, considerando un ambiente controlado a 25°C y humedad relativa del 68.9% (solución sobresaturada de KI) (Estrada et al, 2017;Santhalakshmy et al, 2015). La Hu se determinó como el tiempo requerido para que 1 g de muestra penetre totalmente la superficie de un volumen de 100 mL de agua a 25 °C (Santhalakshmy et al, 2015) 2020).…”

“…2012). La S se determinó según la metodología descrita por Estrada et al, (2017) modificada en la relación de relación de dilución (50 mL agua destilada /0.5 g MPUA). La H se determinó por el método gravimétrico de isotermas de sorción de agua (Muzaffar & Kumar, 2016;Santhalakshmy et al, 2015), utilizando una atmósfera de humedad relativa constante (68,9%), obtenida con una solución sobresaturada de KI a 25 °C en un matraz hermético, se expresó en g H2O/100 g. La Hu se determinó según la metodología de Machado et al (2014), definido como el tiempo de humectación para que 1 g MPUA se humedezca totalmente y desaparezca de la superficie de un volumen de 100 mL de agua a 25°C.…”
