Assessing the use of arabic gum as a drying adjuvant for powdered shrimp obtained using a spray dryer

Abstract The aim of this study was to find a new method to improve shrimp availability in the culinary and food industry, especially for products in which the flavour of shrimp must be preserved, such as sauces, seasonings, dehydrated soups, and snacks. The approach involved the use of arabic gum as a drying adjuvant on powdered shrimp obtained by spray drying. The effects of the arabic gum on the physicochemical characteristics of the powdered shrimp were then evaluated. The fresh shrimp was processed using the following steps: washing, pre-baking, cephalothorax elimination, and grinding of the abdomen in a blender. Arabic gum was added to the shrimp paste at concentrations of 2%, 4%, and 8% and dehydrated in a spray dryer with input temperatures of 120 ºC and 150 ºC. The chemical, physical, and physicochemical characteristics of to cite in the article page. the control treatment, the addition of arabic gum did not cause any significant alterations to the chemical, physical, and physicochemical characteristics. The temperature increase from 120 ºC to 150 ºC in the control samples had no significant effect (p ≤ 0.05) on the moisture of the product. The input temperature of 120 ºC was found to be the most efficient for drying the shrimp, given that the final product had a high protein content.
