Effects of hydrocolloids on the qualities of pureed banana inflorescences prepared for individuals with dysphagia

This research aimed to develop banana inflorescence purees and the recipes suitable for individuals with dysphagia. The effects of hydrocolloids (modified tapioca starch; MTS, gum acacia; GA, xanthan gum; XG, carboxymethyl cellulose; CMC, gelatin; GEL) and freeze-thaw cycles (first and second cycle) on the qualities of purees were investigated. Banana inflorescences served as a good choice for preparation of purees that complied to “Level 4 Pureed Food for Adults” as examined by the International Dysphagia Diet Standardization Initiative (IDDSI) methods. During the freeze-thaw cycles, the qualities of the purees degraded. The control sample (puree without hydrocolloid) failed the IDDSI tests when subjected to the second freeze-thaw cycle. Utilizing XG and CMC enhanced the quality and extended the shelf life. However, the effects of hydrocolloids were dependent on types and concentrations used. Some hydrocolloids, such as GA and GEL, have been discovered to be unsuitable. The recipes, including Massaman curry with chicken, Tom-yum soup, and galangal coconut soup with chicken, were successfully prepared from pureed banana inflorescences (with XG). All recipes adhered to the IDDSI guidelines for “Level 3 Liquidized Food for Adults”. The finding in this study demonstrated the balance between safety and palatability of purees specially prepared as dysphagia diets.
