Probiotic films based on tamarind gum, whey, and beeswax to fortify semi-processed jicama
摘要
In recent years, there has been a growing consumer focus on health, leading to an increased demand for minimally processed functional foods. This study explores the microencapsulation of Lactiplantibacillus paraplantarum (BAL-28-ITTG) using spray drying, as well as the incorporation of the microcapsules into food films formulated with tamarind gum, whey, and beeswax. Additionally, the most effective film was applied as a coating for minimally processed jicama. L. paraplantarum (BAL-28-ITTG) was encapsulated via spray drying at temperatures of 140 °C and 150 °C, utilizing maltodextrin:gelatin blends in ratios of 19:1 (w:w) and 29:1 (w:w). The microcapsules were incorporated into films composed of whey, tamarind gum, and beeswax. A completely randomized experimental design with three replicates was employed. Results were analyzed using ANOVA (p < 0.05). The study demonstrated the survival of the microorganism after spray drying, as well as within the film during 60 d of storage at 4 °C. Incorporating the film containing encapsulated L. paraplantarum (BAL-28-ITTG) enhanced the functional properties of jicama. This study reports on the development of a probiotic film that can be utilized fortifying semi-processed foods.
