Preparation and Characterization of Gummies Loaded with Melatonin and Lycium barbarum L.

In order to expand the application of melatonin in gel food, convenient gummies loaded with melatonin and Lycium barbarum L. were developed in this study. The comprehensive effects of gelatin dose, Lycium barbarum L. powder level and drying time on the properties of melatonin gummies were investigated by color difference analysis, texture analysis, low field NMR analysis and sensory evaluation. The results showed that the gummies containing with 0.4% Lycium barbarum L. powder, 18% gelatin, 5% carrageenan, 17.5% sorbitol, 17.5% erythritol and drying for 18 h were elastic and palatable with smooth surface. The gummies had moisture content less than 20% and melatonin retention rate of 92.0%~97.7%, and high sensory evaluation with potential practical application.
