Hydrocolloids as Carrier Agents: The Key to Preserving Bioactive Compounds During Drying

The statement that hydrocolloids play an important role as carrier agents that help entrap and protect bioactive compounds, especially antioxidants and phenolic compounds, from degradation during drying is broadly correct. However, if you are citing Fauziyah et al. (2022), you should specify that the hydrocolloid in question is maltodextrin (MD), not all hydrocolloids in general .

Which hydrocolloid?

• In the work of Fauziyah et al. (2022), maltodextrin (MD) was studied as a hydrocolloid and carrier agent, together with egg albumen as a foaming agent, to produce tapai (fermented black glutinous rice) powder via foam-mat freeze drying .
• Evidence from the abstract and available data shows that increasing the concentration of MD improved the retention of bioactive compounds such as and , even though adding a carrier agent sometimes reduced the absolute levels of certain compound groups compared to some conditions .
