Summary
Optimizing drying parameters for fingerroot (Boesenbergia rotunda) extract preserves phenolic compounds and flavonoids. Maltodextrin concentration and outlet temperature significantly impact extract quality and antioxidant activity.
Area of Science:
- Food Science and Technology
- Natural Product Chemistry
- Biotechnology
Background:
- Fingerroot (Boesenbergia rotunda) is a medicinal plant rich in bioactive compounds.
- Drying processes significantly influence the stability and quality of plant extracts.
- Optimizing drying parameters is crucial for maximizing the yield and efficacy of bioactive compounds.
Purpose of the Study:
- To investigate the impact of drying parameters on the phenolic compounds, flavonoids, and antioxidant activity of fingerroot extract.
- To determine the optimal drying conditions for fingerroot extract using response surface methodology (RSM) and a Box-Behnken design.
- To develop mathematical models for predicting the quality attributes of fingerroot extract based on drying parameters.
Main Methods:
- Fingerroot extract was prepared and subjected to drying under varying conditions.
- Box-Behnken design was used to study the effects of maltodextrin concentration, inlet temperature, and outlet temperature.
- Total phenolic content (TPC), total flavonoid content (TF), and antioxidant activity (DPPH, FRAP assays) were measured.
- Statistical analysis, including stepwise regression, was employed to analyze the data.
Main Results:
- Maltodextrin concentration significantly affected TPC, TF, and antioxidant activity.
- Outlet temperature significantly influenced FRAP activity.
- Optimal conditions for maximizing phenolic and flavonoid content were identified as 20% maltodextrin, 150 °C inlet temperature, and 70 °C outlet temperature.
Conclusions:
- Drying parameters, particularly maltodextrin concentration and outlet temperature, play a critical role in preserving the quality of fingerroot extract.
- The developed mathematical models accurately predict extract properties, validating the RSM approach.
- Optimized drying conditions can enhance the potential applications of fingerroot extract in food and pharmaceutical industries.
