Summary
This study explored enzyme and ultrasound-assisted extraction for corn stigma polysaccharide. The combined method proved most effective for polysaccharide extraction, outperforming individual techniques.
Area of Science:
- Biochemistry
- Food Science
- Chemical Engineering
Background:
- Corn stigma polysaccharide (CSP) extraction is crucial for its applications.
- Traditional extraction methods face limitations in efficiency and yield.
- Enzyme and ultrasound-assisted extraction (EAE & UAE) offer potential improvements.
Purpose of the Study:
- To evaluate and compare enzyme treatment, ultrasound-assisted extraction (UAE), and a combined approach for CSP extraction.
- To optimize extraction conditions for each method using orthogonal experimental design.
Main Methods:
- Enzyme-assisted extraction (EAE) conditions were optimized.
- Ultrasound-assisted extraction (UAE) conditions were optimized.
- A combined EAE and UAE method was investigated and compared to individual methods.
Main Results:
- The combined EAE and UAE method demonstrated significantly higher efficiency in CSP extraction compared to EAE or UAE alone.
- Enzyme-assisted extraction showed moderate efficiency relative to the other two methods.
- Optimized conditions were determined for each extraction technique.
Conclusions:
- The combined enzyme and ultrasound-assisted extraction method is the most favorable and efficient technique for extracting corn stigma polysaccharide.
- This integrated approach offers a superior strategy for maximizing CSP yield.
