Hypothesis
How does accelerated thermal treatment affect the carotenoid content and quality parameters of sweet paprika from different origins?
Conclusion
The study found that heat treatment significantly reduced carotenoid content and altered quality parameters, with Chinese paprika showing greater stability than Peruvian paprika.
Supporting Evidence
- Chinese paprika had 30% more total carotenoids than Peruvian samples before treatment.
- Heat treatment caused a 70% loss of carotenoids in Peruvian samples and 30% in Chinese samples.
- Both origins had similar carotenoid profiles, with β-carotene being the predominant carotenoid.
- The higher content of esterified carotenoids in Chinese peppers resulted in better thermal stability.
- Statistical analysis showed significant effects of origin and treatment on carotenoid content and antioxidant capacity.
Takeaway
This study looked at how heating sweet paprika affects its color and nutrients. It found that paprika from China stays better during heating than paprika from Peru.
Methodology
The study used 30 paprika samples from Peru and China, applying a heat treatment of 80 °C for 8 hours and analyzing carotenoid content, color parameters, and antioxidant capacity.
Limitations
The study did not explore the long-term effects of storage on carotenoid stability.
