Summary
Lycopene, a potent antioxidant, is found in tomatoes and rosehips. Processing increases lycopene bioavailability, with rosehip showing significant amounts and a unique isomer pattern.
Area of Science:
- Nutritional Science
- Food Chemistry
Background:
- Lycopene is a powerful antioxidant and singlet oxygen quencher, primarily sourced from tomatoes in the human diet.
- Food processing methods can enhance the bioavailability of lycopene by releasing it from protein complexes.
Purpose of the Study:
- To investigate the lycopene content and isomer profile in rosehip.
- To compare the bioavailability of lycopene from different dietary sources.
Main Methods:
- Quantification of lycopene content in rosehip using established analytical techniques.
- Analysis of lycopene isomer patterns in rosehip extracts.
Main Results:
- Rosehip exhibits high lycopene concentrations, ranging from 12.9 to 35.2 mg/100 g.
- An unexpected and distinct isomer pattern of lycopene was identified in rosehip.
Conclusions:
- Rosehip represents a significant dietary source of lycopene.
- The unique isomer profile of lycopene in rosehip warrants further investigation regarding its bioavailability and biological activity.
