The dissimilarities between the three leek types could be explained by their genetic background, but because of their different harvest times, stress factors such vra temperature, solar radiation, pathogens etc.
Chapter 6 elucidated the difference between leek and some of its related Allium species with regard to the antioxidant properties. In other projects Wikimedia Commons Wikispecies. Garlic Is porrjm Good as Ten Mothers documentary. Sweet pea, Lathyrus odoratus ‘Cupani’, with Leeks, Allium ampeloprasum var.
Although air-drying was the best drying technique in retaining the antioxidant capacity and polyphenols, air-drying resulted in high losses of the ACSOs compared to freeze-drying. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. These results indicated the nutritional relevance of fermentation, which can be a promising stabilisation technique for leek. The results of Chapter 9 demonstrate the higher antioxidant capacity and polyphenol content upon fermentation especially in the green leaves.
A slight increase in isoalliin level could be observed after a cool storage period. An obvious increase could be observed in the antioxidant capacity of the steamed green leaves.

Similarly, air-drying resulted in the highest total phenolic content compared with freeze-drying, while freeze-dried and refractance window dried samples exhibited equal amounts of polyphenols. Besides their economic importance, they are a source of several bioactive or health-promoting compounds including 4 important chemical groups that have perceived porrrum to human health, i.
This information can help to stimulate innovation in leek breeding, production, marketing and the consumption pattern of leek. Allium ampeloprasum is regarded as native to all the countries bordering on the BlackAdriaticameloprasum Mediterranean Seas from Portugal to Egypt to Romania.
