Chapter 2 gave a brief summary concerning the current position of leek production in Belgium and abroad. In addition, the present study can give the onset to valorise the green leaves of leek, plant material which is rich in antioxidants. These species were higher in porrrum and flavonoid content, respectively. Allium ampeloprasum is a member of the onion genus Allium.

Red Creole, red onion were the species with different antioxidant properties compared to leek. Chapter 6 elucidated the difference between leek and some of its related Allium species with regard to the antioxidant properties. The dissimilarities between the three leek types could be explained by their genetic background, but because of their different harvest times, stress factors such as temperature, solar radiation, pathogens etc.


The difference between the antioxidant properties of the white shaft of the entire leek and the packaged leek was minimal, except for the lower ACSO values in packaged leek. Allium porraceum Gray Allium porrum L. These results indicated the nutritional relevance of fermentation, which can be a promising stabilisation technique for leek.

Harvest time had a clear effect on antioxidant levels, in addition to the effect of cultivar. Boiling had a negative effect on total phenolic content in the white shaft and green leaves. Allium ampeloprasum – MHNT. For the surname, see Kurrat surname. Faculty of Bioscience Engineering, Ghent, Belgium. Young leek Allium ampeloprasum var.

Retrieved from ” https: Chapter 3 described the experimental design, including the selected plant material, the sampling procedure and further sample preparation for each experiment. The green leaves of most cultivars contained a higher antioxidant capacity, ascorbate and polyphenol content, while the white shaft was rich in ACSOs and fructans.

Fermentation does not require extensive materials and is an inexpensive way to stabilise and preserve plant material such as leek. Allium porrum autum variety. Sell images Our Blog. In general, steaming seemed to be responsible for a better retention of the bioactive compounds present in leek.

Moreover, epidemiologic studies elucidated the reduction prorum the risk of prostate, colorectal, stomach and breast cancer when leek is consumed. Besides their economic importance, they are a source of several bioactive or health-promoting compounds including 4 important chemical groups that have perceived benefits to human health, i.


Harvester harvesting Leek Allium ampeloprasum var. Allium ampeloprasum has been differentiated into four cultivated vegetables, namely leekelephant garlickurrat and Persian leek. An obvious increase could be observed in the antioxidant capacity of the steamed green leaves. Faculty of Bioscience Engineering; The application of 2 alternative value-adding valorisation methods, including lactic acid fermentation and drying, were therefore investigated in Chapter 9 with regard to the retention of the antioxidant properties.

The analysis of individual polyphenols revealed again that, air-dried samples contained higher quantities of polyphenols than freeze-dried leek, while freeze-dried leek exhibited higher levels of polyphenols compared to refractance window dried samples.

The evaluation of the impact of post-harvest storage and domestic food processing on the health benefits of vegetables is also of great practical importance and was demonstrated in Chapter 7 and Chapter 8, respectively.
