Effects of Allium ursinum L. Leaves and Egg Amount on Quality Attributes, Polyphenol Content, and Antioxidant Capacity of Pasta

Abstract

Pastas enriched with vegetables are premium nutritious products and their consumption can bring significant health benefits. Recent studies have reported a high content of bioavailable phytochemical compounds in Allium ursinum L.; as such, it can be used in the development of functional food products. This study involved the evaluation of 10 varieties of pasta. Five of these varieties were made from white flour and varying amounts of egg (Ctrl_1–Ctrl_5). The other five varieties (AU_1–AU_5) contained fresh shredded wild garlic leaves in equal proportions (20 g) in addition to the corresponding ingredients (white flour and egg). All pasta variants were investigated for their cooking properties and the presence of bioactive compounds and antioxidant capacity in the raw and cooked pasta. Sensory analysis was conducted on all types of cooked pasta, and results indicated that the pasta with the least quantity of eggs was the most favoured variant. Additionally, the pasta that was enhanced with wild garlic leaves received the highest rating for “overall quality”. According to our results, the optimal cooking time (OCT) increased when the quantity of eggs was raised, but when wild garlic leaves were present, OCT decreased in comparison to the control samples. A significant decrease (p < 0.05) in the cooking parameters, swelling index, and water absorption was observed in both egg pasta (Ctrl) and egg pasta enriched with A. ursinum L. (AU). However, compared to the corresponding egg pasta, the presence of wild garlic in pasta generally produced higher values in SI and WA. Pastas enriched with wild garlic are rich in polyphenols (TPh), with a content ranging from 82.44 to 94.62 µg GAE/g dw, and also exhibit antioxidant properties. The amount of total polyphenol significantly decreases (p < 0.05) during cooking varies depending on the composition of the pasta. The pasta with the highest egg content (AU_5) had the lowest loss of polyphenols, equivalent to 55.35%. Our investigations indicate that producing pasta with eggs and fresh wild garlic leaves results in a valuable food product with a good sensory score, enriched in bioactive components, with essential nutrients that maintains cooking qualities.
