Absztrakt (kivonat)
Onion (Allium cepa L.) is one of the most important vegetables plants cultivated and consumed worldwide, being appreciated both for its culinary role and for its health benefits. The specialized literature shows that onion has a high nutritional value, being a source of vitamins, minerals, dietary fiber, simple carbohydrates and bioactive compounds (flavonoids, polyphenols, sulfur compounds). The red variety is distinguished by a higher content of anthocyanin pigments and flavonoids, which give it superior antioxidant properties and a sweeter taste than white onion. The aim of this work is to evaluate the basic nutritional composition (proximate composition) of a red onion assortment sold in local agri-food markets. Preliminary determinations of moisture, ash, protein, lipid, fiber and carbohydrate content revealed a significant contribution of carbohydrates and fiber, complemented by a reduced amount of protein and lipid. The results obtained: 10.12-11.06% moisture, 3.38-3.87% ash, 2.62-3.47% protein, 1.51-2.04% fat, 6.49- 7.22% fibers, and 72.48-75.31% carbohydrates propose the use of red onion powder as a natural additive in food with added value or as an alternative source in animal feed ingredients. The results confirm that red onion is a valuable food due to its basic composition and can contribute to maintaining a balanced and healthy diet.
