2025
Silvana Paola Fernandez | Roxana Elizabeth González
This work focused on the evaluation of nine clones of fresh garlic and its aged product, black garlic, and the comparison of their nutritional qualities, bioactive compounds, antioxidant activities, and the correlation among these traits. The results showed that the moisture content material of black garlic was reduced, while the crude protein, crude fiber, crude ash, and carbohydrate contents were considerably improved. Black garlic had a higher total phenolic content than fresh garlic and four to nine times more antioxidant activity. Hydroxycinnamic acid derivates were the main phenolic acids found in both fresh and black garlic. The antioxidant activity was correlated with polyphenol content and pungency levels. Finally, recommendations about the most suitable clones for black garlic production were made. These findings highlight the need for the consideration of garlic clones in both dietary and therapeutic contexts.
