Italian research reveals medical potential in orange processing waste

Recent scientific studies have highlighted new health benefits and medical applications for oranges. Research coordinated by the CNR Institute for Bioeconomy in Florence and the University of Milan, published in the journal Biomedicines, has identified a revolutionary medical use for 'pastazzo'—the waste byproduct from processing Sicilian blood oranges.

Beyond providing essential Vitamin C, oranges contain flavonoids such as hesperidin, which offer antioxidant and anti-inflammatory properties. The fruit's fiber also supports intestinal health and helps moderate sugar absorption. Recent studies have expanded into areas such as gene expression, neurological disease prevention, and the use of biotechnology to develop healthier varieties.

In Italy, orange consumption remains high, with an estimated 30 to 32.5 kg per capita annually between 2021 and 2024. Experts suggest eating the whole fruit rather than just juice to retain essential fibers.
