Foliar iron and zinc applications mitigate salinity stress in Althaea officinalis L.: Effects on yield, antioxidant responses, and mineral composition

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Foliar application of micronutrients may help alleviate the adverse effects of salinity on crop plants. This study evaluated the effects of foliar‐applied iron (Fe) and zinc (Zn) on Althaea officinalis L. grown under saline conditions. A factorial experiment was conducted using three salinity levels (0, 4, and 8 dS m−1, imposed with NaCl) and ...

Assessment of Phytochemical Compounds and Antioxidant Potential of West Indian Avocado (Persea americana) Peel From Substandard‐Quality Fruits as a Valorisation Strategy

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
West Indian avocado peels discarded because of low‐commercial‐quality were evaluated as a source of bioactive compounds. Avocado peels contained high levels of phenolic compounds and showed strong antioxidant capacity. These results support avocado peel valorisation within functional foods, circular and sustainable food systems.

Harvest Time Influences Inulin and Phenolic Accumulation of Globe Artichoke (Cynara cardunculus L.)

Food Science &Nutrition, Volume 14, Issue 11, November 2026.
Globe artichoke heart fructans were positively correlated with solar radiation exposure while phenolics were negatively correlated. Browning was positively correlated with phenolics, especially dicaffeoylquinic acid isomer. Artichoke hearts with high phenolic contents had higher CIE b* values (yellowness).
