Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it’s no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report in ACS’ Journal of Agricultural and Food Chemistry that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against postharvest diseases.
Sunflowers are cultivated around the world for their seeds and oil, but the flower stems — known as receptacles — are generally considered to be a waste product. Noting that this crop is particularly resistant to many plant diseases, Xiao-Dong Luo, Yun Zhao and colleagues decided to investigate whether its receptacles might contain chemical constituents responsible for this protective effect. They also wanted to find out if these compounds could be used to fend off fungal plant pathogens in fruit, as a way to avoid the toxicity and resistance associated with chemical fungicides.
