Microencapsulation of bioactive compounds from peanut residues: stability study and application in yogurt

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Peanut skin, a byproduct of peanut processing, is a rich source of phenolic compounds (520.65 mgGAE (100 g)−1 d.b.) with strong antioxidant capacity, but which remains underutilized. The direct incorporation of phenolic extracts into dairy products is challenging, due to their instability during processing and storage and possible ...

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ (Cucumis melo L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...
