Special Issue Information

Dear Colleagues,

Green extraction technologies are transforming the method through which bioactive compounds are recovered from foods and their by-products. These compounds—such as phenolics, glucosinolates, flavonoids, and other functional ingredients—play essential roles in nutrition and disease prevention, yet many are degraded or lost during conventional processing. Environmentally friendly extraction approaches, including supercritical fluid extraction, ultrasound- and microwave-assisted extraction, and water- or solvent-free techniques, provide sustainable pathways that preserve and recover valuable molecules while reducing energy use and chemical waste. Advancements in biotransformation, analytical profiling, and high-value processing further enhance the stability, bioavailability, and functionality of recovered compounds. Understanding how different processing technologies influence the biological activity of food-derived ingredients is crucial for developing next-generation functional foods and nutraceuticals. This Special Issue highlights cutting-edge research into sustainable recovery, characterization, and application of bioactive compounds from foods and food by-products, providing a platform for innovative strategies that support health, waste reduction, and a circular food economy.

Phenolic acids are bioactive compounds in wheat (Triticum aestivum L.) that contribute to its nutritional and functional properties, yet their distribution within the kernel is uneven. This study investigated the effect of progressive pearling on phenolic acid distribution using microwave-assisted extraction (MAE) with water as a solvent. Three commercial Canada Western Red Spring wheat samples were pearled into six fractions (50–450 s), corresponding to 5–45% removal of outer kernel layers. Pearled kernels, pearled kernel flours, and pearled fractions were analyzed for total phenolic content (TPC) and individual phenolic acids using HPLC-DAD. The 10% pearled fraction (PF100) exhibited the highest TPC (9286 ± 168 µg GAE/g), confirming phenolic enrichment in the outer bran and sub-aleurone layers. Outer kernel tissues contained the highest gallic acid (1954 µg/g), whereas the endosperm retained lower levels of gallic (450 µg/g), hydroxycinnamic (122 µg/g), sinapic (87 µg/g), and ferulic (84 µg/g) acids. Both TPC and individual phenolic acids decreased progressively with increased pearling depth, indicating a clear localization gradient. MAE with water enhanced extraction efficiency compared to conventional solvent-based methods, enabling environmentally friendly recovery. These findings demonstrate that controlled pearling can be used to enrich wheat fractions in phenolic acids and optimize functional ingredient development. Full article
