Special Issue Information

Dear Colleagues,

In recent years, scientific and technological advances in food processing have significantly contributed to the growing interest in the health-promoting potential of functional foods. These products, formulated not only to meet nutritional needs but also to deliver physiological benefits, are increasingly recognized for their role in preventing and managing chronic diseases. A wide variety of bioactive compounds—such as polyphenols, peptides, carotenoids, terpenes, and alkaloids—can be incorporated into food matrices using innovative technologies that enhance their stability, bioavailability, and efficacy.

The development of functional foods is closely linked to innovations in food technology, including novel extraction methods, advanced encapsulation systems, and sustainable processing techniques. These technologies facilitate the recovery and application of bioactive ingredients from diverse natural sources, such as plants, marine organisms, and agro-industrial by-products. Moreover, improvements in analytical tools and bioactivity assays have enabled a deeper understanding of the mechanisms by which these compounds exert antioxidant, anti-inflammatory, antimicrobial, and other health-related effects.

This Special Issue aims to bring together cutting-edge research and reviews focused on the intersection of food technology and functional ingredients. Contributions are welcome that address the sourcing, processing, characterization, and incorporation of bioactive compounds into functional food products. We especially encourage studies that explore innovative technological approaches to improve the delivery and effectiveness of these compounds, as well as their role in promoting human health.

Potential topics include but are not limited to the following:

  • Food technology innovations for functional food development;
  • Sources and extraction of bioactive food components;
  • Green and sustainable processing methods;
  • Encapsulation and delivery systems for bioactive ingredients;
  • Mechanisms of action of functional compounds;
  • Plant-derived phytochemicals and health benefits;
  • Antioxidant and antimicrobial properties;
  • Bioavailability and bioaccessibility enhancement;
  • Assessment of food bioactivity and functionality;
  • Application of bioactives in disease prevention.

Growing demand for plant-based nutraceuticals drives the need for innovative bioprocessing strategies. This study developed an integrated approach combining germination and Lactobacillus-mediated fermentation to produce a γ-aminobutyric acid (GABA)-enriched functional beverage from brown rice. Systematic screening identified an optimal rice cultivar for germination. Sequential enzymatic liquefaction and saccharification were optimized to generate a suitable hydrolysate. Screening of 13 probiotic strains revealed that a 10-strain Lactobacillus–Bifidobacterium consortium maximized GABA synthesis (12.2 mg/100 g). Fermentation parameters were optimized to 0.25% monosodium glutamate, 4% inoculum, 10 μmol/L pyridoxine hydrochloride, 37 °C, and 24 h. The resulting beverage achieved significantly elevated GABA concentrations while exhibiting low fat (0.2 g/100 g), reduced caloric content (233.6 kJ/100 g), and high viable probiotic counts (2 × 108 CFU/g). This strategy demonstrates significant potential for the scalable production of multifunctional, plant-based nutraceuticals with targeted bioactive components. Full article
