Special Issue Information

Dear Colleagues,

Food delivers nutrients that are essential for human life. Recently, there has been a remarkable rise in the production of processed foods and alterations in lifestyle. Worldwide, plant food is being increasing consumed due to several metabolic disorders linked to some diets and compounds involved in health improvement and disease protection. The World Health Organization recommends high intakes of plant-based foods, which includes eating at least 400 g of fruits and vegetables daily.  Whole grains, vegetables, and fruits have been associated with bioactive non-nutritional chemical components commonly known as phytochemicals. Plant food contains minerals that are necessary components of a healthy human diet, in addition to primary and secondary metabolites. Secondary metabolites are not only crucial for the development or functioning of plants, but present bioactive constituents that influence nutrition and possess health-promoting properties. The wide variety of secondary metabolites present in plant sources include dietary fiber, oligosaccharides, glycoalkaloids, polyphenols, carotenoids, biogenic amines, fatty acids, peptides and vitamins, which have been confirmed to possess antioxidative, anti-inflammatory, or immunomodulatory properties, or improve intestinal barrier functioning, which contributes to their ability to mitigate the pathological impact of some human diseases. Plants give us vegetables, fruits, cereals and pulses. Plants also give us coffee, tea, sugar, oil and spices. We are able to source food for humans from different parts of plants, including the roots, leaves, stems, flowers and fruits.

There is an urgent need for studies to determine the presence, amount, and biological properties and health effects for humans of bioactive compounds from plant food. We encourage the submission of manuscripts to this Special Issue that address the characterization, profile composition, quantitation and health effects of bioactive compounds found in plant food via the development of innovative strategies and by means of consolidated analytical and biological methods.

Sustainable and environmentally friendly extraction methods for natural bioactive compounds are gaining significant attention in the food, beverage, and nutraceutical industries. Among these bioactive compounds, anthocyanins, which are potent antioxidants, have garnered particular interest due to their health-promoting properties. Banana inflorescence, an underutilized agricultural by-product, is a rich source of bioactive compounds. However, the extraction of bioactive compounds is often energy-intensive, which raises concerns about environmental sustainability. Accelerated solvent extraction (ASE) has emerged as an efficient and less energy-consuming method for isolating these compounds. This study investigates the optimization of ASE for the extraction of phenolic compounds, including anthocyanins, from fresh banana inflorescence. The effect of extraction parameters, including temperature (60, 80, and 100 °C), solvent type (water, ethanol, methanol), and solvent composition (50% ethanol + 50% water, 75% ethanol + 25% water, 100% ethanol, 50% methanol + 50% water, 75% methanol + 25% water, 100% methanol, water), on the extraction efficiency was evaluated. The results showed that the most effective extraction conditions were 75% methanol + 25% water at 100 °C, yielding the highest concentrations of total phenolics (1239.58 ± 20.83 mg/100 g), antioxidant activity (2.21 ± 0.03 mg/mL), and anthocyanins (22.82 mg ± 1.91/100 g). LC-UV-MS analysis revealed three primary anthocyanidins: cyanidin-3-rutinoside, delphinidin-3-rutinoside, and petunidin-3-rutinoside. These findings suggest that banana inflorescence, an agricultural waste product, can be efficiently utilized as a source of bioactive compounds using ASE, contributing to sustainable practices in the food and nutraceutical industries. The optimized extraction process provides a promising approach for the valorization of banana inflorescence, enhancing its potential as a functional ingredient in food products. Full article
