Special Issue Information

Dear Colleagues,

"Nutraceuticals" refer to any product derived from food sources with additional health benefits, in addition to the basic nutritional value found in food. They are a group of products representing more than food but less than pharmaceuticals, and may be considered "a food or part of a food, which provides medical or health benefits, including the prevention and/or treatment of disease" (Stephen L. De Felice, 1989). Recently, research on nutraceuticals has become a hot topic due to their intrinsic properties, e.g., nutritional value potential, safety, affordability and multiple therapeutic effects. Nutraceuticals are gaining researchers’ interest as an alternative or supplemental treatment along with pharmaceuticals to aid in the prevention and treatment of a wide range of diseases. This therapeutic potential is provided by the high content of bioactive compounds, derived from natural sources with high biocompatibility and physiological benefits, able to play an important role in the body’s various biological processes, such as reducing the excess of free radicals, cell renewal, which delay the aging process or support body function and integrity, the provision of protection from chronic diseases and can improve the health naturally and overall life quality. A key advantage of nutraceuticals is their natural source; hence, the chemical grouping and categories include nutrients (fats, carbohydrates, proteins, vitamins and minerals), dietary fiber, antioxidants, inducers of beneficial enzyme activities, prebiotics and probiotics, dietary supplements, herbal products, processed foods (cereals, soups and beverages), fortified dairy products, fortified cereals, genetically engineered “designer” foods, etc. The process design of nutraceuticals is a crucial step as specific delivery systems are greatly needed to protect the nutraceuticals from the harsh conditions of the gastrointestinal tract along with the enhancement of their efficacy. Optimized nutraceuticals and tailored delivery systems can supply the human body with necessary nutrients, ensuring rapid repair and regeneration. Another fundamental aspect is the safety of these products. Potential interactions with conventional drugs present the risk of side effects, such as allergic reactions or even toxicity, depending on the dose. Security concerns request the traceability of all nutraceuticals, herbs and foods, not only for quality control, but also to prevent the introduction of chemical and microbiological hazards as counterfeiting agents.

The proposed topic for the Special Issue "Process Design, Analysis and Medicinal Importance of Nutraceuticals" is multidisciplinary; hence, we suggest an approach from various directions of nutraceuticals research, process design, obtaining and analysis methods, key molecule bioactivities determination, with emphasis on the role of bioactive compounds found in nutraceuticals as pharmaceutical alternatives, in dietary supplements, products derived from food sources that provide extra health benefits in addition to the basic nutritional value found in foods, herbal and food ingredients or functional foods as nutraceuticals, claiming to have physiological benefits, prevent chronic diseases, improve health, have antioxidant potential, delay the aging process, support the structure or function of the body and increase life expectancy.

Contributions to this Special Issue, both in the form of original research or review articles, may cover all aspects of nutraceutical research; studies with multidisciplinary input, offering new methodologies, biotechnology, innovative products, biomedical applications or insights, are particularly welcome.

Thanks to the open access platform offered by this Special Issue of Processes, researchers are able to share their investigations and findings in this promising field, increase their visibility and chances to interact with potential nutraceutical industries and production systems.

This study aimed to evaluate the hypoglycemic potential, antioxidant activity and prebiotic activity of a hydroalcoholic extract of blueberry pomace (BP), an aqueous extract of chia seeds (CS) and a novel combination of BP–CS extracts (BCM) for further use as ingredient of functional food. Spectrometric and HPLC analyses were used to characterize the total phenolic and flavonoid content and composition of BP, while CS was analyzed for total carbohydrate content. Data showed that the BCM mixture exerted an inhibition of α-amylase activity, which was 1.36 times higher than that of BP and 1.25 higher than CS extract. The mixture also showed better scavenging activity of free DPPH radicals than individual extracts, and had an IC50 value of 603.12 µg/mL. In vitro testing indicated that both serum- and colon-reaching products of simulated intestinal digestion of BCM presented the capacity to protect Caco-2 intestinal cells against oxidative stress by inhibition of reactive oxygen species production. In addition, the colon-reaching product of BCM digestion had the capacity to significantly (p < 0.05) stimulate the growth of Lactobacillus rhamnosus and Lactobacillus acidophilus, revealing a prebiotic potential. All these results indicated that improved biological activity of the novel combination of BP and CS extracts could be due to the synergistic action of constituents. The combination is recommended for further testing and the development of novel functional food for controlling type 2 diabetes and gastrointestinal conditions. Full article

Green synthesis of metal nanoparticles in nanosized form has acquired great interest in the area of nanomedicine as an environmentally friendly and cost-effective alternative compared to other chemical and physical methods. This study deals with the eco-friendly green synthesis of titanium dioxide nanoparticles (TiO2 NPs) utilizing Juniperus phoenicea leaf extract and their characterization. The biosynthesis of TiO2 NPs was completed in 3 h and confirmed by UV-Vis spectroscopy, a strong band at 205.4 nm distinctly revealed the formation of NPs. Transmissions electron microscopy (TEM) analysis showed the synthesized TiO2 NPs are spherical in shape, with a diameter in a range of 10–30 nm. The XRD major peak at 27.1° congruent with the (110) lattice plane of tetragonal rutile TiO2 phase. Dynamic light scattering (DLS) analysis revealed synthesized TiO2 NPs average particle size (hydrodynamic diameter) of (74.8 ± 0.649) nm. Fourier transmission infrared (FTIR) revealed the bioactive components present in the leaf extract, which act as reducing and capping agents. The antimicrobial efficacy of synthesized TiO2NPs against, Staphylococcus aureus, and Bacillus subtilis (Gram-positive), Escherichia coli and Klebsiella pneumoniae (Gram-negative), Yeast strain (Saccharomyces cerevisiae) and fungi (Aspergillus niger, and Penicillium digitatum) assayed by a disc diffusion method. TiO2NPs inhibited all tested strains by mean inhibition zone (MIZ), which ranged from the lowest 15.7 ± 0.45 mm against K. pneumoniae to the highest 30.3 ± 0.25 against Aspergillus niger. The lowest minimum inhibitory concentration (MIC) and bactericidal (MBC) values were 20 μL/mL and 40 μL/mL of TiO2NPs were observed against Asp. niger. Moreover, it showed significant inhibitory activity against human ovarian adenocarcinoma cells with IC50 = 50.13 ± 1.65 µg/mL. The findings concluded that biosynthesized TiO2 NPs using Juniperus phoenicea leaf extract can be used in medicine as curative agents according to their in vitro antibacterial, antifungal, and cytotoxic activities.
