“…Nonetheless, in recent years, there has been increased recognition of food bio-residues as sources of phenolic compounds, notably, horticultural residues, which encompass all the discarded parts of fruits and vegetables during the different stages of the food supply chain [8,37]. Accordingly, polyphenols have already been identified from the main by-products generated in powerful agri-food manufacturing industries, which include apple pomace, banana peel, coffee pulp and spent coffee grain, grape skins, stems and seeds, olive oil mill, onion skin, and rice bran, to name but a few [38]. On top of that, the use and valorization of agri-food bio-residues as polyphenol sources to be transformed into added-value products emerges as a sustainable circular economy strategy, contributing to the minimization of environmental constrains triggered by food waste disposal, as to the attainment of economic and social benefits [37,39,40].…”

“…The particular nature and functionality of phenolic compounds has captured the attention of nutritionists, researchers, and manufacturers in various industrial sectors. In particular, the focus has been centered on the potent antioxidant properties of polyphenols and their preventive role in various non-communicable diseases related to oxidative stress, such as metabolic syndrome and diabetes, cardiovascular diseases, neurodegenerative disorders, or cancer [14,38]. In such a way, polyphenols serve as potent antioxidants in a multitude of chemical oxidation systems.…”

“…Further to this, other biological activities have been described in numerous in vitro and in vivo assays, providing anti-inflammatory, anti-hypertensive, antibacterial, antiproliferative, and neuroprotective activity, only to mention a few [14,38,42,43]. This has precipitated a myriad of intended utilizations spanning a diverse array of industrial domains, encompassing pharmaceuticals, agri-food, nutraceutical, cosmetics, and textiles.…”

Alzheimer’s Disease (AD), a prevalent neurodegenerative disorder, is the primary cause of dementia. Despite significant advancements in neuroscience, a definitive cure or treatment for this debilitating disease remains elusive. A notable characteristic of AD is oxidative stress, which has been identified as a potential therapeutic target. Polyphenols, secondary metabolites of plant origin, have attracted attention due to their potent antioxidant properties. Epidemiological studies suggest a correlation between the consumption of polyphenol-rich foods and the prevention of chronic diseases, including neurodegenerative disorders, which underscores the potential of polyphenols as a therapeutic strategy in AD management. Hence, this comprehensive review focuses on the diverse roles of polyphenols in AD, with a particular emphasis on neuroprotective potential. Scopus, ScienceDirect, and Google Scholar were used as leading databases for study selection, from 2018 to late March 2024. Analytical chemistry serves as a crucial tool for characterizing polyphenols, with a nuanced exploration of their extraction methods from various sources, often employing chemometric techniques for a holistic interpretation of the advances in this field. Moreover, this review examines current in vitro and in vivo research, aiming to enhance the understanding of polyphenols’ role in AD, and providing valuable insights for forthcoming approaches in this context.

“…Moreover, dietary fibre and phenolic compounds have been shown to stimulate the growth of beneficial microorganisms, especially lactic acid bacteria and other probiotics. Thus, bioactive compounds present in the waste of the citrus industry emerge as potential prebiotic ingredients [ 9 ]. These compounds could also have applications in food stabilisation because they help inhibit oxidation (lipid and protein) and the growth of pathogenic and deteriorating bacteria in the food supply [ 10 ].…”

The large amount of waste generated by the orange juice industry has sparked the interest of many researchers in incorporating recycling systems and following a much more sustainable circular economy model. This work proposes the valorization of the co-product generated in the orange juice extraction industry after freeze-drying for its subsequent reuse as a natural ingredient in the food industry. In addition, the possible protective effect of gum Arabic and corn starch esterified with octenyl succinic groups, in proportions optimised in previous studies 0.25 and 0.45 g/g orange co-product dry solutes, on the main bioactive compounds of orange peel during the freeze-drying process has been studied. The samples were characterised for their content of vitamin C (ascorbic and dehydroascorbic acids), flavonoids (hesperidin and narirutin), total phenols and total carotenoids, as well as their antioxidant capacity (DPPH and FRAP assays). In addition, samples were digested, mimicking the human enzymatic oral gastro-intestinal digestion process, and the bioaccessibility of the bioactive compounds was evaluated. It was observed that the addition of both biopolymers improved the stability of the hydrophilic compounds during freeze-drying. This conservative effect was more remarkable for higher biopolymer concentrations. However, no protective effect on carotenoid compounds was observed. This trend was reflected in the antioxidant activity of the different samples. In addition, the incorporation of biopolymers improved the bioaccessibility of the bioactive compounds studied. In conclusion, the results supported the feasibility of the freeze-dried orange juice co-product as a natural, sustainable source of health-promoting compounds.

PurposeThe waste generated in the process of obtaining orange juice (J) may be used as a natural source of bioactive compounds, thus contributing to the profitability and sustainability of the process. To offer orange J as a dried matter would contribute to the integral valorisation of the J waste and also may expand the field of application.Design/methodology/approachTo find out whether the JW matrix protects the bioactive compounds, the study compares the behaviour of the extracts of the compounds against drying with that resulting from drying the JW for further extraction. Dehydration was carried out at 25 or 50 C and gum Arabic (GA) and bamboo fibre (BF) were used as stabilising biopolymers (Bp). Vitamin C (VC) (L-ascorbic and L-dehydroascorbic acids [AA and DHAA, respectively]) and hesperidin (HES) were analysed before and after the drying.FindingsThe results suggest that to dry the JW gives a higher yield of bioactive compounds, which are also more stable, than when the extract is dried. Furthermore, both the higher temperature and the presence of the Bp favour the extraction of both VC and HES. In this way, all the waste from the orange J-processing industries is converted into a high-value product to be used for cosmeceutical or nutraceutical purposes and also as an ingredient for human food.Social implicationsThe utilisation of organic waste for use in human food, but also in other sectors, is part of the new economic model that aims to do away with the concept of waste as people know it, focussing on a new paradigm in which each resource is a nutrient for nature, industry or society.Originality/valueThe results suggest that to dry the waste gives a higher yield of bioactive compounds, which are also more stable, than when the extract is dried. Furthermore, both the higher temperature and the presence of the Bp favour the extraction of both VC and HES. In that way, all the waste from the orange J-processing industries are converted into a high-value product to be used for cosmeceutical or nutraceutical purposes and also as an ingredient for human food.
