Aging is an inevitable process that is characterized by physiological deterioration and increased vulnerability to stressors. Therefore, the interest in hallmarks, mechanisms, and ways to delay or prevent aging has grown for decades. Natural plant products and their bioactive compounds have been studied as a promising strategy to overcome aging. Ginseng, a traditional herbal medicine, and its bioactive compound, the ginsenosides, have increasingly gained attention because of various pharmacological functions. This review introduces the species, useful parts, characteristics, and active components of ginseng. It primarily focuses on the bioconversion of ginsenosides through the unique steaming and drying process. More importantly, this review enumerates the antiaging mechanisms of ginseng, ginsenosides, and other bioactive compounds, highlighting their potential to extend the health span and mitigate age-related diseases based on twelve representative hallmarks of aging.

Infant food allergies have become a continually rising global health issue. There is a lack of global standardized recommendations on measures for prevention and treatment of infant food allergies because of the variations in ethnic, social, educational, and healthcare practices that affect the outcomes of research studies. Food allergies can cause mild to severe reactions and can affect social and emotional aspects of life up to the adolescent stage and are sometimes never outgrown. Maternal factors such as in utero supply of antibodies, dietary diversity, genetics, food allergen consumption during pregnancy, gut microbiota, and breastfeeding characteristics are the cornerstones of the development of an infant's immune system. In this review, we discuss how prenatal and postnatal factors affect the gut microbiota and development of an infant's immune system, and the current therapies available. The importance of food processing and education of stakeholders in the care of infants with food allergies is also discussed.

Professionals and practitioners in food science and technology navigate a minefield of challenges stemming from the convergence of science, scientific inquiry and research, and online mass and social media. Misinterpretations and politicized debates occur frequently in online media, where food- and diet-related topics have an avid following, and conflicting information or incomplete coverage may occasionally undermine public trust in the integrity of food science research from both academia and industry. Leveraging a broad landscape analysis of scientific and popular lay journal reports, we catalog a series of food science and technology topics that have been popularized in online forums, sometimes at the expense of scientific accuracy. Finally, we detail some guidelines and tools that may assist food science and technology academics, industry professionals, science publishers, and online journalists in rigorously safeguarding the integrity and credibility of research reports that reach the lay consumer through social and online media channels.

Lipids are key compounds in foods and provide energy and nutrients to the body. They are carriers of aroma and flavor compounds and contribute to structure and texture. Nutritional research has shown that positive effects on human health are derived from the intake of specific lipids. Similarly, food science research has shown that food matrix design benefits from having tailored lipid fractions with specific functions such as melting profiles, crystal structures, and oil-binding capacities. Minor constituents such as polar lipids or waxes also have valuable functional properties such as the ability to stabilize interfaces, facilitate spreadability, provide barriers, or act as organogelators. Coupled with the emergence of new feedstocks such as new plants, microbes, or insects, this has fueled a renewed interest in designing efficient, effective, and environmentally friendly processes to extract and fractionate lipids from feedstocks. Such precision-processing approaches are intended to yield not just bulk oils and fats but also specialty lipids with tailored properties. In this review article, we discuss the extraction and fractionation approaches used to obtain lipid fractions from plants, animals, or microbial fermentation, discuss their properties and functionalities, and highlight process design approaches, with a focus on sustainable extraction technologies. Recent advances in the three main steps in obtaining food lipids are highlighted: (a) crude oil manufacture; (b) refinement; and (c) fractionization. Finally, three case studies of specialty ingredients derived from such precision-processing approaches are presented.

(Poly)phenols, including flavonoids, phenolic acids, and tannins, are a diverse class of compounds found in plant-based foods and beverages. Their bioavailability has been extensively described and detailed metabolic pathways elucidated. Although some parent (poly)phenols are absorbed intact in the small intestine, most pass to the colon where they are extensively catabolized and their microbial products absorbed into the circulation. The sum of the metabolites absorbed can reach almost 100% in some cases and in some individuals. In recent years, there have been three major areas of advancement: (a) comprehensive and systematic reviews have brought together bioavailability data, including detailed metabolic pathways in humans, and quantitative estimates of absorption and excretion; (b) the action and importance of the gut microbiota in (poly)phenol metabolism have been better defined and our understanding of the important role of the microbiota in intra- and interindividual variation has greatly expanded; and (c) strategies to improve (poly)phenol bioavailability such as encapsulation employing various nanoformulations or cyclodextrins have been developed.

3D printing has emerged as a suitable technology for creating foodstuff with functional, sensorial, and nutritional attributes. There is growing interest in creating plant-based foods as alternatives to address current demands, especially to tailor consumer preferences. Consequently, plant-derived edible inks for additive manufacturing have emerged as suitable options, including emulsion gels (or emulgels). These gels can be formulated entirely from plant-derived lipids, proteins, polysaccharides, and/or other ingredients to form complex fluids that belong to the category of soft matter. This review summarizes the most recent advances in the areas of formation, structuring, properties, and applications of plant-based emulsion gels for 3D-printed food. These semisolid materials can be extruded to the set or solidified into structures with predesigned shapes, fidelity, and sensory attributes across the senses (taste, smell, sight, and touch) along with nutrition values. Emulsion gels can be formed by either solely gelling the continuous phase or combining this process with the formation of a particle network through aggregation and close packing. The current challenges facing the development of edible inks using plant-based materials are critically discussed to stimulate further advances in the rapidly growing field of personalized 3D-printed foods.

Scavenger receptor class B member 1 (SR-B1) is a multiligand receptor with a broad range of functions spanning from the uptake of cholesteryl esters from high-density lipoproteins (HDLs) and transport of micronutrients such as fat-soluble vitamins and carotenoids across cell membranes to roles in tumor progression, pathogen recognition, and inflammatory responses. As a target of exposome factors such as environmental stressors and unhealthy lifestyle choices, as well as aging, dysregulated expression and activity of SR-B1 can negatively impact human health. Intriguingly, not only is SR-B1 a major determinant of nutrient homeostasis and, hence, metabolic health status, but these same nutrients and some phytochemicals have also demonstrated their ability to modulate SR-B1. Therefore, an integrated approach that, taking into account human health, nutrition, and food technology sciences, aims to produce foods with health-promoting effects should take advantage of the multifaceted properties of SR-B1. Improved functional foods and novel nanoparticle-based delivery systems, rich in nutrients and phytochemicals, with precise targeting to SR-B1 in specific tissues or structures could represent a strategic advance to improve human health and promote well-being.

Tea (Camellia sinensis) is one of the most popular nonalcoholic beverages in the world, second only to water. Six main types of teas are produced globally: green, white, black, oolong, yellow, and Pu-erh. Each type has a distinctive taste, quality, and cultural significance. The health-promoting effects of tea are attributed to the complex metabolite compositions present in tea leaves. These metabolite compositions vary in response to different factors. In addition to manufacturing processes in processed tea, the primary factors influencing variations of fresh tea leaf metabolites include genetics, cultivation management, and environmental conditions. Metabolomics approaches, coupled with high-throughput statistical analysis, offer promising tools for the comprehensive identification and characterization of tea leaf metabolites according to growing conditions, cultivation practices, manufacturing processes, seasonality, climate, cultivars, and geography. This review highlights the distinctive variations in fresh tea leaf metabolites, which change in response to various factors, using a metabolomics approach, which are also extended to various processed teas.

Psyllium is an excellent natural source of soluble and insoluble dietary fiber. It has been used as a nutraceutical and functional ingredient in foods. Many efforts have been made to understand and improve its physicochemical, biological, and functional properties to promote its food applications. This manuscript reviews and discusses the current knowledge of psyllium, focusing on its health benefits, utilizations as a functional additive in foods and hydrogel delivery carrier, approaches to modify its molecular and chemical structures, nonfood utilizations, and potential side effects and toxicity. Perspectives on future research and development of psyllium are also provided. This review may serve as a scientific foundation for improved food application of psyllium to enhance human health and food quality.

The emergence of several chemical substances continues to enrich and facilitate the development of food science, but their irrational use also poses a threat to food safety and human health. Nontargeted screening (NTS) has become an important tool for rapid traceability and efficient identification of chemical hazards in food matrices. NTS in food analysis is highly integrated with sample pretreatment, instrumental analysis platforms, data acquisition and analysis, and toxicology. This article is a systemic review of current sample preparation, analytical platforms, and toxicity-guided NTS techniques and provides the latest advancements in workflows and innovative applications of the NTS process based on mass spectrometric techniques. High-throughput toxicity screening platforms play an important role in NTS of unknown chemical hazards of complex food matrices. Advanced machine learning and artificial intelligence are increasingly accessible fields that may effectively process large-scale screening data and advance food NTS research.
