Nanobiotechnology Unveils the Power of Probiotics: A Comprehensive Review on the Synergistic Role of Probiotics and Advanced Nanotechnology in Enhancing Geriatric Health

The geriatric population, comprising ages 65 and above, encounters distinct health obstacles because of physiological changes and heightened vulnerability to diseases. New technologies are being investigated to tackle the intricate health requirements of this population. Recent advancements in probiotics and nanotechnology offer promising strategies to enhance geriatric health by improving nutrient absorption, modulating gut microbiota, and delivering targeted therapeutic agents. Probiotics play a crucial role in maintaining gut homeostasis, reducing inflammation, and supporting metabolic functions. However, challenges such as limited viability and efficacy in harsh gastrointestinal conditions hinder their therapeutic potential. Advanced nanotechnology can overcome these constraints by enhancing the efficacy of probiotics through nano-encapsulation, controlled delivery, and improvement of bioavailability. This review explores the synergistic potential of probiotics and advanced nanotechnology in addressing age-related health concerns. It highlights key developments in probiotic formulations, nano-based delivery systems, and their combined impact on gut health, immunity, and neuroprotection. The convergence of probiotics and nanotechnology represents a novel and transformative approach to promoting healthy aging, paving the way for innovative therapeutic interventions.

Exploring the extraction, functional properties, and industrial applications of papain from Carica papaya

Papain a protease enzyme naturally present in the Carica papaya has gained significant interest across several industries due to its unique properties and versatility. The unique structure of papain imparts the functionality that assists in elucidating how papain enzyme works and making it beneficial for a variety of purposes. This review highlights recent advancements in papain extraction techniques to enhance production efficiency to meet market demand. The extraction of papain from the Carica papaya plant offers various advantages such as cost-effectiveness, biodegradability, safety, and the ability to withstand a wide range of pH and temperature conditions. Key findings reveal that non-conventional papain extraction techniques offer significant advantages in terms of efficiency, product quality, and environmental sustainability. Furthermore, papain treatment enhances the value of final products due to its anti-bacterial, anti-oxidant, and anti-obesity properties. The ability of papain to hydrolyze a wide range of proteins across various conditions makes it a suitable protease enzyme. While the study emphasizes the advantages of papain, the study also acknowledges limitations such as the continuous research and development to optimize extraction processes which will help unlock papain's potential and meet the growing demand. © 2024 Society of Chemical Industry.

The Application of High-Intensity Ultrasound on Wet-Dry Combined Aged Pork Loin Induces Physicochemical and Oxidative Alterations

This research investigated the synergic outcome of high intensity ultrasound (HIU) treatment and wet-dry combined aging (WDCA) on physiochemical characteristics and lipid oxidation during refrigerated storage to ameliorate pork meat's quality and shelf life. The CIE b* values, cooking loss (CL %), and pH of the HIU treated samples were higher than those of the control over the aging period. They were significantly (p<0.05) modified by the aging period and ultrasound (US) treatment. However, the released water (RW %) and moisture were not significantly influenced by US treatment (p>0.05). The Warner-Bratzler shear force of HIU-treated samples was lower over control values except in 7-14 d, and it showed a significant difference between control and US treatment according to the significance of HIU (p<0.05). The thiobarbituric acid reactive substance of HIU-treated samples was significantly higher (p<0.05) than control values over the aging period. These results suggested that HIU treatment and WDCA showed a synergistic effect of maximizing the tenderness, but lipid oxidation was higher than before ultrasonic treatment. In agreement with this, the most favorable approach would involve implementing wet aging for a period of two weeks followed by dry aging for a period not exceeding one week after the application of HIU.

Exploring the Therapeutic Potential of Bromelain: Applications, Benefits, and Mechanisms

Bromelain is a mixture of proteolytic enzymes primarily extracted from the fruit and stem of the pineapple plant (Ananas comosus). It has a long history of traditional medicinal use in various cultures, particularly in Central and South America, where pineapple is native. This systematic review will delve into the history, structure, chemical properties, and medical indications of bromelain. Bromelain was first isolated and described in the late 19th century by researchers in Europe, who identified its proteolytic properties. Since then, bromelain has gained recognition in both traditional and modern medicine for its potential therapeutic effects.

Study on the current research trends and future agenda in animal products: an Asian perspective

This study aimed to analyze the leading research materials and research trends related to livestock food in Asia in recent years and propose future research agendas to ultimately contribute to the development of related livestock species. On analyzing more than 200 relevant articles, a high frequency of studies on livestock species and products with large breeding scales and vast markets was observed. Asia possesses the largest pig population and most extensive pork market, followed by that of beef, chicken, and milk; moreover, blood and egg markets have also been studied. Regarding research keywords, "meat quality" and "probiotics" were the most common, followed by "antioxidants", which have been extensively studied in the past, and "cultured meat", which has recently gained traction. The future research agenda for meat products is expected to be dominated by alternative livestock products, such as cultured and plant-derived meats; improved meat product functionality and safety; the environmental impacts of livestock farming; and animal welfare research. The future research agenda for dairy products is anticipated to include animal welfare, dairy production, probiotic-based development of high-quality functional dairy products, the development of alternative dairy products, and the advancement of lactose-free or personalized dairy products. However, determining the extent to which the various research articles' findings have been applied in real-world industry proved challenging, and research related to animal food laws and policies and consumer surveys was lacking. In addition, studies on alternatives for sustainable livestock development could not be identified. Therefore, future research may augment industrial application, and multidisciplinary research related to animal food laws and policies as well as eco-friendly livestock production should be strengthened.
