INTRODUCTION
Probiotics, defined as stay microorganisms that confer health benefits whilst fed on in adequate amounts, have received much interest within the food industry. The idea of using useful microorganisms for promoting health and wellbeing may be traced back to centuries of using fermented ingredients and conventional remedies. However, recent medical studies have shed light on the mechanisms of motion and ability applications of probiotics [1], [2], [3]. Functional ingredients, also called nutraceuticals, are food products that provide extra health benefits beyond basic vitamins. They are designed to optimize physiological functions and reduce the danger of certain diseases. Probiotics constitute one of the key components in the development of useful ingredients because of their ability to modulate the intestine microbiota, improve digestion, enhance immune features, and exert anti-inflammatory outcomes [4]. The intestine microbiota, a complicated community of microorganisms residing within the gastrointestinal tract, performs an essential role in human health. Disruptions inside the gut microbiota have been associated with diverse fitness situations, which include gastrointestinal disorders, metabolic problems, and immune dysregulation. Probiotics taken orally can engage with the gut microbiota and affect its composition and interest, consequently resulting in useful effects on host health [4]. The

Role of Microencapsulation in Improving Probiotic Viability, Stability, and Delivery
Microencapsulation is a valuable technique for enhancing probiotics' viability, stability, and delivery in functional foods. It involves the encapsulation of probiotic cells within protective polymeric materials, forming microspheres or particles that act as a physical barrier against environmental stresses. This protective barrier is crucial in improving probiotic viability, stability, and delivery. One of the key benefits of microencapsulation is its ability to protect probiotics against harsh conditions during processing. The encapsulating polymers create a barrier that reduces the exposure of probiotic cells to heat, shear forces, and pH changes. This protection minimizes cell damage and improves the viability of probiotics during processing, ensuring a higher number of viable cells in the final product [12], [13]. Microencapsulation also enhances the shelf stability of probiotics in functional foods. The encapsulating polymers create a microenvironment that helps maintain probiotics viability by reducing moisture uptake, preventing oxygen exposure, and minimizing interactions with other food components. This increased stability allows for a longer storage period without significant losses in probiotics viability, ensuring the product's efficacy over time. Another important aspect of microencapsulation is its impact on probiotics survival in the gastrointestinal tract. As mentioned earlier, the encapsulating polymers provide a physical barrier that protects probiotic cells from the acidic conditions of the stomach and the presence of bile salts in the small intestine. This barrier reduces cell damage and increases the survival rates of probiotics, enabling a larger number of encapsulated cells to reach the colon, where their beneficial effects are exerted [14], [15]. Microencapsulation also enables the controlled release and targeted delivery of probiotics. The encapsulating polymers can be designed to release probiotics in a controlled manner, allowing for sustained release over time. This controlled release ensures prolonged exposure of probiotics to the gut environment, increasing their chances of colonization and persistence. Additionally, microencapsulation facilitates targeted delivery to specific sites in the gastrointestinal tract, optimizing the therapeutic effects of probiotics [16], [17]. Furthermore, microencapsulation offers compatibility with various food matrices, allowing the incorporation of probiotics into a wide range of functional food products. The encapsulating polymers can be tailored to withstand the specific conditions of the food matrix, maintaining probiotics viability and functionality. This versatility enables the development of probiotic-enriched foods with diverse textures, flavors, and processing requirements [18], [19]. Figure 1 depicts the material used in the microencapsulation mechanism. Microencapsulation strategies involve the encapsulation of probiotic cells within defensive polymeric substances, forming microspheres or debris. These encapsulating systems act as a barrier, providing safety to the probiotics and enabling managed launch and focused delivery. Several microencapsulation methods have been developed and utilized for probiotics delivery [23], [24]. One normally used approach is spray drying, which includes atomizing a probiotic-containing suspension right into a drying chamber. The droplets come in contact with a hot air circulation, resulting in fast evaporation of the solvent and the formation of dried particles. These debris encompass probiotic cells embedded within the polymer matrix [25].

Overview of Microencapsulation Methods
Another technique is the extrusion technique, in which a mixture of probiotic cells and a polymer solution is extruded through a small orifice, forming continuous strands. These strands are then cut into smaller debris to obtain microspheres or beads containing the probiotics. The coating technique includes coating probiotic cells with a polymer layer. Some techniques include fluidized bed coating, pan coating, or electrostatic coating. Multiple layers of polymers are deposited onto the probiotic cells, growing a shielding barrier. The emulsion approach includes the formation of an emulsion gadget comprising a probiotic-containing water segment, a polymer answer, and an emulsifier. The emulsion is then subjected to solvent evaporation or crosslinking to solidify the polymer matrix and encapsulate the probiotics [26], [27]. Coacervation is a phase separation approach wherein a polymer answer is delivered into contact with a non-solvent, forming a polymer-rich coacervate phase.
The probiotic cells are then suspended or dispersed inside this coacervate segment and hardened to shape microcapsules.
Each microencapsulation method offers specific benefits and disadvantages. Some benefits of microencapsulation include the protection of probiotic cells from harsh environmental situations, controlled release of probiotics through the years, targeted delivery to unique regions of the gastrointestinal tract, and enhanced stability all through storage and processing [28], [29]. However, there are also barriers and challenges related to microencapsulation techniques. Some techniques can be expensive and require specialised device, making them less economically feasible for large-scale manufacturing. Certain methods, such as coacervation and emulsion strategies, may be complicated and require precise control over manner parameters. The encapsulation process may additionally exert stress on probiotic cells, potentially resulting in a loss of viability. Scaling up microencapsulation techniques from the laboratory to business scale can also pose demanding situations in terms of process scalability, reproducibility, and cost-effectiveness. Despite these challenges, microencapsulation strategies remain precious for protecting and delivering probiotics. Ongoing research keeps optimizing and developing those techniques for various packages [30].

Different strategies, including spray drying or extrusion, can subject probiotic cells to high temperatures or shear forces that may potentially harm them. It is crucial to optimize the procedure parameters and situations to minimize stress and ensure minimum impact on probiotic viability [37]. The selected polymer must match well with probiotics and not cause toxicity or harm. Therefore, it is important to choose a biocompatible polymer with good enough protection and that does not compromise probiotic viability [38]. Encapsulation performance, which refers to the proportion of probiotic cells efficaciously encapsulated inside the microspheres or particles, can also affect probiotic viability. Low encapsulation efficiency means that many probiotic cells remain unprotected and are prone to environmental stresses. Hence, optimizing the encapsulation technique to gain high efficiency is crucial for optimum probiotic encapsulation and protection. The preliminary concentration of probiotic cells used during microencapsulation can also affect viability. High cellular concentrations can result in improved cell-to-mobile interactions, resulting in clumping or aggregation that can reduce viability. Therefore, it is important to optimize mobility to decrease aggregation and ensure uniform distribution in the microcapsules [39], [40]. The use of shielding products, such as cryoprotectants or osmoprotectants, in microencapsulation can also impact probiotic viability. These products help mitigate the stress on probiotic cells at some point of processing and storage [41]. If the microencapsulation technique involves drying, the drying conditions can also affect probiotic viability. Controlling temperature, airflow, and drying time is important to decrease warmness and oxidative stress all through drying, as a result assisting to keep probiotic viability and capability. Proper storage conditions, such as temperature, humidity, and exposure to mild, significantly impact probiotic viability at some stage in storage. Implementing appropriate storage conditions, together with refrigeration or freeze-drying, is important to ensure long-time viability and stability of the microencapsulated probiotics [42], [43]. Lastly, the aim of microencapsulation is also to decorate probiotic viability at some point of gastrointestinal transit. Factors such as resistance to acidic situations in the stomach, and protection in opposition to enzymatic degradation. Therefore, the microencapsulation method should ensure most probiotic viability and colonization inside the gastrointestinal tract. By thinking about and optimizing those factors for the duration of microencapsulation, the viability of probiotics may be better, ensuring their efficacy and functionality in functional foods. Thorough research and optimization studies are vital to discover top-quality situations for precise probiotic lines and encapsulation strategies [44].
