Nanocellulose is a nanoscale material based on natural cellulose and processed by physical, chemical or enzymatic means. Due to its unique crystal structure, high specific surface area and intermolecular hydrogen bonding network, nanocellulose has excellent mechanical properties, thermal stability, chemical modification and biocompatibility. It is considered to be one of the key materials to achieve the goal of 'petroleum replacement' and 'material sustainability'. Nanjing Tianlu Nanotechnology Co., Ltd. has long been focused on the R&D and production of nanocellulose, especially in TEMPO oxidative modification, carboxylation compounding and dispersion system optimization, and has accumulated rich technical experience to provide high-performance solutions for the fields of medicine, packaging, functional coatings and polymer composite materials. 1. Excellent mechanical properties endowed by high crystalline structure. The mechanical strength of nanocellulose mainly comes from its high crystallinity cellulose Iβ crystal structure.

1. Introduction Driven by the 'dual carbon strategy' and green manufacturing, new sustainable materials are becoming the focus of global industrial change. Nanocellulose (Nanocellulose) is considered an important candidate to replace petroleum-based polymer materials due to its high strength, light weight, renewable, degradable and easy functionalization. Especially in the medical and health field, nanocellulose is reshaping application scenarios such as medical dressings, tissue engineering scaffolds, and drug sustained release due to its excellent biocompatibility and designability. 2. Structure and preparation technology of nanocellulose Cellulose is the most abundant natural polymer on earth. It can be deconstructed to the nanometer scale through mechanical, chemical or biological methods to form nanocellulose with high specific surface area and high crystallinity.

1. Introduction With the continuous improvement of people's health awareness, low-calorie and high-fiber foods have gradually become the mainstream of the market. From sugar-controlled drinks to plant-based meal replacements, consumers' pursuit of 'light nutrition' and 'low burden' has driven innovation in food formulation technology. Among many natural dietary fibers, bacterial cellulose (BC) is considered an important representative of the new generation of low-calorie functional dietary fibers due to its unique molecular structure and functional properties. Not only does it have extremely high purity and excellent physical properties, it can also improve the texture and taste of food without adding calories. 2. Structural characteristics and biological advantages of bacterial cellulose Bacterial cellulose is a natural polysaccharide synthesized by fermentation of Acetobacter xylinus. Compared with cellulose from plant sources, it has the following significant advantages: high purity and impurity-free structure: fine

Innovative applications of bacterial cellulose in beverage and dairy product stabilizers In the modern food industry where health and quality are both important, the stability of beverages and dairy products has become one of the key technical indicators. Consumers expect drinks to have a delicate taste and uniform structure without stratification or sedimentation; dairy products require smooth texture and long-lasting flavor. However, traditional stabilizers such as gelatin, sodium carboxymethylcellulose (CMC) or guar gum often have problems such as heat sensitivity, high addition amounts, or impact on taste. In recent years, bacterial cellulose (BC), a natural polysaccharide derived from microbial metabolism, is becoming a new stabilizer in the beverage and dairy industries. 1. What is bacterial cellulose? Bacterial cellulose is high-purity cellulose secreted by microorganisms such as Acetobacter xylinus during the fermentation process. Unlike plant cellulose,

1. Introduction to Nanocellulose Nanocellulose is a nano-scale material obtained by mechanical, chemical or enzymatic treatment of natural cellulose, with a diameter of only 5–100 nm. Because it comes from plant fiber or bacterial fermentation, it is not only green and environmentally friendly, but also has high strength, light weight, degradability, excellent transparency and other characteristics. Among them, high transparency is one of the most valuable features of nanocellulose in electronic and functional film applications. 2. Advantages of high transparency of nanocellulose. Excellent optical performance: The diameter of nanocellulose fibers is much smaller than the visible light wavelength (400–700 nm), so it can effectively reduce light scattering and show high transparency. High light transmittance: The light transmittance of nanocellulose transparent films can reach 85–95%, comparable to glass and polymer transparent films. Low haze: The material structure is uniform and the haze is low, suitable for flexible displays with extremely high requirements for visual clarity

1. Introduction to Nanocellulose Nanocellulose is a functional material that processes natural cellulose into nanoscale structures through mechanical, chemical or enzymatic methods. It comes from plant fibers, bacterial fermentation or algae resources, and is usually 5–100 nm in diameter and can reach several microns in length. Compared with traditional materials, nanocellulose is not only environmentally friendly and degradable, but also exhibits amazing mechanical properties. 2. The specific strength and modulus stronger than steel. In materials science, specific strength refers to the ratio of the strength and density of a material, and the specific modulus refers to the ratio of the elastic modulus to density. The specific strength and modulus of nanocellulose are far greater than those of steel because of: nanostructure effect: the cellulose crystal region at the nanoscale is highly ordered, and the intermolecular hydrogen bonding is enhanced. High crystallinity: The crystallinity of cellulose nanocrystals (CNC) is as high as 60–90%, significantly improving mechanical properties. Lightweight properties: low density (approximately 1.5
