As a high-performance nanomaterial extracted from natural cellulose, it is not only renewable, non-toxic and environmentally friendly, but also lightweight, high-strength, transparent and flexible, and has brought technological innovation to many industries. 1. Core performance advantages of nanocellulose Excellent mechanical properties The specific strength and specific modulus of nanocellulose are comparable to steel. Its strength comes from the dense hydrogen bonding between cellulose molecules and the nanoscale fiber structure. This high-strength property makes it an ideal reinforcement material that can significantly improve the structural stability of composite materials. Excellent dispersion and film-forming properties. After surface modification such as TEMPO oxidation, nanocellulose shows excellent dispersion and stability in the aqueous phase and can self-assemble to form a highly transparent film.

Nanocellulose is a nanostructured material obtained from natural cellulose after physical, chemical or enzymatic treatment. It has excellent properties such as high strength, light weight, reproducibility and biocompatibility. It is known as the 'new generation of green nanomaterials'. It mainly includes three types: cellulose nanocrystals (CNC), cellulose nanofibers (CNF) and bacterial cellulose (BC). The following is a systematic introduction from the perspective of main performance: 1. Excellent mechanical properties Nanocellulose has extremely high specific strength and specific modulus. Its tensile strength can reach 7~8 GPa, which is higher than steel; its elastic modulus is about 100~140 GPa. This gives it great potential in high-performance composites, flexible electronics and structural reinforcements. Even at extremely low filling amounts, the mechanical properties of the matrix can be significantly improved. 2. Stable thermal properties The thermal decomposition temperature of nanocellulose is generally 2

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
