CNC natural nanocellulose: empowering the food industry and creating a dual upgrade plan for healthy taste. Recently, cellulose nanocrystals (CNC), as a new natural food additive, have achieved important breakthroughs in the field of dairy processing. Its excellent performance in thickening, stabilization, emulsification and fat replacement has provided a new path for the green and healthy transformation of the food industry, and has become the core technical support for promoting high-quality development of the industry. As an enterprise deeply involved in the field of nanocellulose, Nanjing Tianlu Nanotechnology Co., Ltd. (a subsidiary of Huikang Biotechnology) is relying on its own technological advantages to promote the industrial application of CNC-related products and help the innovation and upgrading of the food industry. CNC is a nano-scale crystal separated and purified from natural plant fibers such as wood and cotton. It has the advantages of high specific surface area, good biocompatibility, degradability, etc., and is of natural origin, non-toxic and harmless. It can play an efficient role at low concentrations without changing the flavor of the food itself, making it a perfect fit.

With the rapid development of industrial production and marine transportation, oil spill control and industrial oily wastewater treatment have become key problems in the field of environmental protection. Traditional oil-water separation materials have shortcomings such as low adsorption efficiency, non-degradability, and prone to secondary pollution, and cannot meet the current dual needs of green environmental protection and resource recycling. Superhydrophobic/superoleophilic nanocellulose sponges and superhydrophobic/superoleophilic nanocellulose aerogels, as core products for environmentally friendly applications of nanocellulose, have become the preferred solution to oil and water pollution with their advantages of natural environmental protection, efficient separation, and recyclability. They are widely used in many fields such as marine oil spills, industrial wastewater, and high-end protection. As a professional enterprise deeply involved in the field of nanocellulose, Nanjing Tianlu Nanotechnology Co., Ltd. is located in Jiangning District, Nanjing, the ancient capital of the Six Dynasties. It focuses on the research and development, production and sales of nanocellulose series products, relying on a 25,000 square meter modern production base, advanced production lines and professional R&D teams.

Legal documents such as ID cards, passports, and driver's licenses are the core carriers of personal identification, and their anti-counterfeiting properties are directly related to personal information security, social integrity systems, and national public security. Current traditional document anti-counterfeiting technologies (watermarks, fluorescent inks, magnetic stripes, etc.) are affected by the upgrade of counterfeiting technology, and have pain points such as easy copying, high identification thresholds, and easy failure after long-term use. Nanocellulose structural color materials have become a new core technology in the field of document anti-counterfeiting by virtue of their core advantages of being natural and environmentally friendly, difficult to copy, and easy to identify, effectively improving the level of document anti-counterfeiting and building a solid line of defense for information security. 1. Nanocellulose: a new green core material for document anti-counterfeiting. Nanocellulose is a green nanomaterial extracted from natural plants. Its core competitiveness in the field of document anti-counterfeiting stems from its unique structural color properties - different from the color development of traditional chemical pigments, the color of nanocellulose comes from the physical control of light by the microscopic orderly structure. This 'structure determines color'
