1.1 Basic definitions
Zhongqi Premium Pet Food Silica is a functional additive made from food-grade materials through precision precipitation and low-temperature drying processes, presenting as a white, ultra-fine, fluffy powder. Its core features include a low-dust porous structure and excellent biocompatibility, combining high-efficiency anti-caking properties with nutrient carrier functions. It does not react with protein, probiotics, trace elements, or other components in pet food, making it a key quality-enhancing ingredient for premium dog food, cat food, and pet snacks.

1.2 Core values
As a critical stabilizing additive for premium pet feed, Zhongqi's silicon dioxide effectively addresses industry pain points of traditional anti-caking agents, including poor palatability, low nutrient adsorption rates, and long-term consumption safety risks. Through precise pore structure and particle size regulation, it stably delivers probiotics, Omega-3, and other active nutrients while minimizing nutrient loss. The product complies with GB 25576-2020 and EU EC feed additive standards, providing high-end pet food manufacturers with safe and efficient quality enhancement solutions.

Key Technical Parameters

Application Fields

1. Freeze-dried staple food and functional snacks: improve the rehydration efficiency of freeze-dried tablets, help intestinal absorption, reduce nutrient residue in feces; spray on the surface of frozen chicken breast snacks to adsorb oil and prevent sticking, prolong shelf life and improve palatability.
2. Probiotics and Enzyme Pre-mixes: The three-dimensional porous structure (specific surface area 150-400 m²/g) can encapsulate over 90% of microbial agents. For example, when formed as a stable solid solution in Bacillus subtilis pre-mixes, it maintains high heat resistance (80-90°℃) and enzyme activity. In protease pre-mixes, the inert environment (pH6.0-8.0) neutralizes acidity, prevents enzymatic inactivation, and simultaneously adsorbs moisture to avoid clumping.
3. Mineral and Vitamin Carriers: These carriers can transport 30%-50% of their own weight in trace components, forming a sustained-release system through surface silanol groups (-SiOH). For instance, the puppy growth formula contains calcium and magnesium ions to prevent phytic acid binding and enhance utilization efficiency. Similarly, senior dog food adsorbs vitamin E and selenium to inhibit oxidation.
4. Oral care and functional diet: Rough particle surface physical cleaning, adsorption of oral odor. For example, after adding a brand of complete cat food, the calculus index decreased by 25% in 30 days; in the low-phosphorus formula food for cats with kidney disease, free phosphorus ions were adsorbed to reduce blood phosphorus and regulate intestinal pH value to relieve vomiting.

Key advantages

4.1 Optimization of physical properties: ensure stable feed quality
4.1.1. Anti-caking and Flow Improvement: At 25℃ and 60% humidity levels, the product maintains a moisture absorption rate ≤5% to prevent caking by adsorbing free moisture. Its three-dimensional porous structure (specific surface area 150-400 m²/g) can carry 30%-50% of active ingredients while ensuring powder flow. The probiotic premix demonstrates over 90% microbial encapsulation rate, with a 30-day survival rate 20% higher than montmorillonite-based formulations.
4.1.2. Dust control and processing efficiency: The surface of coarse particles can reduce dust by 40% compared with organic carriers, improve the environment and reduce equipment wear; the particle size of 10-100μm in freeze-dried pet food can optimize the compaction rate to 55%-60%, improve the rehydration efficiency and promote intestinal peristalsis.

4.2 Functional component protection: prolong shelf life of active substances
4.2.1. Carrier and sustained-release effect: The porous structure adsorbs vitamins and enzyme preparations to form a stable state, such as precipitated silica loaded with vitamin B12 to reduce the risk of stratification; when used as flavor carrier, the dosage according to FDA regulations is less than 2%, which can achieve accurate release.
4.2.2. Chemical stability barrier: pH6.0-8.0 inert environment can neutralize acid corrosion and avoid alkali reaction; melting point 1700℃, high temperature resistance of 80-90℃ granulation, better than the traditional organic carrier with variability above 60℃.

4.3 Health function enhancement: improve the physiological performance of pets
4.3.1 Gut health regulation: High adsorption of pathogenic bacteria and toxins to reduce the risk of diarrhea; help the Bacillus subtilis formula maintain the balance of flora, promote villus growth to improve absorption rate; porous structure adsorbs excess water, regulate intestinal pH to adapt sensitive gastrointestinal tract.
4.3.2 Bone and coat health support: Silicon is involved in collagen synthesis, strengthening bones, joints and coat, and synergizing with calcium and magnesium to promote bone development of dogs and cats and improve nail strength; the high-end formula can adsorb heavy metals and reduce potential hazards.

5. Standards and regulations (Standards & Regulations)
•Comply with national and industry standards: GB25576-2020 standard, "Silica for Feed" standard.
•Obtain relevant qualification certification: feed additive production license, FAMIQS.
•Follow the safety specification requirements: acute toxicity test (LD50> 5000mg/kg) is determined to be non-toxic, and the microbial limit is less than or equal to 1000CFU/g, which meets the long-term food safety standards for pets, and is suitable for puppies, kittens and elderly pets.

Product Advantages

•High safety level: food grade raw materials and processes, heavy metal content is far below the industry standard, suitable for high-end pet food "safety first" needs, long-term consumption no health risks.
•Strong functional synergy: it has the three functions of anti-caking, carrier and preservation, which reduces the type of auxiliary materials in feed, simplifies the formula design and reduces the production cost of enterprises.
•Precise scene adaptation: according to dog food, cat food, snacks and different application fields, the models are subdivided to match the raw material characteristics and storage requirements of different pet food, so as to improve product pertinence.
•Good stability and reliability: the deviation of anti-caking rate and carrier activity retention rate in each batch is less than 5%, which is suitable for large-scale pet food production and ensures product quality consistency.
