Zhongqi Guangdong Silicon Material Co., Ltd. specializes in customized food-grade silica dioxide solutions tailored for specific needs in downstream food applications, including solid beverages, dairy products, baked goods, seasonings, health supplements, and plant-based oils. These solutions strictly comply with international standards such as GB 25576-2020 "Food Additive Silica", FDA 21 CFR Part 182.90, USP, and FCC. The company's core strength lies in its "precision adaptation" approach:

•Full dimension customization: support particle size, purity, function (anti-cling / absorb oil / high temperature resistance / flow aid), impurity control, packaging personalized adjustment, to solve the pain point of "insufficient adaptation" of general products;

•High safety standard: customized products meet the heavy metal residue far below the international limit;
•Process compatibility: suitable for-40℃ to 250℃ different processing temperatures, no reaction with food ingredients;

•Full-process service: provide "demand research → small trial and sample → batch production → after-sales technical support" closed-loop service, free of charge to provide customized samples;

•Production capacity: Rely on 10,000-ton intelligent production line to ensure delivery stability.

Product details

2.1. Product Overview and Core dimensions of customization: accurately match downstream pain points

Conventional food-grade silica often suffers from "single functionality and fixed parameters." —— For instance, baked goods require high-temperature stability without discoloration, yet standard products tend to yellow easily. Oil absorption for deep-frying coatings needs high performance, but ordinary models lack sufficient oil absorption capacity. Similarly, fine particle sizes are crucial for milk powder filling to ensure smooth flow, yet standard products have larger particle sizes. Zhongqi Customized Food-grade Silica focuses on "end-user demands at its core," delivering tailored solutions through five customization dimensions:

2.2. R& D, production and customization assurance

(1) R&D: From demand to technical solution
The five-person special team "landed in three steps": ① Investigate the process and identify the core indicators; ② Select high-purity raw materials and adjust the process; ③ Make 3-5 sets of samples and select the best one through exclusive testing.

(2) Production side: control batch stability
GMP workshop production: ①No manual contact on automated lines, purity variation ≤0.3%; ②In addition to the standard 26-item full inspection, specialized functional tests (such as high-temperature ΔE value measurement) are added, and products can only be released upon meeting the standards; ③Supports pilot production from 1-10 tons to mass production of 50-500 tons, reducing inventory pressure.

(3) After-sales service: continuous technical support

After delivery:

① Assist in determining the optimal addition amount of 0.1%-2%;

② respond to adaptation problems (such as adjusting particle size/impurities) within 24 hours;

③ Regular follow-up and synchronous process upgrade and optimization plan.

For example, when a solid beverage enterprise produces meal replacement powder, the local concentration of vitamin is too high due to the uneven dispersion of ordinary silica. By customizing the "particle size 3-6μm + carrier function enhancement" model, the uniform dispersion of vitamin is achieved, and the product qualification rate increases from 85% to 99.5%.

3.1. Application scenarios and customized cases (covering the mainstream powdered food field)

Customized products and services in five fields: dairy products, baking, condiments, health care products and solid beverages. Typical cases are as follows:

-Case 1: dairy products (flow aid for milk powder filling)

To solve the problem of a full-fat milk powder filling error ±3% in a leading dairy enterprise, we customized an 8μm particle size + flow optimization model (D50=8±1μm, SiO₂≥99.5%, angle of retention ≤28°). The error was reduced to within ±1.5%, production line efficiency increased by 20%, and repurchase rate increased by 30%.

-Case 2: Baking (high temperature does not change color + medium oil absorption)
To address the issues of yellowing (ΔE≥2.0) and oily texture in cakes made with foreign-funded enterprise cake premix 180℃, we developed a customized formula with Fe≤0.03% + oil absorption rate of 2.5ml/kg (220℃30 minutes ΔE≤0.3, D50=10μm). This solution ensures pure white cake appearance, reduces oil seepage by 15%, extends shelf life by one month, and successfully entered the European market.

-Case 3: Seasonings (anti-clumping enhancement)
To solve the problem that the low sodium salt of an enterprise has only 12 months of anti-caking period and is easy to lump, we customized the anti-caking + moisture-proof model (the fluidity increased by 70%, the anti-caking period is 24 months, and the moisture is less than 0.5%), which remains loose for 18 months of storage, and the complaint rate decreased from 10% to 0.8%.

In addition, customized products are also used for health products (vitamin powder carrier), solid drinks (meal replacement powder with low impurities), and dehydrated egg products (protein powder dispersion) to achieve accurate matching.

Frequently Asked Questions

Q: Do customized products require additional r&d costs?
A: No extra cost —— small sample (≤300g) is free, and no customized research and development fee for batch production (≥1 ton).

Q: How can I confirm that my requirements are customizable?
A: After contacting the technical team, provide three core pieces of information: ① downstream products (such as "whole milk powder"); ② key pain points (such as "high addition amounts"); ③ critical performance metrics (such as "error tolerance ≤± 1.5%"). We will provide a feasible solution within three working days.

Q: How to guarantee the quality stability of customized products?
A: Each batch of customized products adopts "same source raw material + same production line + customized testing", the purity difference between batches is less than or equal to 0.3%, the fluctuation of key functional indicators is less than or equal to 3%, and batch comparison report is provided.

Q: Will the addition of anti-caking agent silica affect the taste of food?
A: No. The product particle size is small and the addition amount is very low (≤2%), which can be completely dispersed in the mouth without producing a sense of sand particles.

Q: Does it meet halal/Jewish food requirements?
A: Yes, the product is halal and OU KOSHER certified, and no animal source ingredients are used in the production process.

Q: How to determine the best addition ratio?
A: The technical team can provide guidance based on product characteristics and rich downstream application experience, and can also determine the optimal dosage and optimize the formula by accelerating the lumping experiment.
