It has an ultra-large specific surface area and a rich microporous structure, enabling it to accurately absorb excess oil in food. After absorption, it remains stable in properties – it is insoluble in oil and does not produce off-flavors.
In the processing and application of powdered flavors, non-discoloring food-grade silicon dioxide plays an important role: It not only maintains the pure color of flavors to ensure the final food has consistent flavor and appearance but also strictly adheres to food safety standards.
Universal food-grade silicon dioxide has become the preferred choice for many food enterprises, thanks to its characteristics of "wide applicability across scenarios and high safety".
Problems like lumpy milk powder that’s hard to dissolve, caked seasonings that affect dosage, and clumpy protein powder that ruins the taste…
In the future, with the upgrading of technology and the improvement of regulations, food-grade silica dioxide will adapt to different food scenarios more accurately, transforming from "basic improvement" to "functional enhancement" and continuing to protect food quality and consumer health.
This extends the oil's service life and reduces the frequency of waste oil replacement, aligning with the catering industry's needs for cost reduction, efficiency improvement, and green transformation.
It is difficult to be completely replaced in the short term. It has multiple functions such as anti-caking, stabilization, and adsorption, with low cost and high safety. Although there are other anti-caking agents (such as tricalcium phosphate)
How do manufacturers ensure E551 is gluten-free? Dedicated equipment and third-party testing. Brands like Evonik provide gluten-free certificates for food-grade batches.
Food-Grade Silicon Dioxide (SiO₂) is purified, amorphous silica that meets food additive safety standards. Produced primarily via fumed or precipitated processes, it appears as a white powder with odorless, tasteless, and chemically inert properties.
Against the backdrop of the global food industry’s drive toward refined upgrading, food-grade silicon dioxide (EU code: E551; China CNS No.: 02.004) has emerged as an indispensable core functional additive in sectors like milk powder, condiments, and beverages.
