Evonik Degussa Voedselgraad Silica Anti-Klontmiddel: Prestasie en Uitdagings

Evonik Degussa's food-grade silica anti-caking agents, centered on the Sipernat® and AEROSIL® product lines, hold a significant position in the global food additive market due to advanced manufacturing processes and strict quality control. The following is a detailed analysis from the aspects of product characteristics, market position, advantages, and limitations:

I. Core Product Information and Technical Parameters

1. Produktyn en Proseskenmerke

• Sipernat® Series (Precipitated Silica)

Represented by Sipernat® 22S and 50S, they are produced through a precipitation process, featuring high oil absorption (e.g., Sipernat® 22S has a DBP oil absorption value of 265%) and uniform particle size distribution (average particle size 7-11.5 μm). Their porous structure can adsorb oils and moisture in food, forming a physical barrier to prevent caking, making them suitable for high-fat content foods (such as milk powder, baking fats) and powdered seasonings.

◦ Iparametere zeNtlawulo:

▪ SiO₂ content: ≥98% (Sipernat® 22S)

▪ Specific surface area: 190 m²/g (Sipernat® 22S)

▪ Loss on drying: ≤6% (at 105°C for 2 hours)

• AEROSIL® Series (Fumed Silica)

Tsarin hanyar su na uku na iya inganta yawan motsi na foda, wanda ya dace da kayayyakin madara na sama, kari na gina jiki da sauran yanayi tare da tsauraran bukatu akan rarrabawa.

◦ Tekniese Parameters:

▪ SiO₂ content: >99.8%

▪ Bulk density: approximately 50 g/L

▪ Compliance certifications: in line with EC No. 852/2004, FDA 21 CFR 172.480 and FAMI-QS standards

2. Ukuhlaziywa Kwezisebenzi Eziyinhloko

• Anti-caking Mechanism: Through physical adsorption (oil absorption value 265-300 g/100g) and spatial barrier effect, it prevents particles from aggregating due to humidity or static electricity.

• Fluidity Optimization: I-nanostructure ye-AEROSIL® 200F inganciphisa kakhulu i-friction coefficient ye-powder, igcine imikhiqizo efana ne-milk powder ikhululekile endaweni ye-40°C/75% RH.

• Carrier Function: Sipernat® 50S can adsorb liquid flavors or vitamins, converting them into free-flowing solid powders, thereby extending the shelf life of sensitive ingredients.

II. Global Market Position and Competitive Landscape

1. Makhte Share na Indastri Ranking

• Global Competitiveness: Evonik is one of the major suppliers of fumed silica (accounting for about 35% of the high-end food-grade anti-caking agent market) and precipitated silica globally, jointly dominating the market with Cabot and Wacker.

• Regional Layout: In the Asia-Pacific region, Evonik's food-grade silica has a market share of about 18%, especially in the high-end dairy products and health products fields.

2. Iindawo Zokuncintisana

• Izithiyo Zobuchwepheshe: Uchungechunge lwe-AEROSIL® olwenziwe ngogesi luphakeme kunezimbangi ezifana ne-PQ ne-Grace uma kuziwa ekusabalaleni kwe-nanoscale nasekuzinzeni kokushisa (ukumelana nezinga lokushisa elingaphezu kuka-200°C).

• Compliance Coverage: Iimpahla zidlule izitifiketi eziningi zamazwe omhlaba ezifana ne-FDA, i-EFSA, kanye ne-Kosher, zisekela izinkampani zokucubungula ukudla ezihloselwe ukuthumela ngaphandle ukuze zihlangabezane nezidingo zomthetho zomhlaba wonke.

III. Iphuzu Ehlukile Nezici Zobuchwepheshe

1. Leading Performance

• Anti-caking Efficiency: The oil absorption value of AEROSIL® 200F (280-300 g/100g) is higher than that of Grace SYLOID 63 FP (200 g/100g), performing better in high-humidity environments.

• Processing Compatibility: I-high bulk density yeSipernat® series (isb. Sipernat® 22S ingama 6.2 lb/ft³) yehlisa i-electrostatic adsorption, ikhulisa ukuhlanganiswa nezinye izithako.

2. Sustainability and Process Innovation

• Green Production: Evonik promotes the resource utilization of wastewater from the precipitation process, reducing water consumption per ton of products by 40%, which is in line with China's "Dual Carbon" policy orientation.

• Customized Services: Hydrophobic modified grades (such as AEROSIL® R972) and high specific surface area models (such as AEROSIL® 300) are provided to meet special application needs.

IV. Izinqumo kanye Nezinkinga Zokusebenza

1. Cost and Economy

• High Cost of Fumed Method: The price of the AEROSIL® series is 30-50% higher than that of precipitated products, limiting its application in low-end foods (such as ordinary table salt).

• Sensitivity to Addition Amount: Excessive use may lead to excessive dispersion of powders, affecting food taste (such as graininess when milk powder is brewed).

2. IziMiso neUkuhambisana

• Regional Restrictions: In the European Union, the maximum usage of silica (E 551) in table salt is 5 g/kg, and some models of Evonik require additional permits due to particle size issues.

• Izingo Zokuhlangana: Ukuxhumana isikhathi eside nezinto ezinamandla eziphikisanayo noma eziphakeme kunganciphisa ukusebenza kokumunca, ngakho-ke kufanele kwenziwe izivivinyo zokuhlangana kuqala.

3. Dust Control

• Production Challenges: The low density (50 g/L) of the AEROSIL® series is prone to dust generation, requiring professional dust removal equipment in clean workshops.
