Evonik Degussa Ukudla-Ikhwalithi Silica Anti-Caking Agent: Ukusebenza Nezinselelo
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. Imigqa Yezinto Nezici Zokusebenza
• 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.
◦ Izimfanelo Zobuchwepheshe:
▪ SiO₂ content: ≥98% (Sipernat® 22S)
▪ Specific surface area: 190 m²/g (Sipernat® 22S)
▪ Ukulahleka kokomisa: ≤6% (ku-105°C isikhathi esingama-2)
• AEROSIL® Series (Fumed Silica)
Represented by AEROSIL® 200F, they are prepared using a flame hydrolysis process, with nanoscale particles (average particle size 12 nm) and ultra-high specific surface area (175-225 m²/g). Their three-dimensional network structure can effectively improve the fluidity of powders, suitable for high-end dairy products, nutritional supplements and other scenarios with strict requirements on dispersibility.
◦ Izimfanelo Zobuchwepheshe:
▪ SiO₂ content: >99.8%
▪ Bulk density: approximately 50 g/L
▪ Izitifiketi zokuhambisana: kuhambisana ne-EC No. 852/2004, FDA 21 CFR 172.480 kanye nezindinganiso ze-FAMI-QS
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: The nanostructure of AEROSIL® 200F can significantly reduce the friction coefficient of powders, keeping products like milk powder loose in an environment of 40°C/75% RH.
• Carrier Function: Sipernat® 50S ingakwazi uku-adsorb ama-flavor noma ama-vitamins, iyaguqula ibe ama-powder aqhubekayo, ngaleyo ndlela ikhulisa impilo yeshelufu yezingxenye ezibucayi.
II. Global Market Position and Competitive Landscape
1. Umthamo Wemakethe kanye Nezinga Lezobuchwepheshe
• 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. Izindawo Zokuncintisana Zokuhlakanipha
• Izithiyo Zobuchwepheshe: Uchungechunge lwe-fumed AEROSIL® luphumelela kubancintisana nabo njenge-PQ ne-Grace uma kuziwa ekusabalaleni kwe-nanoscale nasekuzinzilekeni kokushisa (ukumelana nezinga lokushisa elingaphezu kuka-200°C).
• Compliance Coverage: Iziphumo zedivayisi zidlulelwe kwiikhowudi ezininzi zamazwe ngamazwe ezifana ne-FDA, i-EFSA, kunye ne-Kosher, zixhasa amashishini okucoca ukutya aphumelelayo ukuhlangabezana neemfuno zomthetho zomhlaba.
III. Izinzuzo Ezingafani Nezici Zobuchwepheshe
1. Ukuhola Ukusebenza
• 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.
• Ukucubungula Ukuhambisana: Ubukhulu obuphezulu be-Sipernat® uchungechunge (isb. Sipernat® 22S ngu-6.2 lb/ft³) buhlinzeka ukunciphisa ukuheha kwe-electrostatic, kulula ukuhlanganisa nezinye izithako.
2. Ukuqhubeka nokwakhiwa kwezindlela ezintsha
• 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.
• Izinsizakalo Ezenziwe Ngokwezifiso: Amagradi aguquliwe anokungena kwamanzi (njengoba AEROSIL® R972) namamodeli anendawo ethile ephezulu (njengoba AEROSIL® 300) anikezwa ukuze ahlangabezane nezidingo zokusebenza ezikhethekile.
IV. Izithiyo Nezinkinga Zokusebenzisa
1. Izindleko kanye Nezomnotho
• 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).
• Ukukhathazeka Ngomthamo Wokungeza: Ukusetshenziswa ngokweqile kungaholela ekusakazeni okweqile kwamapowder, kuthinte ukunambitheka kokudla (njengokuthi kube ne-graininess uma kukhishwa ubisi lwempuphu).
2. Imithetho kanye Nokuhambisana
• Izithiyo Zesifunda: E-European Union, umkhawulo omkhulu wokusetshenziswa kwe-silica (E 551) emunyu wetafula ngu-5 g/kg, futhi amamodeli athile e-Evonik adinga imvume eyengeziwe ngenxa yezinkinga zendawo yephakethe.
• Izingozi Zokuhlangana: Ukuxhumana isikhathi eside nezinto ezinamandla ezimuncu noma eziphakeme kunganciphisa ukusebenza kokumunca, ngakho-ke kufanele kwenziwe izivivinyo zokuhlangana kuqala.
3. Ukulawulwa Kothuli
• Izinkinga Zokukhiqiza: Ubukhulu obuphansi (50 g/L) be-AEROSIL® buchaphazela ukukhiqizwa kokuthuliswa, kudinga imishini yokukhipha uthuli ezindaweni zokusebenza ezihlanzekile.
