Imikhiqizo Izici kanye Nezici Zobuchwepheshe

1.1 IziNhlobonhlobo Zezinto Zomzimba

High Purity: PQ food-grade silica typically contains ≥99% SiO₂, complying with national standards such as GB 25576-2020. It appears as a white, free-flowing powder with uniform particle size distribution (e.g., the Gasil series has an average particle size of ~6.8 μm), effectively preventing particle aggregation.
Mesoporous Structure: I- mesoporous design inika amandla kwayo nge- high specific surface area (isb., 185 m²/g njengoba kukalwa ngendlela ye-BET) kanye ne- oil absorption value ye- 280–300 g/100g. Ingakwazi uku- adsorb excess moisture kanye ne- oil ezithelweni, yakha i- barrier ukuvimbela i- caking.
Chemiese Inertheid: Ooplosbaar in water en die meeste sure, reageer slegs met hidrofluoriese suur en sterk alkalies, wat verseker dat daar geen interaksie met voedselkomponente is nie en die oorspronklike geur en voeding behou word.

1.2 Ukufaneleka Kwenqubo

Low Dust Emission: With a high bulk density (e.g., Gasil AB905 has a bulk density of 6.2 lb/ft³), it reduces dust generation during processing, meeting modern clean production requirements.
Thermal Stability: Maintains structural stability at high temperatures, suitable for processing scenarios like baking and frying.

Izindawo Zokusebenza Nokuhlaziywa Kwezisebenzi

2.1 Core Application Scenarios

2.1.1 Uthango lweMazi kunye neZithako zokutya

Milk Powder: Adding 1–3% PQ silica significantly improves flowability and prevents caking caused by moisture absorption. For example, in instant milk powder, its porous structure adsorbs moisture, keeping the product loose under 40℃/75% RH conditions.
Nutritional Fortifiers: Njengomthwali wezivithamini, ama-probiotics, njll., ivikela izingxenye ezithambile ekuphendukeni nasekwehliseni, ikhulisa impilo yeshelufu.

2.1.2 Izinongo nezokudla ezisheshayo

Powdered Flavors/Soups: Ngokufaka iziphuzo ze-liquid, iguqula zibe uthuli olukhululekile ukuze kube lula ukukala nokuhlanganisa. Isibonelo, ukufaka u-2–5% PQ silica ku-chicken bouillon kuvimba ukuhlanganiswa futhi kuthuthukisa ukusabalala.
Instant Coffee/Beverages: Iphucula ukuhamba kwezakhi, yehlisa ukuhlanganiswa ngesikhathi sokupheka, futhi ibamba umswakama owengeziwe ukuze igcine ukuzinza komkhiqizo.

2.1.3 Gebak en Graanprodukte

Uthuli/Umxube Wekhekhe: Uvimbela ukuhlanganiswa ngenxa yokushintsha kokunwetshwa, uthuthukisa ukusebenza kokucubungula idough, futhi uthuthukisa umumo wemikhiqizo eqediwe.
Puffed Foods: Njengomphakathi wokulwa nokubamba kanye nomkhiqizo, unciphisa ukujolisa ekupakisheni futhi uthuthukisa ikhwalithi yokubukeka.

2.2 Iziphakamiso Eziqhamukayo

2.2.1 Iifuno ezisekelwe ezithelweni

In plant proteins (e.g., soybean protein powder), PQ silica adsorbs oil, prevents layering, improves solubility, and enhances product stability.

2.2.2 Iifuno eziSebenzayo

Used as a carrier for functional ingredients like dietary fiber and probiotics, enhancing their stability during processing and storage.

Compliance and Quality Assurance

3.1 Iziqinisekiso Zokulawula

Domestic Standards: Complies with GB 25576-2020 National Food Safety Standard for Food Additive Silica, allowing use in dairy products, seasonings, and other food categories with a maximum addition of 15–20 g/kg.
International Certifications: Some grades are certified by FDA (21 CFR 172.480) for export foods, and also comply with EU EFSA (E 551), Kosher, and Halal standards.
Special Compliance: While PQ products have limited use in table salt under 2025 regulations, they remain compliant in other food sectors.

3.2 Uhlelo Lokukhiqiza

Certified by ISO 9001 quality management system, with some production lines complying with GMP standards to ensure batch-to-batch consistency.
Exportprodukte erfüllen die Anforderungen an den Marktzugang im internationalen Handel, wie z.B. die russische EAC-Zertifizierung.

Differentiated Advantages vs. Competitors

4.1 Ukulinganisa KweMisebenzi

Anticaking Efficiency: PQ silica’s oil absorption (280–300 g/100g) is higher than some competitors (e.g., Grace SYLOID 63 FP’s 200 g/100g), performing better in high-humidity environments.
Processing Compatibility: Its high bulk density (e.g., 6.2 lb/ft³ for Gasil AB905) facilitates mixing with other excipients and reduces electrostatic adsorption.

4.2 Isebenziswano Kwezindleko

High adsorption capacity reduces usage, with lower overall costs than traditional anticaking agents (e.g., sodium aluminosilicate).
Low dust emission minimizes processing loss and improves production efficiency.

Ukusebenzisa Izeluleko Nezinyathelo Zokuphepha

5.1 Dosage Control

Recommended addition: 0.5–3%, adjusted according to food type and environmental humidity. For example, milk powder in high-humidity regions may require 2–3% addition.

5.2 Ukufaniswa

Avoid prolonged contact with strongly acidic or alkaline substances to prevent affecting adsorption performance.
Kan gebruik word in kombinasie met eksipiënten soos magnesiumstearaat en mikro-kristalliene selulose, maar kompatibiliteitstoetsing is eers nodig.

5.3 Iimekozo zokugcina

Store in a sealed container in a dry, cool place to avoid moisture affecting flowability.
