SYLOID® Series: Multifunctional Food-Grade Silica
The food-grade silica products under W.R. Grace & Co. (U.S.) are mainly concentrated in three major series: SYLOID®, TRISYL®, and PER KASIL®, which are widely used in food processing, edible oil refining, nutritional supplements, and other fields. The following are the verified core models and their application scenarios:
SYLOID® Series: Multifunctional Food-Grade Silica
The SYLOID® series is Grace’s most representative food-grade silica product line, certified by the FDA (21 CFR 172.480) and approved by the European EFSA (E551). It is mainly used for moisture-proofing, anti-caking, flow improvement, and oil adsorption.
1. SYLOID® 63 FP
Properties: High porosity, low hygroscopicity, capable of adsorbing liquids 2.5 times its own weight.
Applications:
– Nutritional supplements: Used as an anti-caking agent for powdered vitamins and minerals to prevent caking and improve flowability.
– Seasonings: Used for moisture-proof treatment of salt, sugar, and spices to extend shelf life.
– Compliance: Meets FCC, USP/NF, and Japanese food additive standards.
2.SYLOID® 244 FP
Properties: A multifunctional excipient with moisture-proof, anti-static, and lubricating properties.
Applications:
– Tablets/capsules: Improves powder flowability and prevents sticking during tableting.
– Functional foods: Acts as a carrier to adsorb oils or liquid ingredients, forming stable solid dosage forms.
– Technical Advantages: Controllable pore structure, customizable adsorption capacity.
3.SYLOID® 72
Properties: Medium porosity, strong adsorption capacity (1.1 mL/g liquid).
Applications:
– Liquid foods: Adsorbs oils or flavor substances for stabilizing salad dressings and soups.
– Pet food: Prevents particle caking and improves processing efficiency.
– Compliance: Meets FCC, European E551, and Japanese D326 standards.
4.SYLOID® AL-1 FP
Properties: High specific surface area (200-300 m²/g), strong hygroscopicity.
Applications:
– Baked foods: Absorbs trace moisture to prevent starch retrogradation and extend shelf life.
– Dairy products: Used for anti-caking treatment of milk powder and cheese powder.
– Technical Parameters: Particle size of approximately 5-10 μm, suitable for ultra-fine powder processing.
TRISYL® Series: Silica Specialized for Edible Oil Refining
The TRISYL® series is specially designed for edible oil refining, certified by FDA GRAS. It is used to remove phospholipids, metal ions, and saponins, thereby improving oil quality.
1.TRISYL® 150 IE
Properties: High-purity synthetic amorphous silica (>99.9% SiO₂).
Applications:
– Enzymatic transesterification: Extends the service life of enzymes, replaces traditional hydrogenation processes, and produces zero-trans fat oils.
– Fish oil refining: Removes off-flavor substances and heavy metal residues.
– Environmental Advantages: Reduces wastewater discharge and meets sustainable production requirements.
2.TRISYL® 300
Properties: High adsorption capacity, capable of removing colloidal nickel and saponins.
Applications:
– Post-hydrogenation treatment: Used for removing nickel residues during vegetable oil hydrogenation.
– Biodiesel pretreatment: Adsorbs polar impurities to improve fuel quality.
– Safety: No crystalline silica, avoiding occupational health risks.
3.TRISYL® 450
Properties: Designed for animal fats (e.g., tallow), with high efficiency in collagen removal.
Applications:
– Animal fat refining: Improves oil transparency and reduces off-odors.
– Regional Availability: Mainly supplied to the Latin American market.
PERKASIL® Series: Food-Grade Precipitated Silica
The PER KASIL® series is certified by FCC and used for anti-caking and flow improvement in food additives and nutritional supplements.
1.PERKASIL® 1450
Properties: Low bulk density (0.10 g/cc), high flowability.
Applications:
– Seasonings: Prevents caking of salt and sugar, improving packaging efficiency.
– Protein powder: Improves powder flowability for easy metering and mixing.
– Technical Parameters: Particle size of approximately 10-20 μm, suitable for high-speed production lines.
2.PERKASIL® 2000
Properties: High hygroscopicity, capable of adsorbing moisture in the environment.
Applications:
– Baking premixes: Prevents caking and maintains powder stability.
– Pet food: Acts as a moisture-proof agent to extend shelf life.
– Compliance: Meets FDA and European E551 standards.
Other Related Products
1.SYLOBLOC® P 05
Properties: Synthetic amorphous silica, used for anti-blocking of food packaging films.
Applications:
– Fresh-keeping films: Prevents film blocking and improves processing efficiency.
– Compliance: Certified by FDA for food contact (21 CFR 177.1520).
2.SYLODENT® 753
Properties: Low-hardness silica, used as an abrasive in toothpaste.
Applications:
– Oral care: Gently cleans teeth and is compatible with fluoride components.
– Compliance: Meets FCC and European Pharmacopoeia standards.
