L-Cysteine ​​Monohydrate Powder – High-purity food-grade sulfur-containing amino acid (CAS 7048-04-6) a versatile ingredient for dietary and baking applications

L-Cysteine ​​Monohydrate is a compliant, food-grade, bioactive sulfur-containing amino acid ingredient. It is produced through a process involving biological fermentation and purification, precision recrystallization, monohydrate stabilization, and aseptic low-temperature drying and screening. It meets national standards for food additives and cross-border dietary amino acid ingredients. The product appears as a pure white, fine crystalline powder that is dry, free-flowing, and free from clumps, off-odors, or impurities. It exhibits excellent water solubility—dissolving rapidly and clearly in cold water without precipitation or easy recrystallization—and possesses stable physicochemical properties and strong reducing capabilities. It withstands standard low-temperature processing, resists hydrolysis and degradation, and offers exceptional formulation compatibility. As a highly active sulfur-containing monomeric amino acid, it features a crystalline monohydrate structure, mild properties, and ultra-low impurity levels, making it suitable for dietary formulations, food baking, and various scientific research applications. Produced without organic solvent residues, pigments, preservatives, artificial adulterants, industrial waste blending, or harmful additives; features high raw material purity. Ideal for use in compound amino acid powders, solid beverages, baking improvers, and dietary tablets.Basic Product Specifications****Product Name: L-Cysteine ​​MonohydrateEnglish Name: L-Cysteine ​​Monohydrate (Food Grade)CAS No.: 7048-04-6Source: Purified via biological fermentation; sterile refined monohydrate obtained through recrystallization.Grade: Food-grade, high-purity amino acid.Appearance: Fine, pure white crystalline powder.Main Components: L-Cysteine ​​Monohydrate ≥99%; trace crystalline matrix; active sulfur-containing components.Mesh Size: 80–100 mesh (fine texture; easy to dissolve and blend).Characteristics: High food-grade purity, high activity, strong reducing properties, rapid water solubility, low hygroscopicity, stable properties, broad compatibility, and batch-to-batch consistency.Applications: Amino acid nutritional blends, solid beverages, baking improvers, meal replacement powders, DIY nutritional ingredients, scientific research, and food fortification.Compliance: Food-grade amino acid raw material; free from additives and adulterants; compliant for cross-border trade.Storage & Shelf Life: Store in a sealed, cool, dry place away from light; 24-month shelf life.Scope of Application1.

The powder features fine crystals that dissolve rapidly in both cold and hot water, resulting in a clear solution without precipitation or residue. It exhibits excellent compatibility, blending seamlessly with various nutritional powders, amino acids, vitamins, and dietary ingredients; it remains stable and resistant to decomposition during both ambient and low-temperature food processing. Add the precise amount required by the formula and stir thoroughly until uniform; it is compatible with standard processes such as powder blending, beverage formulation, baking, and mass food production.Storage InstructionsStore in a sealed container within a cool, dry, well-ventilated, and clean environment, away from high temperatures, humidity, and direct sunlight. As an active amino acid powder in monohydrate crystalline form, it is slightly hygroscopic; high humidity can cause clumping and reduced flowability, while strong light and high temperatures may lead to oxidation, loss of activity, discoloration, and degradation of active ingredients. Do not store alongside materials that are odorous, oxidizing, or corrosive. Reseal immediately after use to exclude air and moisture, preserving the material's dryness and the stability of the amino acid's activity, thereby ensuring consistent purity and quality across batches.Important Notes1. This product is a food-grade amino acid dietary raw material—not a finished food product or medication. It should not be consumed directly in large quantities and is intended solely for compliant use in food formulations and scientific research.2. The powder is fine and odorless; it is recommended to wear a mask and gloves during handling to prevent dust inhalation or direct skin contact. 3. Please strictly adhere to food compliance standards; add the product according to the specified formula ratios, and do not exceed the permitted scope or dosage.4. Individuals with sensitivities to sulfur metabolism, a frail constitution, chronic illnesses requiring medication, or those who are pregnant or breastfeeding are advised to consult a healthcare professional before consuming products containing this ingredient.5. Store properly out of the reach of children and pets to prevent accidental ingestion.
