Overview
Cream is a versatile dairy product derived from the fatty layer of milk. It is classified by fat content, ranging from light cream (18-30%) to heavy cream (36-40%). Its rich texture and emulsifying properties make it indispensable in food preparation, particularly in baking, desserts, and sauces. Industrial procurement of cream requires attention to fat percentage, pasteurization methods, and shelf life. B2B buyers often source it in bulk from dairy processors or specialized distributors, ensuring compliance with food safety standards.
Physical and Chemical Properties
Cream's viscosity and stability depend on its fat globule structure and homogenization process. The product typically contains 55-65% water, with the remainder being milkfat, proteins, and carbohydrates. Its emulsion stability is critical for applications like whipped toppings. Under refrigeration, cream thickens but remains pourable. Freezing may cause separation, requiring rehomogenization. The pH ranges from 6.5 to 6.7, making it slightly acidic. Heat treatment (e.g., ultra-pasteurization) extends shelf life but may alter flavor profiles.
Main Applications
In the food industry, cream serves as a key ingredient for texture enhancement and flavor carrier. Commercial bakeries use it for ganache, buttercreams, and custards. Food manufacturers incorporate it into ice cream, soups, and ready meals for richness. Non-food applications include cosmetic formulations (moisturizers, lotions) where its fatty acids provide emollient properties. Pharmaceutical creams may use medical-grade lactose-free variants as bases for topical drug delivery.
Safety and Storage
Cream is highly perishable due to its water activity and nutrient content. Commercial storage requires strict temperature control (≤4°C) to prevent bacterial growth like Listeria. Ultra-pasteurized cream lasts 2-3 weeks unopened, while sterilized variants may keep for months. Transport should use refrigerated logistics with temperature monitoring. Bulk containers (20L bags-in-box) reduce contamination risk versus open pails. Always check for off-odors or curdling before use in sensitive applications like dairy-based sauces.
B2B Procurement Guide
When sourcing cream wholesale, specify fat content (e.g., 35% for whipping, 18% for coffee creamers). Verify pasteurization methods—HTST (high-temperature short-time) preserves flavor better than UHT. Request Certificates of Analysis (CoA) for microbiological counts and butterfat tests. Consider regional suppliers to minimize transport time. For international procurement, frozen or aseptic-packed cream may be preferable. Negotiate contracts with clauses for quality rejection and batch testing, especially for large-volume purchases exceeding 1,000 liters monthly.
