Modified Plate Count Agar (MPCA) – Dairy Testing Medium for Total Counts & Psychrotrophs | 250g
Industry-Standard MPCA Medium for Comprehensive Dairy Microbiological Analysis
Precisely formulated Modified Plate Count Agar meets rigorous dairy testing requirements for accurate enumeration of total viable counts, psychrotrophic microorganisms, and aerobic spore-forming bacteria in milk and dairy products. With optimized skim milk powder integration, this medium simulates dairy matrices for reliable colony development.
Critical Dairy Testing Applications:
🥛 Total Viable Counts: Gold-standard medium for dairy product microbial load assessment
❄️ Psychrotroph Detection: Supports growth of cold-tolerant spoilage organisms
