Yogurt Starter Culture (FD-DVS)

Description

1. Product Overview

Yogurt Starter Culture (FD-DVS) is a freeze-dried direct‑vat set (FD‑DVS) lactic acid bacterial culture formulated for industrial yogurt and fermented dairy production. Designed for consistent acidification and flavor development, it delivers rapid, predictable fermentation profiles across large-scale vats and continuous processing lines. The product’s key value is reproducible product quality (texture, tang, viscosity) with low contamination risk and simplified inventory management versus bulk fresh cultures. Strategically, it enables dairy manufacturers and co-packers to scale production, reduce cycle variability, and meet strict food-safety and regulatory requirements across global supply chains.

2. Key Specifications & Technical Characteristics

• Composition: defined blends of thermophilic and/or mesophilic lactic acid bacteria strains (e.g., Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus; optional adjunct strains such as Lactobacillus acidophilus, Bifidobacterium spp.).

• Viable cell count at packing: ≥1×10^10 CFU/g (strain-dependent; certified by batch COA).

• Purity / Grade: Food-grade, pharma-compatible manufacturing practices; free from pathogenic microorganisms (Salmonella, Listeria, E. coli negative per batch testing).

• Form: Freeze-dried (lyophilized) powder; free-flowing.

• Color/Appearance: off-white to beige fine powder.

• Particle size: typical D50 in the 50–200 µm range (process-dependent).

• Moisture content: ≤4% (to ensure stability).

• Bulk density: 0.45–0.65 g/mL (typical; lot-specific values on COA).

• Activity/Stability: Maintains declared viability for stated shelf life when stored under recommended conditions.

• Shelf life: 12–24 months at -18°C to 4°C (strain-specific; see product label and COA).

• Storage: Cold chain recommended; short-term transport at ambient acceptable with validated stability data.

• Packaging options: multi-layer foil sachets (5 g–1 kg), vacuum-sealed drums (10–25 kg), 20 kg sealed pails, or bespoke bulk packaging for big bags/IBC. All packages include lot number, expiry, and COA traceability.

• Regulatory documentation: Certificate of Analysis (COA), Certificate of Origin (COO), HACCP/FSMS declarations, strain dossiers and allergen statements available on request.

3. Core Industrial Applications

• Primary industries: large-scale dairy processors, yogurt co-packers, functional dairy/nutraceutical manufacturers, food service/ingredient suppliers, and contract manufacturers producing set, stirred, Greek, and drinkable yogurts.

• Operational use cases: direct inoculation in vat or high‑shear incubation, continuous line fermentation control, starter renewal for pilot and scale-up batches, tailored formulations for low‑fat or high‑protein products, and synbiotic/fortified yogurt production.

• Performance advantages vs alternatives: freeze-dried DVS provides immediate, accurate dosing and rapid activation without repeated propagation, reducing contamination risk and labor. Compared with bulk liquid starters, FD-DVS offers longer shelf life, simplified cold-chain management, and consistent starter strength for predictable acidification curves and texture development.

• Commercial relevance: enables tighter process control (shorter incubation windows, consistent pH endpoints), higher throughput, and lower batch rejection rates—translating to improved yield, reduced downtime, and predictable sensory outcomes for branded products.

4. Competitive Advantages

• Quality consistency: manufactured under controlled fermentation and lyophilization with batch COAs and traceable strain provenance to ensure repeatable functionality.

• Supply reliability: scalable production with backed safety stock, scheduled manufacturing slots, and contingency supply agreements to support continuous industrial requirements.

• Logistics capability: multi-modal distribution with validated cold-chain options, export-ready documentation, and configurable packaging for direct-to-factory delivery.

• Price competitiveness: tiered pricing for volume contracts, long-term supply agreements, and cost-in-use transparency (improved yield and reduced reject rates lower total ingredient cost).

• Sustainability: optimized production processes with waste minimization; lightweight, recyclable packaging options and reduced cold-chain fuel usage for validated ambient-stable lots.

• Technical support: application and scale-up assistance from industrial dairy technologists, fermentation curve optimization, dosing recommendations, and shelf-life validation support. Full documentation (COA, stability data, handling guides) provided for QA teams.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT.

• Loading capacity (MT per container): Standard 20-foot container up to 18–20 MT (packaging- and palletization-dependent); 40-foot container up to 24–26 MT depending on pallet configuration and packing format.
