Sysmex Partec CyStain™ Reagent Kits for Food & Beverage Analysis
The Sysmex Partec range of reagent kits for the food and beverage industry represents a shift from traditional, time-consuming cultivation methods to rapid, objective digital analysis. By utilizing flow cytometry (FCM) and VIT® gene probe technology, these kits allow for the precise detection of spoilage organisms like Alicyclobacillus and Dekkera, alongside comprehensive yeast viability and population monitoring. This data-driven approach enables production managers to make immediate decisions, ensuring product stability, optimizing fermentation curves, and significantly reducing the time-to-market for sensitive oenological and beverage products.
Traditional plating methods can take days to yield results. CyStain™ kits, used in conjunction with flow cytometry, provide actionable data on microbial load and viability in a fraction of the time, supporting streamlined production workflows.

Viability Assessment
CyStain™ VitalCount
CyStain™ VitalCount is a specialized staining solution designed for the rapid and precise quantification of viable microorganisms in food and beverage samples. By utilizing flow cytometry, this kit enables the differentiation of metabolically active cells from debris and dead populations, providing actionable data for quality control and production safety.
Specifically designed for the quantification of viable bacteria and yeast in fruit juices. It allows for rapid product release by detecting contaminants in hours instead of days.
| Product Number | Product Name | Application |
| 05-5029 | CyStain™ VitalCount | Detection and quantification of viable microorganisms |
Microbial Differentiation
CyStain™ GramCount
CyStain™ GramCount is an advanced reagent solution for the rapid automated differentiation of Gram-positive and Gram-negative bacteria. Unlike traditional Gram staining which is labor-intensive and subjective, this flow cytometry-based kit provides objective, quantitative results in minutes. It is an essential tool for beverage quality control, enabling producers to quickly identify contaminant types and implement targeted corrective actions.
Used primarily in wine production to monitor malolactic fermentation by differentiating Gram-positive and Gram-negative bacteria.

| AL552895 | CyStain™ GramCount | Rapid differentiation of Gram-positive and Gram-negative bacteria |
Quality Assurance in Juices
FlowVit® Alicyclobacillus
FlowVit® Alicyclobacillus provides a rapid and highly specific solution for detecting Alicyclobacillus species, known for causing "off-flavors" in fruit juices and concentrates. By combining the specificity of VIT® gene probes with the speed of flow cytometry, this kit allows for the detection of guaiacol-producing bacteria much faster than traditional culture methods. This enables juice producers to identify potential spoilage early in the process, preventing significant financial losses and ensuring product integrity.

| 01150001 | FlowVit® Alicyclobacillus | Detection of Alicyclobacillus in fruit juices and concentrates |
Rapid Yeast Monitoring
CyFlow™ BrettCount
CyFlow™ BrettCount is a specialized reagent kit for the rapid, objective, and quantitative detection of Brettanomyces (Dekkera) yeasts in wine and cider. Unlike traditional plating methods that require up to 10–14 days of incubation, this flow cytometry-based solution provides accurate cell counts in minutes. It allows winemakers to monitor populations of spoilage yeasts in real-time, enabling immediate intervention to prevent the development of 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG) which can compromise the sensory profile of the product.
| Product Number | Product Name | Application |
| 05-6002 | CyFlow™ BrettCount | Rapid quantification of Brettanomyces yeasts |
Specialized Spoilage Control
FlowVit® Dekkera anomala
FlowVit® Dekkera anomala provides a cultivation-independent solution for the rapid identification and quantification of Dekkera anomala (formerly Brettanomyces anomalus). Specifically designed for the cider and wine industries, this kit targets viable but non-culturable (VBNC) cells that traditional plating methods often overlook. By utilizing VIT® gene probe technology, the kit ensures that only metabolically active yeasts are detected, preventing false positives from dead cell residues and providing an accurate assessment of spoilage risk in all production stages.

| 01150003 | FlowVit® Dekkera anomala | Specific detection of Dekkera anomala |
Fermentation Control
CyStain™ OenoYeast
CyStain™ OenoYeast is a specialized solution designed for the comprehensive analysis of yeast populations throughout the winemaking process. Optimized for flow cytometry, this kit enables rapid quantification and monitoring of yeast dynamics, ensuring precise control over fermentation stages and contributing to the consistent quality of oenological products.
| Product Number | Product Name | Application |
| 05-6001 | CyStain™ OenoYeast | Comprehensive analysis of yeast populations in wine |
Fermentation Quality Control
Yeast Control™ Viability
Yeast Control™ Viability is a specialized diagnostic kit for the rapid assessment of metabolic activity and membrane integrity in yeast cells. By providing a clear distinction between viable, damaged, and dead populations, this kit allows production managers to monitor culture health in real-time. It is a critical tool for ensuring consistent fermentation performance, verifying yeast pitch health, and troubleshooting production stalls in the brewing, oenology, and baking industries.
| Product Number | Product Name | Application |
| 05-6000-02 | Yeast Control™ Viability | Assessment of metabolic activity and cell viability in yeast |
Automated Microbial Counting
CyStain™ OenoCount
CyStain™ OenoCount is a high-throughput solution for the rapid quantification of total microbial counts in oenological samples. This kit is specifically designed to replace time-consuming manual microscopy and traditional plating, providing accurate results in minutes. By enabling real-time monitoring of microbial loads during various stages of vinification, OenoCount helps winemakers ensure product stability and prevent microbial spoilage before it impacts the organoleptic properties of the wine.
