The sensitive
molecular test will be made available soon to the international market.
The assay
for Pennsylvania-based Victory Brewing will be called Veriflow brewPAL and be
developed with Invisible Sentinel’s Veriflow technology by the end of this year
or start of 2015. Veriflow brewPAL will enable on-site detection of Pediococcus and Lactobacillus, which can affect the taste of beer by producing
lactic acid.
Current
testing methods are time-consuming, meaning corrective measures are delayed -
the result for brewers can be spoilage, higher production costs and delayed
product release.
Industry issues: Nick Siciliano, Invisible Sentinel co-founder
and CEO, said the process involved seeing what the firm was doing for quality
control and monitoring and a market analysis and feasibility study.
“Pediococcus and Lactobacillus are among the biggest issues, they are environmental
contaminants which come in on grain and can become resident in the facility and
if they are mixed with the product lactic acid can form in the final product
and spoil the beer in the bottle,” he told FoodQualityNews.com.
It is a
critical issue, in bottles more as they sit in room temperature or higher in
shipment, and then the warehouse for six months before drinking, for other
things such as kegs they are kept cold so it is less of a problem. The
agreement anticipates that the assay will be made available to the
international market.
Paradigm shift: Siciliano said it will streamline workflow
collection, allowing for quicker product release and it would cut down on time
to result. The test will offer same day turnaround and accuracy is in the same
region as with our work in the food pathogens space with close to 100%
specificity. The molecular test adds a level of sensitivity, as now they are
doing plating so they can be waiting seven days to possibly get a presumptive
positive and they have to sit on the bottles while they check. If it comes back
positive they have to scrap the product, this is a preventative tool to
remediate, detect and get results quickly, it is a paradigm shift as they have
the technology but no option to use it due to time.
Invisible
Sentinel has also developed Veriflow LS for Listeria
species, Veriflow SS for Salmonella
species, VeriflowCA for Campylobacter,
and Veriflow LM for Listeria
Veriflow
assays for E.coli O157:H7 and Shiga
toxin-producing E. coli (STEC) are
pending approval by the Association of Analytical Communities (AOAC).
