In September, MicroVal granted certification for Non-Fermenting Total Viable Count (NF-TVC). NF-TVC is a series of Soleris manufactured by Neogen. NF-TVC detects total viable count at a threshold of 10 cfu per gram across a wide variety of food products.
The NF-TVC vial, containing 9 mL of broth, is designed for dilute-to-specification monitoring in diverse food matrices. As microorganisms grow in the medium, the carbon dioxide produced diffuses through a membrane into a soft agar plug with a dye indicator, resulting in a color change that is analyzed by the Soleris® instrument.
The detection time correlates with the contamination level, allowing for quicker results with higher levels of contamination. This validation aims to establish a rapid screening method for increased throughput in monitoring various food products, thus reducing both analysis time and time to results.
Campden BRI conducted the validation study in accordance with ISO 16140-2:2016, using ISO 4833-1:2013 as a reference method. The study encompasses a broad range of food categories, including dairy, fishery products (raw and ready-to-cook), fresh and processed produce, multicomponent foods, and meat and poultry products (raw and ready-to-cook).
The certificate and the detailed summary report, number 2022LR113, are available on our website.
