Geneius microID assists soft drinks producers

Geneius Laboratories Ltd. are working with a significant number of soft drink producers across Europe to precisely identify yeast, mould and bacterial contaminants within products, across processes and through supply chain. These contamination issues are particularly prevalent in soft drinks where fruit juices and/or extract are added to mixtures which generally do not suffer from a high proportion of spoilage issues due to a relatively low pH, low oxygen and nutrient levels.

The technology used by the drinks manufacturers to identify contaminants is Geneius microID, a ‘Gold Standard’ methodology of 16S/28S rRNA gene sequencing. This methodology is being readily adopted due to the accuracy of the detection, comprehensive databases which assist identification and the invaluable technical support and expertise that Geneius provide as part of the service.

Once identified, the type of microbe causing the spoilage can determine the reason behind the contamination and can rapidly be traced across processes and supply change. For example, there are certain osmotolerant yeasts that are well adapted for growth in soft drinks (Dekkera spp. used in the wine and brewing industries and found on the skin of fruit and Zygosaccharomyces spp. found in high sugar products such as dried fruit and syrups). These organisms can cause spoilage from as little as one organism in a container. They are slow growing and the spoilage may not arise until a few weeks after production. They can also resist weak acid preservatives such as benzoic acid. If these organisms are causing spoilage they may well have been introduced by the addition of a fruit pulp or juice and may not be process related. However other yeasts such as Candida spp. or Saccharomyces cerevisiae may contaminate the product through loss of function in processing, for example pasteurisation failure, addition of oxygen or poor hygiene.

Geneius microID provides our partners with the security that they have an identification service which is the most accurate and robust accredited microbial speciation service available. In product spoilage issues, the resolution and corrective actions required are always extremely time and cost critical. Our service not only identifies the contaminant precisely, through accompanying Geneius technology and support the contaminant strain can be rapidly traced through the production or cleaning process and ultimately back through the supply chain.
