Alicyclobacillus spp. in fruit juice concentrate and beverage compounds
Parameters: Alicyclobacillus qualitative (3 samples fruit juice concentrate and beverage compounds)
article number: 2010493
Description: In the field of cooperation we developed and established PT schemes in the matrix fruit juice concentrate and beverage compounds for the fruit juice industry. Potential microbiological spoiling agents belong to different germs like yeasts, moulds, lactobacilli or acetic acid bacteria. Alicyclobacillus is very important for the production and spoilage of fruit juices because it is able to form endospore to be heat-stable.
Category: microbiological testing microbiology nonalcoholic beverages
Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation.

anaerobic mesophilic spores tinned food
Parameters: anaerobic, mesophilic spores qualitative (3 samples)
article number: 2010950
Description: Thermoresistent spores of anerobic spore-forming bacteria usually occur ubiqious reaching the foodstuffs during the production process and can lead to taste changes and spoilage. These bacteria are able to survive the pasteurisation step using their heat-stable spore-form. Some of their pathogen representatives produce enterotoxins causing regurgitation or diarrhoea.
Category: microbiological testing microbiology cans, canning, glass
Accreditation: This proficiency test is within the scope of the A2LA and the DAkkS accreditation.
