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.
