Microbiological Testing requirement
Microbial contamination poses a significant risk to the Water, Environment and all type of Industries potentially leading to illnesses and jeopardizing consumer health. At N.S. Envirotech Laboratories, we understand the critical importance of microbiological testing in identifying and quantifying harmful bacteria, yeasts, Molds, and other microorganisms present in products. Our comprehensive microbial testing services serve as a vital defence against contamination, ensuring regulatory compliance and safeguarding your brand reputation.
Microbiological Analysis of Food Products
Microbiological analysis is performed to analyse the quality of product with respect to its microbiological aspects. Microorganisms can come into the product through air, water, raw material, packaging material and many other sources that can detoriate the product. Microorganisms are the main cause of disease and decaying of food products. Microorganisms may also cause the detoriation of plastics, polymers and stones. Microorganisms may be pathogenic (disease causing) and non-pathogenic (non-disease causing) depending upon their mode of action. Microbiological analysis carried out to enumerate the amount of microorganisms present in the product quantitatively and qualitatively. The category of food and their products analysed as follows:
Bakery and Confectionery Products
Beverages (Alcoholic / Non-alcoholic)
