Protocols /Techniques Followed
- Conventional Methods
Enumeration Of Spoilage Microbes
Micro-organisms are ubiquitous in nature. Quality and shelf life of any product depends on presence and nature of micro-organisms contained in it. Under favourable conditions these micro organisms proliferate and result in loss of product quality. Microbiological monitoring is an essential part of quality control. ITL labs plays an important role in testing and certification.
- Standard Plate Count
- Coliform / Faecal Coliforms
- Psychrophilic and Thermophilic
- Aerobic and an-aerobic spore formers
- Rope Spore Count
- Anaerobic Bacteria
- Sulphite Reducing Bacteria
- Sulphur and Iron Bacteria
- Yeast and Moulds
Residual Anti-Microbial Substances
Food-producing animals are given antimicrobial drugs for prevention of disease and for their well being. The residues of these antimicrobial drugs remain in and on the body of the animals.
Following anti-microbial residues are being tested at ppb levels using ELISA techniques.
- Nitrofurans etc .
Bacteria produces Enterotoxins as a part of their metabolic activities. Some of them are heat labile while others are heat stable in nature. Even severe food processing treatments can not eradicate these toxicants and may result in food intoxication.
SRI undertakes testing of the following Enterotoxins in food and food products.
- Bacillus cereus Diarrhoeal enterotoxins
- Staphylococcal enterotoxins
Mycotoxins are carcinogenic, highly toxic metabolites of fungi like Aspergillus, Fusarium and Penicillium. They are toxic even in trace quantities
- Aflatoxins -Aflatoxin B1, B2, G1, G2, M1
- Deoxynivalenol (Vomitoxin)
- Ochratoxin A
- T-2 toxin etc.
Monitoring of Indoor Air
ITL labs carries out air-monitoring studies for presence of microbes. Services are provided in the following areas
- Storage Godowns
- Food Processing/Packaging Areas
- Clean Rooms/Clean Air Devices
- Operation Theatres and Intensive care units in hospitals
Nanotechnology In pharmaceutical, herbal and cosmetic formulations, various anti-microbial substances are added to arrest microbial activity and extend shelf life of the products. The effectiveness of these substances are evaluated as per USP protocols. Selection of challenge micro-organisms include gram positive and gram negative bacteria, spore formers, yeast and fungi.
The Phenolic and non-phenolic type disinfectants are being tested for their germicidal value as per National and International protocols.
