In controlling & preventing the spread of food borne problems, speed and accuracy in microbiological testing are among the few most demanded criteria by the food safety industry.
As a result, these factors are one of the primary qualities of many scientific food techniques for microbiological testing & analysis this represent the complete focus of regular innovation and improvement.
Let’s take an example; getting real-time results related to the presence of potentially harmful microbiological impurities in food matrices has become a unfortunate reality in recent years, although it is with some limitations. This is completely in contrast with conventional & culture-based techniques which often needs several days to process it, Hence delaying all decisions related to the safety of food products and whether the further investigations are required or not.
Some of the other steps taken that will continue to have a significant effect on microbiological testing for food safety test includes:
- Culture-based tests like enzyme-linked immune –o-sorbent assay (ELISA) methods and diagnostic test kits for bacterial infections & microbial toxins. These immune-o-logical assay techniques completely rely on antigen-antibody which binding offers a very high degree of specificity and accuracy. They are eventually reduced dramatically by the time they are needed to obtain results, especially when they are compared to conventional enrichment and plating techniques
- Biosensor-based technique is the state at which these microbiological testing methods are also able reflects important achievements in the area of real-time food safety testing. Biosensors are the devices for infection detection which typically acquire 3 required elements, including a biological capture molecule, a method of converting the captured molecule-target interaction into a signal and a data output mechanism. Albeit biosensor-based techniques are currently are seeing only for limited use in a food safety test, they offer the complete advantages of real-time detection, portability and multi-infection detection in both laboratory and field environments.
- DNA-based fingerprinting techniques which are used for assessing the safety of food have made some tremendous progress and will continue it’s effort to become even more sophisticated with time. One of the most important advantages of DNA-based assays in the detection of food borne infections is their very high degree of specific pointing; they detect fixed, nucleic acid sequences in the target organism by hybridizing them into short synthetic olig-o-nucleotides that complement the specific nucleic acid type of assay. Automated polymerase chain reaction aka PCR based technology shows one of the quickest developing DNA-based analytical approaches often used in finding out food borne infections. Techniques which are based on PCR type technology offers very high specificity and extremely frequent turnaround times, making them an absolutely popular as less expensive test methods and instruments are often introduced for commercial type of use.
Regular improvements in PCR and other DNA fingerprinting techniques will add to the table of complete scientific technologies which are available to figure out food borne infections and microbial toxins. These and some advanced technologies which can facilitate the more quick determination of whether microbiological hazards exist or not, as well as it will also tell you at what point they may have been introduced into the current food supply chain.
