Fast Allergen Analysis

Fast Allergen Analysis

Allergen detection includes milk, peanuts, egg, soy and gluten. Turn around time is as soon as same day.

Rapid Bacterial Testing

PCAS rapid microbial identification methods target the broad spectrum of critical pathogens like E.coli O157:H7, Listeria monocytogenes, Salmonella (over 2,000 serotypes), etc. In addition to microbial identification, our laboratories can analyze also for the presence of toxins (e.g. Staphylococcal toxins, Aflatoxins, etc).

Principle:

Based on Enzyme immunoassay (EIA) and immunoprecipitate, PCAS’ methods consist of incubating samples in an enrichment media and then transferring aliquots to microplate wells chemically treated to identify target microorganisms. Changes in light absorbance are measured with the assistance of a microplate reader. Our multi-test format sample handling system allows us increased flexibility and high sample throughput. Internal controls (positive and negative controls) are run with each sample lot to ensure the accuracy of results.

Results Turn Around Time and Food Matrixes:

Next day results are available for a number of food matrixes including Almonds, Cake Mix, Coconut, Dried Egg Powder, Dry Cheese, Fish, Frozen Liquid Egg Yolk, Green Beans, Ice Cream, Liquid Instant Formula, Liquid Milk, Milk Chocolate, Milk Protein, Pasta, Pepper, Poultry Meal, Raw Ground Chicken, Raw Ground Pork, Raw Shrimp, Surimi, etc.

Approvals:

PCAS’ methods are AOAC and AFNOR approved.

PCAS has recently acquired a novel LECO protein analyzer that delivers results in less than 3 minutes. The instrument uses the Dumas method where samples are burnt in pure oxygen and protein residues are transformed into N2. Nitrogen gas is then measured by a TCD detector and converted to protein % using an applicable conversion factor, i.e. 6.25.

Principle:

The technique was first introduced by the French Chemist Jean-Baptiste Dumas and has been recently automated to allow the rapid analysis of protein by methods AOAC 968.06 and 992.23. Results correlate well with the traditional Kjeldahl analysis without the need of lengthy digestions or harsh chemicals.

Samples with little or no preparation are weighed into a tin cup, sealed and then loaded into the instrument. The tin cup containing the sample is flushed with Helium to remove atmospheric nitrogen and then dropped into a furnace containing pure oxygen where they combust at 950°C. Food samples are then converted to Nitrogen oxides, H2O vapor and CO2. Combustion gases are pumped through a thermoelectric cooler to condense water and then flushed through scavenger columns where CO2 is removed. Finally, the remaining Nitrogen oxides are reduced to N2 by means of a copper catalyst and then quantitatively measured by means of a TCD detector.

The entire system is controlled by a powerful microprocessor which utilizes icon driven software and an interactive touch screen providing the perfect balance between advanced capabilities and user friendly operation.

Automatic diagnostics, data handling capabilities, curve fitting calibration, report generation, gas conservation and programmable wake up are a few of the advanced capabilities offered by the system designed to enhance laboratory efficiency and flexibility.

Results Turn Around Time and Food Matrixes:

The new protein Matrices analyzed include bakery products, grains, meats, dietary fiber, pet food, seeds, plants and processed foods.

Approvals:

The methods used have received approval from the AOAC (Association of Official Analytical Chemists), AOCS (American Oil Chemists Society), and AACC (American Association of Cereal Chemists).
