The October issue of Food Technology contained an excellent overview of the advantages and disadvantages of outsourcing. “A Rational for Outsourcing” by Jennifer Patterson and Stephen Haas discussed the steps to take for successful outsourcing. As companies focus on their core business, they are finding that picking appropriate outsourcing partners allows them to remain competitive. While some food companies are struggling to remain competitive by outsourcing testing, some laboratories are finding that good business opportunities in analytical services are to be found, provided the lab can deliver results faster than the competition.

LABORATORYOutsourcing of testing allows companies to focus on their core activities while getting the benefits of economies of scales and overhead reduction. Those seeking an outside partner should be aware they will lose in-house skills and expertise, control, confidentiality to some extent, and the ability to monitor costs. A rule of thumb is that companies should not outsource their core business or critical processes.

Filtration device for quantitation of microorganism contaminated liquids.
U.S. patent 5,979,668, filed 6/23/1998, issued 11/9/1999 to J. Kane et al., assigned to the Pall Corp. Describes the use of a disposable filtration capsule with a non-occluded membrane filter element in the place of a standard spiral wound cartridge. This allows for the more rapid and quantitative filtration, recovery, and quantitation of microorganisms in liquid, particularly surface waters, well water, tap water, and others. The costs of measuring contamination by microorganisms such as Giardia and Cryptosporidium is lowered significantly while increasing the accuracy and dependability of the measurement.

Products & Literature
in a variety of sample types may be accomplished with the SMART System5. The microwave-based system continuously weighs the sample during the drying process. The constant monitoring of the weight loss during drying allows the system to know the precise time the sample is dry to ensure complete dryness and prevent burning. A built-in shield controls airflow in the cavity to provide a stable environment for accurate balance readings. The system can analyze a variety of samples including solids, powders, or slurries as well as low- to high-moisture samples. The system is said to be able to determine moisture/solids in very high carbohydrate products such as frostings and corn syrup; the temperature control feature allows the accurate heating of heat-sensitive samples. The system stores 100 methods and 300 sample results. These results can be selected to perform various statistical analysis including average of results, standard deviation, minimum and maximum range, and graphing in reference to target values. A flame detector senses open flame in the system cavity to allow the safe testing of flammable samples. An optional exhaust system allows the safe removal of flammable solvents.

SALMONELLA TESTING may be accomplished with the use of the Dynabeads® anti-Salmonella test kit. This product allows for the immunomagnetic selective enrichment of Salmonella directly from pre-enrichment broths. The method is said to save 24 hr of testing time. The method replaces the use of selenite or tetrathionate selective enrichment broths. Isolated Salmonella colonies or negative results are said to be achieved in 48 hr from receipt of a sample. The Dynabeads are uniform, superpara-magnetic microspheres (2.8 microns in diameter) with affinity purified antibodies on their surface. When incubated with a sample, the beads will bind their target bacterium, forming a bacterium:magnetic bead complex. This complex is separated from the heterogenous sample by performing the test in a magnetic test tube rack. The isolated and concentrated complex can then be cultured on any selective culture medium.

MOISTURE ANALYZERS, the MA50 and MA100, allow the user to perform high-resolution weighing for moisture analysis. With these units, the heating unit may be changed to suit a particular application. For example, the ceramic radiator is ideal for fast and uniform heating, and prevents overheating of specific areas of a sample. While the alternative choice of a halogen lamp unit provides the flexibility of an easy-to-regulate heat source. The incorporation of a high-resolution weighing system for low-level moisture determination is made possible by the novel design of the motorized heating unit. This permits optimal access to the sample chamber, while minimizing the vibration caused by opening and closing that can interfere with the weighing system. The 0.1 mg resolution provided by the MA100, with a weighing capacity of 100 g, is equivalent to the accuracy of an analytical balance.
