Sensory testing recommendations

To comply with the general requirements of Article 3 of the EU Regulation 1935/2004 sufficient sensory inermess of the PCR PET products as food contact articles needs to be assured. Therefore appropriate sensory testing of food contact articles made from super-clean products is recommended. As worse case test conditions for this purpose, storage of the article in direct contact with water for ten days at 40 °C have been generally accepted. However, depending on the particular application, modified tests may be more suitable. 

Regardless of the official specifications for soybean oil and its products, the ultimate proof of the pudding is in the eating that is, sensory evaluation of the odors and flavors of soybean oil and its products is the ultimate method to assess oil quality and stability. Sensory evaluation cannot be replaced fully by any chemical or instrumental analysis, although some methods can correlate fairly well with sensory results. Sensory evaluation of oils usually is done by a panel of experts or a trained panel, and often the method recommended by the American Oil Chemists Society (300) is used. During the evaluation, the panel is asked to score the overall flavor quality, as well as the intensity of many individual off-fiavors. Although chemical and physical tests are more reproducible and less time consuming than sensory evaluations, oxidative rancidity and off-flavor evaluation of soybean oils are best done by sensory tests. Correlations established between sensory evaluation scores and... 

Organizing sensory testing with children practical recommendations... 

Toxicologic Data" and the "Workshop on the Effects of Pesticides on Human Health" which was organized by the Task Force on Environmental Cancer, Heart and Lung Disease) have recommended methods and test batteries that would detect sensory, motor, autonomic, cognitive and behavioral dysfunction. 

The following sections examine two processes associated with recmitment activities (i.e., job analysis, and realistic safety preview), and a range of selection predictors (application blank, applicant interview, cogiutive, physical, psychomotor, sensory/perceptual ability testing, personality testing, and attitude measurement) which an organization can use to help predict job applicant (new employee s) safety behavior, and overall their ability to work safely. Where appropriate, recommendations on how recruitment and selection processes can be used to improve new employee safety are discussed. Finally, this chapter examines how employees perceptions of organizational processes can be made more realistic. 

The system of primary interest as presented here is the sensory processor. Processing times associated with the motoric processor involved in the response are substantially less in normal systems. However, it is recommended that a given processor speed capacity be identified not onlyby the sensor subsystem stressed, but also by the responder (e.g., visual shoulder flexor information processor speed). This identifies not only the test scenario employed but also the complete information path. 

This section will present how to organize sensory evaluation testing with children, by considering legal issues and practical recommendations. 

Instruments that could be used to evaluate infant sensory competencies in studies on the developmental effects of adding new ingredients to infant formulas are shown in Table 6-11. Even though the instruments described in the table have not been specifically linked to CNS development, sensory functions tapped by these instruments clearly have specific associations with brain structure and function. While preferential-looking procedures to test visual function and visual reinforcement audiometry to test auditory function have not been used in studies with infants exposed to toxins, they have been extensively used in clinical studies. These two procedures are thus recommended as being state of the art in the behavioral assessment of visual and auditory function. They could be easily combined with the func-...
