Consumers data analysis

In the Moisio-Heikonen paper another, more elaborate but also more time-consuming data-analysis method was used - as detailed in Fresenius]. Anal. Chem. 354 (1996) 271 - but that is immaterial here. It is with fast and inexpensive methods such as these that enough samples can be analyzed to maintain a consistently high quality of the dairy products during the winter months.

Natural ingredients based lipstick formulations have been prepared. The effects of the natural waxes, oils and solvent compositions on the viscosity and melting point of the lipstick have been studied. The result indicates that the viscosity and melting point of the lipstick can be manipulated by changing the composition of natural candelilla wax, camauba wax and beeswax in the formulation. Another important lipstick characteristic, which is hardness, will be studied. Consumer acceptance towards the product will be investigated. Finally, by relating the consumer data and instrumentation analysis, optimisation process will be conducted. 

The determination and analysis of sensory properties plays an important role in the development of new consumer products. Particularly in the food industry sensory analysis has become an indispensable tool in research, development, marketing and quality control. The discipline of sensory analysis covers a wide spectrum of subjects physiology of sensory perception, psychology of human behaviour, flavour chemistry, physics of emulsion break-up and flavour release, testing methodology, consumer research, statistical data analysis. Not all of these aspects are of direct interest for the chemometrician. In this chapter we will cover a few topics in the analysis of sensory data. General introductory books are e.g. Refs. [1-3]. 

This problem is overcome by the Bio View sensor, which offers the possibility to monitor the whole spectral range simultaneously, and by using suitable data analysis and mathematical methods like chemometric regression models 11061. Real-time fluorescence measurement can be used more effectively comparing time-consuming off-line methods. Partial least squares (PLS) calibration models were developed for simultaneous on-line prediction of the cell dry mass concentration (Fig. 5), product concentration (Fig. 6), and metabolite concentrations (e. g., acetic acid, not shown) from 2D spectra. 

As the preceding example suggests, considerable information can be obtained by sophisticated data analyses. Often proper data analysis takes more time than data acquisition and it is easy to take more data than can be reasonably analyzed. A distinction should be made concerning controlled or semi-controlled measurements and exploratory searching. Frequently, the presence or absence of a particular element provides all the necessary information and analysis is simple and immediate. However, further quantification of such an analysis can be difficult and time consuming. 

Minimal sample preparation (dilution in HPLC mobile phase) is necessary. A standard reversed-phase HPLC method is used for all the samples associated with a drug candidate to reduce time-consuming method development/method refinement procedures. Standard reversed-phase methods typically involve a 20-30 min cycle time and provide information on a wide range of compounds. The incorporation of a standard method strategy allows the use of autosampling procedures and standard system software for data analysis. 

EXAFS spectra can, in principle, be well described on the basis of scattering theory (although data analysis is time-consuming and demand considerable expertise). XANES spectra can only be predicted on the basis of first-principle calculations. As noted above, this is generally not necessary because in practice XANES data are interpreted with the help of reference spectra. 

Instrument automation may be required to provide us with more powerful techniques of data analysis and data handling using statistical techniques that would be otherwise too time consuming to be practical or computer graphics to gain greater flexibility in data analysis. Small data base systems of spectral libraries can help address a problem of faster component identification. 

A batch record, as stored in the database, is represented by a collection of different data on the actual production procedure and the current production enviromnent. Back in 1994, at the point of decision, the data available electronically were stored in several databases. Database update was time-consuming and difficult data analysis even needed different program interfaces. Therefore, the database for the new system had to be a central, uniform database for the whole production plant.The bill of material is fed from ERP as well as general planning. LIMS is another interface for the input of analytical data that is important in the calculation of correction factors for the content of API. 

If a consumer can gain access or become exposed to hazardous product characteristics, the probability of this event must be determined. Probable exposure to the hazard may be determined using injury and fatality data analysis.
