 Buletinul USAMV-CN, 62/2006  ISSN 1454-2382  RESEARCH OF FOOD PRODUCT QUALITY USING A  NONQUALITY DETERMINATION METHOD  Pîrvulescu LuminiŃa, Claudia Sîrbulescu, Carmen Dumitrescu, Despina Bordean, Elena Volloncs Banat’s University of Agriculture Sciences and Veterinary Medicine Calea Aradului, 119, 300645, e-mail : pirvulescu_l@yahoo.com  Key words: quality, nonquality, food product, demerits method  SUMMARY  The same of properties that a product owns, as an expression of the level in which the needs of the society are fulfilled, taking into consideration the technique, economic and a esthetical parameters, the level of usage and economic efficiency in usage, are known with the usual term of quality. In the present paper is realised an analysis of wheat quality through determining the nonquality, using in this purpose the demerits method by penalizing the defects. The average demerit on controlled lot represents the sum of total demerits values on controlled product unit, divised to verified products number:  D = (100 · Nc + 50 · Np + 10 · Ns + Nm) 1/n, in which n – the number of controlled units; Nc, Np, Ns and Nm – the number of products presenting critical, principal, secundary, respectively minor defects. The data used in this paper are obtained from the S.C. PIRI S.L.R. from Timişoara, being obtained from the qualitative reception operations. The analyst divises the wheat properties in: critical (the contain and gluten forming index, wheat diseases); principal (hectolitrical weight, humidity); secundary  (glassyness, strange corps, grains dimension) and minor (form, grains colour). The study is realised on a six months period, begining in January and finishing in June (2005). The obtained results are presented in table 1 and figure 1.

The demerits method offers information regarding the products quality level at a specified time and this evolution in time.  2. Bigger the demerit value, lower the quality.   BIBLIOGRAPHY  1.
