Abstract
Mlijeko je vrlo kvarljiva namirnica, stoga je kontrola kvalitete u pogledu higijenske ispravnosti i sastava iznimno bitna. Cilj istraživanja bio je utvrditi kemijski sastav i mikrobiološku ispravnost mlijeka prikupljenih iz 11 različitih mljekomata na području grada Zagreba i okolice, te ispitati odgovara li ona zakonski postavljenim kriterijima. Također je cilj bio utvrditi razlike u uzorcima sirovog mlijeka prikupljenim u dva različita godišnja doba. Uzorcima mlijeka određen je udio mliječne masti, proteina, laktoze, suhe tvari, bezmasne suhe tvari i pepela. Higijenska kvaliteta mlijeka određena je na temelju broja somatskih stanica i ukupnog broja mikroorganizama. Rezultati su pokazali da uzorci mlijeka kemijskim sastavom udovoljavaju odredbama Pravilnika o utvrđivanju sastava sirovog mlijeka (NN 27/17). Međutim, mikrobiološka analiza je dala zabrinjavajuće rezultate gdje niti jedan uzorak nije udovoljavao odredbama Zakona o higijeni hrane i mikrobiološkim kriterijima za hranu (NN 81/13). Prosječan broj somatskih stanica/mL u sirovom mlijeku na zadovoljavajućem je nivou i kod 77% uzoraka iznosi <400.000 BSS/mL.
Abstract (english)
Milk is a very perishable food so quality control of raw milk is very important in terms of protecting the health and safety of consumers. The aim of the research was to determine the chemical composition and microbiological validity of the milk collected from 11 different vending machines in the area of Zagreb, and to examine whether it complies with the legally set criteria. The aim was also to establish the differences in samples of raw milk collected in two different seasons. In the milk samples share of milk fat, protein, lactose, dry matter and ash were determined. Hygiene quality of milk was determined by the number of somatic cells and the total number of microorganisms. The results showed that chemical composition of raw milk from a vending machine samples matches the set of legal criteria. However, the microbiological analysis has given bad results where no sample was within legal criteria. The average number of somatic cells per mL in raw milk is at a satisfactory level and 77% of the milk samples were <400,000 BSS /mL.
