Abstract

Mikrobiološko istraživanje proizvoda i poluproizvoda koji ulazi u sastav gotovog proizvoda, važno je kako bi se potvrdila i dokazala zdravstvena ispravnost. Da bi se ostvarila sigurnost i kakvoća proizvoda potrebno je pridržavati se propisane zakonske regulative, te provoditi dobru laboratorijsku praksu. Istraživanja u ovom radu temeljila su se na mikrobiološkom istraživanju uzoraka gazirane prirodne mineralne vode, izotoničnog negaziranog napitka, te sirupa negaziranog izotoničnog napitka kroz nekoliko faza proizvodnog procesa. Proizvodi su istraživani u skladu s internim zahtjevima tvrtke „Jamnica“ d.d. na prisutnost mikroorganizama i to: ukupan broj aerobnih mezofilnih bakterija, ukupan broj koliformnih bakterija, fekalne koliformne bakterije, Pseudomonas aeruginosa, fekalne streptokoke, kvasce i plijesni. Korištene su kvantitativne metode istraživanja, u skladu s ISO (Internationl Organization for Standardization) i internim metodama rada u skladu s trenutno važećom zakonskom regulativom. Rezultati istraživanja pokazali su da su sve dobivene vrijednosti unutar propisanih mikrobioloških internih zahtjeva, te se može zaključiti da su proizvodi pogodni za upotrebu.

Abstract (english)

Microbiological research of the products and semi-finished products that are stated as the ingredients of the finished products has an important role in confirming and authenticating the health safety. In order to obtain the necessary product safety and quality standard legal procedures should be observed, and good laboratory operation performed. The researches described in this paper were based on the microbiological examination of naturally carbonated water samples, of non carbonated isotonic drink, and of the non carbonated isotonic drink syrup, during the several phases of the production process. The products were examined in keeping with the internal requirements for the presence of microorganisms: the total number of aerobic mesophilic bacteria, the total number of coliform bacteria, fecal coliform bacteria, Pseudomonas aeruginosa, fecal streptococci, yeasts and molds. Implemented were the quantitative research methods, conforming to the ISO standards, as well as the internal methods that comply with the presently applicable legislation. The results showed that all the values of the research were within the internal microbiological requirements, leading to the conclusion that the products are in condition to be used.
