ABSTRACT

There is increasing demand to use the microorganisms, supporting consumer health and stimulating immune system, in food production. The role of probiotics which are one of the most important group of this microorganisms on the preventation of gastrointestinal diseases and treatment and development of normal gastrointestinal flora were determinated by clinical trials. On the other hand, studies on the strain-dependent food preservation effects and the potentials for treatment of different diseases of probiotics are ongoing. Probiotic preparats that have effective potential especially for the treatment acute diarrhea in children and antibiotic associated diarrhea have been developed. In this review, newsworthy information on the criteria for probiotic strain selection, curing potentials and their application possibilities were presented.

Keywords : Probiotics, Gastrointestinal system, Food safety, Treatment.

E. Glossary of selected terms
Amplified Fragment Length Polymorphism (AFLP): Amplified fragment length polymorphism is a novel molecular fingerprinting technique that can be applied to DNAs of any source or complexity. Total genomic DNA is digested using two restriction enzymes. Double-stranded nucleotide adapters are ligated to the DNA fragments to serve as primer binding sites for PCR amplification. Primers complementary to the adapter and restriction site sequence, with additional nucleotides at the 3’-end, are used as selective agents to amplify a subset of ligated fragments. Polymorphisms are identified by the presence or absence of DNA fragments following analysis on polyacrylamide gels. This technique has been extensively used with plant DNA for the development of high-resolution genetic maps and for the positional cloning of genes of interest. However, its application is rapidly expanding in bacteria and higher eukaryotes for determining genetic relationships and for epidemiological typing.
Biosensor: is the self-contained analytical device that responds selectively and reversibly to the concentration or activity of chemical species in biological samples using various types of sensors of biological nature. Any sensor physically or chemically operated in biological samples can be considered as biosensor.
Classical mutagenesis: The process involves the production of mutants through the exposure of microbial strains to mutagenic chemicals or ultraviolet rays to induce changes in their genomes. Improved strains thus produced are selected on the basis of specific properties such as improved flavour-producing ability or resistance to bacterial viruses.
Conjugation: This is a natural process whereby genetic material is transferred among closely related microbial species as a result of physical contact between the donor and the recipient micro-organisms.
Enzyme-Linked Immunosorbent Assay (ELISA): An immunoassay that uses specific antibodies to detect antigens or antibodies in body fluids. The antibody-containing complexes are visualized through enzymes coupled to the antibody. Addition of substrate to the enzyme-antibody-antigen complex results in a coloured product.
Genomics: is the study of genes and their functions, and related technologies.
Hybridization: This is the common sexual breeding or mating process leading to genetic recombination. Such sexual crossing has led to offspring with superior or improved qualities. For example, the crossing of haploid yeast strains with excellent gassing properties and good drying properties could yield a novel strain with both good gassing and drying properties.
Polymerase Chain Reaction (PCR): is a method to amplify DNA in vitro, involving the use of oligonucleotide primers complementary to and annealing at different positions of nucleotide sequence in a target gene. The copying of target sequences is by the action of DNA polymerase.
Probe: is a single-stranded nucleic acid that has been radio-labelled, and is used to identify a complementary nucleic acid sequence that is membrane-bound.
Randomly Amplified Polymorphic DNA (RAPD): Randomly amplified polymorphic DNA and arbitrarily primed PCR (AP-PCR) represent novel DNA polymorphism assays, sometimes referred to as DNA fingerprinting, that involve the amplification of random DNA segments using PCR and oligonucleotide primers of arbitrary sequence. Products defining the polymorphisms exhibit Mendelian inheritance, and thus possess tremendous potential utility as genetic markers in a diverse array of scientific disciplines.
Recombinant DNA Technology: This technology is the application of in vitro nucleic acid techniques including recombinant deoxyribonucleic acid (DNA) and direct injection of nucleic acids into cells and organelles (adapted from Codex CAD/GL 44-2003, CAD/GL 45-2003, CAD/GL 45- 2003 and CAD/GL 68-2008)

SUMMARY  

The  foundation  of  this  study  is  based  on  the  HACCP  organization  in  yoghurt   production. In this study, HACCP system was set up in the yoghurt production line of a dairy   plant which has a daily capacity of 80 – 100 tonnes of milk. The logic sequence for application of HACCP which had been developed basing on 7   basic principles (Unlütürk and Turantas,1998; Karaali, 2003; Anonymous, 2005) was used as   a method in this study. In the development of the company’s HACCP plan, generic HACCP   models of Canadian Food Inspection Agency (CFIA) were been utilized. Initially  a  team  consisting  of  five  persons  three  of  whom  are  employed  in  different   positions of the company and who had sufficient knowledge and expertise to be able to carry   out the plan in question were assembled. The definition of the product was made by the team,   and important product characteristics those effect on the process (pH, minimum fat and SNF   percentages etc.) were determined and after  the product ingredients and raw materials have   been listed a process flow diagram was prepared. The hazards that could arise from the raw  material of the product to the end product   were researched and they were been evaluated by the assembled HACCP team. Each potential   hazard  that  have  been  put  forward  from  raw  material  (raw  milk)  to  the  distribution  of  the   product was been applied to the critical control point decision tree. 6 different critical control   points  was  determined  and  the  process  stages  in  question  were  been  classified  as  follows: 1)   Raw   material   (Raw   milk   &   Milk   powder);   2)   Raw   milk   cooling   and   storage; 3) Pastorization; 4) Purchase  and addition of starter cultures; 5) Packaging; 6) Incubation /   Cooling                In order to enhance the reliability of the HACCP study, it was paid attention to keep   the critical control points at the minimum level. The safety of the control points other than the   critical   control   points   were   assured   by   the   prerequisite   programs   such   as   purchase   spesifications, standard operation procedures, GMP (Good Manufacturing Practices) and GHP   (Good Hygiene Practices). 2007, 67 pages

Establishment of the HACCP Plan in a Catering Plant

In this study, HACCP (Hazard Analysis Critical Control Point) plan was set up in a catering plant which   had a  capacity of 2000 persons/day and 40 employees. Founded HACCP system consisted of the following   seven principles: (1) Conducting a hazard analysis, (2) determining the Critical Control Points (CCPs), (3)   establishing  critical  limit(s),  (4)  establishing  a  system  to  monitor  control  of  the  CCP,  (5)  establishing  the   corrective  action  to  be  taken  when  monitoring  indicates  that  a  particular  CCP  is  not  under  control,  (6)   establishing   the   procedures  for   verification   that   the   HACCP   system   is   working   effectively   and   (7)   documentation of all procedures and records appropriate to these principles and their application.         That  action  was  carried  out  by  following  this  diagram:  (1)  Assembling  HACCP  team,  (2)  describing   terms   and   intention,   (3)   describe   product,   (4)   identifying   intended   use   and   consumer   category,   (5)   constructing the flow diagram, (6) on-site confirmation of flow diagram, (7) listing all potential hazards and   considering control measures, (8) determining CCPs,  (9) establishing a monitoring system and critical limits   for  each  CCP,  (10)  establishing  the  corrective  actions,  (11)  keeping  record  procedure,  (12)  establishing   verification procedures and, (13) revision of HACCP implementation.
