je nutritivno vredna i koja svojim funkcionalnim svojstvima obezbeđuje pozitivan
uticaj na zdravlje ljudi. Senf nije samo začin kojim se obogaćuju ukus i miris mnogim
jelima, već je namirnica koja umnogome poboljšava metabolički sistem organizma i koja
svojim komponentama doprinosi prevenciji nekih bolesti.
U okviru ove doktorske disertacije optimizovan je tehnološki postupak proizvodnje
četiri vrste senfa sa aspekta stvaranja aromatskog kompleksa. Proizvedeni su blagi senf,
senf sa začinskim biljem, senf za roštilj i senf sa čilijem. Pre početka proizvodnje urađena
su mikrobiološka ispitivanja sirovina koje ulaze u sastav receptura i kontrola kvaliteta
suncokretovog ulja koje je komponenta u proizvodnji senfa. Svaki od ova četiri uzorka je
dobijen nakon ispitivanja niza probnih receptura, korigovanjem ukusa, mirisa, boje i
konzistencije uz senzorno ocenjivanje stručnog tima degustatora. Najbolji uzorci su
senzorno ocenjivani i u odnosu na iste vrste senfa koji se mogu naći na domaćem ...tržištu.
Senzorno ocenjivanje je obavljeno na osnovu deskriptivnog analitičkog bod sistema.
Rezultati su statistički obrađeni.
Na svim uzorcima su urađena fizičko-hemijska, mikrobiološka ispitivanja, kao i fizičkohemijska
ispitivanja kontaminanata (sadržaj ostataka pesticida, teških metala i mikotoksina)
i određena je energetska vrednost uzorka.
Svi rezultati su pokazali da su uzorci četiri vrste senfa u skladu sa Pravilnikom o
kvalitetu i drugim zahtevima za senf, Pravilnikom o kvalitetu i uslovima upotrebe aditiva u
namirnicama i o drugim zahtevima za aditive i njihove mešavine, Pravilnikom o
mikrobiološkoj ispravnosti namirnica u prometu i Pravilnikom o količinama pesticida,
metala i metaloida i drugih otrovnih supstancija, hemioterapeutika, anabolika i drugih
supstancija koje se mogu nalaziti u namirnicama.
Eksperiment je imao za cilj da se izvrši analiza degradacionih produkata sinalbina u
proizvedenom blagom senfu. Uzorci su ekstrahovani u Soxhlet-ovom sistemu, a potom
analizirani metodama gasne hromatografije-masene spektrometrije. Rezultati su poređeni sa
rezultatima mlevenog semena bele slačice koje je korišćeno u procesu proizvodnje senfa.
Ovi rezultati ukazuju na to da su dominantne masne kiseline, prvobitno prisutne u semenu
bele slačice takođe prisutne i u gotovom proizvodu, blagom senfu. Najobilniji degradacioni
proizvod sinalbina u senfu bio je 4-(hidroksimetil)fenol. Druga identifikovana jedinjenja u senfu bila su: 4-metil fenol, 4-etil fenol, 4-(2-hidroksietil)fenol i 2-(4-hidroksifenil) etanska
kiseline...
nutritionally valuable and that their functional properties provide a positive effects on
human health. Mustard is not just a spice that enriches the taste and smell to many foods,
but it is also the foodstuff that greatly improves the metabolic system of a human body and
its components contribute to the prevention of some diseases.
Within this Ph.D. Dissertation a technological process of production of four kinds of
mustard is optimized from the aspect of the aromatic complex formation. Mild mustard
paste, mustard paste with herbs, barbecue mustard paste and chili mustard paste were
produced. Before the start of production microbiological analyses were done on the raw
materials. Quality control of the sunflower oil, which is a component in mustard paste, was
analyzed as well. Each of the four samples was obtained after a detailed examination of
series of test recipes, adjustment of the taste, aroma, color and consistency with the sensory
evaluation team of professional tasters. The be...st samples were sensory evaluated and
compared to the same type of mustard that can be found in the domestic market. Sensory
evaluation was conducted with the descriptive analytical method, system of scoring. The
results were statistically analyzed.
All samples were analyzed by physico-chemical analyses, microbiological analyses,
physical-chemical analyses of contaminants (the contents of pesticide residues, heavy
metals and mycotoxins) and energy value of the sample.
All results showed that the samples of four kinds of mustard were in accordance with
the Regulation on quality and other requirements for mustard, Regulation on the quality
and conditions of usage of additives in food and the other requirements for additives and
their mixtures, Regulation on microbiological food safety in the market and Regulation on
the amount of pesticides, metals and metalloids and other toxic substances,
chemotherapeutics, anabolics and other substances which can be found in food.
The purpose of the experiment was investigation of sinalbin degradation products in
produced mild yellow mustard paste. The samples were extracted in a Soxhlet extraction
system and analyzed by gas chromatography - mass spectrometry (GC-MS) techniques.
The results were compared with the analysis of the ground white mustard seeds which were dominant fatty acids, originally present in the white mustard seeds, are also present in the
mustard paste condiment made from this plant. The most abundant sinalbin degradation
product in yellow mustard paste was 4-(hydroxymethyl)phenol. Other compounds identified in this sample were: 4-methyl phenol, 4-ethyl phenol, 4-(2-hydroxyethyl)phenol
and 2-(4-hydroxyphenyl) ethanoic acid...
