Senzorski, nutritivni i funkcionalni profil integralne testenine sa dodatkom heljdinog brašna / Sensory, nutritional and functional profile of whole grain pasta with buckwheat flour addition

<p>U okviru disertacije ispitani su i upoređeni pokazatelji kvaliteta integralnog p&scaron;eničnog i integralnog heljdinog bra&scaron;na dobijenog mlevenjem netretiranih (netretirano integralno heljdino bra&scaron;no) i autoklaviranih zrna heljde (autoklavirano integralno heljdino bra&scaron;no). Nakon ispitivanja nutritivnih i funkcionalnih svojstava pomenutih bra&scaron;na, kreirane su i proizvedene integralne taljatele sa različitim sadržajem integralnog heljdinog bra&scaron;na (10&ndash;30%).<br />Pokazatelji senzorskog, nutritivnog i funkcionalnog kvaliteta proizvedenih taljatela sa integralnim heljdinim bra&scaron;nima ispitani su u poređenju sa kontrolnim uzorkom taljatela od integralnog p&scaron;eničnog bra&scaron;na.<br />U ispitivanim uzorcima bra&scaron;na i taljatela određeni su osnovni hemijski sastav, sadržaj mineralnih materija, sadržaj ukupnih rastvorljivih polifenola, utvrđen je kvalitativni i kvantitativni sastav polifenolnih jedinjenja, ispitana je antiradikalska aktivnost na DPPH˙ i određen je sadržaj fitinske kiseline i 5-hidroksimetilfurfural.<br />Pored analize nutritivnih i funkcionalnih svojstava, na taljatelama su sprovedena ispitivanja fizičkih osobina (dimenzije) i svojstva taljatela pri kuvanju. Instrumentalno su izmereni boja i teksturna svojstva nekuvanih i kuvanih taljatela. Senzorska ocena taljatela sprovedena je uz primenu panela utreniranih ocenjivača, metodom bodovanja i panela potro&scaron;ača, testom dopadljivosti.<br />Dobijeni rezultati ukazuju da se supstitucijom dela integralnog p&scaron;eničnog bra&scaron;na integralnim heljdinim bra&scaron;nom (autoklaviranim ili netretiranim) postiže unapređenje nutritivnog i funkcionalnog profila uzoraka obogaćenih taljatela, uz manje ili vi&scaron;e izraženo naru&scaron;avanje senzorskog profila, u zavisnosti od stepena supstitucije i vrste integralnog heljdinog bra&scaron;na.</p> / <p>This study investigated quality parameters of wholegrain wheat flour and wholegrain buckwheat flour from non-treated buckwheat grains (non-treated wholegrain buckwheat flour) and autoclaved buckwheat grains (autoclaved wholegrain buckwheat flour). After investigation of nutritional and functional properties of aforementioned flours, new wholegrain tagliatelle formulations, with different wholegrain buckwheat flour content (10&ndash;30%) have been developed.<br />Sensory, nutritional and functional quality parameters of buckwheat containing tagliatelle samples were analysed and compared with control tagliatelle sample from wholegrain wheat flour.<br />Proximate composition, content of minerals, content of total polyphenols and quantitative and qualitative composition of polyphenols were investigated in both, flour samples and produced uncooked and cooked tagliatelle samples. Antiradical activity on DPPH radicals, and content of less favourable compounds, phytic acid and HMF, have been tested, as well.<br />Tagliatelle physical properties, dimensions, cooking properties, colour and textural properties were determined by instrumental and sensory methods. Tagliatelle acceptability was evaluated by the consumers. The obtained results indicate that wholegrain buckwheat flour (autoclaved or non-treated) incorporation into tagliatelle formulation led to an improvement of nutritional and functional profiles of tagliatelle samples, followed by greater or lesser deterioaration of sensory profile, depending on substitution level and type of wholegrain buckwheat flour.</p>
