Abstract
U ovom radu ispitivan je utjecaj karboksimetilceluloze (CMC) te biološkog i kemijskog zakiseljavanja na reološka svojstva suspenzije brašna (brašno T-550 i T-1100). Ispitivanja su provedena na amilografu i mikro visko-amilografu (Brabender), te na uređaju za određivanje broja padanja po Hagberg-Pertenu. Za kemijsko zakiseljavanje korištena je mliječna kiselina, a kao biološka sredstva zakiseljavanja korištena su svježe pripravljena kisela tijesta od dva soja mliječno-kiselih bakterija (Lactobacillus plantarum i Lactobacillus brevis) te kiselo tijesto u prahu. Rezultati su pokazali da korišteni dodaci značajno utječu na ispitivane reološke parametre suspenzije brašna. Dodatak CMC povisio je temperaturu početka bubrenja i temperaturu maksimuma kod svih ispitivanih uzoraka. Uzorci kojima su dodana kisela tijesta i mliječna kiselina imali su višu temperaturu početka bubrenja, a nižu temperaturu maksimuma. Svi ostali uzorci s dodatkom CMC imali su niže vrijednosti maksimalne viskoznosti na amilografu te više vrijednosti broja padanja i maksimalne viskoznosti određene na mikro visko-amilografu u odnosu na uzorke bez CMC.
Abstract (english)
Effects of carboxymethylcellulose (CMC) and biological as well as chemical acidification on flour suspension properties (flour T-550 and T-1100) were examined in this research. Amylograph and micro visco-amylograph were used after Brabender, and method for determination of falling number after Hagberg-Perten. Lactic acid was used for chemical acidification process whereas biological acidification involved freshly prepared sourdoughs from two strains of lactic-acid bacteria (Lactobacillus plantarum and Lactobacillus brevis) and dry sourdough. The examination results showed that additives being used significantly affected reological properties of flour suspension. Addition of CMC raised temperature when swelling started as well as temperature of the maximum of all examined samples. Samples with sourdough and lactic acid addition had higher temperature when swelling started, and lower temperature of the maximum. All other samples with CMC addition had lower maximum viscosity values when using amylograph, and higher falling number and maximal viscosity values using micro visco-amylograph compared to samples without CMC addition.
