Документ Research on technological properties of potato cellulose for bread production(2016) Silchuk, Tatiana; Nazar, Mariana; Holikova, TatianaThe problem of deficiency of food fibers in food rations leads to the necessity of searching new sources of ballast compounds. One of the perspective ways of solving this problem is the use of potato cellulose to fortify by food fibers daily used products such as bread and bakery products. Potato cellulose is a high dispersive and contains a high amount of food fibers. Water absorption of potato cellulose has been investigated as well as its effect on the quality of dough and bread. Potato cellulose has water absorption between 1.5 … 2 times higher than in wheat bran thus giving the possibility of making ready products of proper quality. The effect of food cellulose addition to the gluten content in dough has been presented. The expediency of potato cellulose used to enrich ready bread products has been proven.Документ Study of the mechanism of the retarding effect by using natural gums(2013) Palyvoda, Svetlana; Yurchak, Vera; Holikova, Tatiana; Fomenko, VenіamіnThe mechanism of natural gums' effect on the preservation of bread freshness has been studied. The stage of bread staleness was estimated from the deformation of bread’s crumb. Hydrophilicity and texture of bread crumb were also considered. The mechanism of gum’s effect on the process of bread staling was studied by determining the respective change in the state of flour starch crystal structure, which was assessed by qualitative Roentgen phase analysis and the change of bread matter moisture bonds with the addition of gums, which was determined by the method of differential thermal analysis. As the result of the research, it was found that addition of natural gums accommodates bread shelf-life extension by means of crumb texture change, as well as the effect on bread biopolymer moisture bonds
