The polysaccharide structure-forming agent carrageenan has found wide application in food production. One of its advantages is an ability to show synergism with different hydrocolloids - xanthan gum, guar gum, locust bean gum and others. The possibility of the combined use of carrageenan and konjac gum to produce strong stable gels was studied in this work. The objects of the research were 1% gels of refined kappa-carrageenan (E407) and konjac gum (E 425 (i)) in different concentrations with the following ratios of carrageenan and konjac gum: control - 1 : 0; No.1–7 : 1; No.2–3 : 1; No.3–5 : 3; No.4–1 : 1; No.5–3 : 5; No.6–1 : 3; No.7–1 : 7; No.8–0 : 1. A quantity of syneretic moisture was determined in the prepared gels during cold storage for 14 days; gel hardness and springiness were determined using a universal testing machine Shimadzu AGS-1kN series (Japan). It was found that introduction of konjac gum in an amount of up to 0.625 % into the composition of the kappa-carrageenan gel facilitated an increase in gel hardness and elasticity with the exponential dependency. The following increase in the gum dosage led to a reduction of gel hardness and springiness. The use of konjac gum did not have a significant effect on carrageenan syneresis. It was established that the optimal ratio of carrageenan and konjac gum for producing strong and plastic gels was 1:1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
