Properties of cereal β-D-glucan hydrocolloids and their effect on bread and ketchup parameters

Abstract

Microbiological and sensory evaluations of bread and ketchup supplemented with β-D-glucan hydrogels isolated from wheat, oat, barley, and rye were carried out. Adding hydrocolloids did not affect sensory parameters of bread negatively; moreover rye and oat β-D-glucans improved the total tastiness of bread. Water activity values in fortifi ed breads showed β-D-glucans, except isolated from oat, as elements moderately increasing this parameter and subsequently increasing also bread freshness during the storage. All β-D-glucans resulted in softening the acidic taste of ketchup and did not negatively infl uence the total tastiness. Quality of fortified fresh tomato ketchups and stored for 180 days, were also not negatively infl uenced by the addition of hydrocolloids. Therefore, cereal hydrocolloids could be very perspective in the further exploitation in preparing new health-benefi cial foods. © Copyright by Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences.
