PROBLEM TO BE SOLVED: To provide a syneresis reducing agent for jam, having syneresis reduction effect while excellently retaining the flavor and texture of a food.SOLUTION: A syneresis reducing agent for jam includes water-soluble polysaccharide containing galacturonic acid derived from beans, and has a viscosity of 10 wt.% of the aqueous solution of the water-soluble polysaccharide of 150 mPa s or lower at 20°C. The syneresis reducing agent for jam has a methyl esterification degree of the water-soluble polysaccharide containing galacturonic acid derived from beans of 50% or less. In the syneresis reducing agent for jam, syneresis reduction effect is decreased by 15% or more to a syneresis amount when not adding the syneresis reducing agent. Jam containing the syneresis reducing agent for jam is also provided.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】食品の風味、食感を良好に保ちつつ、離水低減効果があるジャム類用離水低減剤の提供。【解決手段】豆類由来のガラクツロン酸を含有する水溶性多糖類を含み、該水溶性多糖類の10重量%水溶液の粘度が20℃で150mPa・s以下である、ジャム類用離水低減剤。豆類由来のガラクツロン酸を含有する水溶性多糖類のメチルエステル化度が50%以下であるジャム類用離水低減剤。離水低減効果が、離水低減剤の無添加時の離水量に対して15%以上低減するものであるジャム類用離水低減剤。前記ジャム類用離水低減剤を含有するジャム類。【選択図】なし
