Provided is a highly thickening composition which overcomes drawbacks seen in thickening compositions using a polysaccharide in that a desired viscosity cannot be achieved when the thickening composition is added to a liquid composition having a specific salt concentration, and that even when the desired viscosity is achieved, the resultant liquid composition shows deterioration of texture such as remaining in the mouth or being hard to swallow because the resultant liquid composition undergoes little change in viscosity at respective temperatures, and which has a synergistically excellent thickening property. A highly thickening composition produced by mixing one of either (A) xanthan gum or (B) locust bean gum with (C) guar gum and then mixing the component (A) or the component (B) to the resultant mixture, wherein the ratio of the total amount of the components (A) and (B) to the amount of the component (C) is 95:5 to 70:30 by mass and the component (A) is contained in a larger amount than the component (B).提供一種高增黏性糊料組成物，其針對使用有多糖類之增黏性糊料組成物克服如下缺點而協同地顯示優異之增黏性：若含有於具有特定食鹽濃度之液狀組成物中，則無法獲得所欲黏度，又，於獲得所欲黏度之情形時，所獲得之液狀組成物於各溫度區域中之黏度變化較少，因此用於食品時產生殘留於口中或難以吞嚥等食感降低。製成一種高增黏性糊料組成物，其係含有(A)三仙膠、(B)刺槐豆膠及(C)瓜爾膠之糊料組成物，(A)成分與(B)成分之合計量與(C)成分之比以質量比計為95：5~70：30，且使(A)成分之含量多於(B)成分之含量。
