The present invention high shape retention even when it is extruded from a syringe or the like, and providing a semi-solidified nutritional supplement and method for adjusting the resistance is small when extruding the tube. A nutrient, a gastrostoma half solidified nutritional supplement, including jelly strength 10kPa following agar, and modified starch, wherein the gastrostoma half solidified the content of the jelly strength following 10kPa agar is a 0.05% by weight based on the total amount of nutrients, the content of the modified starch is based on the total amount of the gastrostoma semi solidified nutritional supplement, a 0.1-7 wt%, stomach semi-solidified nutritional supplement.【課題】シリンジ等から押し出した場合にも保形性が高く、かつチューブから押しだす際の抵抗が少ない半固形化栄養剤及びその調整方法を提供すること。【解決手段】栄養素、ゼリー強度が10kPa以下の寒天、および加工デンプンを含む胃瘻用半固形化栄養剤であって、前記ゼリー強度が10kPa以下の寒天の含有量が前記胃瘻用半固形化栄養剤の全量に対して0.05~1質量%であり、前記加工デンプンの含有量が前記胃瘻用半固形化栄養剤の全量に対して、0.1~7質量%である、胃瘻用半固形化栄養剤。
