It possesses the shift food impression of being closer to the meat, it designates that the satisfactory systematic condition plant protein material of the flavor whose at the same time bitterness and sourness are little is offered as purpose. The plant protein raw materials and sugar-alcohol are contained, content of sugar-alcohol in 0.1 dry weight weight % is above, it possesses the system which swells, at the same time possesses the absorption coefficient of 1 times or more, it possesses the shift food impression of being closer to the meat, it offers the satisfactory systematic condition plant protein material of the flavor whose at the same time bitterness and sourness are little. The said systematic condition protein material adding water doing in the raw materials which include the plant protein raw materials which add the sugar-alcohol of the specified quantity pushes out under pressurization heating, is produced by swelling.より畜肉に近い硬い食感を有し、かつ苦味や酸味の少ない風味の良好な組織状植物蛋白素材を提供することを目的とする。植物蛋白原料と糖アルコールを含有し、糖アルコールの含量が乾燥重量中0.1重量%以上であり、膨化された組織を有し、かつ1倍以上の吸水率を有する、より畜肉に近い硬い食感を有し、かつ苦味や酸味の少ない風味の良好な組織状植物蛋白素材を提供する。該組織状蛋白素材は、所定量の糖アルコールを添加した植物蛋白原料を含む原料に加水して加圧加熱下に押出し、膨化させることにより製造される。
