Studies on the preparation methods for rice gruel made from cooked rice adaptable for the person in difficult to mastication and swallowing

1.研究了原料大米中不同水分配比的影响。糙米中加入的水的比例分别为1.3、1.5、1.7，将这些不同水与糙米的煮熟的大米制成的米粥分别称为×1.3、×1.5和×1.7。×1.7米粥的硬度和断裂应力水平较低，外观明显易碎。×1.3和×1.5米粥的硬度、断裂应力和黏度均高于×1.7米粥，其外观与生米米粥相似。煮20分钟的米粥与生米粥的感官评价相似。研究了真空包装蒸煮方法。采用真空包装的方法，将煮熟的大米制成米粥，在沸水中煮20分钟。它比生米的短。研究了不同冷冻温度和不同冷冻形态下粥样的性质。冷冻温度为-20℃或-40℃，形态为片状或聚集状，重量为100 g或200 g。-40℃、片状和100 g组合时，最大冰晶形成温度区通过的时间比-20℃、凝聚和200 g组合时要短。在-40℃、薄片、重量为100 g保存时，其硬度和粘附性均低于在-20℃、团聚性和重量为200 g保存时。以-40℃、薄板、重量为100 g的组合条件对粥样的评价高于其他组合。

1.The effect of the ratios of the water added to the raw rice was studied. The ratios of the water added to the raw rice were 1.3, 1.5, 1.7, and the rice gruels prepared from these cooked rice differing water to raw rice were respectively called ×1.3, ×1.5 and ×1.7. The rice gruel of ×1.7 showed a low level of hardness and rupture stress, and was distinctly crumbly in appearance. The rice gruels of ×1.3 and ×1.5 showed higher levels hardness and rupture stress and greater viscosity than the ×1.7 rice gruel, and had a similar appearance to that of rice gruel prepared from raw rice. The rice gruels that were cooked for 20 minutes had a similar sensory evaluation to gruel made from raw rice.2.The cooking method by vacuum packaging was studied. Using the vacuum packaging method, cooking time of the rice gruel prepared from cooked rice was 20 minutes in boiling water. It was shorten than that from raw rice.3.The properties of gruel samples preserved at different freezing temperatures and forms were studied. The freezing temperature was -20℃ or -40℃, and the form was a sheet or aggregation, and the weight was 100 g or 200 g. The time for the passing of the zone of maximum ice crystal formation temperature was shorter in the combination of -40℃, sheet and 100 g than the combination of -20℃, aggregation, and 200 g. Preservation at -40℃, sheet, and weight of 100 g showed less hardness and adhesiveness than in -20℃, aggregation and weight of 200 g. The gruel sample combining condition of -40℃, sheet, and weight of 100 g had higher evaluation than other combinations.
