One of the solutions to increase children's energy intake is the use of amylase-rich flours. This led us to optimize the fluidification capacity of two paddy rice varieties. For that, the Doehlert plane-type response surface methodology was used to optimize the germinating ability of paddy rice flour (varieties and ) to fluidize cassava-based gruels by using two factors: soaking and germination time. The evaluated response was the flow velocity of the gruels. The optimization result showed that, the optimal soaking time was 48 h for the variety and 12 h for . Concerning the optimal germination time, it was 135 h for both varieties. These conditions have been found to have the best fluidifying capacities for cassava flour-based gruels. The incorporation of 3 g germinated paddy rice flour ( and ) and at optimal conditions, allowed us to obtain high flow velocities of the gruels. They were 100.00 mm/30 s and 210.66 mm/30 s respectively for the varieties and . These flow velocities were similar to the flow velocities predicted by the model for desirabilities of 0.99 and 1.00. In view of all these results, we could therefore recommend the use of these two varieties of rice produced under these conditions to improving flow velocities, dry matter concentrations and energy bulk of the gruels.
增加儿童能量摄入的解决方案之一是使用富含淀粉酶的面粉。这促使我们优化两个水稻品种的流化能力。为此，采用Doehlert平面型响应面方法，通过浸泡时间和发芽时间这两个因素，优化水稻粉（品种 和 ）使木薯糊流化的发芽能力。评估的响应指标是糊的流速。优化结果表明，品种 的最佳浸泡时间为48小时，品种 的最佳浸泡时间为12小时。关于最佳发芽时间，两个品种均为135小时。已发现这些条件对木薯粉糊具有最佳流化能力。在最佳条件下加入3克发芽水稻粉（品种 和 ），使我们能够获得较高的糊流速。品种 和 的糊流速分别为100.00毫米/30秒和210.66毫米/30秒。这些流速与期望度为0.99和1.00时模型预测的流速相似。鉴于所有这些结果，因此我们可以推荐使用在这些条件下生产的这两个水稻品种，以提高糊的流速、干物质浓度和能量含量。
