9817050 Jackson The objective of this research is to minimize waste, waste generation and fresh water use in the corn nixtamalization process used in the manufacture of corn products such as corn chips, tortilla chips, tacos and corn tortillas. The traditional process involves cooking and steeping of corn in excess water and results in significant loss of corn solids and generation of large volumes of alkaline, high organic wastes. The objective of this project is to minimize waste generation and fresh water use by optimizing the principal variables, process modeling and developing novel process approaches. The research will be conducted following two paths. The first approach will be to optimize the traditional nixtamalization process, minimizing water use and waste generation, using Response Surface Methodology and process modeling to optimize the process variables. The second approach will be to develop a novel enzymatic processing technique that uses steam to cook the corn without alkali and pericarp degrading cellulolytic enzymes to digest the cooked corn to reduce water intensity and corn loss. This award is made by NSF as part of the joint NSF/EPA Program on Technologies for a Sustainable Environment.***

9817050杰克逊本研究的目的是使在玉米产品如玉米片、玉米饼片、玉米饼和玉米饼的生产中使用的玉米蒸煮过程中的废物、废物产生和淡水使用最小化。 传统的方法包括在过量的水中蒸煮和浸泡玉米，导致玉米固体的显著损失和产生大量碱性高有机废物。 该项目的目标是通过优化主要变量、工艺建模和开发新的工艺方法来最大限度地减少废物产生和淡水使用。 研究将沿着两条路径进行。 第一种方法将是优化传统的碱法处理工艺，最大限度地减少水的使用和废物的产生，使用响应面方法和工艺建模来优化工艺变量。 第二种方法将是开发一种新的酶处理技术，该技术使用蒸汽来煮玉米，而不使用碱和果皮降解纤维素分解酶来消化煮过的玉米，以减少水强度和玉米损失。 该奖项由NSF颁发，是NSF/EPA可持续环境技术联合计划的一部分。
