U.S.-Chile Program: Short-Term Visit to Plan Research on Control of Microbial DNA in Produce by UV Pulsed Radiation

9530894拉古纳斯-太阳能美洲项目奖将支持加州大学戴维斯分校曼努埃尔·拉古纳斯-索拉尔博士短期访问的旅费和相关费用，以开发一个与智利奇兰康塞普西翁大学胡安·A·卡努米尔·韦斯博士合作的研究项目。他们计划研究高功率单色紫外线(UV)辐射对控制新鲜农产品中微生物DNA的影响。该项目的主要目标是研究新鲜食品表面诱导的基本光化学，确定处理产品在各种物理、化学和生理条件下的处理效果，并评估新工艺在新鲜蔬菜中的应用。过去50年来，用于帮助保存食物的化学技术一直受到批评，因为它们增加了健康风险，以及它们对环境、我们的食物和我们的水留下的残留物。研究人员建议通过使用非添加的物理技术来减少对用于这些目的的化学品的依赖。***

9530894 Lagunas-Solar This Americas Program award will support travel and related expenses for a short-term visit by Dr. Manuel Lagunas-Solar, University of California, Davis, to develop a collaborative research project with Dr. Juan A. Canumir Veas, University of Concepcion, Chillan, Chile. They plan to investigate the effect of high-power monochromatic ultra violet (UV) radiation to control microbial DNA in fresh produce. The main objectives of the project are to study the basic photochemistry induced on the surface of fresh foods, determine the effectiveness of the treatment under a variety of physical, chemical and physiological conditions of the treated products, and to evaluate the application of the new process to fresh vegetables. The chemically-based technologies in use for the past fifty years to aid in the preservation of food have been subject to criticism because of the increased health risks, and the residues they leave on the environment, our food and our water. The researchers propose to decrease dependence on chemicals for these purposes throughout the use of non- additive physical technologies. ***
