| Abstract | The growth of Listeria monocytogenes and Salmonella Typhimurium on fresh-cut cabbage at between 15 and 35°C before and after treatment with water washing, chlorine dipping, and chlorine dipping followed by water washing were investigated. It is apparent that these pathogens could grow faster at higher temperature. Chlorine treatments reduced L. monocytogenes and S. Typhimurium on cabbage by 1.04–1.15 log CFU/g and 1.35–1.51 log CFU/g, respectively. Gompertz model and polynomial equation were used to describe the behaviors of L. monocytogenes and S. Typhimurium on cabbage before and after treatment with water washing, chlorine dipping, and chlorine dipping followed by water washing as a function of temperature. The lag times of L. monocytogenes and S. Typhimurium were the longest when treated with chlorine dipping followed by water washing at 15°C. The growth rates of L. monocytogenes and S. Typhimurium were the lowest when treated with water washing at 15°C, indicating that the growth of pathogen was more affected by storage temperature than chlorine treatment. Validation was also performed to evaluate the reliability of developed predictive models. The Bf values of the growth rate and lag time for L. monocytogenes and S. Typhimurium ranged from 0.90 to 1.25, indicating that they were mostly in the acceptable level, whereas A$_{f}$ values ranged from 1.07 to 1.80, showing that they were over-predicted. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
