Barley is considered as one of the most important cereals for Korean in terms of production and utilization. In this review we concentrate mainly on the chemical structure of husk, aleurone layer, endosperm and embryo (especially endosperm). The relationships among the structure, characteristics and role of chemical components in barley kernel are also discussed. The nature of the fine-structure and minor components is not fully identified, however, a lot of investigation and progress in this area probably contributes the development of new technique for better utilization of barley in the future.

This study was carried out to understand the contamination patterns of Listeria in pork processing plants. A total of 402 samples were collected from carcass, pork during processing, surfaces of equipment and environment, and 238 isolates of Listeria species were identified. L. innocua was found in 64.7% of the isolates, L. monocytogenes in 33.2%, and L. welshimeri in 2.1%. Random amplified polymorphic DNA (RAPD) analysis performed to investigate the origin and routes of Listeria contamination, showed 21 composite types of L. monocytogenes and 26 composite types of L. innocua. It was confirmed that Listeria contamination begins with contaminated incoming carcass and ever-present contaminants in the processing environments. The persistence and dissemination of the same strain of L. monocytogenes and L. innocua throughout the processing line revealed that the sanitation standard operating procedure should be implemented to minimize the risk of colonization in the workplace. Molecular subtyping of L. innocua allowed us to tracing the possibility of cross-contamination during processing.
