This study analyzes the certification system and international standard trend for cold storage and proposes evaluation method for the development of KS in accordance with international standards so that high quality products can be supplied to consumers. The international standard for cold storage can be divided into three categories: refrigerator unit, refrigerator warehouse, and cold chain. Each similar standard was analyzed and studied. Among them, AHRI's international standard is the most advanced standard, so test methods and conditions are matched. Finally, the performance evaluation technology and the performance evaluation technology for the refrigerator unit suitable for the domestic situation using the analyzed method were proposed.

We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea,using the following 5 inspections items: “putting into warehouse (A)”, “prevention of cross-contamination (B)”, “storage management (C)”, “temperature control (D)”, and “management of records and documents (E)”, We included 20detailed items. The results of distribution for frequency by five major inspection items showed that “(E)” was the highest,the next “(D)”, “(C)”; and “(B)” was the lowest. In the correlation of inspection scores between total scores, “(B)”and “(C)” were highly related to the total score, therefore, the higher score of “(B)” or “(C)”, the higher for the total score. In details of inspection items, “the management of cross-contamination upon taking product out of the warehouse”had the lowest score with a mean, of 2.67 ± 1.80, and also ranked as first of the 20 items.
