A Study on the Quality Evaluation of Imported Processed Foods(1)- With Special Reference to Chinese Products-

수입식품의 품질조사연구원(1) -중국산을 중심으로-

The purpose of present paper is to compare and analyze the quality of imported Chinese products with the Korean local products in terms of proximate composition, character of external appearance , ingredient composition of dried bracken , dried radish cubers, meju , dried pollack, dried mussel , and dried brown seaweed(Undaria puinnatidifida) which were imported between Oct., and Dec. 1992 and distributed in the market. Moisture recovery of dried products resulted in changed shape and incomplete moisture recovery due to an excessive drying in consideration of hygroscopic property in the course of distribution. The amounts of water soluble brown pigment were two times greater in Korean dried pollack and bracken than those of Chinese products. The content of volatile basic nitrogen (VBN) were twice in Chinese dried pollack, and this may be due to foregin odor from a long transport time and distribution process. The contents of aflatoxin in Korean products were not detectable and these of Chinese products were 5 $\mu\textrm{g}$(%) in dried pollack, bracken and radish cuber. the remaining agricultural chemicals were not detectable in all products. Because of poor technique and facilities, the external appearance of Chinese products especially dried mussels and dried pollack were not uniformed in size and color. Discoloration and foregin substance such as hair, dust were checked , Korean products were mostly packed in small size in PP or bag, and Chinese products were packed in bulk size and distributed as a bulk.
