Abstract

The effects of packaging materials, Ny/PE, PET/PE/Al, PET/PE/LDPE/CPP, and PET/Al/Ny/CPP, and packaging methods, atmospheric and vacuum packaging on physicochemical properties of onion Kimchi and rosemary-onion Kimchi were investigated. The maximun swelling days of packaging materials were increased more in rosemary-onion Kimchi than in onion kimchi, and they were in the order of PET/Al/Ny/CPP, PET/PE/Al, PET/PE/LDPE/CPP, and Ny/PE. The pH and reducing sugar contents of onion Kimchi and rosemary-onion Kimchi were decreased during storage. and those of lion Kimchi and rosemary-onion Kimchi packaged in PET/Al/Ny/CPP were higher than those in different packaging materials. Titratible acidity and vitamin C content of rosemary-onion Kimchi were lower than those of onion Kimchi, but there were no differences in the L and b values between two groups.
