변형기체포장이 흑미 첨가 기능성 찐빵의 저장성에 미치는 영향

Modified atmosphere packaging (MAP) was applied to steamed bread added with black rice in 10%. In terms of storage stability, the steamed bread was found to be susceptible to microbial spoilage and could be helped in its preservation and shelf life extension by MAP. According to microbial and sensory quality criteria, the product shelf life was determined as < 5 days for air package, 5 days for 100% N2 package, 8 days for package of 60% CO2/40% N2, and 15 days for 100% CO2 package. Even though MAP condition with CO2 inclusion was effective in extending the shelf life based on microbial quality, it did not affect the staling of the bread.
