This study was carried out in order to investigate the effect of MA packaging material on quality and shelf life of ferulae mushroom (Pleurotus ferulae) at 1, 8, and 24℃ storage temperatures. We found that the fresh weight loss was less than 1.5% in all temperatures (1, 8, and 24℃) and non-perforated breathable films (1,300 cc, 3,000 cc, 5,000 cc, 7,000 cc, 10,000 cc, 15,000 cc, 20,000 cc, and 40,000 cc/ ㎡ㆍdayㆍatm oxygen transmission rate) treatments. The proper MA packaging material of ferulae mushroom was 1,300 cc and 3,000 cc films at 1℃ storage. Because 1,300 cc and 3,000 cc films showed proper level, 15% carbon dioxide and 5% oxygen concentration for MA storage, although the shelf life was higher in 1,300 cc (42 days) than 3,000 cc (38 days), and the ethylene concentration as well as off-order showed lower in 3,000 cc than 1,300 cc film. The 3,000 cc film was the most suitable for ferulae mushroom storage at 8℃, because atmosphere composition in package was not statistically significantly different among the film treatments. In addition, 3,000 cc film showed the second low ethylene concentration and the longest shelf-life of 19 days. The ferulae mushroom stored at 25℃ showed a vigorous respiration and resulted in an extreme CA condition in package at 5∨th day after storage, and showed the highest visual quality in 1,300 cc film. As the shelf life of ferulae mushroom at 1℃ and 8℃ storage were 8 times and 4 times longer than at 25℃ storage respectively, so the ferulae mushroom should be stored and distributed in cold chain system.
