포장 필름과 저장 온도 조건에 따른 양송이버섯의 품질 변화

Abstract

This study was conducted to investigate the effects of temperature and packing film with varying oxygen transmission rate (OTR) on the quality of Agaricus bisporus (mushrooms) to determine the optimum modified atmosphere package. Mushrooms were packed using 10 µm polyvinyl chloride (PVC), and 30 µm oriented polypropylene (OPP) films with the OTR ranging from 1,000 to 20,000 mL/m2/day/atm (OPP1000, OPP6000, OPP10000, and OPP20000). The quality parameters including weight loss, gas composition, cap opening rate, stipe elongation, firmness, and color of mushrooms were monitored at the following temperatures: 4℃, 8℃, 12℃, and 20℃. Overall, the mushrooms packed in OPP films showed less change in weight loss, cap opening rate, stipe elongation, and firmness than those of the control, however, these effects differed with the temperature and film OTR. Among the OPP films, OPP20000 did not exhibit any effect with respect to tissue growth inhibition. OPP1000 and OPP6000 were the most effective in suppressing the cap opening rate and stipe elongation but induced tissue damage and water soaking in the internal section. In contrast, the mushrooms packed in PVC film showed less change in weight loss, cap opening rate, and stipe elongation than those of the control, and browning of inside and outside of mushroom was less than that mushroom packed in OPP film.
