广式月饼的辐照保鲜

Irridated preservation of Guangdong style mooncake

广式月饼经2．5KGY、5．OKGY、7．5KGY、10．OKGY四个剂量的r－射线辐照处理,辐照过的月饼置于28°C培养箱中,定期测定月饼中微生物总数、理化指标以及感官质量指标。研究结果表明:5．OKGY、7．5KGY剂量的r－射线能有效地抑制月饼中的微生物,使月饼的保鲜期得以延长,而对月饼的AV值、POV值以及口感等质量指标影响不大。

Irradiation treatments for moon cake were done with 2.5KGY、5.0KGY、7.5KGY、 10.0KGY doses. Samples were stored at 28℃. During storage the samples were periodically detected for total amount of microorganism and moon cake quality. Results showed that microorganism growth in irradiated samples were obstructed; there was no significant difference between radiation treatment and contrast on amount of AV and POV.
