摘要:
分别采用剂量为0、1、2、3、4、5、6 kGy的电子束辐照大米样品,考察其对大米品质的影响。结果表明:不同剂量的电子束辐照对大米的水分含量和浸泡吸水率无显著影响(P>0.05);随着辐照剂量的增加,大米的加热吸水率、体积膨胀率显著下降(P<0.05);辐照剂量显著影响米饭的蒸煮品质(P<0.05),剂量为5 kGy时蒸煮米饭出现明显的褐变。电子束辐照大米的剂量不宜超过2 kGy,以1 kGy的辐照剂量较佳。

Abstract:
Rice was irradiated by electronic beam at respective doses of 0, 1, 2, 3, 4, 5 and 6 kGy to examine the effect of high-energy electron beam irradiation on cooking quality of rice. The results indicated that electron beam irradiation had no significant impact on the moisture content or water-absorbing capacity of rice (P > 0.05). The water-absorbing capacity and volume expansion of rice under cooking conditions dropped markedly with the increase of irradiation dose (P < 0.05). Electron beam irradiation affected the cooking quality of rice significantly (P < 0.05). The rice subjected to electron beam irradiation at 5 kGy exhibited noticeable browning during subsequent cooking. This study found that the dose of electron beam irradiation should not exceed 2 kGy and that the preferable dose is 1 kGy.
Key words: rice, irradiation, color aberration, texture profile analysis, eating quality
