Abstract
|
|
|
Korean Paldal variety rice, harvested November and hulled into polished and unpolished forms in April, 1969, packed in the straw bags and the kraft paper bags. Being irradiated with 10, 30 and 50 krad γ-ray, the samples were stored at room temperature for testing infestation, uric acid content, fat acidity, riboflavin content and panel test. The results are as follows.
1. The kraft bag lot with polished rice or unpolished rice manifested the apparent disinfestation with 30∼50 krad irradiation. On the other hand, in the straw bag lot the irradiation effects on disinfestation were weakened through summer on account of the second contamination.
2. The changes of uric acid content in rice were proportional to the state of infestation.
3. Fat acidity, which has a close relation with the rancidity of fat in rice, increased during storage and showed some increasing tendency in the irradiated lot with 30∼50 krad.
4. In comparison with the control lot, riboflavin content was not affected by 50 krad irradiation.
5. With 10, 30 and 50 krad dose, the irradiated lot should have no significant difference in taste, odour, color and viscosity for the panel test.
