Abstract
|
|
|
In order to inhibit sprouting of garlics during the storage period and the extend their storage life, garlics were irradiated by gamma-rays (Co^(60)) and kept at room temperature. The effects of gammaradiation on sprouting inhibition, chemical contents during storage, and spoilage molds were investigated and the results are as follows.
1. Garlics obtained from Muan showed the shorter dormancy period and sprouted earlier than those from Dangjin.
2. Regarding the radioresistance, some differences were found between garlics from Muan and Dangjin.
3. The sprout of garlics from both areas was completely inhibited at 10 Krad and remarkable effect on sprouting was observed even with 5 Krad in case of garlics from Dangjin.
4. The rates of loss in moisture and weight were lower in irradiated lots than control.
5. Change of sugar content was not observed with γ-irradiation under 300 Krad.
6. Spores of Aspergillus niger and Aspergillus alliaceus were little germinated at a level of 300 Krad.
