Effect of γ Rays Irradiation Treatment on the Quality of Refrigerated Sanhua Plum Fruit
Different doses of 60Co γ rays were used to irradiate Sanhua plum before storage to observe the change of fruit quality of Sanhua plum during refrigeration.The hardness,soluble solids content,soluble protein content,titratable acid content and weight loss rate of the fruit were determined respectively,and the corresponding quality parameters were obtained.The experimental results showed that the high-dose irradiation treatment of 0.9 kGy could accelerate the ripening and softening of the fruit,and the soluble protein content decreased significantly,while the irradiation treatment at the low dose of 0.3 kGy had no significant effect on the hardness and soluble protein content of the fruit.Irradiation had a certain effect on the content of titratable acid and weight loss,and the greater the irradiation dose,the greater the effect,but had no significant effect on the soluble solids content.y rays irradiation treatment before storage is beneficial to maintain and improve the quality of fruits during the refrigeration process of Sanhua plum.
