Abstract: In order to find the most appropriate way to prolong the shelf life under the condition of room temperature,this paper was to study combined short wave ultraviolet light(UV-C) irradiation treatment with different single or composite coating antistaling agent processing of peach fruit preservation effect.Using the phoenix honey peach in Jiangsu Zhangjiagang City as the experiment materials,with 20 W UV-C lamp for processing(irradiation dose:1 kJ/m2,irradiation distance:25 cm,irradiation time:3 min),after UV-C processing the peaches were grouped respectively for lysozyme,ascorbic acid,sodium alginate,and the three kinds of fresh-keeping agent composite coating processing,a total of 4 kinds of solution at room temperature(28±3)℃ conditions for preservation,span test for 14 d,every 2 d measuring related physiological and biochemical indexes.UV-C treatment combined with preservative coating could effectively reduce the phoenix honey peach rot,obviously delay the rising trend of malondialdehyde(MDA),polyphenol oxidase(PPO),and saved the fruit soluble solids content,single preservative treatment effect was not obvious difference; "UV-C+lysozyme+ascorbic acid+sodium alginate" was the best effect of peach fresh-keeping compound processing,decay index,the weightlessness rate and total soluble solids in 14 d were lower than the control group 73.02%,67.16% and 27.97%,respiratory peak by 4 d delay to 10 d,hardness,increased of MDA and the activity of PPO increased rate was lower than the control group 69.37%,45.06% and 19.65% respectively.UV-C treatment combined with ascorbic acid,sodium alginate and lysozyme processing method of the compound fresh-keeping agent could effectively reduce the phoenix honey peach under the condition of the real degree of rotting,delay the malondialdehyde(MDA) and the rise of polyphenol oxidase(PPO),significantly delayed respiratory peak,could be used as a new type of peach fruit under normal temperature preservation methods to promote the widespread utilization.
