摘要:
以七八成熟丰香草莓果实为材料,贮前用热蒸汽处理10、20、30和40 s,研究其对4℃冷藏下果实的贮藏效果以及贮藏过程中某些生理指标的变化。结果表明,贮前热蒸汽处理10和20 s可以明显抑制贮藏期间果实花青素积累,降低果实失重率、腐烂指数和呼吸速率,维持较高的SOD活性,降低LOX活性、纤维素酶活性、产生速率和MDA含量,明显延长了果实贮藏时间。而贮前热蒸汽处理30和40 s的果实受到热伤害,影响了果实的外观品质,甚至缩短了果实贮藏寿命。
Abstract:
The preservation and physiological indexes of strawberry fruits(Fragaria ananassa Duch cv. ’Toyonoka’)stored at 4 ℃ were investigated for the effects of heat-steam treatment for 10, 20, 30 and 40 s. The results indicated that heat-steam treatment for 10 s and 20 s significantly inhibited anthocyanin accumulation, weight loss, decay index and respiratory rate of the postharvested fruits, and maintained higher activities of superoxide dismutase(SOD), but decreased the activities of lipoxidase(LOX), cellulase, the production rate and MDA content. Therefore, heat-steam treatment was helpful for strawberry to prolong the storage life. However, heat-steam treatment for 30 and 40 s injuried fruits, which degraded external qualities and shortened preservation of the strawberry fruits.
