Abstract

ABSTRACT After harvest, higher respiration rate in apricots limit their postharvest with extensive losses in fruit quality. Therefore, effect of different pre-storage treatment of modified atmosphere packaging (MAP) were studied on the shelf life and quality of apricot cv. ‘Shahroudi’ fruit. Experimental treatments were control (air), and active MAP includes: MAP1 (10% O2/20% CO2), MAP2 (20% O2/10% CO2), MAP3 (5% O2/80% CO2), MAP4 (80% O2/5% CO2) and MAP5 (40% O2/20% CO2), all treatments were balanced by N2. After 6 days of pre-storage treatments, fruits were unpacked, repacked and then were stored at 2°C and 85% relative humidity for 28 days. Results indicated that MAP5 and MAP3 treatments significantly reduced weight loss and total soluble solids, and maintained fruit hardness in comparison with other treatments. High CO2 treatment improved postharvest traits of apricot. Interestingly, high CO2 in combination with high O2 (active MAP5) improved the sensory evaluation as scored the best treatment by panelists, and also maintained better chemical properties such as total phenolic compounds, total carotenoids, and vitamin C. In addition, shelf life of fruit in active MAP5 (29.6 days) significantly extended followed by active MAP3 (27.6 days), compared to control (14.6 days) without signs of decay until the end of the storage period. Overall, it can be concluded that the pre-storage treatment of fresh apricot fruit in an atmosphere with high O2 (40%) and CO2 (20%) concentrations had a positive effect on the post-harvest quality attributes and shelf life of apricot cultivar ‘Shahroudi,’ and can be suggested as an effective and practical method to prolong its postharvest life.
活性气调包装预处理对冷藏杏果保质期和品质属性的影响
摘要:收获后,杏较高的呼吸速率限制了采后的果实质量。为此,研究了气调包装(MAP)的不同贮藏前处理对杏的保质期和品质的影响。沙赫鲁迪的水果。实验处理为对照(空气),活性MAP包括:MAP1 (10% O2/20% CO2)、MAP2 (20% O2/10% CO2)、MAP3 (5% O2/80% CO2)、MAP4 (80% O2/5% CO2)和MAP5 (40% O2/20% CO2),所有处理均以N2平衡。贮藏前处理6 d后,将果实拆封、重新包装,在2℃、85%相对湿度条件下贮藏28 d。结果表明,与其他处理相比,MAP5和MAP3处理显著降低了果实失重和可溶性固形物总量,并保持了果实硬度。高CO2处理改善了杏采后性状。有趣的是,高CO2和高O2(活性MAP5)组合提高了感官评价,被小组成员评为最佳处理,并且还保持了更好的化学性质,如总酚化合物,总类胡萝卜素和维生素c。此外,活性MAP5(29.6天)的水果保质期显著延长,其次是活性MAP3(27.6天),与对照组(14.6天)相比,直到储存期结束都没有腐烂迹象。综上所述,在高浓度O2(40%)和CO2(20%)的环境中对杏鲜果实进行贮藏前处理,对杏品种“沙乌地”采后品质属性和货架期均有积极影响,是延长其采后寿命的一种有效而实用的方法。

期刊介绍: The International Journal of Fruit Science disseminates results of current research that are immediately applicable to the grower, extension agent, and educator in a useful, legitimate, and scientific format. The focus of the journal is on new technologies and innovative approaches to the management and marketing of all types of fruits. It provides practical and fundamental information necessary for the superior growth and quality of fruit crops. This journal examines fruit growing from a wide range of aspects, including: -genetics and breeding -pruning and training -entomology, plant pathology, and weed science -physiology and cultural practices -marketing and economics -fruit production, harvesting, and postharvest
