压差预冷结合高分子隔热保温膜处理对甜樱桃货架品质的影响
Effect of forced-air precooling combined with high-molecular thermal insulation film treatment on quality of cherry during shelf-life period
摘要
Abstract
To explore the effect of forced-air precooling combined with high-molecular thermal insulation film treatment on the quality of cherries during the shelf-life period,sweet cherries were selected as the test subjects.Following forced-air precooling conducted in the production area,the cherries were packaged using high-molecular thermal insulation film.After simulating 24 hours of cold chain circula-tion,they were placed on shelves at room temperature(25±1)℃,with a relative humidity of 80%to 85%for 7 days.The shelf quality and physiological indicators of the cherries were measured,simple cold chain cold(storage pre-cooling combined with cotton blanket insu-lation)in actual production serving as the control.The shelf quality and physiological indicators of the cherries were subsequently meas-ured.Results indicated that,compared to the simple cold chain,forced-air precooling combined with high-molecular thermal insulation film treatment not only reduced the pre-cooling time by 10 hours but also delayed the rapid rise in cherry temperature during transporta-tion.Additionally,it maintained the high hardness of the fruit,elevated the content of titratable acid,soluble sugar,and vitamin C,and suppressed the rapid increase in respiration rate and ethylene release rate.Furthermore,its relative conductivity,malondialdehyde,water-soluble pectin(WSP)content,cellulase(Cx),polygalacturonase(PG),β-glucosidase(β-Gal),and pectin methyl esterase(PME)activity were significantly lower than control(P<0.05).In conclusion,the combination of forced-air precooling and high-molecular ther-mal insulation film treatment can effectively enhance the post-harvest cold chain level of cherries and maintain shelf-life quality.关键词
