【摘要】 本文重点论述了对保鲜柚果的采收要求及采后处理技术。研究结果表明:用于保鲜的柚果采收成熟度必须达到8.5~9.0成熟,才能体现柚果应有的风味,采摘时用果剪沿果蒂处齐平剪下,并要注意防止柚果碰伤和挤压伤。柚果采收后应在常温下放置48h,以平衡柚果温度。然后入冷库预冷,预冷时必须在72h之内将柚果温度降到5℃以下。之后分装入冷库贮藏。柚果的最适冷藏温度3℃~5℃、相对湿度80%~90%;保鲜柚果出库时应缓慢升温,每天升温5℃~8℃,升温后分拣分级纸箱包装。出库后销售期在10d之内可常温运输,若销售期超过10d,则必须冷藏运输,冷藏车内温度与冷库内温度相同,到达销售目的地后可在销售前5d出库缓慢升温。没有碰伤和挤压伤的柚果商业冷藏保鲜期可达150d~210d。更多还原

【Abstract】 Investigations into harvesting standards and postharvest technology for fresh pomelos are presented.Results indicate that fresh pomelos for cold storage should be harvested at around 85 to 90 percent of full ripeness to ensure the fruit will develop its characteristic aroma.Precautions must be taken by the picker whilst harvesting pomelos,such as collecting fruit by cutting the stalk horizontally and preventing bruising and crushing of the fruit.Harvested pomelos should remain at room temperature for 48 hours to achieve temperature equalization throughout the whole fruit body.A rapid pre-cooling should then be applied to ensure the fruit temperature drops below 5℃ within 72 hours before cold storage.Whole pomelos should be stored at 3℃ to 5℃,with a relative humidity of 80%to 90%.When removing pomelos from the cold store,it is recommended to increase the fruit temperature by 5℃ to 8℃ per day.Pomelos that are graded,packed in corrugated casing and distributed under normal temperature conditions need to be sold within 10 days.Otherwise,refrigerated transportation is required to keep fruit at the same temperature as the cold store until it reaches market,where the temperature can be gradually increased five days ahead of sale.Through the study,it can be concluded that the commercial cold storage period of healthy pomelo fruit(no bruising or crushing) is between 150 and 210 days.更多还原
