回答1:

梨的贮藏方法与苹果基本相同,但要注意不同种类、不同品种的梨,具体贮藏方法有不同。一些肉质较粗,石细胞多,皮厚,蜡质层厚,含酸量高的梨,如字宁的安梨、花盖梨、河北的酸梨、红霄梨、山档的长把梨、香水梨,山西的笨梨、黄梨、油梨等,极耐贮藏,采用平地堆藏、筑畦堆藏和土窖筐装垛藏或搭囤藏等简易贮藏均可。共中土窖贮的梨,采后经挑选先装筐在田间树下或阴凉处预贮一段时间,然后选天凉时将筐加盖封紧,再入窖,窖底铺细砂,垫秫秸把,上面码筐4~5层,依窖宽不同,一般可排3~4行,中间留通道。囤藏是在窖内铺砂做20~30厘米囤底,然后有苇席圈做囤,囤内可散堆放1米多中间高,周围低的梨。采用简易方法贮藏时应注意根据外面天气变化,掌握好贮堆(垛、筐)内的梨果温度,防止前、后期温度过高伤热,中期温度过低受冻。大多数品种的梨可采取纸箱装,入冷库码垛冷藏。控制适宜的温湿度即可长期贮藏。其中鸭梨冷藏分期逐步降温的具体做法是:入库时温度可在12℃左右,保持每3天降1℃降至10℃时,保持5天,再每3天降1℃,降至6℃时,保持10天,再每3天降1℃至1℃时,即可恒温贮藏,控制相对湿度95%以上,可贮至次年的4~5月。应用纸包装、聚乙烯塑料袋或透气膜小包装,塑料帐密封调气贮藏等不仅可以减少自然损耗,而且可以推迟后熟,延长贮期,提高保鲜质量。南果梨应适期晚采,最好在9月中下旬采,装纸(木、塑)箱,在冷库垛藏。可装透气膜袋贮,既保湿,又可调节气体,效果更好。贮温可控制在-1℃~0℃,相对湿度90%~95%。据沈阳农业大学报道:南果梨在0℃低温冷库中,采取5%~8%的氧浓度和5%的二氧化碳浓度贮,比普通储藏具有明显效果。鸭梨在冷库中气调贮藏时,对二氧化碳极为敏感,将氧浓度维持在12%~14%,二氧化碳在1%以下较好,贮藏期间易发生黑心病

  将鲜梨用2~3层软纸一个一个分别包好,然后装入纸盒当中,放进冰箱内的保鲜格中,过大约7天后取出来去掉包装纸,装入塑料袋中,不扎口,再放入冰箱冷藏室上层,温度调到0度左右,一般可存放两个月。
  梨(Pear),水果名称,蔷薇科梨属植物,多年生落叶乔木果树,叶子卵形,花多白色,一般梨的颜色为外皮呈现出金黄色或暖黄色,里面果肉则为通亮白色,鲜嫩多汁,口味甘甜,核味微酸,凉性感。梨分布在华北、东北,西北及长江流域各省。7~9月间果实成熟时采收,可鲜用或切片晒干。和冰糖一起煲水,可治疗咳嗽。
  营养价值
  梨果鲜美,肉脆多 汁,酸甜可口,风味芳香优美。富含糖、蛋白质、脂肪、碳水化合物及多种维生素,对人体健康有重要作用。梨子具有清肺养肺的作用。多吃梨的人远比不吃或少吃梨的人感冒机率要低,所以有科学家和医师把梨称为“全方位的健康水果”或“全科医生”。由于社会发展空气污染比较严重,梨可改善呼吸系统和肺功能,有润肺的功效,可以降低肺部受空气中的灰尘和烟尘的影响。梨果还可以加工制作梨干、梨脯、梨膏、梨汁、梨罐头等,也可用来酿酒、制醋。梨果还有医用价值,可助消化、润肺清心,消痰止咳、退热、解毒疮的功效,还有利尿、润便的作用。梨木细致,软硬适度,是雕刻印章和高级家具的原料。梨的含糖量在15%以下,每天的食用量可在300-500克,糖尿病人可以食用。梨肉脆汁多、酸甜可口,营养丰富,有益健康。
