密云地区的黄土坎鸭梨，栽种于明代，距今有600多年的历史。目前，以黄土坎为中心的鸭梨生产基地面积1.2万亩，年产650万公斤，窖藏后其香气更加浓郁。阳春三月梨花开，万树梨花开的盛景分外醉人，芬芳之气飘散数里。

黄土坎鸭梨品味独特，据测定，普通梨平均含糖量9%，而黄土坎鸭梨含糖量为13%-20%。这与其生长的地理环境有直接的关系。

首先黄土坎地区水土保持良好，雨水较多，年降雨量达650毫米，又紧邻密云水库和不老湖，水源丰富。

其次黄土坎村又坐落在燕落盆地的北边，背倚逶迤起伏的云峰山，日照充足，昼夜温差大，极适宜鸭梨生长。

第三黄土坎鸭梨生长在巨大的麦饭石矿床上，麦饭石中富含钼、锰、锌、铁、硼及稀土等无机盐，而梨树根系较深，容易吸收无机盐，且吸收量大，这就是为什么黄土坎鸭梨所含对人体有益无机盐高的主要原因。

据2003年10月14日国家食品质量监督检测中心对黄土坎鸭梨的检测报告，其中：总酸占0.14%，总糖占6.9%，灰份<0.1%，维生素C占4.1%，钙25.0mg/kg，锌0.76 mg/kg，钾958 mg/kg，硒0.01mg/kg，磷38.7 mg/kg。特别是硒，有较强的抗氧化功能。黄土坎所有的农作物都不同程度的含有“高抗氧”物质，而鸭梨含量最高。

长期食用富硒食品不但抗衰老，而且还有美容的功效。经有关专家实验证明，硒还有防癌抗癌的作用。长期食用黄土坎鸭梨还可增强体质，促进血液循环和赋予生命活力，排除体内陈积废物，对经痛、腰痛、肩痛、胃酸过多、寒症、乳腺炎、肝病、肾病、糖尿病、膀胱炎、高血压、便秘等病症都有一定治疗作用。
