上海地区学生午餐营养及供应链状况研究

目的 了解上海地区学生午餐营养及供应链状况，为改善学生午餐营养状况，保障食品供应安全提供参考。方法 分析上海市学生午餐的营养、卫生、供应链、加工工艺等状况，采用定期抽检的方法，应用SNHAS对营养素、食品安全、感官进行综合评价。结果 各单位样本综合评价均合格，其中热量、蛋白质、脂肪均能达到或超过DRIs供给量的要求，但矿物质中Ca(仅为AI的32％)、视黄醇当量(仅为AI的57％)供给量较低。对供应链及卫生状况的分析表明，大型企业对各个环节控制严格，产品质量较好，但也存在保存时间过长等问题。结论 应进一步完善供应体系，建立高效的质量控制体系，推广营养配膳系统。
