# 冷冻水牛肉

## 1. 范围与适用性

本 PCR 锁定一条在屠宰与肉类加工一体化工厂内生产**包装去骨速冻水牛肉**的代表性出厂路线。前景边界始于工厂接收活水牛，依次包括待宰、屠宰与整修、胴体冷却、分割去骨、包装、鼓风速冻、冷冻贮藏和工厂卫生清洁。声明产品不是胴体、带骨肉、食用内脏、绞肉、机械分离肉，也不是上述产品的加权平均。

活水牛上游生产及进厂运输，电力、燃料、供水、化学品和包装材料生产，外运废物和废水处理，出厂运输、零售、解冻、烹调和消费均不属于前景过程；构建从摇篮到大门或全生命周期模型时，应作为递归上游或下游数据集连接。产品热中心在热稳定后必须达到 `-18 °C` 或更低，并在冷冻贮藏中保持 `-18 °C` 或更低（`fao-who-cxc-8-1976`）。

## 2. 产品类别识别

| 字段 | 值 |
| --- | --- |
| canonical_pcr_id | `pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.meat-fish-fruits-vegetables-oils-and-fats.meat-of-buffalo-frozen` |
| classification_refs | CPC 3.0 `21132`，“Meat of buffalo, frozen”（`unsd-cpc-3-0-2025`） |

CPC 解释性说明 PDF 存在内部矛盾：类别标题和排除项指向冷冻水牛肉，但一处纳入文字写作“fresh or chilled”。本 PCR 遵循官方类别标题及其对鲜或冷藏水牛肉的明确排除，并披露该矛盾供评审（`unsd-cpc-3-0-2025`）。
