# Cheese from milk of buffalo, fresh or processed

## 1. Scope and Applicability

This PCR applies to cheese whose milk origin is exclusively buffalo and that leaves the reporting factory as fresh/unripened cheese, ripened cheese, or processed cheese for direct consumption or further processing. It covers bulk, retail, food-service, brined, unbrined, unpackaged, and packaged market states when the declared reference product and foreground records identify the applicable state.

The category is milk-species specific. The foreground data package shall demonstrate buffalo origin for every milk and milk-derived input. A product containing milk, cream, curd, cheese, milkfat, milk solids, whey material, or another milk-derived ingredient from cattle, sheep, goats, or another non-buffalo species is not automatically covered. It requires an explicit classification determination based on the product as supplied and all contributing animal species; until that determination is documented, this PCR shall not be used as an exact category rule.

Products that are not cheese, plant-based analogues, whey products sold separately, cheese made exclusively from non-buffalo milk, and mixed-milk cheeses without an accepted category determination are excluded. Farm production of buffalo milk and production of purchased ingredients or packaging are represented by upstream datasets rather than repeated inside the cheese factory foreground boundary.

Codex product standards are used here to identify and describe applicable cheese states and dairy-origin claims. Their composition, quality, hygiene, additive, and labelling provisions are not converted into default life-cycle inventory quantities, yields, recipes, loss factors, energy demands, or emission factors. All such quantities shall come from site- and batch-specific records unless this PCR explicitly provides an applicable method formula.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Buffalo-milk cheese in the declared fresh/unripened, ripened, or processed market state |
| How much | 1 kg net cheese product at the reporting factory gate |
| How well | Conforms to the declared product specification and buffalo-only milk-origin claim; no product-quality threshold is used as an LCI factor |
| How long or cycle | One completed production lot through the declared factory-gate release point, including ripening, brining, packaging, and factory storage only when applicable |
| reference_flow_link | The functional unit is realized by the single Tiangong product flow and mass reference object below |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Cheese from milk of buffalo, fresh or processed `4b760369-5f64-47c7-b922-9dbe4b8abf98` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | milk animal species and buffalo-only evidence; mixed-milk determination if triggered; cheese state as fresh/unripened, ripened, or processed; named variety or product specification; salt and brine state; ingredients and processing aids; packaging format and packaged/unpackaged state; reference net-mass basis; factory-gate storage condition; production lot and reporting period |

When constructing a foreground data package, the items listed in `Required qualifiers` must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `measurement_reference_mass` | reference cheese output | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Measure the released reference cheese on the declared net-product basis. Exclude packaging mass and separately present free brine from the 1 kg cheese reference amount; inventory them separately. If commercial records use another basis, retain the original record and document the conversion. |
| `measurement_milk_species` | milk and milk-derived inputs | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Record each animal species and supplier lot separately. Do not merge non-buffalo milk-derived material into a generic milk total; any non-buffalo quantity triggers the mixed-milk classification rule. |
| `measurement_product_state` | reference product and intermediate cheese | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Preserve the measured state at each weighing point and declare whether mass is before or after draining, salting/brining, ripening, processing, and packaging. Do not apply a standard moisture, yield, or retention factor. |
| `measurement_brine` | salt and brine inputs and outputs | Mass or volume with measured density | kg or m3 | Record make-up salt, make-up water, purchased brine, recirculated internal brine, purge, carry-over, and wastewater separately. Convert volume to mass only with batch- or period-specific density evidence. |
| `measurement_energy` | electricity, fuels, steam, heat, cooling, and compressed air | Delivered energy or physical carrier quantity | kWh, MJ, kg, or m3 as recorded | Retain original meter or invoice units and conversion factors. Allocate common utilities only after separately metered process use has been exhausted; do not use a generic cheese-energy factor. |
| `measurement_packaging` | primary, secondary, and tertiary packaging | Mass or item count with measured item mass | kg | Record packaging by material and format. Convert item counts to mass using supplier specifications or measured lot-average item mass, and keep packaging outside the net cheese reference mass. |

## 5. System Boundary

The foreground boundary begins when buffalo milk and other purchased materials are received at the reporting cheese facility. It includes identity checks and reception, storage and preparation of milk, thermal treatment or standardisation when performed, coagulation and curd handling, whey separation, salting or brining, ripening, processed-cheese operations, packaging, factory storage, cleaning, refrigeration, on-site utility use, direct emissions, waste handling, and on-site wastewater treatment when these activities serve the declared product. Upstream production of buffalo milk, ingredients, energy carriers, water, packaging, and purchased services is represented by linked supplier-specific or appropriate secondary datasets. Distribution after the declared factory gate, retail, consumer use, and end-of-life are outside this foreground dataset unless a downstream lifecycle model adds them transparently.

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Buffalo milk and all other milk-derived inputs received at the reporting facility, identified by supplier, lot, animal species, physical state, and quantity |
| starting_condition_role | Upstream product inputs with linked production datasets; the cheese factory foreground starts at receipt |
| product_classification_scope | Buffalo-only cheese in CPC 3.0 subclass 22252; the cheese state may be fresh/unripened, ripened, or processed when declared |
| recursive_input_rule | Purchased buffalo cheese or curd used to make the reference product is recorded as an input with its own upstream dataset and is not recursively recreated inside this foreground dataset. Purchased mixed-species cheese or curd triggers classification determination before use of this PCR. |
| upstream_dataset_requirement | Link buffalo milk, purchased buffalo cheese/curd, other ingredients, energy, water, packaging, and external treatment or transport services to temporally, geographically, and technologically representative upstream datasets; disclose proxies |
| disclosure | Declare animal-species evidence, milk and milk-derived ingredient composition, cheese state, salt/brine state, ingredients and aids, packaging state, net-mass basis, facility and lot coverage, co-products, allocation, exclusions, and all upstream proxies |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_buffalo_origin` | all milk and milk-derived inputs | Include this product category only when supplier and batch evidence supports buffalo origin for every milk-derived input. Any non-buffalo input triggers an explicit classification determination before modelling proceeds. | `codex-cxs-206-1999`; `unsd-cpc-3-0` |
| `boundary_route_state` | foreground process selection | Include only process modules actually used by the declared route, but do not omit ripening, brining, processing, packaging, cold storage, cleaning, refrigeration, waste, or wastewater activities when they occur. | `codex-cxs-283-1978`; `codex-cxs-221-2001`; `eu-fdm-bat-2019` |
| `boundary_upstream_links` | purchased inputs and services | Represent production of received materials and purchased services with linked upstream datasets rather than duplicating them in the cheese factory foreground. | `eu-pef-2021` |
| `boundary_bat_applicability` | application of EU FDM BAT evidence | Use EU FDM BAT requirements or performance information only when the reporting installation and operating basis fall within the Decision's stated scope and the cited dairy condition applies. Never transfer facility-level or product-quality values into a universal cheese LCI. | `eu-fdm-bat-2019` |
