# Refrigerated Pasteurized Liquid Whole Egg

## 1. Scope and Applicability

This PCR guides foreground data package construction for one deliberately narrow product form: unformulated refrigerated pasteurized liquid whole chicken egg, with yolk and albumen retained in the natural whole-egg proportion, filled in a food-grade bulk container and released at the processor cold-store gate.

It covers shell-egg receipt, optional shell washing, breaking, inspection, filtration, whole-egg blending or homogenization, thermal pasteurization, rapid cooling, bulk filling, refrigerated storage, cleaning-in-place (CIP), and foreground waste and wastewater handling. The reference product is not frozen, dried, cooked, sweetened, salted, stabilized for ambient storage, fractionated, or reformulated.

Separate yolk, albumen, yolk-enriched blend, egg-white blend, frozen liquid, dried powder, cooked egg, chemically preserved product, high-pressure processed product, and manothermosonication routes are excluded. A dataset must not average any of those routes with the selected liquid-whole-egg route. Any facility using a materially different product form or lethality route requires a separately declared product-specific dataset and reviewed applicability decision.

| classification_refs | CPC 3.0 `23993`, `Eggs, not in shell, and egg yolks, fresh or preserved; egg albumin` |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | refrigerated pasteurized liquid whole chicken egg |
| How much | 1 kg net product |
| How well | unformulated; natural whole-egg yolk-to-albumen proportion; validated thermal pasteurization; no visible shell or foreign matter; product temperature at or below 4 °C at gate |
| How long or cycle | one production batch through cold-store gate; storage duration declared in hours |
| reference_flow_link | Reference amount and product flow below |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg net product |
| Reference product flow | Eggs, not in shell, and egg yolks, fresh or preserved, egg albumin `8ee52550-935f-4209-b758-c2d060bba326` |
| 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 | species=chicken; product_form=liquid_whole_egg; formulation=unformulated; lethality_route=thermal_pasteurization; preservation_state=refrigerated_not_frozen; gate=processor_cold_store; product_temperature_c; storage_duration_h; packaging_route=ldpe_lined_reusable_stainless_steel_bulk_tote; thermal_supply_route; refrigeration_refrigerant=R717_ammonia |

All required qualifiers must be declared in dataset metadata or equivalent machine-readable fields. The Tiangong flow identity spans the wider CPC subclass; these qualifiers narrow the dataset to the single product form governed by this PCR.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Normalize to net liquid whole-egg mass, excluding the bulk tote and liner. |
| `whole_egg_identity` | raw, filtered, pasteurized, and final egg streams | Mass and formulation record | kg | Keep yolk and albumen together in the natural whole-egg proportion; do not combine separate yolk or albumen production records. |
| `pasteurization_schedule` | thermal pasteurization | temperature and minimum residence time | °C and min | Record the validated time-temperature schedule and flow-diversion evidence. For unformulated whole egg below 24% solids, 60 °C for 3.5 min is an official baseline; an alternative schedule requires documented validation and jurisdictional acceptance. |
| `cold_chain_temperature` | post-pasteurization cooling and storage | temperature and duration | °C and h | Record continuous or batch-linked temperature history; the declared product at gate must be at or below 4 °C. |
| `electricity_measurement` | each electricity card | Energy | kWh | Use submetered electricity by unit operation; allocate a shared meter only by documented operating time and rated load or a validated mass-throughput rule. |
| `thermal_energy_measurement` | purchased steam, hot water, or on-site natural-gas route | Energy or carrier quantity | MJ, kg steam, m3 hot water, or kg fuel | Preserve the original carrier quantity, temperature/pressure where applicable, lower heating value for fuel, and conversion formula. |
| `water_measurement` | shell washing, cooling, CIP, and wastewater | Volume | m3 | Keep intake, recirculated, recovered, and discharged water separate; do not record gross recirculation as net withdrawal. |
| `refrigerant_measurement` | R717 ammonia system | Mass | kg | Use charge, purchases, additions, recovery, and disposal records; calculate losses by refrigerant mass balance. |
| `packaging_measurement` | LDPE liner and reusable stainless-steel tote | Mass and item count | kg and item-use | Record liner mass per batch and tote identity, tare, capacity, trip count, and reuse allocation separately. |
| `pollutant_measurement` | water and air elementary flows | Mass | kg | Calculate each named substance separately from measured concentration and discharge volume or from a documented carrier-specific factor. |

## 5. System Boundary

The foreground boundary begins with accepted shell eggs and utility/material inputs crossing the processor gate and ends with refrigerated pasteurized liquid whole egg in the declared bulk tote at the processor cold-store gate. Upstream shell-egg production, electricity generation, purchased steam production, natural-gas supply, water supply, chemical manufacture, and packaging manufacture are linked as upstream datasets rather than recreated in this foreground package.

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_required_operations` | foreground process map | Include receipt/breaking, filtration/blending, thermal pasteurization/rapid cooling, bulk filling/refrigerated storage, and CIP/wastewater handling. | `codex-cxc-15-1976`, `usda-fsis-egg-products`, `beitia-et-al-2024` |
| `boundary_raw_treated_separation` | facility and inventory scope | Keep raw shell-egg and untreated-liquid operations physically and record-wise separate from pasteurized product, packaging, and finished cold storage. | `codex-cxc-15-1976`, `cfia-egg-preventive-controls` |
| `boundary_product_form_gate` | all datasets | Include only unformulated thermally pasteurized refrigerated liquid whole egg; reject any average with yolk, albumen, frozen, dried, cooked, stabilized, or non-thermal routes. | `usda-fsis-egg-products`, `cfia-egg-preventive-controls` |
| `boundary_thermal_supply_gate` | pasteurization and CIP heat | Select either purchased steam or on-site natural-gas heat for each reporting period. If both are used, meter them separately by batch; never substitute a weighted generic heat carrier. | `jrc-fdm-bref-2019` |
| `boundary_refrigeration_gate` | cooling and cold storage | The representative route is an R717 ammonia system. Other refrigerants are outside this route and require separately named atomic input and emission cards before use. | `ipcc-2019-refrigeration` |
| `boundary_packaging_gate` | bulk filling | Use the declared LDPE-lined reusable stainless-steel bulk-tote route; exclude consumer cartons, HDPE pails, bag-in-box, tanker, and aseptic ambient packaging from this dataset. | `beitia-et-al-2024` |
| `boundary_wastewater_gate` | wastewater outputs | Select off-site treatment as one wastewater waste flow or on-site treatment with separately measured direct-to-water elementary flows. Do not report both for the same wastewater mass. | `us-epa-egg-processing-waste-1971` |

### Boundary Abstraction

| starting_condition_role | upstream_product_input_and_foreground_batch_identity |
| product_classification_scope | current CPC 3.0 subclass `23993`, narrowed to unformulated refrigerated thermally pasteurized liquid whole chicken egg |
| recursive_input_rule | purchased untreated liquid whole egg in the same CPC subclass must be recorded as an upstream input dataset with treatment_status=untreated and must not be represented as the finished reference product |
| upstream_dataset_requirement | supplier-specific shell-egg dataset or disclosed proxy with species, production system, geography, date, accepted mass, reject mass, and allocation status |
| disclosure | disclose shell-egg source, whole-egg formulation, pasteurization schedule, cooling record, thermal supply route, R717 charge and loss, packaging route, cold-store duration, coproduct fate, wastewater route, and every provisional estimate |
