Eggs, in shell, preserved or cooked

1. Scope and Applicability

This PCR applies to bird eggs that retain their shell and are preserved or cooked before leaving the processing facility. Covered routes include validated in-shell pasteurization, cooking in shell, food-grade oil coating, and alkaline or sodium-silicate preservation when the finished egg remains in shell. The foreground boundary begins with receipt of untreated shell eggs and ends with packaged product at the processing-facility gate after any required cooling and storage.

Fresh untreated eggs, hatching eggs, eggs broken for liquid or dried egg products, peeled cooked eggs, formulated egg foods, retail, consumer preparation, and packaging end of life are excluded. The bird species, treatment route, treatment validation basis, shell condition, package format, and storage condition must be declared. A data package may model more than one treatment route only as separately metered and reported product variants.

validate_treatment	Treatment batch	Confirm that monitored route conditions meet the approved cooking, pasteurization, or preservation specification and that deviations are excluded or corrected.	codex-cxc-15-1976; shenga-et-al-2010-in-shell-pasteurization
validate_mass_balance	Each process	Check measured inputs against product, waste, retained, and released outputs and require an explanation for material imbalance.	iso-14044-2006
validate_waste_emissions	Foreground outputs	Confirm separate records and destinations for wastewater, sludge, broken egg, eggshell, packaging scrap, each refrigerant release, and each direct combustion emission that applies.	iso-14044-2006
validate_bilingual_rows	English and Chinese PCR	Confirm identical ordered process ids, row ids, directions, flow types, controlled values, and source ids; confirm that every non-UUID Chinese selected-flow name is an accurate translation.
validate_range_evidence	Quantitative ranges	Do not add an empirical range unless at least two independent original sources are boundary-, unit-, product-state-, and normalization-compatible, or an authoritative source explicitly prescribes an interval.

10. Published Dataset Profile

Field	Value
dataset_role	Foreground processing dataset for preserved or cooked eggs retaining their shell
downstream_use	secondary_dataset; background_dataset after review and publication
allowed_use	Product carbon footprint, LCA, supply-chain modelling, facility improvement, and route comparison when product qualifiers and system boundary match
excluded_use	Fresh eggs, eggs not in shell, peeled cooked eggs, farm egg production, consumer cooking, or another treatment route without route-specific foreground data
required_metadata	PCR id and version; species; supplier geography; incoming condition; route and route share; cleaning route; treatment validation basis; package components; storage condition and duration; allocation method; reference year; facility geography
required_quality_disclosure	Meter coverage; calculated-versus-measured shares; unresolved Tiangong identities; mass-balance closure; treatment deviations; waste destinations; refrigerant identity and balance; source editions; data gaps
update_trigger	Material change in species mix, treatment technology or recipe, energy source, cleaning permission or practice, package format, refrigeration system, storage duration, allocation, supplier geography, or validated safety target
