Vegetables provisionally preserved

food-products-beverages-and-tobacco-textiles-apparel-and-leather-products

1. Scope and Applicability

This PCR covers factory-gate production of vegetables that are provisionally preserved as an intermediate product, remain unsuitable in that state for immediate consumption, and require further processing before consumption. It covers receipt and preparation of the vegetable, exactly one declared provisional-preservation route, and storage and dispatch. It excludes fresh, frozen, dried, ready-to-eat, canned or otherwise finally preserved vegetables and vegetables whose defining preservation route is vinegar or acetic acid.

The canonical category follows CPC 3.0 subclass 21330. The Tiangong flow Tomato is a narrower CPC-21330 representative: UUID 4dc258f9-c5fc-47d7-821e-12526fe6b5d7 may identify only tomato datasets. A dataset for another vegetable requires a semantically appropriate Tiangong product flow before publication; the Tomato UUID shall not be reused for that dataset.

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	Report 1 kg on the declared gross, net or drained product-mass basis and use that same basis for every normalized inventory amount.
component_mass_separation	vegetable and accompanying preservation medium	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Measure or calculate vegetable mass and accompanying-medium mass separately; disclose whether either component is included in the reference amount.
batch_normalization	all foreground inputs and outputs	applicable flow property	per kg reference product	Normalize batch totals by compliant reference-product mass at factory-gate handover; do not normalize by incoming raw-vegetable mass.

boundary_route_exclusivity	preservation route	Select exactly one route for each modelled lot: solution_preservation or gas_non_solution_preservation. Do not model both as simultaneously occurring. A genuinely combined treatment is outside this candidate PCR until reviewed route-specific evidence expands the scope.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid	route and process-specific burdens	Avoid allocation by separately recording preparation, the selected preservation route, storage and dispatch, and by submetering or subdividing shared operations where feasible.	eu-pef-2021-2279
allocation_physical	inseparable shared operations	If subdivision is not feasible, allocate by a documented relevant physical relationship that reflects causality, such as metered operating time, treated mass or occupied storage capacity and duration. Report the factor and all quantities used.	eu-pef-2021-2279
allocation_other_relationship	remaining multifunctionality	Use another relationship, including economic allocation, only after documenting why subdivision/system expansion and a relevant physical relationship are not feasible; disclose prices, period and sensitivity.	eu-pef-2021-2279
allocation_rejects	vegetable rejects, spent solution and treatment residues	Treat a stream as waste and assign its treatment burden to the foreground unless a demonstrated product function and destination support co-product treatment; do not claim an avoided burden by default.	eu-pef-2021-2279

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_reference_normalization	every batch inventory amount	normalized amount = batch amount / compliant factory-gate product mass on the declared basis × 1 kg	applicable collection protocol; cp_final_product_mass	amount per kg reference product	eu-pef-2021-2279
calc_component_mass	shipped solution-route product	declared product mass = measured vegetable mass + measured accompanying-medium mass only when that medium is included by the declared mass basis	cp_solution_product_mass	kg declared product and separate component fractions
calc_route_mass_balance	each foreground process	reconcile measured inputs = product outputs + waste outputs + direct releases + measured inventory change; report residual and facility acceptance rationale	process-specific mass protocols	batch mass-balance residual and normalized flows
calc_agent_release	direct treatment-agent release	release = charged agent - agent retained in product - recovered agent - captured agent - closing inventory adjustment, separately by substance and compartment	cp_gas_route_inputs; cp_treatment_agent_release	kg direct elementary flow
calc_unmetered_energy_screening	temporary candidate energy estimate	estimate = sum(nameplate power × logged operating time × documented load factor) / compliant product mass; apply only to declared equipment and operating scenario, and never together with metered energy for the same interval	equipment nameplates; operating logs; documented load-factor rationale; cp_final_product_mass	provisional kWh/kg reasoned estimate

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	reference and intermediate product flows	Demonstrate semantic match between vegetable identity and selected Tiangong flow. UUID 4dc258f9-c5fc-47d7-821e-12526fe6b5d7 is acceptable only for tomato datasets; another vegetable needs an appropriate flow before publication.	product specification; flow review; batch genealogy
dq_completeness	foreground inventory	Include all known inputs and outputs, with exclusions and residual mass-balance terms documented.	protocol coverage matrix; mass balance; eu-pef-2021-2279
dq_representativeness	activity data	State technological, geographical and time-related representativeness and precision; representative batches shall span declared operating modes, route, formulation and storage conditions.	sampling rationale; batch list; DQR record; eu-pef-2021-2279
dq_measurement	mass, water, agents, energy and releases	Retain calibration status, measurement method, unit conversions and batch linkage; do not mix gross, net and drained mass bases.	calibration certificates; raw records; reconciliation sheets
dq_food_control_records	formulation and preservation controls	Retain the actual product description and applicable GHP/HACCP monitoring evidence for water suitability, sanitation, formulation, time, temperature, pH or other identified controls.	approved specification; control records; codex-cxc-1-1969
dq_reasoned_estimate_replacement	unmetered energy screening	Mark the estimate provisional and limited to the declared equipment scenario. Replace it when representative-batch metering, a validated facility energy balance or reviewed transferable evidence becomes available; publication shall not rely on an unreviewed temporary estimate.	estimate sheet; replacement decision; meter or reviewed evidence

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_flow_semantics	reference product flow	Fail if the dataset product is not tomato while the reference product UUID remains 4dc258f9-c5fc-47d7-821e-12526fe6b5d7; require a verified semantically appropriate flow before publication.
validate_route_exclusivity	process selection	Require exactly one of solution_preservation and gas_non_solution_preservation for each lot; fail on neither, both, or an undeclared combined route.
validate_product_state	category applicability	Require evidence that the output is provisionally preserved, unsuitable in that state for immediate consumption and intended for further processing; otherwise reject CPC-21330 applicability.	unsd-cpc-v3-21330
validate_reference_mass_basis	reference and normalized amounts	Require one declared gross, net or drained mass basis, separate vegetable and medium masses, and consistent use of that basis in every normalization.

validate_mass_balance	each batch and process	Require non-negative amounts and a documented mass-balance residual within the facility's declared acceptance criterion; investigate and disclose failures.

validate_reasoned_estimate	temporary unmetered energy row	Require declared equipment, operating hours, load-factor rationale, scenario bounds, temporary status and replacement trigger; fail publication if the estimate remains unreviewed.
