Uncooked pasta, not stuffed or otherwise prepared

1. Scope and Applicability

This PCR covers factory production of uncooked, unfilled pasta and noodle products that are not otherwise prepared and fall within CPC 3.0 code 23710. Covered products may be dry, semi-dried, or another declared uncooked moisture state and may use wheat, rice, other cereals, pulses, or mixtures as the principal farinaceous material. The foreground data package shall describe the actual formulation, forming route, conditioning state, packaging state, and reporting gate.

Filled pasta, cooked or pre-cooked pasta, seasoned or otherwise prepared products, complete dishes, sauces, and products whose principal delivered function is not an uncooked pasta product are excluded. Ingredient production, consumer cooking, distribution, and end-of-life are not part of the default foreground manufacturing dataset, but may be connected as upstream or downstream datasets in a lifecycle model.

The Tiangong flow 540fef24-1038-48b8-8ee1-8cc415df780a is a verified product flow for semi-dried noodles and is used only as the representative product form for this category. It is not a generic UUID for every CPC 23710 product. A data author shall declare the actual product form and shall replace the representative UUID when a more specific real Tiangong flow matches that product. The representative UUID must never be silently assigned to dry pasta, fresh uncooked pasta, egg pasta, rice noodles, or another materially different form.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.grain-mill-products-starches-and-starch-products-other-food-products.uncooked-pasta-not-stuffed-or-otherwise-prepared
classification_refs	CPC 3.0: 23710 — Uncooked pasta, not stuffed or otherwise prepared
covered_products	Uncooked and unfilled pasta or noodles delivered without other preparation; dry, semi-dried, fresh-uncooked, or another explicitly declared moisture state; wheat-, rice-, other cereal-, pulse-, or mixed-material formulations
excluded_products	Filled pasta; cooked or pre-cooked pasta; seasoned or otherwise prepared pasta; complete dishes; sauces; couscous or another product classified outside CPC 23710
representative_product	Semi-dried noodles are the representative product/physical form because the verified Tiangong reference flow is specific to that form; the category remains broader than the representative flow
production_route	Ingredient receipt and preparation; dough or batter preparation; forming by extrusion, sheeting, cutting, or another declared method; product-specific conditioning or drying; inspection; and packaging or bulk release
market_state	Uncooked product at the declared factory-gate release condition, with moisture/conditioning and packaging state explicitly reported

3. Reference Flow

Field	Value
What	Uncooked, unfilled, and not otherwise prepared pasta or noodles at the declared factory-gate release condition
How much	1 kg net product mass, excluding packaging
How well	Conforming to the producer's release specification and applicable legal or customer requirements for the declared product form, formulation, moisture/conditioning state, and packaging state
How long or cycle	One production campaign or reporting period sufficient to represent the declared product until the factory-gate hand-off; shelf life is reported as metadata and does not change the 1 kg reference amount
reference_flow_link	One kilogram of the declared saleable uncooked pasta output; use the representative semi-dried-noodles UUID only when that identity is accurate, otherwise select a more specific real product flow

Field	Value
Reference amount	1 kg net uncooked pasta product
Reference product flow	semi-dried noodles 540fef24-1038-48b8-8ee1-8cc415df780a — representative only; replace for a more specific actual product form
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	actual product form and Tiangong product-flow identity; principal farinaceous material; formulation and egg/non-egg status; forming technology; moisture or conditioning state at release; packaging or bulk state; production geography and facility/route; factory-gate reporting point

When constructing a foreground data package, every item listed in Required qualifiers shall be declared in dataset metadata, process notes, the reference-flow comment, the product description, or an equivalent field. Missing qualifiers make the reference-flow definition incomplete. If the declared form is not semi-dried noodles, retaining UUID 540fef24-1038-48b8-8ee1-8cc415df780a without an explicit documented identity match is a validation error.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	Reference product and mass-normalized product/intermediate rows	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Report the reference product as net product mass. Packaging mass is inventoried separately and is never included in the 1 kg reference amount.
mass_conversion	Ingredient, intermediate, product, waste, and moisture-balance mass records	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Convert source records to kg using documented unit conversions before normalization; retain original units and conversion evidence.
conditioning_state	Product and intermediate mass values	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Record the measurement point and product moisture/conditioning state. Do not compare or combine masses measured at materially different conditioning states without a documented moisture correction.

Boundary Abstraction

Field	Value
declared_starting_condition	Accepted farinaceous ingredients, water, other formulation ingredients, utilities, and packaging materials at the manufacturing-site receipt point, together with the declared formulation, product form, and initial moisture state
starting_condition_role	Foreground manufacturing input gate; upstream production burdens are supplied by separate traceable datasets rather than recreated inside the pasta manufacturing process
product_classification_scope	CPC 3.0 code 23710 across declared uncooked and unfilled product forms; the semi-dried-noodles flow is representative, not category-wide identity authority
recursive_input_rule	Purchased uncooked pasta or noodle material from the same category that enters reprocessing shall be recorded once as a technosphere product input with its own upstream dataset and declared state; do not recursively reconstruct its manufacturing inside this foreground dataset
upstream_dataset_requirement	Each material ingredient, utility, and packaging input shall link to a geographically, technologically, and temporally representative upstream dataset or be disclosed as a data gap
disclosure	Declare product form, formulation, moisture/conditioning state, forming and conditioning technologies, packaging state, reporting gate, included sites, allocation method, data period, and any omitted or unresolved flows

rule_id	Applies to	Rule	source_ids
boundary_foreground_manufacturing	All foreground datasets	Include ingredient receipt/preparation, dough or batter preparation, forming, product-specific conditioning, inspection/rework accounting, and packaging or bulk release when performed within the reporting organization.	unafpa-dry-pasta-pefcr-2020
boundary_dry_route	Dry or semi-dried routes	Include the actual conditioning/drying operation, electricity, thermal energy or fuel, water or moisture removal, losses, and the declared released moisture state. Apply dry-pasta source rules only to a route that is demonstrably within their dry-pasta scope.	unafpa-dry-pasta-pefcr-2020
boundary_upstream_connections	Ingredient, utility, and packaging production	Represent upstream production and inbound services through separate datasets linked to the collected foreground bill of materials; do not treat an unverified generic proxy as product-specific data.	unafpa-dry-pasta-pefcr-2020
boundary_downstream_exclusion	Default foreground product dataset	Exclude distribution, consumer storage/cooking, packaging end-of-life, and food end-of-life from this factory-gate foreground dataset. Add them only in an explicitly declared downstream lifecycle model.
boundary_recursive_category_input	Same-category purchased pasta or noodle input	Record the purchased product at its actual entry state with a distinct upstream dataset and do not expand the same category recursively within the foreground process.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	Reference product and all product-specific rows	Required qualifiers shall be complete and internally consistent. The semi-dried-noodles UUID may remain only for an actual identity match; otherwise a more specific verified flow shall replace it.	Product master, release specification, CPC check, and full Tiangong flow readback
dq_temporal_representativeness	Foreground activity data	Use one consistent reporting period. An annual dry-pasta dataset shall cover 12 consecutive months; another product form may use a representative campaign or seasonal period only with justification and production-volume coverage disclosure.	Dated meter, batch, production, inventory, and waste records; coverage calculation; justification
dq_measurement_traceability	Mass, moisture, water, electricity, and thermal-energy records	Preserve original readings, units, meter/scale identity, calibration or verification status, conversions, and responsible record source.	Calibration certificates, meter logs, laboratory method records, invoices, and conversion worksheet
dq_mass_balance	Both foreground processes	Reconcile material inputs with intermediate/product outputs, measured waste, moisture release where relevant, inventory change, and documented internal return. Investigate and disclose unexplained imbalance; do not force closure with an undocumented default.	Campaign mass-balance worksheet and variance investigation
dq_completeness	Foreground inventory	Include all material ingredient, water, energy, packaging, product, and waste flows that cross the declared foreground boundary. Record not-applicable decisions and unresolved UUIDs explicitly.	Completeness checklist tied to process map, BoM, utilities, waste register, and packaging records

validate_representative_flow_use	Reference product flow	Confirm actual product form against the full Tiangong flow record. If the product is not semi-dried noodles or a more specific matching real flow exists, UUID 540fef24-1038-48b8-8ee1-8cc415df780a shall be replaced; silent reuse is an error.
validate_reference_support_chain	Reference amount and unit	Confirm reference amount 1 kg net product, Mass UUID 93a60a56-a3c8-11da-a746-0800200b9a66, Units of mass UUID 93a60a57-a4c8-11da-a746-0800200c9a66, and reference unit kg; packaging mass shall remain separate.
validate_process_coverage	Foreground process map	Confirm that actual formulation, forming, conditioning/drying, inspection/rework accounting, and packaging or bulk release are represented and that non-applicable route steps are explicitly justified.	unafpa-dry-pasta-pefcr-2020
validate_inventory_and_mass_balance	Foreground inventory	Confirm collected ingredient/packaging BoM, energy, water, output, loss, and waste records; reconcile mass by process and product state without undocumented default values.	unafpa-dry-pasta-pefcr-2020
validate_allocation	Shared operations and multi-output processes	Confirm subdivision was attempted first and any remaining allocation has a physically representative driver, complete denominator, same-period records, and disclosure.	unafpa-dry-pasta-pefcr-2020
validate_period_and_traceability	Dataset quality	Confirm period alignment, site/line scope, calibration/conversion evidence, source traceability, upstream dataset linkage, and explicit data gaps.	unafpa-dry-pasta-pefcr-2020

10. Published Dataset Profile

Field	Value
dataset_role	Foreground product-production dataset for one declared uncooked pasta form and factory-gate release condition
downstream_use	May be published as a secondary_dataset or background_dataset after methodology review, UUID completion, validation, and release controls
allowed_use	Product systems whose product form, formulation, forming/conditioning route, moisture state, packaging state, geography, technology, and reporting gate are compatible with the declared dataset
excluded_use	Silent use of the semi-dried-noodles UUID for another product form; cooked, filled, seasoned/prepared, or complete-dish products; use as a cradle-to-grave result without explicit downstream stages; unsupported cross-form or cross-route averages
required_metadata	Canonical PCR id; CPC; actual Tiangong product-flow UUID; all required qualifiers; site/geography; technology and process map; reporting period and gate; net product and packaging basis; allocation; source and proxy disclosures; unresolved-flow status
required_quality_disclosure	Record coverage, calibration/conversion evidence, mass-balance result, allocation rationale, temporal/geographic/technological representativeness, dry-pasta-source applicability, missing UUIDs, proxy datasets, and validation findings
update_trigger	Change in product form or flow identity, formulation, egg status, principal material, forming or conditioning technology, released moisture state, packaging configuration, site/energy supply, allocation basis, reporting gate, material supplier mix, legal specification, or evidence source
