Other vegetables and pulses, frozen

1. Scope and Applicability

This PCR covers factory-gate foreground data production for plain frozen vegetables and pulses whose route includes receipt, selection, cleaning, product-specific preparation, quick freezing, packaging, and frozen storage before dispatch. Blanching, cutting, cooling, glazing, and individual-quick-freezing or block-freezing are included only when used by the declared product route.

The Tiangong reference flow Quick-frozen vegetables is a representative flow for this category, not a claim that all vegetables and pulses share one recipe, yield, energy demand, or storage profile. Each data package shall represent one declared product or a documented production mix and shall identify species/cultivar or pulse type, incoming condition, cut form, blanching treatment, freezing format, additives or glazing, package format, geography, production period, and frozen-storage duration. Product-specific primary records replace all provisional screening ranges.

Excluded are potatoes, fruits, mushrooms when classified elsewhere, canned or dried products, purees and juices, seasoned or sauced preparations, complete meals, retail and distribution after factory dispatch, and consumer thawing or cooking. Agricultural production and inbound transport are upstream linked datasets rather than foreground factory operations.

validation_scope_qualifiers	Product identity	Reject an unspecified generic recipe: all required qualifiers and any production-mix shares shall be present and internally consistent.	codex-cxs-320-2015
validation_process_coverage	Foreground boundary	Confirm both required processes and every route-applicable conditional operation, utility, reject, wastewater, package, storage interval, and treatment destination are represented.	codex-cxp-8-1976
validation_mass_balance	Material inventory	Confirm internal transfers match, net output equals the quantitative reference, and material/water balance gaps are disclosed and investigated.	mass-balance-identity
validation_temperature	Frozen condition	Confirm batch-linked freezing endpoint, storage, and dispatch records demonstrate the declared -18 °C-or-colder condition and identify excursions.	codex-cxp-8-1976; eu-directive-89-108-eec; eu-regulation-37-2005
validation_no_double_counting	Internal and upstream flows	Confirm internal prepared-product transfers carry no duplicate upstream burden and same-category purchased inputs use one matching upstream dataset.	mass-balance-identity
validation_refrigerant	Direct emissions	Confirm chemical-specific facility reconciliation, equipment scope, recovery, stock change, product allocation, and no unsupported zero-emission assumption.	ipcc-2006-v3-ch7
validation_provisional_evidence	Candidate ranges	Confirm reasoned-estimate ranges are labelled provisional and have not replaced foreground records or been presented as universal category parameters.
validation_allocation	Multi-output and shared systems	Confirm subdivision was attempted first and every remaining allocation method, driver, period, share, and sensitivity is disclosed.	iso-14044-2006

10. Published Dataset Profile

Field	Value
dataset_role	Product- and route-specific foreground factory data package for frozen vegetables or pulses
downstream_use	secondary_dataset; background_dataset after review and publication
allowed_use	LCA process or lifecyclemodel construction when product, geography, technology, production period, package, and storage qualifiers match the study
excluded_use	A universal recipe for all frozen vegetables/pulses; agricultural production; downstream distribution/retail/use without added datasets; products outside scope; use of provisional ranges as reviewed defaults
required_metadata	PCR id and version used; actual product/type; mix shares; supplier/origin; site/geography; production period; incoming state; preparation/blanching/freezing route; glazing/additives; package; storage duration; dispatch temperature; allocation; upstream dataset references
required_quality_disclosure	Temporal/site coverage; mass and water balance; meter and sensor coverage; missing data; allocation and sensitivity; refrigerant method; temperature excursions; provisional estimates; exclusions and uncertainty
update_trigger	Change in product mix, supplier/origin, yield, pretreatment, freezing technology, package, refrigerant, energy source, cold-store duration, site, regulation, or evidence that materially changes the normalized inventory
