# Peaches, otherwise prepared or preserved

## 1. Scope and Applicability

This PCR applies to peach products that are prepared or preserved for sale and remain identifiable as a peach-based product at the facility gate. It covers route-specific operations from receipt of peaches or a declared peach intermediate through preparation, preservation, packing, and release of the finished product. Canned peaches are one covered route; they do not define the whole category.

The PCR excludes fresh peaches, solely frozen or dried peaches, sugar-preserved products, jams, jellies, marmalades, beverages, and mixed-fruit products when they belong to another product category. Agricultural production, manufacture of purchased ingredients and packaging, distribution, retail, consumer use, and end-of-life are outside the foreground boundary and are represented by linked upstream or downstream datasets when required by the study.

Each foreground data package shall describe one homogeneous preservation route and product specification. A canned heat-preservation route and another preservation route are mutually exclusive for one reference product dataset; facilities using both shall create separate route-specific datasets.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.meat-fish-fruits-vegetables-oils-and-fats.peaches-otherwise-prepared-or-preserved |
| classification_refs | CPC 3.0: 21492, Peaches, otherwise prepared or preserved |
| covered_products | Prepared or preserved peach products, including a declared canned-stone-fruit route and other declared preservation routes that remain within this semantic category |
| excluded_products | Fresh, solely frozen, solely dried, sugar-preserved, jam, jelly, marmalade, beverage, or mixed-fruit products classified elsewhere |
| representative_product | Route-specific prepared or preserved peach product in its marketable form |
| production_route | Exactly one of `canned_heat_preservation` or `other_declared_preservation`; the routes shall not be combined in one reference product dataset |
| market_state | Finished, preserved, and packed product at the producing facility gate |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provision of a route-specific prepared or preserved peach product in its declared marketable form |
| How much | 1 kg net peach product on the declared mass basis, excluding primary and secondary packaging mass |
| How well | Conforming to the producer's declared product specification; canned-route products additionally declare the applicable CXS 242-2003 form and packing medium |
| How long or cycle | One completed production batch or campaign through release at the producing facility gate; no storage duration or shelf-life service is implied |
| reference_flow_link | The functional unit is realized by the single Tiangong product flow and mass reference object below |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Peaches, otherwise prepared or preserved `91d82100-aaec-459c-b815-abd64025b71e` |
| 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 | preservation route; peach form or particle form; packing medium or formulation; total-net-content or drained-solids mass basis for products in liquid medium; primary packaging type; feedstock condition at receipt; production geography; reference period |

When constructing a foreground data package, the items listed in `Required qualifiers` must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass_basis` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Report net product mass excluding packaging. For product in a liquid medium, declare whether the reference amount is total net contents or drained peach solids; do not convert between these bases without paired measured values. |
| `batch_mass_consistency` | peach, ingredient, intermediate, product, co-product, and waste masses | Mass | kg | Preserve the recorded as-received or other declared moisture/state basis and use one consistent batch boundary before normalization to 1 kg reference product. |
| `energy_record_consistency` | electricity, steam, heat, and fuel inputs | Energy or fuel-specific property | recorded unit plus MJ or kWh when converted | Retain meter or invoice units, conversion factor, and conversion source; do not treat electricity, thermal energy, and fuel mass or volume as interchangeable. |
| `route_and_pack_separation` | route and packaging observations | Route and packaging descriptors | not applicable | Keep records separated by the declared preservation route, product form, packing medium or formulation, and primary package; allocate shared records only under section 7. |

## 5. System Boundary

The foreground boundary begins with peaches or a declared peach intermediate received at the processing facility and ends with the released prepared or preserved peach product at the producing facility gate. It includes directly controlled receiving, sorting, preparation, preservation, packing, finished-product handling, on-site utilities, wastes, wastewater, and direct emissions. Purchased peaches, ingredients, utilities, packaging, waste treatment, and transport outside direct control are linked as upstream or downstream datasets rather than silently omitted.

| --- | --- |
| declared_starting_condition | Peaches or a peach intermediate at facility receipt, with product state, supplier, origin, moisture or packing-medium condition where relevant, and measured received mass declared |
| starting_condition_role | Foreground entry condition and traceability anchor; agricultural cultivation or prior intermediate production remains upstream |
| product_classification_scope | Prepared or preserved peach products within the semantic scope corresponding to CPC 3.0 subclass 21492 |
| recursive_input_rule | Record a purchased prepared or preserved peach input in the same category as a separate product input and link its supplier dataset; do not expand it again inside the receiving foreground process |
| upstream_dataset_requirement | Link datasets for peaches or peach intermediates, recipe ingredients, processing aids, energy carriers, water supply, packaging, inbound transport when in scope, and treatment of exported waste or wastewater |
| disclosure | Declare starting product condition, selected exclusive preservation route, product form, packing medium or formulation, mass basis, primary package, facility geography, reference period, and all excluded or externally treated operations |

| `boundary_upstream_links` | purchased inputs and external treatment | Represent material purchased inputs, packaging, energy carriers, water supply, transport in scope, and external waste treatment with traceable upstream or downstream datasets. | `eu-pef-2021-2279` |
| `boundary_route_exclusivity` | preservation and packing | Instantiate exactly one declared preservation route for the reference product. Treat `canned_heat_preservation` as a covered route and not as the default for all products in the category. | `unsd-cpc-3-0-21492`; `codex-cxs-242-2003` |
| `boundary_exclusions` | downstream life cycle and products classified elsewhere | Keep distribution, retail, use, and end-of-life outside this facility-gate dataset, and do not use this PCR for the excluded product categories listed in section 1. | `unsd-cpc-3-0-21492`; `eu-pef-2021-2279` |

## 6. Process Inventory Structure

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |

| `validation_record_linkage` | collected and calculated values | Confirm every `collected_record` or `calculated_from_collection` row links to a declared protocol and reconciles to raw records on the same route, product specification, period, and mass basis. | `eu-pef-2021-2279` |
| `validation_allocation` | co-products and shared operations | Confirm subdivision was attempted first and every residual allocation or recovery claim states method, driver, values, reference period, assigned shares, and sensitivity. | `eu-pef-2021-2279` |
| `validation_source_scope` | use of external sources | Confirm CPC supports only the category reference, CXS 242-2003 is used only for the canned-stone-fruit route, and PEF guidance is not treated as product-specific quantitative evidence. | `unsd-cpc-3-0-21492`; `codex-cxs-242-2003`; `eu-pef-2021-2279` |
| `validation_estimate_replacement` | provisional screening envelopes | Confirm every `reasoned_estimate` is explicitly conditional, contains no invented source id or mandatory numeric value, and is replaced once its stated representative-record or source-evidence trigger is met. |  |
