# Grapefruit juice

## 1. Scope and Applicability

This PCR supports foreground data packages for unfermented grapefruit juice intended for direct consumption at the processing-site gate. It covers directly expressed (not-from-concentrate) juice, juice made from grapefruit concentrate, and combinations of those routes when the route shares are declared. The foreground boundary may include fresh-fruit receipt, sorting, washing, citrus-oil recovery, mechanical extraction, screening or finishing, clarification, blending or reconstitution, preservation, cooling, filling, primary packaging, cleaning-in-place, and on-site wastewater handling when these operations are controlled by the reporting site.

Grapefruit concentrate as a product sold in its concentrated state, grapefruit nectar, multi-fruit juice, grapefruit-flavoured drinks, fermented beverages, and fresh grapefruit are outside the product scope. Distribution, retail, consumer refrigeration or preparation, and packaging end-of-life are outside the factory-gate foreground boundary unless a study explicitly extends it. Applicable food-law and market specifications prevail when they are stricter than the identity and quality checks stated here.

| --- | --- |
| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.meat-fish-fruits-vegetables-oils-and-fats.grapefruit-juice |
| classification_refs | CPC 3.0: 21432 (Grapefruit juice; exact mapping context) |
| covered_products | Unfermented single-strength grapefruit juice; not-from-concentrate grapefruit juice; grapefruit juice from concentrate; declared blends of directly expressed and reconstituted grapefruit juice |
| excluded_products | Grapefruit juice concentrate sold as concentrate; grapefruit nectar; multi-fruit juices; flavoured or diluted juice drinks that do not meet the declared grapefruit-juice identity; fermented grapefruit beverages; fresh grapefruit |
| representative_product | Unfermented single-strength grapefruit juice released at the processing-site gate |
| production_route | Fresh grapefruit receipt, preparation, mechanical juice extraction and finishing, with optional concentration steps under the same foreground control; and/or receipt of grapefruit concentrate followed by reconstitution and blending; then preservation, cooling, and factory-gate preparation |
| market_state | Finished liquid in a declared bulk, aseptic, chilled, frozen, canned, or other primary-packaged state at the processing-site gate |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Finished, unfermented grapefruit juice intended for direct consumption |
| How much | 1 kg net mass of grapefruit juice, excluding primary and secondary packaging |
| How well | Meets the declared route-specific grapefruit-juice identity, composition, preservation, and market requirements; reconstituted juice meets at least 10.0 degrees Brix at 20 degrees C under the Codex baseline unless a stricter applicable requirement is declared |
| How long or cycle | One production lot at factory-gate release; shelf life is a required qualifier but is not the normalization basis |
| reference_flow_link | `grapefruit_juice_reference_output` |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Grapefruit juice `796385da-cb79-4275-8087-13bc9656ff65` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |

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 |

| `route_mass_conversion` | all route inputs and outputs | Mass | kg | Preserve measured lot masses and moisture or concentration state. Convert volume records to mass only with a batch- or product-specific density and retain the density value, temperature, method, and source record. |
| `soluble_solids_check` | reconstituted grapefruit juice | Soluble solids by refractometry | degrees Brix at 20 degrees C | Record the corrected soluble-solids result and method. Under the Codex baseline, reconstituted grapefruit juice must be at least 10.0 degrees Brix; apply and cite a stricter market rule when relevant. |

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_avoid` | juice, grapefruit oil, usable citrus solids, and other co-products | First avoid allocation by subdividing independently measured operations or by expanding the system when the additional functions and substituted products are robustly demonstrated. | `ec-pef-method-2021` |
| `allocation_physical` | inseparable multifunctional operations | If subdivision or system expansion is not practicable, use a documented, quantifiable physical relationship that reflects how inputs and outputs provide the functions; do not default to mass merely because masses are available. | `ec-pef-method-2021` |
| `allocation_other_relationship` | multifunctional operations lacking a defensible physical relationship | Use another relationship, such as site- and period-specific economic value, only after documenting why subdivision, system expansion, and physical allocation were rejected; disclose prices, period, currency, factors, and sensitivity. | `ec-pef-method-2021` |
| `allocation_waste_status` | peel, pulp, seeds, rejected fruit, off-specification juice, and sludge | Classify each output as product, co-product, or waste from its documented destination and function. Waste treatment remains in the generating system; do not assign avoided-production credits without a separately justified system-expansion model. | `ec-pef-method-2021` |
| `allocation_shared_site_services` | utilities and site services shared with other products | Prefer sub-metering. Otherwise allocate only the residual shared amount using a causal driver such as process time, metered throughput, cleaning cycle, or equipment demand, and retain the calculation. | `ec-pef-method-2021` |
