# Fruits and nuts, uncooked or cooked, frozen

## 1. Scope and Applicability

This PCR covers factory-gate production of uncooked or cooked fruits and nuts preserved by freezing and supplied as a frozen food or ingredient. It covers single-species products and declared mixtures, with or without declared sweeteners or other ingredients, when the product identity remains frozen fruit or frozen nuts. The foreground starts with receipt of identified fruit or nut raw material and includes preparation, conditional cooking or blanching, freezing, conditional packaging, and on-site frozen storage up to dispatch from the producing facility.

The PCR does not cover fresh, dried, canned, fermented, juiced, pureed, pasted, jammed, provisionally preserved, roasted, salted, or otherwise prepared products whose primary market identity is not frozen fruit or frozen nuts. Agricultural production, inbound transport, downstream distribution, retail, consumer thawing or cooking, and end of life are outside the foreground process boundary but shall be represented by appropriate upstream or downstream datasets when the study boundary includes them.

The selected Tiangong product flow is named **Banana**. UUID `ce6b2d04-9b60-4b60-a4e7-553d7ae67ce0` is a narrow representative identity for a frozen-banana case only. It shall not be treated as the product-flow identity for every fruit or nut in this PCR. A dataset for any other species, mixture, or materially different banana product shall replace this product flow with an appropriate reviewed Tiangong flow or undergo manual identity review before publication.

Codex product standards cited here are applied only to the products expressly covered by each standard. CXS 52-1981 applies to the specified quick-frozen strawberries and CXS 69-1981 to the specified quick-frozen raspberries. CXS 320-2015 is a standard for quick-frozen vegetables and supplies no category-wide requirement for the fruits and nuts covered by this PCR.

## 2. Product Category Identity

| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.meat-fish-fruits-vegetables-oils-and-fats.fruits-and-nuts-uncooked-or-cooked-frozen |
| classification_refs | CPC 3.0: 21493 - Fruits and nuts, uncooked or cooked, frozen |
| covered_products | Uncooked or cooked frozen fruits; uncooked or cooked frozen nuts; declared mixtures whose primary identity remains frozen fruit or frozen nuts; quick-frozen products only where the declared product and process meet the applicable product-specific standard |
| excluded_products | Fresh, dried, canned, fermented, juiced, pureed, pasted, jammed, provisionally preserved, roasted, salted, or otherwise prepared products outside the frozen-fruit-or-nut identity; frozen vegetables; products intended to be represented by a different principal food category |
| representative_product | Frozen banana for the supplied Tiangong product-flow UUID only; this representative is narrower than the category and is not a default identity for other species |
| production_route | Receipt and preparation of identified fruit or nut material; conditional cooking or blanching; freezing; conditional packaging; on-site frozen storage and factory-gate dispatch |
| market_state | Frozen product at factory gate, with species, composition, presentation, thermal condition, packaging condition, and intended market use declared |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Supply an identified edible fruit or nut product in its declared frozen, uncooked or cooked condition at the producing-facility gate |
| How much | 1 kg net frozen product, excluding transport and sales packaging |
| How well | Conforming to the declared species or mixture, ingredient composition, preparation and cooking state, presentation, freezing process claim, release temperature specification, and applicable product-specific quality standard |
| How long or cycle | One production batch through factory-gate release; on-site frozen-storage duration and any declared shelf-life information shall be reported rather than assumed |
| reference_flow_link | The reference flow is the net mass of conforming frozen product needed to deliver the declared 1 kg unit |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg net frozen product |
| Reference product flow | Banana `ce6b2d04-9b60-4b60-a4e7-553d7ae67ce0` |
| 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, every item 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. The Banana UUID is usable without replacement only when the represented product is frozen banana and all other qualifiers match the dataset.

Do not convert to dry matter unless both the measured moisture basis and conversion are disclosed. |

The -18 °C thermal-centre completion criterion from CXS 52-1981 and CXS 69-1981 is mandatory only for products claiming conformity to the respective strawberry or raspberry standard; it is not a default for banana or other products. |

| `validate_reference_mass` | Reference flow | Confirm that the quantitative reference is exactly 1 kg net conforming frozen product using Mass `93a60a56-a3c8-11da-a746-0800200b9a66`, Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66`, and kg, with packaging excluded. | `eu-pef-2021-2279` |

| `validate_temperature_claim` | Quick-frozen strawberry or raspberry conformity claim | For a CXS 52-1981 strawberry or CXS 69-1981 raspberry claim, verify recorded thermal-centre temperature reached -18 °C after thermal stabilization and that handling, packaging, and product scope match the cited standard. Do not run this criterion for banana, nuts, or other non-covered products. | `codex-cxs-52-1981`; `codex-cxs-69-1981` |
| `validate_mass_reconciliation` | Material-transforming processes | Confirm measured inputs and outputs are reconciled and that rejects, residues, co-products, wastewater solids where measured, samples, and losses are not hidden in product yield. Investigate and disclose unexplained imbalance. |  |
