1. Scope and Applicability
This PCR specifies foreground data production for unseasoned quick-frozen peas made from young, tender peas of Pisum sativum L. It covers receipt of fresh peas, shelling when required, cleaning, sorting, washing, blanching, cooling and draining, quick freezing, inspection, packaging, and on-site frozen storage up to release at the factory cold-store gate. It is suitable for bulk or retail-packed, sized or unsized, individually quick-frozen or block-frozen peas when the presentation is declared.
Agricultural cultivation, harvested-pea transport to the factory, manufacture of purchased energy, water, packaging and refrigerants, outbound distribution, retail, cooking, consumption, and end-of-life are outside the foreground boundary. Those stages require linked upstream or downstream datasets when a complete life-cycle model is constructed. Peas canned, dried, fresh, mixed with other foods, seasoned, sauced, or otherwise preserved but not frozen are outside this category.

|---|---|---|---|---|
reference_mass | Reference frozen-pea output | Mass 93a60a56-a3c8-11da-a746-0800200b9a66 | kg | Normalize the foreground inventory to exactly 1 kg net frozen peas at factory cold-store release; exclude primary, secondary and tertiary packaging mass. |
wet_mass_release_basis | Fresh, intermediate and final pea masses | Mass | kg | Use as-weighed wet mass at the recorded process point. Record tare correction, scale identity and measurement time; do not convert to dry matter unless a separately disclosed calculation is required. |

7. Allocation and Co-product Handling
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
allocation_avoid | Shared processes and utilities | Avoid allocation by subdividing processes and using process meters, lot masses, operating time, occupied cold-store volume and storage duration. System expansion may be used only when the additional function and substituted system are demonstrated and reported. | eu-pef-2021-2279 |
allocation_internal_rework | Peas reworked within the same production system | Treat internal rework as an internal transfer. Retain its mass in the lot balance and assign no avoided-product credit. | eu-pef-2021-2279 |
allocation_residue_status | Pods, rejected peas and other organic residues | Classify residues as waste unless a stable intended product function and market are documented. If they are co-products, first apply a relevant quantifiable physical relationship; use another relationship such as economic value only when physical allocation is not defensible, and disclose prices, period and sensitivity. | eu-pef-2021-2279; eu-jrc-fdm-bref-2019 |
