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.

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 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
Reference unit	kg
Required qualifiers	route share (not-from-concentrate and/or from-concentrate); fruit species and product identity; measured soluble-solids result and method; preservation method; bulk or primary-package state and packaging material; pulp or clarification state; added sweetener and other optional ingredient status; production geography and period; shelf-life or storage condition; co-product and waste treatment; allocation method

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_net_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Normalize all foreground amounts to 1 kg net grapefruit juice at factory-gate release; exclude packaging mass from the reference amount and record packaging separately.
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
