Vegetable juice

Completeness scorecard

Deterministic gap audit — no score is composite, no cell is LLM-judged. Each chip is re-derivable by re-running tools/evidence/build-ingredient-scorecard.mjs. review: residuals and missing data are worked autonomously via data/evidence/ingredient-scorecard-review-flags.csv and wiki/completeness-gaps.md.

This is a structural ingredient node created so product pages can link to a real wiki target. Occurrence values remain pending until a source is promoted for this ingredient.

Heavy metal contamination profile

Per-analyte snapshot derived from the machine-readable contamination_profile in the frontmatter above. data gap indicates the literature has been reviewed for this commodity-analyte combination and no usable occurrence data was found (a finding, not a placeholder).

Why this commodity accumulates heavy metals

Vegetable juice is the liquid extracted or processed from vegetables (tomato juice, carrot juice, beet juice, celery juice, and mixed-vegetable products like V8). Vegetable juice carries the source-vegetable heavy-metal profile, concentrated per-mass via water-content removal during juicing or evaporation. Different vegetable types contribute different baseline metal profiles: tomato juice carries source-tomato Cd; carrot juice carries source-carrot Pb and Cd at moderate concentrations; beet juice can carry higher Pb because beet (Beta vulgaris) is a moderate Pb accumulator; leafy-vegetable juice (kale, spinach, parsley juices in cold-pressed and craft-juice formulations) carries the leafy-greens Cd and Pb at concentrated per-mass levels. The HMTc panel concerns for vegetable juice are Pb and Cd (dominant), iAs in juice from vegetables grown in As-affected regions, and Sn for canned vegetable juices including canned tomato juice.

Ranges by source, region, and variety

Variance within vegetable juice tracks vegetable type (tomato vs leafy-green vs root-vegetable juice carry different baseline profiles), source-vegetable origin region (industrial-region production, urban-garden production, atmospheric-deposition-affected production drive higher loads), processing scale (commodity scale vs cold-pressed craft juicing), and packaging (canned vs glass-bottle vs aseptic carton vs PET). Cold-pressed leafy-green juices marketed for health-and-wellness consumption can carry per-mass Pb and Cd at concentrated levels because the cold-pressing efficiently extracts the per-mass leafy-green metal load with minimal dilution.

Processing effects

Vegetable-juice manufacturing varies by product: tomato juice is typically pressed from cooked tomato; carrot and beet juice are pressed from raw or lightly-blanched vegetables; cold-pressed juice extracts the per-vegetable juice content without thermal processing. Each method partitions metals between juice and solid fractions differently. Cold-pressed juicing typically retains more of the source-vegetable metal load in the juice phase because the pressing is less aggressive than thermal-and-pressed extraction. Canned vegetable juice (canned tomato juice, V8, canned mixed-vegetable juices) introduces a Sn migration pathway. Pasteurization does not affect metals.

Ingredient-derivative risk

Vegetable juice routes into the vegetable-juices-non-root and vegetable-juices-root-vegetable-containing product rows. Derivatives include canned tomato juice, V8 and similar mixed-vegetable juices, fresh-pressed cold-pressed juice products, and vegetable-juice concentrates (further concentration of per-mass metals). Vegetable-juice powders (used in flavoring and seasoning applications) concentrate per-mass metals via dehydration.

Mitigation options

Sourcing levers (supply-chain-screening) include source-vegetable origin specification (avoidance of industrial-region or atmospheric-deposition-affected production); supplier-soil verification for vegetable suppliers; and contractual specification of Pb/Cd ceiling on incoming vegetable supply.

Agronomic levers (agronomic) operate at the source-vegetable cultivation stage; see vegetables, leafy-greens, and per-vegetable ingredient pages for the upstream interventions.

Processing levers (processing) include processing-equipment material specification; pressing-residue handling (the solid residue concentrates source-vegetable metals and should not be returned to the juice stream); and washing optimization to maximize surface-Pb removal pre-juicing.

Formulation levers (formulation) include mixed-vegetable formulations that dilute single-vegetable metal loads; substitution of higher-risk vegetables (leafy greens, beets) with lower-risk vegetables (tomatoes, citrus) where the matrix permits.

Testing and QC levers (testing-and-qc) include lot-level Pb, Cd, iAs testing on finished vegetable juice. ICP-MS is the standard analytical platform.

Packaging and storage levers (packaging-and-storage) include can-lining specification for canned vegetable juice; aseptic carton, glass, or PET eliminates Sn migration.

Regulatory limits that apply

• eu-2023-915 — EU Reg. 2023/915 sets maximum levels for Pb and Cd in processed vegetables including vegetable juice as a processed-vegetable derivative.
• FDA does not currently set a quantitative action level specific to vegetable juice; general FDA enforcement on toxic-element contamination applies.
• Codex Alimentarius CXS 247-2005 (General Standard for Fruit Juices and Nectars) includes provisions that have been extended to vegetable juices in some interpretive contexts.
• California Prop 65 (california-prop65) Pb MADL applies to vegetable-juice products sold in California.
• EU Sn-in-canned-food regulation sets 100 mg/kg maximum level for canned beverages including canned vegetable juice.
