# Food Chemistry (food-chemistry)

## Journal positioning

Food Chemistry is the Elsevier journal for the chemistry and biochemistry of foods —
composition, bioactive and functional compounds, food analysis and authentication, the
chemistry of processing and storage, and food safety and contaminants. Its defining
expectation is **rigorous analytical chemistry that yields chemical insight**: a
quantified compositional or mechanistic result obtained with properly validated methods,
adequate controls, and defensible quantification. A descriptive screening study with
poorly validated methods, no quantification, or no chemical-mechanism interpretation is a
weak fit, however topical the food matrix. This skill is a **fit / venue-selection /
re-framing** tool. It does not replace the journal's current author guidelines. Before
submitting, re-check the live Food Chemistry submission guidance.

## When to trigger

- The author names Food Chemistry and wants a fit/framing check for a food-chemistry paper.
- A compositional, bioactive-compound, or food-analysis result must be re-framed around its
  chemical mechanism or analytical advance rather than a single product survey.
- The author is choosing between Food Chemistry, a food-technology venue, and an
  analytical-chemistry journal.
- The author needs Food Chemistry's method-validation bar and its desk-reject heuristics.

## Scope & topic fit

- Food composition and structure: macro/micronutrients, lipids, proteins, carbohydrates,
  phytochemicals, and their changes during processing and storage.
- Bioactive and functional compounds: identification, quantification, bioaccessibility, and
  structure–activity relationships, with chemistry (not only an in-vitro assay) at the core.
- Food analysis and authentication: chromatography, mass spectrometry, spectroscopy,
  metabolomics/foodomics, and chemometric or fingerprinting methods for origin/adulteration.
- Chemistry of processing and reactions: Maillard, oxidation, enzymatic and fermentation
  chemistry, and the formation or loss of flavor, color, and nutrient compounds.
- Food safety chemistry: contaminants, residues, mycotoxins, process-induced toxicants, and
  their detection, fate, and mitigation with quantitative chemical evidence.
- Flavor, color, and sensory-linked chemistry when tied to identified compounds and concentrations.

## Method & evidence bar

- Analytical methods must be **validated and reported**: linearity, LOD/LOQ, recovery,
  precision, and matrix effects appropriate to the technique; instrument conditions stated.
- Quantification is expected — peak areas, "relative abundance," or untargeted detection
  without calibration and concentrations rarely suffices for a compositional claim.
- Compound identification must meet accepted confidence criteria (e.g., authentic standards,
  accurate mass, MS/MS fragmentation, retention behavior), not name-by-library-hit alone.
- Adequate controls and replication: blanks, matrix-matched standards, biological/analytical
  replicates, and statistics suited to the design (not pseudoreplicated single batches).
- Chemometric and authentication models need validation on independent samples and
  protection against overfitting; report cross-validation and class sizes.
- Mechanistic or structure–activity claims must be supported by direct chemical evidence,
  not inferred solely from a correlation between a crude extract and a bioassay.

## Structure & house style

- Standard research-article format (introduction, materials and methods, results and
  discussion, conclusion); re-check current article types and length on the live guide.
- Introduction must state the chemical/analytical gap and why this food matrix or compound
  class matters chemically, not merely that the product is popular or healthy.
- Methods must be reproducible: reagents, instrument parameters, calibration, and validation
  data sufficient for another lab to repeat the analysis.
- Figures carry the analytical evidence — annotated chromatograms/spectra, calibration and
  recovery data, and dose/structure relationships; raw identification support belongs in SI.
- Graphical abstract and highlights are expected; re-check current specifications on the live guide.

## Official-submission checklist

- Before giving submission-ready advice, read `../../resources/source-basis.md` and
  `../../resources/official-source-map.md`; start from the Elsevier anchors, then cite the
  current Food Chemistry page you checked.
- Search the live site for "Food Chemistry guide for authors" and follow the current Elsevier version.
- Re-check article types (research, review, short communication), length, and the graphical-abstract/highlights requirements.
- Confirm method-validation reporting expectations and any compound-identification confidence criteria.
- Re-check data-availability, raw-spectra/chromatogram deposition, and supplementary-data policy.
- Re-check competing-interests, funding, author-contribution, and AI-use disclosure, and open-access terms.
- If the live official instructions conflict with this skill, the official instructions win.

## Pre-submission self-check

- [ ] Analytical methods are validated (linearity, LOD/LOQ, recovery, precision) and the data are reported.
- [ ] Quantitative concentrations — not just detection or relative abundance — support the compositional claim.
- [ ] Compound identifications meet accepted confidence criteria, not library hits alone.
- [ ] Controls, blanks, and genuine replication are present, with statistics matched to the design.
- [ ] Any mechanism or structure–activity claim rests on direct chemical evidence.
- [ ] Highlights, graphical abstract, and reproducible methods are prepared per the live guide.

## Common desk-reject triggers

- Descriptive screening of a product with no quantification and no validated method.
- Compound identifications by library match alone, without standards or MS/MS confirmation.
- Bioactivity claims from a crude extract and one assay, with no chemistry or dose response.
- Untargeted "fingerprinting" or chemometric models with no independent validation (overfit).
- Process or composition study run on a single batch presented as a general result.
- Scope mismatch: a food-engineering, sensory-only, or formulation paper with no food-chemistry advance.

## Re-routing decision

- Review/critical synthesis rather than primary data → `trends-in-food-science-and-technology`.
- Food-systems significance beyond the chemistry → `nature-food`.
- Contaminant fate/transport and environmental impact emphasis → `environmental-pollution`.
- Exposure-to-health, dietary-contaminant epidemiology framing → `environment-international`.
- Pure analytical-method development for general matrices → an analytical-chemistry venue (e.g., `analytical-chemistry`).
