Alzagtat et al. 2016 - Conformity of Fruit Nectar Samples to Libyan Specification Standards

This study evaluated Libyan fruit nectar samples against Libyan specification standards and measured heavy metals in local and imported nectars, including pineapple-containing nectar categories.

Key numbers

Source units are mg/kg.

• Local fruit nectars: Fe 4.45-7.30; Zn 1.77-4.01; Cu 1.56-3.23; total arsenic 0.02-0.07; Pb 0.002-0.008; Cd 0.002-0.008.
• Imported fruit nectars: Fe 3.56-9.02; Zn 1.85-4.05; Cu 1.75-4.54; total arsenic 0.01-0.18; Pb 0.002-0.006; Cd 0.002-0.008.
• Imported samples identified in the text as produced by m, n, and m had arsenic values 0.18, 0.15, and 0.16 mg/kg (pineapple sample 6 by m, mixed-fruit sample 12 by n, guava sample 13 by m).

Methods

The paper reports heavy-metal measurements for local and imported fruit nectars; arsenic is reported as total arsenic. The source text also includes broader nectar quality measures such as TSS, acidity, sugars, and vitamin C.

Implications

This source can support fruit-nectar and pineapple-nectar context, especially for total arsenic in imported nectars. It is a summary-level source rather than a sample-level dataset.

Verification notes

• Source identity checked against DOI 10.24925/turjaf.v4i7.524-530.533 and the downloaded PDF.
• The PDF extraction uses “Ar” in places for arsenic; this page records it as total arsenic because no speciation is reported.
• The paper distinguishes nectars (25–50% natural juice content) from juices (>50%) per Codex Alimentarius 247-2005. The taxonomy snapshot has no fruit-nectar product slug; routing therefore falls back to [[products/fruit-juice-not-canned]] and [[ingredients/fruit-juice]]. Proposed slug gap: a fruit-nectars-not-canned (or equivalent) product/ingredient pair for nectar-specific occurrence data.
• The paper measures six nectar varieties (grape, pineapple, guava, orange, apple, mixed-fruit). The matrices field is intentionally kept at the broad fruit-nectar umbrella per Part 5b routing discipline rather than pre-specifying per-fruit nectar matrices that the taxonomy does not provide.
