Abstract

This study compared the concentration of vitamin C (ascorbic acid, AA, and dehydroascorbic acid, DHA) and carotenoids (lycopene and β-carotene) between three fruits produced by organic and conventional farming. Vitamin C and carotenoids were analysed by high-performance liquid chromatography. The Student t-test (α=5%) was applied to determine differences between the organic and conventional production systems. AA content was significantly higher in organic acerola (4023.39mg/100g) compared to its conventional production (2294.53mg/100g). Conversely, AA content was significantly higher in conventional strawberries (42.45mg/100g) than the organic ones (30.74mg/100g). The conventional production also showed significantly higher contents of DHA (persimmon: 7.50mg/100g vs. 0.96mg/100g) and β-carotene (acerola: 6130.24μg/100g vs. 2486.38μg/100g) than the organic fruits. Lycopene was only detected in persimmons, but no significant difference was observed between farming systems. There was no evidence of the nutritional superiority of the organically grown fruits.

  • The vitamin C content of individual plant species is highly variable due to factors including place of cultivation, harvesting time, weather conditions, latitude, genotype, agrotechnology, analytical method, and processing.

    “As can be seen from Table 1, the vitamin C content of individual plant species is highly variable due to many factors, including place of cultivation, harvesting time (ripening stage), weather conditions, latitude, genotype, agrotechnology, analytical method used for determination, and processing [24,32,33,34,35].”

    From Vitamin C-Sources, Physiological Role, Kinetics, Deficiency, Use, Toxicity, and Determination (2021) · cites this paper as [34]

    Section 3.3 reports that vitamin C varies with cultivation factors, including soil fertility, nutrient availability and irrigation; Section 3.5 finds differences among the fruits and production systems studied. The paper does not establish the full attributed list of causes, particularly latitude, weather, harvest timing, analytical method and processing. The study held geographic region and climatic conditions constant (Section 2.2). (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
