Studies have shown that the consumption of apples has a beneficial effect on cardiovascular diseases and some cancers, largely as a result of their micronutrient and phytoconstituent contents. Apple peel not only contains more polyphenols than the flesh, but also is likely to contain pesticide residues. The present study aimed to compare the contents of certain micronutrients and residual pesticide levels in peeled and unpeeled apples.
Peeled apples contained fewer pesticide residues at lower concentrations than unpeeled apples. However, whether samples were peeled or not, the exposure values for pesticide residues in apples never exceeded the acceptable daily intake (ADI), but ranged between 0.04% and 2.10% of the ADI in adults for food intake estimated at the 95th percentile (277 g per person per day). Determination of polyphenol, fibre, magnesium and vitamin C levels showed that the nutritional differences observed between peeled and unpeeled apples were marginal.
The consumption of apples, such as the apples tested in the present study, results in an exposure to pesticides that is low for unpeeled apples, and lower for peeled apples. Moreover, there was no significant loss of nutritional value from eating peeled apples based on the nutrients investigated. © 2022 Society of Chemical Industry.
研究表明，苹果的消费对心血管疾病和某些癌症有有益的影响，这主要是由于其微量营养素和植物成分的含量。苹果皮不仅比果肉含有更多的多酚，而且可能含有农药残留。本研究旨在比较去皮和未去皮苹果中某些微量营养素和残留农药水平的含量。
去皮苹果中的农药残留浓度低于未去皮苹果。然而，无论样品是否去皮，苹果中农药残留的暴露值都从未超过可接受的日摄入量（ADI），但在成年人估计的 95 百分位（277 克/人/天）的食物摄入量中，范围在 ADI 的 0.04%至 2.10%之间。多酚、纤维、镁和维生素 C 水平的测定表明，去皮和未去皮苹果之间观察到的营养差异是微不足道的。
食用苹果（如本研究中测试的苹果）会导致未去皮苹果的农药暴露量较低，去皮苹果的暴露量更低。此外，根据所研究的营养物质，从食用去皮苹果中并没有明显的营养价值损失。 © 2022 英国化学学会。
