Background: 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.
Results: 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.
Conclusion: 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.

The aim of this study was to compare peeled and unpeeled dehydrated apple slices of the red-fleshed 'Baya Marisa' and the white-fleshed 'Golden Delicious', to analyze the difference in the content of sugars, organic acids, and phenolic compounds during the heat process of dehydration, and to compare it with our previous study on fresh apples of the same cultivar. The purpose of these study was to see how many primary and secondary metabolites are lost in the dehydration process to better understand what is ingested by consumers in terms of nutritional value. A total of 30 phenolic compounds were identified and quantified, some of them for the first time.

In this work, the kinetics of drying and rehydration of green apple slices peeled and unpeeled (Granny Smith cv) were studied. The apple slices were dried at 50, 60, and 70 °C, and after that, rehydrated at ambient () and boiling temperature (). The drying kinetics were adjusted with the Dincer and Dost model, giving a good fit.

Many people across the world suffer from iodine (I) deficiency and related diseases. The I content in plant-based foods is particularly low, but can be enhanced by agronomic biofortification. Therefore, in this study two field experiments were conducted under orchard conditions to assess the potential of I biofortification of apples and pears by foliar fertilization.

Background: Apple peels contain phlorizin, which can reduce plasma glucose levels in a manner similar to that of inhibitors for sodium-glucose cotransporters.
Objectives: In this study, we examined the influence of a peeled apple, a sodium-glucose cotransporter-2 inhibitor (ipragliflozin) in combination with a peeled apple, and an unpeeled apple on interstitial glucose in a healthy individual across 3 experiments.
Methods: For Experiments 1, 2, and 3, the healthy volunteer consumed 327 g peeled Sun Fuji apple, took 50 mg ipragliflozin, and then consumed 327 g peeled Sun Fuji apple, or consumed 370 g unpeeled Sun Fuji apple (peel weight was 43 g), respectively.
