“…When considering the total phenolics measured in both skins and pulps together, this resulted in only PI having fewer phenolics than GD (5059 versus 6433 μg g −1 dry weight); the other three cultivars had more phenolics, with BB reaching values of 12 040 μg g −1 dry weight, which is almost double that of GD. This information clearly has great relevance for several key apple characteristics, as the antioxidant, nutritional, and organoleptic properties of the ancient cultivars of apples studied here differ greatly from the properties of GD as analyzed in this study and as reported in the literature 16,43,47,48 …”

BACKGROUND Since the second half of the 20th century, the cultivation of ancient and local apple cultivars has almost disappeared from orchards in Italy. Some of these ancient apple cultivars often possess high nutraceutical values and display lower allergenicity than the modern ones, supporting the so‐called ‘green revolution’ theory. RESULTS In this study, the phenolic composition and the antioxidant activity of five ancient apple cultivars (‘Belfiore’, ‘Pomella Genovese’, ‘Gravenstein’, ‘Bella del Bosco’, and ‘Piatlin’) were compared with a ‘Golden Delicious’ commercial cultivar. Additionally, apples were tested for their potential allergenicity by detecting the presence of Mal d 3, a non‐specific lipid transfer protein that represents the main apples' allergen. All apples came from northern Italy (Trentino Region) and were organically produced. Results showed that, for all cultivars, the skins contained more polyphenols than the pulps. ‘Bella del Bosco’ had the highest amount of polyphenols and antioxidant activity, whereas ‘Piatlin’ had the lowest phenolic content. All ancient cultivars presented a higher amount of pulp phenolic compounds than ‘Golden Delicious’. Immunoblotting techniques showed that ‘Bella del Bosco’ and ‘Piatlin’ had very low quantities of Mal d 3 allergen; hence, they can be considered hypoallergenic cultivars. CONCLUSIONS The preservation of ancient apple cultivars would be of great importance, not only to maintain the biodiversity but also for their nutritional properties. The hypoallergenic activity of some of these cultivars could be of interest also for the preparation of different apple‐based products. © 2020 Society of Chemical Industry

“…Another mechanism concerns the influence of phenolic compounds on mast cells and the prevention of histamine secretion [ 27 , 35 , 42 , 66 ]. Thus, polyphenols are able to influence the binding between IgE antibodies and the FCεRI receptor on the mast cell surfaces [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 ], resulting in a lower amount of released histamine and, thus, in a lower allergic recruitment [ 35 ].…”

Relationship between Phenolic Compounds, Antioxidant Properties, and the Allergenic Protein Mal d 1 in Different Selenium-Biofortified Apple Cultivars (Malus domestica)

Notable parts of the population in Europe suffer from allergies towards apples. To address this health problem, the analysis of the interactions of relevant allergens with other substances such as phenolic compounds is of particular importance. The aim of this study was to evaluate the correlations between the total phenolic content (TPC), polyphenol oxidase (PPO) activity, antioxidant activity (AOA), and the phenolic compound profile and the content of the allergenic protein Mal d 1 in six apple cultivars. It was found that the PPO activity and the content of individual phenolic compounds had an influence on the Mal d 1 content. With regard to the important constituents, flavan-3-ols and phenolic acids, it was found that apples with a higher content of chlorogenic acid and a low content of procyanidin trimers and/or epicatechin had a lower allergenic potential. This is probably based on the reaction of phenolic compounds (when oxidized by the endogenous PPO) with proteins, thus being able to change the conformation of the (allergenic) proteins, which further corresponds to a loss of antibody recognition. When apples were additionally biofortified with selenium, the composition of the apples, with regard to TPC, phenolic profile, AOA, and PPO, was significantly affected. Consequently, this innovative agronomic practice seems to be promising for reducing the allergenic potential of apples.

“…They gathered the main existing knowledge about phenolic compound extraction and analysis of their profile using spectrophotometric and chromatographic methods; however, since then, some new insights have been presented in this respect. The Folin-Ciocalteu's reagent is still commonly used to spectrophotometrically characterize the total content of phenolic compounds in apples and their products [Azlan et al, 2018;Bakir et al, 2016;Dhyani et al, 2018;Xu et al 2016 ]. Total phenolic content is one of the most frequently analyzed factors, even after it was shown that the spectrophotometric method can lead to inaccurate results because of the strong interference of sugars and proteins in the assay results [Escarpa & Gonzalez, 2001].…”

and high environmental pollution. The consumption of fruits and vegetables is highly recommended to support the body in this respect. The main antioxidants found in fruits and vegetables are A, E, and C vitamins; β-carotene; lycopene; and a diverse group of compounds named phenolics. Therefore, it is hard to select one specific compound responsible for health benefits. That is why, Ohr [2004] stated that "scientists are currently studying how mixtures of antioxidants … work together. They are looking for synergistic effects among individual antioxidants." The most important group of antioxidants is the phenolic compounds (Figure 1). They are organic chemical compounds with at least one phenol unit, represented by, i.a., tannins (hydrolysable and condensed), flavonoids, and lignans. Phenolic compounds can be found in a variety of plant species. Their high content is correlated with antioxidant activity, which decreases the risk of coronary disease and protects against neurodegeneration [Giacalone et al., 2015]. The positive effect of flavonoids on memory improvement was also studied [Whyte & Williams, 2011]. Of 12 epidemiological surveys about coronary heart disease risk assessment compared by Arts & Hollman [2005], seven demonstrated the protective effects of a diet enriched with polyphenols. An inverse relationship has also been determined between poly
