These compounds vary in their composition and concentration, among cultivars and fruit tissues. In this research, the total phenolic content Folin-Ciocalteau assayantioxidant capacity Ferric Reducing Antioxidant Power, FRAP assay and mineral composition in three fruit tissues peel, pulp and whole fruitof apple cultivars commonly used for dried apple production in Chile, were studied.
In addition, the physical-chemical characteristics dry weight, pH, titratable acidity, soluble solids content and color were also evaluated. The results indicated that the total phenolic content, the antioxidant capacity, and the mineral composition, of peel were substantially higher than those of whole fruit, and pulp for all the cultivars studied. Additionally, a high correlation between total phenolic content and antioxidant capacity was found in all the cultivars and fruit tissues analyzed, except in the apple pulp.
On the other hand, the physical and chemical composition differed among cultivars and fruit tissues. In conclusion, our results demonstrated that the total phenolic content, antioxidant capacity, mineral composition, and physical and chemical characteristics vary considerably depending on the apple cultivars and fruit tissues analyzed. It has been hypothesized 1. In addition to vitamins C and E and carotenoids, the bioactive non-nutrient phytochemicals such as phenolic compounds, are supposed to play an important role in the prevention of major chronic diseases Arts and Hollman, ; Scalbert et al.
In effect, phenolic compounds are major antioxidants of our diet Scalbert et al. On the other hand, main minerals and essential trace elements are very important in biological processes, and play a vital role in normal growth and development and have also been involved in the prevention of some chronic diseases Gorinstein et al. C, which explains only 0. In Chile, apples are one of the most important fruits. Recently, commercial apple production has reached 1.
In apples, as well as in other fruits, the phenolic content vary among different cultivars, within different tissues of Lombriz roja californiana reproduccion asexual fruit, growing conditions, cultural practices, ripeness during harvest, post-harvest storage conditions, and processing Imeh and Khokhar, ; Boyer and Liu, Several researches reported that apple peel may contain more antioxidants and antioxidant capacity than the pulp fraction or the whole fruit Wolfe et al.
In this context, a recent study has shown an association between some of these characteristics and the total phenolic content and the antioxidant capacity. This information would be important for the consumer, as they could recognize, for example, a more nutritional apple by its characteristics such as peel color Drogoudi et al.
No comprehensive data have been reported on the physical-chemical composition, total phenolic content, antioxidant capacity and mineral composition of different apple cultivars, commonly used in Chile for the production of dried apples.
Since Chile is an important exporter of dried apple, it is necessary to study the composition of the raw material, to ensure product quality, and to assess the potential use of secondary products such as apple peel. Therefore, the objectives of this research were: The average air temperature ranged between 7.
The fruits used in the evaluations were picked randomly; then, placed in polyethylene bags and transported in ice to the Nutrition and Food "Lombriz roja californiana reproduccion asexual" Institute. Samples were then selected to eliminate damaged and poor quality units to obtain uniformity. Fruits were washed in water with chlorine 0.
