| Resumo: |
The dried apple pomace composition of eleven cultivars was assessed in this work. The drying process of apple pomace spread in a thin layer in the trays of an oven with circulating heated air at 60ºC showed a 3rd order polynomial tendency and after 10 hours the product, with an equilibrium moisture of 10%, showed an homogeneous appearance according to colorimetric parameters. There are significant differences in the content of lipids, proteins, total titratable acids, total reducing sugars, dietetic fibers total phenol compounds and also in an oxidant activity. Total dietary fibers include pectin, 35%, and insoluble fibers (65%). The content of total phenolic compound, determined with the Folin Ciocalteu reagent and expressed as catechin, goes from 2.29 to 7.15 g kg-1 of dried apple pomace and the antioxidant capacity, expressed as total equivalent (TEAC), from 17.41 to 77.48 mMol g-1. A correlation of 82% between both these quality factors was found. The principal component analysis established the efficiency of total phenol compound, antioxidative capacity, total fiber and total reducing sugars to identify the best cultivar set as source of bioactive compound. Cv. M-2/00 shows high content of total phenol compound and antioxidant capacity, cv. Catarina, of pectin while cv. MRC 11/95, M-12/00, M-8/00, M6/00 e M-11/00, of malic acid and of total reducing sugars. The other cultivars show high content of fibers, ashes and lipids.
The dried apple pomace composition of 11 cultivars was assessed in this work. Significant differences in lipids, malic acid, total polyphenol compounds, total reducing sugars, and alimentary fiber content were observed among the samples. Dietary fiber was composed of 35% pectin and 65% insoluble fiber. Total polyphenol compounds (TPC), measured as chatechins, ranged from 2.29 to 7.15 mg/Kg of apple pomace. Antioxidant activity, expressed as total equivalents of antioxidant capacity (TEAC) values, varied from 17.41 to 77.48 mmMol/g and a high correlation coefficient was observed between antoxidant and polyphenol levels (R2 = 0.82). PCA results showed that apple pomaces from different cultivars may have different composition profiles and different antioxidant activity. The drying kinetics of apple pomace fitted a third order model. The results also pointed that dehydrated apple pomace could be used as raw material for inverted sugar production, after purification, and as an interesting ingredient for the production of foodstuffs rich in alimentary fibers, TPC, and antioxidants.
