RESUMO

Cashew has big importance in Brazilian culture of fruits, principally in Northwest region, presenting very expressive social and economic activity. Accordingly to some studies cashew apple has a high vitamin C, carotenoids and phenolics compounds contents. More than vitaminic potential, these compounds have antioxidant potential to cashew pulps. This work aimed at to evaluate the quality and the antioxidant capacity of peduncles from different commercials clones of early dwarf cashew apple tree, developed by Embrapa Agroindustria Tropical, destinated to in natura market and transformation industry, through of physical, chemistry and physical-chemical characterization, selecting the clones that presenting the best results. Ten clones, from Experimental Station of Embrapa Agroindustria Tropical, located in municipality of Pacajus-Ceara, were harvested: CCP-76, CCP-06, CCP-09, CCP-1001, BRS- 189, BRS-226, BRS-265, BRS Bahia 12, Embrapa 50 and Embrapa 51. The clones were characterized to: weight, length, color, firmness, pH, soluble solids (SS), total acidity (TA), SS/TA, total soluble sugars (TSS), vitamin C, anthocianins, yellow flavonoids, total carotenoids, condensed tannins (CT), total extractable polyphenols (TEP) and total antioxidant capacity (TAC). The peduncle presented high quality, according with the evaluated attributes, presenting raised variation between the clones, donât being verified on pH parameter, without significative statistical difference (p<0,05), between the treatments. The most detachable clones were BRS 189 and BRS Bahia 12. The first one presented good physical characteristics like the firmness, the most attractive color, being a high source of bioactive compounds like vitamin C, total anthocianins and total carotenoids, presenting the highest values in these compounds. The second one has a good texture and is a high source of vitamin C and is a excellent source of polyphenols and presenting the most value of total antioxidant capacity, between the evaluated clones. Keywords: cashew, clones, quality, bioactivies compounds, total antioxidant capacity
