Physalis cinsinin meyvesi olan altın çilek, (Physalis peruviana L.) sağlık üzerine olumlu etkileri nedeni ile ilgi çekmektedir. Bu çalışmada altın çileğin olgunlaşmamış ve olgunlaşmış meyvelerinin bazı fiziko kimyasal özellikleri (kuru madde, pH, suda çözünür kuru madde (SÇKM)), antioksidan aktivitesi ve meyveye biyoaktivite kazandıran fotokimyasallarındaki (β-karoten, organik asit, şeker ve fenolik bileşiklerindeki) değişim belirlenmiştir. Olgunlaşma seviyesi arttıkça kuru madde 19.45 to 21.01’e ve SÇKM 11.99 to 14.51’e, antioksidan kapasite 3.52’den 8.07 µmol trolox/100 g kuru ağırlık (KA)’a, toplam fenolik madde miktarı 6.27’den 19.00 mg Gallik Asit Eşdeğeri/100 g KA’a ve β-karoten miktarı 20.38’den 139.57 mg/kg KA değerine artmıştır. Gallik asit ham ve olgun meyvelerde başlıca fenolik bileşen olarak sırasıyla 495.00 ve 519.30 mg /kg KA düzeylerinde saptanırken, ham meyvelerde prosiyanidin B1, kafeik asit ve rutin saptanmamıştır. Sitrik asit miktarı 96.06’dan 83.69 mg/kg KA’a düşerken, malik asit miktarı 10.33’den 14.54 mg/kg KA’a yükselmiştir. Elde edilen sonuçlar incelenen özelliklerin meyvenin olgunluk düzeyinden etkilendiğini göstermiştir.
The fruit of the Physalis species, the golden beans (Physalis peruviana L.) is interested in the cause of its positive health effects. In this study, some physical chemical properties of the unmatched and mature fruits of gold beans (dry substance, pH, water-soluble dry substance), antioxidant activity and changes in the photokemic substances (β-carotene, organic acid, sugar and phenolic compounds) that give the fruit bioactivity have been determined. As the level of maturity increased, the dry substance increased from 19.45 to 21.01 to 11.99 to 14.51, the antioxidant capacity increased from 3.52 to 8.07 μmol trolox/100 g dry weight (KA), the total phenolic substance amount increased from 6.27 to 19.00 mg Gallic acid equivalent/100 g KA and the beta-carotene amount increased from 20.38 to 139.57 mg/kg KA. Gallic acid was identified as the main phenolic component in raw and mature fruits at the levels of 495.00 and 519.30 mg/kg KA, respectively, while prosyanidine B1, caffeic acid and routine were not identified in raw fruits. The amount of citric acid fell from 96.06 to 83.69 mg/kg KA, while the amount of ownic acid increased from 10.33 to 14.54 mg/kg KA. The results found that the characteristics studied were influenced by the level of maturity of the fruit.
ABSTRACT Golden berry fruit (Phsalis peruviana L.), which is belong to Phsalis genus, has attracted attention due to its positive effects on human health. In this study, changes in some physico-chemical properties [dry matter (DM), Soluble solid content (SSC), pH], and bioactive properties antioxidant capacity, β-carotene, organic acids, sugars and phenolic compositions of golden berry were determined at immature and mature stages. DM content increased from 19.45 to 21.01, SSC increased from 11.99 to 14.51, total phenolic compounds increased from 6.27 to 19.00 mg gallic acid equivalent/ 100 g DM and β-carotene content increased from 20.38 to 139.57 mg/kg DM) increased as fruits get matured.. Gallic acid was detected as the major phenolic compound in immature and mature fruits at the level of 495.00 ve 519.30 mg/kg DM, respectively, while procyanidine B1, caffeic acid and rutin were not determined in immature fruit. Amount of citric acid were decreased from 96.06 to83.69 mg/kg DM, while malic acid increased from 10.33 to 14.54 mg/kg DM. The results showed that the investigated attributes were affected by the maturity level.
