Description
Summary:In this work, black and white Myrtus communis L. (myrtle) fruits some biochemical parameters were investigated such as vitamins, carotenes, functional peptides, oxidative stress markers (OSM), total phenolic (TP) and flavonoid (TF) substances, antioxidant capacity (AC) and amino acids contents. The black myrtle fruits had generally higher amounts of vitamins, TP, AC and amino acid (AA) contents than the white myrtle fruits. The biochemical contents of myrtle fruits dried in the sun light and microwave (MW) were found to be lower than the frozen fruits (P<0.05). A significant increase was observed in the amount of oxidised glutathione (GSSG) and malondialdehyde (MDA) in myrtle fruits as a result of drying (P<0.05). Amounts of total AA in the black and white myrtle fruits were found to be 31.37 and 21.89 mg g-1 DW, respectively. From the results obtained, it can be said that black myrtle fruit is a better nutrition source than white myrtle fruits and freezing is the most appropriate preservation method. Bu çalışmada, siyah ve beyaz Myrtus communis L. (mersin) meyvelerindeki vitaminler, karotenler, fonksiyonel peptidler, oksidatif stres biyomarkerları, toplam fenolik ve flavonoid madde, antioksidan kapasite ile amino asit içeriği araştırılmıştır. Siyah mersin meyvesi genellikle beyaz’a göre daha yüksek miktarda vitamin, fenolik madde, antioksidan ve amino asit içeriğine sahiptir. Güneşte ve mikrodalgada kurutulan mersin meyvelerinin incelenen biyokimyasal parametreleri dondurulmuş meyvelere göre daha düşük bulunmuştur (P<0.05). Kurutma işlemi sonucunda meyvelerin GSSG ve MDA miktarlarında önemli artış gözlenmiştir (P<0.05). Siyah ve beyaz mersin meyvelerindeki toplam amino asit içerikleri sırasıyla 31.37 ve 21.89 mg g-1 KM, olarak bulunmuştur. Elde edilen sonuçlardan, siyah mersin meyvesinin beyaz mersin meyvelerinden daha iyi bir besin kaynağı ve en uygun muhafaza yöntemin dondurma olduğu söylenebilir.
