Özet:

 In this study, the peel, pulp, and leaves of the Scarlet Spur apple variety were freeze-dried and powdered. Moisture content  and color analyses were performed on the powdered samples. The dried powders were extracted using a conventional method with an ethanol:water 42:58 vv mixture. Among the extracts and juice, the leaf extract exhibited the highest values in terms of ABTS antioxidant activity 104.85 mg TEg, DPPH free radical scavenging activity 9.96 mg TEg, and total phenolic content 84.72  0.04 mg GAEg. It was observed that extracts obtained from peel, pulp, and leaves exhibited inhibitory effects on the pathogens Eschrichia coli ATCC 25922 E. coli, Staphylococus aureus ATCC 25923 S. aureus, Listeria monocytogenes ATCC 7644 L. monocytogenes. The leaf extract showed the highest effect on pathogens with a concentration of 5 log CFUml. It is thought that the richness of the leaf in total phenolic content contributes to this effect. This study demonstrates that extracts obtained from apple tissues, considered as waste, can be used as antimicrobial agents against pathogenic microorganisms and as natural antioxidant substances.

 Bu çalışmada Scarlet Spur elma çeşidinin kabuğu, posası ve yaprakları dondurularak kurutulmuş ve toz hale getirilmiştir. Toz örneklerin nem  ve renk analizleri yapılmıştır. Kurutulan tozlar etanol:su 42:58 vv karışımıyla klasik yöntemle ekstrakte edilmiştir. Elde edilen ekstraktlar ve meyve suyu arasında ABTS antioksidan aktivitesi 104,85 mg TEg, DPPH serbest radikali indirme aktivitesi 9,96 mg TEg ve TFFM bakımından 84,72  0,04 mg GAEg en yüksek değere sahip olan ekstraktın yaprağa ait olduğu belirlenmiştir. Kabuk, posa ve yapraktan elde edilen ekstraktların Eschrichia coli ATCC 25922 E. coli, Staphylococus aureus ATCC 25923 S. aureus, Listeria monocytogenes ATCC 7644 L. monocytogenes patojenleri üzerine inhibisyon etkiye sahip olduğu gözlemlenmiştir. 5 log KOBml konsantrasyona sahip patojenler üzerine en yüksek etkiyi yapraktan alınan ekstraktlar göstermiştir. Yaprağın TFMM bakımından zengin olmasının bu etkiyi gösterdiği düşünülmektedir. Bu çalışma ile, elma atığı olarak düşünülen dokularından alınan ekstraktların patojen mikroorganizmalara karşı antimikrobiyal ajan olarak ve doğal antioksidan madde olarak kullanılabileceğini göstermektedir.
