Determining the Effect of Storage Conditions on the Quality Changes of Avocado (Persea americana Mill.) Grown in the Alanya Region

Abstract

Avocado (Persea americana Mill.) is a significant nutritional source due to its high oil content, vitamin E, and fiber composition. In Turkey, the production and consumption of avocados have been increasing, with different varieties being harvested in Alanya between September and May. As a climacteric fruit, avocado undergoes rapid respiration and ripening after harvest, making storage conditions crucial. However, a lack of reliable resources documenting the characteristics of locally grown varieties poses challenges for producers and entrepreneurs. This study examines four avocado varieties (Zutano, Bacon, Fuerte, and Hass) grown in Alanya under different storage conditions (4°C and 14°C, 85% relative humidity) to evaluate their physical, chemical, and microbiological properties. Analyses conducted on days 1, 7, and 14 of storage revealed no microbial growth in samples stored at 4°C. At 14°C, microbial growth was monitored at lower than 5 logarithmic units in all varieties except Bacon, where no growth occurred during 14 days of storage. Regardless of storage temperature, all samples showed an increase in the range of 12 to 39 percent in total oil content over time. The predominant saturated fatty acids identified were palmitic acid (16:0), heptadecanoic acid (17:0), stearic acid (18:0), arachidic acid (20:0), and heneicosanoic acid (21:0). In conclusion, this research revealed that storage at 14°C should be applied to preserve postharvest fruit quality, the development of value-added products when taking account, the cold stress of the fruit.

Öz

Avokado (Persea americana Mill.), yüksek yağ içeriği, E vitamini ve lif kompozisyonuyla önemli bir besin kaynağıdır. Türkiye’de üretimi ve tüketimi artan avokadonun Alanya bölgesinde Eylül-Mayıs ayları arasında farklı çeşitleri hasat edilmektedir. Klimakterik bir meyve olan avokado, hasattan sonra hızlı solunum ve olgunlaşma sürecine girer, bu da depolama koşullarını kritik hale getirir. Ancak, bölgedeki üreticilerin ve ticari girişimcilerin çeşit özelliklerini içeren güvenilir kaynak eksikliği dikkat çekmektedir.Bu çalışmada, Alanya’da yetiştirilen dört avokado çeşidinin (Zutano, Bacon, Fuerte, Hass) farklı depolama koşullarında (4°C ve 14°C, %85 bağıl nem) fiziksel, kimyasal ve mikrobiyolojik özellikleri incelenmiştir. Depolamanın 1., 7. ve 14. günlerinde yapılan analizlerinde, 4°C’de muhafaza edilen örneklerde mikrobiyolojik üreme gözlenmemiştir. 14°C’de ise Bacon çeşidi dışındaki örneklerde toplam aerobik mezofilik bakteri ve maya/küf üremesi gerçekleşmiş, ancak mikrobiyal yük 5 logaritmik birimin altında tespit edilmiştir. Depolama sıcaklığından bağımsız olarak tüm örneklerdeki toplam yağ oranı yüzde 12 ile yüzde 39 aralığında artış göstermiştir. Başlıca doymuş yağ asitleri arasında palmitik asit (16:0), heptadekanoik asit (17:0), stearik asit (18:0), araşidik asit (20:0) ve heneikosanoik asit (21:0) yer almıştır. Araştırma sonuçları; hasat sonrası meyve kalitesinin korunması, avokadonun katma değerli ticari ürünlere işlenmesi ve soğuk zararlanması da göz önüne alınınca depolamanın 14°C’de yapılması gerektiğini ortaya çıkarmıştır.
