Kullanılmış Kahve Telvesinin Lif Kaynağı Olarak Değerlendirilme Potansiyeli

Öz

Tarih boyunca insanları ustaca bir araya getiren kahve insanların severek tükettiği bir içecek olarak günümüze gelmiştir. Kahve, oldukça zahmetli birçok işlem sonucu üretilmektedir ve dünyada atık yönetimi konusunda gelişen bilinç neticesinde kahve endüstrisi atıkları da günümüzde yeniden kazanılmaya çalışılmaktadır. Bunun sonucu olarak kahve çekirdeği zarı, cascara ve kullanılmış kahve telvesi gibi yan ürünler değerlendirilmeye çalışılmakta ve bu konuda giderek artan sayıda çalışmalar yapılmaktadır. Bu çalışmada, hem kahve endüstrisi atığı olarak hem de evsel kahve tüketimi sonucu oluşan kullanılmış kahve telvesinin diyet lifi olarak kullanılma potansiyeli incelenmiştir. Dünyada her gün yaklaşık 2.5 milyar fincan kahve tüketildiği ve her bir fincan kahve için ortalama 11 g taze kahve kullanıldığı düşünülerek her yıl yaklaşık 500 bin ton atık kahve telvesi oluştuğu düşünülmektedir. Bu kadar büyük ve değerli bir atığın tekrar değerlendirilmesi gıda endüstrisi açısından oldukça büyük bir önem arz etmektedir.

Spent Coffee Grounds As A Potential Fiber Source

Abstract

Coffee brought people together throughout history, and today, people still consume coffee willingly. Coffee production includes many laborious processes that results in the formation of some waste materials. As a result of the awareness about waste management, coffee industry wastes are now target for the recovery process around the world. Therefore, coffee byproducts such as coffee silverskin, cascara, and spent coffee grounds are tried to be recycled, and an increasing number of studies have been carried out on this subject. In this study, the potential of role of spent coffee grounds as dietary fiber was discussed. Spent coffee grounds are wastes from both the coffee industry and domestic coffee consumption. In the world, approximately 2.5 billion cups of coffee are consumed every day. For every cup of coffee, about 11 g of fresh coffee is used. So it is thought these numbers, around 500 thousand tons of waste coffee grounds are produced every year. Recycling such a large and valuable waste has great importance for the food industry.
