The effect of conservation defects on the suede quality of double-face

Bu araştırmada kürk-süetlerin süet kalitesi üzerine mikroorganizmaların etkisi incelenmiştir. Tuzla konservelenmiş koyun derisi örneklerinin bakteri sayısı katı ortamda 1.8x106-4.3x107 cfu/g olarak ve % 10-30 NaCI içeren halofil ortamda 1.9x106-4.7x107 cfu/g olarak bulunmuştur. Tuzlu koyun derilerinin 4.4x101-2.0x104 cfu/g sayıda fungus içerdiği belirlenmiştir. Halofilik bakterilerin % 53-74' ü ve fungusların %39-58' iproteolitik aktivite gösterirken, halofilik bakterilerin %47-62' si ve fungusların %35-54' ü lipolitik aktivite göstermiştir. Kürk-süetlerin süet tarafındaki açık renkli kusurlu kısımların mikroorganizmalardan kaynaklandığı ve toplam kürk-süetlerin % 35' inde bu kusurların bulunduğu gözlemlenmiştir. Sonuç olarak; koyun derilerinin et kısımlarındaki mikroorganizmaların proteolitik ve lipolitik aktivitelerinin süet kalitesini düşürdüğü ve bunun ekonomik kayıplara neden olduğu ortaya konulmuştur

Kürk-süet kalitesine konservasyon hatalarının etkisi

In this research, the effects of microorganisms on suede quality of double-face leather were examined. The bacterial numbers on salted sheepskin samples were found as 1.8x106-4.3x107 cfu/g on solid medium and 1.9x106-4.7x107 cfu/g on halophile medium containing 10-30% NaCI. However it was found that salted sheepskins contained 4.4x101-2.0x104 cfu/g of fungi. While 53-74% of halophilic bacteria and 39-58% of fungi showed proteolytic activity, 47-62% of halophilic bacteria and 35-54% of fungi showed lipolytic activity. It was observed that defective light stained areas on suede surface of finished double- face leathers were caused by microorganisms on salted sheepskins and that these defects correspond to 35% of the total double-face leathers amount. Consequently, it was decided that the proteolytic and lipolytic activities of microorganisms on the flesh side of the sheepskins decreased the suede quality and caused economical losses.
