PAZI TOZU İLAVESİ VE ÜRETİM FAKTÖRLERİNİN ISIL İŞLEM GÖRMÜŞ FERMENTE SUCUKLARDA KALINTI NİTRİT MİKTARI ÜZERİNE ETKİSİ

Bu çalışma, ısıl işlem görmüş sucuklarda doğal bir nitrat kaynağı olarak pazı (Beta vulgaris L. var. cicla) tozunun (PT) kullanımını değerlendirmek amacıyla gerçekleştirilmiştir. Kontrol (KN) örneği 150 ppm sodyum nitrat; PT1 örneği 75 ppm sodyum nitrat ve 75 ppm-nitrat içeren PT; PT2 örneği ise 150 ppm-nitrat içeren PT ile hazırlanmıştır. Örneklerin kimyasal kompozisyonu arasında farklılık tespit edilmemiştir (P >0.05). PT konsantrasyonlarının artması; pH değerinin yükselmesi, asitliğin azalması ve L*, a* ve b* değerlerinin düşmesine neden olmuştur (P <0.05). Sucuk hamuru ve fermentasyon sonrasında en yüksek kalıntı nitrit konsantrasyonları KN örneklerinde kaydedilmiştir (P <0.05). Isıl işlem, PT1 ve PT2 örneklerinin kalıntı nitrit düzeylerini önemli ölçüde etkilemiş; son ürün örnekleri arasında PT2 grubunun en yüksek kalıntı nitrit miktarına sahip olduğu belirlenmiştir (P <0.05). Doğal nitrat içeren kaynaklarla birlikte ek bileşenlerin ve/veya yenilikçi uygulamaların kullanılması gerektiği sonucuna varılmıştır.

RESIDUAL NITRITE CONTENT OF HEAT-TREATED SUCUK AS AFFECTED BY CHARD POWDER INCORPORATION AND PROCESSING

This study was conducted to evaluate the utilization of chard (Beta vulgaris L. var. cicla) powder (CP) as a natural nitrate source in heat-treated sucuk (fermented Turkish sausage). Control (CN) sample was formulated with 150 ppm sodium nitrate, whereas CP1 sample was formulated with 75 ppm sodium nitrate plus 75 ppm-nitrate containing CP, and CP2 sample was formulated with 150 ppm-nitrate containing CP. No differences were obtained in chemical composition (P >0.05). Increased CP level resulted in increased pH and decreased acidity and L*, a*, and b* values (P <0.05). The highest residual nitrite concentrations were recorded in CN samples in the dough and after fermentation (P <0.05). Heat treatment affected residual nitrite levels of CP1 and CP2 samples, and in final products, CP2 samples had the highest residual nitrite content (P <0.05). Consequently, utilization of additional ingredients and/or innovative applications would be necessary in combination with naturally nitrate-containing sources.
