Aerobik stabilite süresince paket silajlarinda renk değişimi

Bu çalışmada, paket silajlarda açım sonrası silaj yüzeyinin renginde meydana gelen değişimler ile bazı kimyasal ve mikrobiyolojik parametreler, altı günlük aerobik stabilite süresince izlenmiştir. Uygulamalar; kontrol (K), Silo-king firma dozu (RF), silo-king çift doz (R2), Simsilaj firma dozu (SF) ve Simsilaj çift doz (S2) olarak belirlenmiştir. Mısır bitkisi, silaj paketleme makinası ile paketlenmiştir. Doksan günlük depolama sonrasında açılan örneklerden aerobik stabilite süresince CIE Lab renk sisteminde renk analizleri yapılmıştır. Araştırmada ayrıca, sarılık (yı*) indeksi de ölçülmüştür. Deneme sonucunda, aerobik stabilitenin silaj yüzey rengi üzerine etkisi önemli bulunmuştur (p

Color changes of package silage In period of aerobic stability

In this study, changes on color of the silage surface, chemical and microbiological parameters in six days period of aerobic stability of package silage were investigated. For this purpose, the effect of the silage additive materials and treatments dose also were examined. Treatments were determined as Control (C), Silo-king firm dose (FD), Silo-King double dose (D2), Sim-Silage firm dose (SF), and Sim-Silage double dose (S2). Maize was ensiled using a package silage machine. The package silages opened after three months storage was analyzed for colors during aerobic exposure. In this research, yellowness (yı*) indicates were also measured to show the effect of fermentation process on the silage color properties. As the result of experiment, it was found that aerobic stability have significant effects on color of the silage surface (all parameters) statistically (p<0.05). The lowest color alteration (ΔE) was estimated as 8.96 in S2 treatment. The color alteration also was increased 96 h when increased at pH and temperature. The highest $CO _2$ values were found at firm dose treatments.
