Farklı Nem İçeriklerindeki Siyez Buğdayı Tohumlarının Karbondioksit Değişimleri ve Bazı Mekanik Özelliklerinin Belirlenmesi

Öz

Bu çalışmada; farklı nem içeriklerindeki (%5, 10.5, 15, 20, 25) kavuzlu siyez buğdayı tohumlarında (Triticum monococcum L.) karbondioksit (CO₂) solunum hızında meydana gelen değişimler ve bazı mekanik özellikler araştırılmıştır. Tohumlar 10 °C’ de 3 ay süreyle sıcaklık ve nem test kabininde depolanmıştır. Bu süre sonunda CO₂ değişimi %5, 10.5 ve 15 nem içeriklerinde 120 saat, %20 ve 25 nem içeriklerinde sırasıyla 26 ve 29 saat süreyle ölçüm yapılmıştır. Araştırmanın sonucunda %5, 10.5, 15, 20 ve 25 nem içeriklerindeki CO₂ düzeyleri sırasıyla 504-555, 510-578, 568-1074, 762-9999 ve 1500-9999 ppm olarak tespit edilmiştir. Minimum CO₂ solunum hızı 120. saatte %5 ve 10.5 nem içeriğinde 0.06 mgCO₂ kg^-1 h^-1 olarak belirlenmiştir. Maksimum CO₂ solunum hızı ise %25 nem içeriğinde 1. saatte 18.09 mgCO₂ kg^-1 h^-1 olarak tespit edilmiştir. Artan nem içeriğine bağlı olarak mühendislik özelliklerin artış gösterdiği belirlenmiştir. Elde edilen sonuçlara bağlı olarak tohumların yüksek nem içeriğinde bozulması hızlanarak depo iç ortamının çevresel koşulları (sıcaklık ve bağıl nem) olumsuz olarak etkilenebilecektir. Farklı nem içeriklerine sahip tohumlarda daha düşük solunum hızları %5 nem içeriğinde belirlenmiştir. Ancak depolamada %5’lik nem düzeyini sağlamak daha fazla soğutma veya havalandırma maliyetine neden olacağından siyez buğdayı tohumlarının %10.5 nem içeriğinde depolanması tohumların mühendislik özellikleri açısından önerilmektedir.

Determination of Carbon Dioxide Changes and Some Mechanical Properties of Siyez Wheat Seeds in Different Moisture Content

Abstract

The changes in carbon dioxide (CO₂) respiration rate and some mechanical properties of unhulled siyez wheat (Triticum monococcum L.) in different moisture contents (5, 10.5, 15, 20, 25%) were investigated in this study. The seeds were storaged in the temperature and moisture test chamber at 10 °C for 3 months. At the end of this period, CO₂ changes were measured thourghout 120 hours at 5, 10.5 and 15% moisture contents and 26 and 29 hours at 20 and 25% moisture contents. As a result of the study, CO₂ levels of 5, 10.5, 15, 20 and 25% moisture contents were ranged 504-555 ppm, 510-578 ppm, 568-1074 ppm, 762-9999 ppm and 1500-9999 ppm, respectively. Minimum CO₂ respiration rate was determined as 0.06 mgCO₂ kg^-1 h^-1 in 5 and 10.5% moisture content at 120^th hours. The maximum CO₂ respiration rate was determined as 18.09 mgCO₂ kg^-1 h^-1 at 1^th hour in 25% moisture content. It was determined that the some engineering properties increased due to increased moisture content. Depending on the results obtained, the degradation of the seeds will accelerate and the indoor environmental conditions (temperature and relative humidity) in storage may be adversely affected by high moisture contents. The lower respiration rates in seeds with different moisture contents were determined at 5% moisture content. However, it is determined that the seeds of wheat can be stored in 10.5% moisture content since storage at 5% moisture content may cause more cooling or ventilation cost.
