A study on the Application of Organic Coconut Oil on Lemon, Siberian pine, American Walnut, Monterrey Pine, and Magnolia Woods

Abstract

In this study, changes in color parameters [a*: red color tone value, b*: yellow color tone value, C*: chroma value, L*: lightness value, and ho: hue angle value] occurring on wood surfaces of Monterrey pine (Pinus radiata D Don), Siberian pine (Pinus sibirica), lemon (Citrus limon (L.) Burm.), magnolia (Magnolia grandiflora L.), and American walnut (Juglans nigra L.) wood species after the application of organic coconut oil were compared. The analysis of variance determined significant results for color parameters in all wood species and applications. ΔE* values after application were obtained as 7.29 for Monteri pine, 3.27 for lemon, 10.43 for American walnut, 9.74 for magnolia, and 12.40 for Siberian pine. Decreases in ho and L* values were obtained with oil application in all wood species, while increases were found in the a* parameter. Additionally, a decrease was observed in the C* and b* parameters in American walnut wood, while increases were observed in all other wood species. The study revealed that the color parameters changed with the use of coconut oil.

Limon, Sibirya Çamı, Amerikan Cevizi, Monteri Çamı ve Manolya Ahşaplarında Organik Hindistan Cevizi Yağı Uygulamasının Yapılması Üzerine Bir Çalışma

Abstract

Bu çalışmada, Monteri çamı (Pinus radiata D Don), Sibirya çamı (Pinus sibirica), limon (Citrus limon (L.) Burm.), manolya (Magnolia grandiflora L.) ve Amerikan ceviz (Juglans nigra L.) ağaç türlerine ait ahşap malzeme yüzeylerine organik Hindistan cevizi yağı uygulaması sonrasında meydana gelen renk parametrelerinde [a*: kırmızı renk tonu değeri, b*: sarı renk tonu değeri, C*: kroma değeri, L* ışıklılık değeri ve ho: ton açısı değeri] değişimler karşılaştırılmıştır. Varyans analizlerinde bütün ahşap türlerinde ve uygulamalar üzerinde renk parametreleri için anlamlı sonuçlar belirlemiştir. ∆E* değerleri uygulama sonrasında Monteri çamı için 7.29, limon için 3.27, Amerikan cevizi için 10.43, manolya için 9.74 ve Sibirya çamı için 12.40 olarak elde edilmiştir. Bütün ahşap türlerinde yağ uygulaması ile ho ve L* değerlerinde azalmalar elde edilirken, a* parametresinde artışlar bulunmuştur. Buna ek olarak, C* ve b* parametrelerinde Amerikan cevizi odununda azalma tespit edilirken, diğer bütün ahşap türlerinde artışlar görülmüştür. Çalışmada kullanılan Hindistan cevizi yağı ile renk parametrelerinin değiştiği görülmüştür.
