Abstract

Bu çalışma manta karidesi (Squilla sp.) ve mavi yengeç (Callinectes sapidus, Rathbun, 1896) atık kabuklarından elde edilen kitin ve kitosanın fizikokimyasal özelliklerinin yanı sıra yağ ve su bağlama kapasitelerini belirlemek amacıyla yapılmıştır. Çalışmada kontrol grubu olarak ticari kitin ve kitosan kullanılmıştır. Atık kabuklardan kimyasal yolla elde edilen kitin ve kitosanın yağ bağlama kapasitesi iki farklı yağ (ayçiçeği ve mısır özü) kullanılarak ölçülmüştür. Sonuç olarak, manta karidesi kitin ve kitosanının hem mavi yengeç hem de ticari kitin ve kitosandan daha yüksek yağ ve su bağlama kapasitesine sahip olduğu belirlenmiştir. Daha önce çalışılmamış ve ıskarta ürün olarak değerlendirilmiş manta karidesi kabuklardan üretilen kitin ve kitosanın yüksek yağ ve su bağlama kapasitesi nedeni ile endüstriyel alanda kullanılabileceği düşünülmektedir.

Physicochemical Characterization of Chitin and Chitosan Extracted from Shell Waste of Mantis Shrimp (Squilla sp.) and Blue Crab (Callinectes sapidus, Rathbun, 1896)

Abstract

This study was undertaken to determine the physicochemical parameters of chitin and chitosan extracted from shell waste of manta shrimp and blue crab and to determine their fat-water binding capacity. The commercial chitin and chitosan was used as a control group. Chitin and chitosan production was carried out by a chemical method. In the analysis of fat binding capacity, two different types of oil (sunflower and corn) were used. Consequently, it was determined that the chitin and chitosan of manta shrimp had higher fat-water binding capacity than the capacity of the blue crab and commercial chitin and chitosan when compared. Due to their high fat-water binding capacity of chitin and chitosan of shell waste of manta shrimp used as waste product but not studied before, they have been thought to be used in industrial field.
