Nutritional properties and potential values of cordia sebestena seed and seed oil

Az kullanılan hammaddelerin gelifltirilmesinin ivme kazanması ile iyi bilinen tohum ve tohum yağlarına olan aflırı bağımlılıktan ve bunun sonucundaki yüksek maliyetten dolayı geleneksel ve endüstriyel uygulamalar için az bilinen tohum ve tohum yağları türetilmifltir. Bu nedenle Cordia sebestena tohum ve tohum yağının kullanım potansiyeli bakımından besinsel özelliklerinin değerlendirilmesine yönelik bu çalıflma yapılmıfltır. Tohum yağında literatürde rapor edilen çeflitli analizler kullanılarak yağ asidi profili incelenmifl ve karakterize edilmiflken, tohumda ise genel bileflim, mineral bileflenler ve anti-besinsel faktörler arafltırılmıfltır. Sonuçlar tohumun iyi bir yağ (%40.3 ± 0.8) ve protein (%11.5 ± 0.6) kaynağı olabileceğini göstermektedir. Tohum aynı zamanda Mg, Ca ve Na benzeri bazı makro-elementler ile esansiyel bir mikro-element olan Zn kaynağı olabilir. Anti-besinlerden fitat, tanen ve oksalat içeriği yüksektir ve gıdalarda tohumun kullanımı sakıncalı olabilir. Bu maddeler belki geleneksel gıda iflleme yöntemleri ile giderilebilir. Tohum yağının özellikleri onun alkid reçine sentezinde, biyodizel ve sabun üretiminde kullanıfllı olabileceğini göstermektedir. Yağ asidi profili toplam yağın %71.1 oranında insan tüketimi için iyi bir yağ asidi olan oleik asiti (C18:1) ağırlıklı olarak bulundurduğunu göstermektedir. Cordia sebestena tohumu ve tohum yağının önemli kullanım alanları olabileceği görülmüfltür, ancak tohum yağının aminoasit profili ve anti-besinler üzerine geleneksel ifllemlerin etkileri konularında daha fazla çalıflmaya ihtiyaç vardır.

Cordia sebestena tohumunun ve tohum yağının besinsel özellikleri ve potansiyel değeri

The impetus for development of underutilized, lesser known seed and seed oils for domestic and industrial applications is derived from the overdependence on the well known ones and the resultant high cost of such. This study was therefore conducted to evaluate the nutritional properties of Cordia sebestena seed and seed oil for their potential applications. Proximate analysis, mineral components and anti-nutritional factors were investigated in the seed while the seed oil was characterized and investigated for its fatty acid profile using various methods reported in literatures. The results show that the seed could be a good source of oil (40.3 ± 0.8%) and protein (11.5 ± 0.6%). It could also supply some macronutrients like Mg, Ca and Na along with Zn which is an essential micronutrient. The anti-nutrient contents, phytate, tannins and oxalate were high and can be drawbacks to the applications of the seed in food. These may be removed by domestic processing. The properties of the seed oil show that it may be useful in alkyd resin synthesis, biodiesel and soap production. The fatty acid profile shows that the seed oil has predominantly oleic acid (C18:1) being 71.1% of the total fatty acid in the oil which is good for human consumption. Cordia sebestena seed and seed oil demonstrate potentially valuable applications, there is however need to further study the amino acid profile of the seed and the effects of domestic processing on the anti-nutrient components.
