Analysis of Chemical Composition in some Citrus Seeds Flour

Seeds from varieties of Citrus fruits in Chengdu,namely citrus sinensis seed,rapefruit seed and orange nuclear were milled in a smasher and sieved to pass through a 60-mesh screen.The flour was extracted with Soxtex,at the same time,its content of oils was determined.Taking the defatted flour as sample,the flour was evaluated for proximate composition and mineral content.Proximate analysis showed that the citrus seeds flour was rich in protein,meanwhile, these flour was proved to be a good source for minerals Ca,Fe,Cu,Zn.As a result,the study can provide a theoretical basis for the development of the three seeds.
