油用牡丹籽粕营养成分分析研究

Analysis of nutrient compositions of peony seed meal

测定油用牡丹籽粕粗脂肪、粗纤维、粗多糖、粗蛋白、氨基酸及微量元素等营养成分的含量。结果表明:牡丹籽粕粗脂肪含量6.19%,粗纤维3%,粗多糖7.67%,粗蛋白28.12%,氨基酸总量为25.22%,氨基酸种类齐全,其中必需氨基酸含量占34.67%,非必需氨基酸含量占65.33%。微量元素铜、铁、锌、锰的含量分别为20.95、651.30、172.63、35.05μg/g。牡丹籽粕营养成分丰富,可进一步加强其资源化利用。

The content of crude fat,crude fiber,crude polysaccharide,crude protein,amino acids and microelement from peony seed meal were determined.The results showed that the content of crude fat was 6.19%,crude fiber was 3%,crude polysaccharide was 7.67%,crude protein was 28.12%,and total amino acids was 25.22%,which including 34.67%essential amino acids and 65.33%non-essential amino acids.And the microelement Cu,Fe,Zn,Mn were also determined.The contents of Cu,Fe,Zn,Mn were 20.95,651.30,172.63,35.05μg/g,respectively.The peony seed meal is rich in nutrients and can be further studied and exploited.
