巨胚功能稻的营养成分分析

分别测定了巨胚稻和相应非巨胚稻（对照）糙米的粗白质、粗脂肪、粗纤维、粗灰分等4种主要营养成分，17种氨基酸、9种矿物质、5种维生素和γ-氨基丁酸含量。结果表明：（1）同对照相比，巨胚稻糙米的粗蛋白、粗脂肪、粗纤维和粗灰分含量均有提高，平均增幅分别为11.14%、106.09%、42.21%和10.17%；（2）较对照，巨胚稻的17种氨基酸含量普遍提高，必需氨基酸含量提高2.52%-35.62%，氨基酸总量提高4.77%~37.09%；（3）巨胚稻的矿物质元素含量丰富，相比非巨胚对照，其Ca、Fe、Zn、Mn、Mg、P、K、Na和Cd的平均含量分别提高了42.89%、47.96%、38.08%、37.75%、1.75%、5.51%、13.88%、16.13%和36.69%；（4）巨胚稻的VB1、VB2、VPP、VE和叶酸含量均高于相应非巨胚对照，增幅为2.50%~214.81%；（5）巨胚稻糙米的功能成分γ-氨基丁酸（GABA）含量比相应非巨胚对照增加，平均增幅达286.58%。巨胚稻富含各种营养成分，是一种高营养功能型的稻米品系。

Analysis on the Nutrient Composition of Giant Embryo Rice

The contents of brown rice proteins, fats, crude fibre, ashs, amino acids, mineral elements, vitamin and GABA of giant embryo rice (ge-rice) and its original rice(CK) were analyzed. The results indicated that:(1)Compared with its original rice, ge-rice has an increase in the contents of brown proteins, fats, crude fibre and ash by 11.14%, 106.09%, 42.21% and 10.17%, respectively. (2)Most of the contents of 17 kinds of amino acids of ge-rice are higher than that of CK, and the essential free amino acid conte...
