摘要
2003-2004年经多点多样品对香榧Torreya grandis‘Merrilli’种仁的营养成分分析证明,香榧种仁含油率为546.2～614.7 g·kg-1,脂肪酸组成以亚油酸和油酸为主,不饱和脂肪酸占脂肪酸总量的79.41%.种仁含蛋白质为121.0～164.3 g·kg-1,具有17种氨基酸,其中7种为人体必需氨基酸.种仁含有19种矿物元素.钾、钙、磷、镁含量丰富,其中钾达7.0～11.3 g·kg-1.种仁中重金属元素除个别样品镉元素超标外,其他均未检出或在安全标准以下,各种农药残毒均未检出.香榧种仁含有极其丰富的烟酸和叶酸,两者含量高于一般干水果数十倍,此类维生素具有助消化,滋润皮肤等功效,为香榧的消积美容功效找到科学根据.
By component analysis of the seed samples of Tolreya granclis ＇Merrillii＇, from many locations, the results show that the oil content of seed is 546.2 - 614.7 g· kg^-1 . The fatty acids mainly consist of linolic acids and oleic acids. So the seed oil is easily digestible and is a super edible oil with many functions such as reducing cholesterol, promoting blood circulation and regulating endocrine system. The unsaturated fatty acids account for 79.41% of total fatty acids. The seed kernels have 121.0- 164.3 g·kg^-1 protein, 17 amino acids of which seven amino acids are indispensable for health, and 19 mineral elements among which potassium （7.0-11.3 g·kg^-1）, calcium, phosphorus and magnesium contents are high. Heavy mental elements were not found or the contents below the safety standard, except that cadmium contents in few samples was beyond the safety standard. The pesticide residue was not found either. It is the first time to find that the seed kernel contains abundant vitamin nicotinic acid and folic acid, which can promote digesting and moistening skin, and both acids contents of the seed are higher than that of other dry or fresh fruits.
