Some astringency is inherent in tea, but green tea is more astringent than black. Sugar content does not increase after harvest, but acids are broken down during ripening, thus decreasing tartness. 一定程度的收敛性是茶中固有的,而绿茶比红茶为涩。采收以后,糖份不会再增加,果酸渐渐的分解,降低蓝莓的酸涩味。
Ice cream produced with black food ingredients not only has improved sensory qualities but also has increased contents of protein, vitamin, minerals and unsaturated fatty acids, and the nutrients from botanic foods and meat products was combined together in the black ice cream. 黑色营养冰淇淋能增加冰淇淋的色、香、味,又可大幅度提高冰淇淋中的蛋白质、维生素、无机矿物元素和不饱和脂肪酸的含量,实现了动植物营养成分的互补。
Application of Glass Capillary Column Coated with Graphitized Carbon Black in the Analysis of Fatty Acids by Gas Chromatography 石墨化碳黑色谱柱在分析脂肪酸方面的应用
A Study on the Physiological Biochemical Mechanisms of Tung Oil Tree Varieties Resisting Black Spot(ⅰ) The relations of the resistance of varieties to free amino acids 、 polyphenol substances and flavonoids 油桐品种抗黑斑病生理生化机制研究(Ⅰ)品种抗性与游离氨基酸、多酚类物质、黄酮类化合物含量之关系
To study the effect of low molecular weight organic carboxylic acids on the adsorption of heavy metal ions on black carbon, the adsorption of Pb2+ and Cd2+ on black carbon with the four organic acids was investigated using the equilibrium sorption technique. 为探讨低分子量有机酸对黑碳吸附重金属离子的影响,由玉米秸秆燃烧物提取黑碳,用平衡吸附技术研究了有机酸对黑碳吸附铅(Pb2+)和镉(Cd2+)的影响。
Measured chyme amino acids, turnover and digest rate of microbial protein amino acids of different part of nutrient canal in Liuyang black goat, with diet combining analysis data of muscle amino acids and growth characteristic of Liuyang black goat, determined specific amino acids infusing capacity. 测定基础日粮条件下浏阳黑山羊消化道不同部位的食糜氨基酸和微生物蛋白质氨基酸的流通量和消化率,结合肌肉氨基酸分析数据和山羊生长特点,确定具体的氨基酸灌注剂量。
The analysis by GC-MS and HPLC shows that the petroleum fraction and chloroform fraction of the black rice pericarp extract are mainly fatty acids. The compositions of ethyl acetate fraction, normal butyl alcohol fraction, and water fraction differs each other significantly. 通过GC-MS和HPLC分析,黑米皮提取物的石油醚部和氯仿部成分以脂肪酸为主,其乙酸乙酯、正丁醇和水部之间成分构成差异较大。
The adsorption amount of Pb2+ and Cd2+ on black carbon first increased and then decreased with the concentration of organic acids increasing when organic acids significantly enhanced the adsorption of Pb2+ and Cd2+ on black carbon. 当有机酸促进Pb2+和Cd2+吸附时,随有机酸浓度的提高,Pb2+和Cd2+的吸附量先升高后下降,且有机酸对黑碳吸附重金属离子的影响随有机酸和重金属离子的特性而异。
This paper was studied the total sugar, total acid, vitamin C, pigment, amino acids and inorganic elements in black current fruit and the fatty acids in its seed. 对黑穗醋栗不同品种果实中总糖、总酸、维生素C、红色素、氨基酸、无机元素及种子中脂肪酸种类及含量进行了系统研究。
The results indic cated that Black Currant leaves were rich in many nutritive elements such as protein, amino acids and ascorbic acid which would be of great value in utilization. 结果表明,黑穗醋栗叶片含有丰富的蛋白质、氨基酸和抗坏血酸等营养素,很有利用价值。
