梁启超趣味主义美学

梁启超后期的美学思想是紧紧围绕着趣味得以展开的,趣味实际上是指一种审美趣味,它与日常趣味的最大不同在于它的非功利性,梁启超正是从这一点出发,作出了其独具特色的具有现代意义的美学建构.

Substance P-like immunoreactive fibers in the frog taste organs

Summary In the frog tongue, substance P(SP)-like immunoreactive fibers were consistently present in each fungiform papilla, which contained the gustatory apparatus. Numerous SP-like immunoreactive fibers were usually distributed in the periphery of the gustatory disc and formed a varicose meshwork among the ciliated cells encircling the gustatory disc. SP-like immunoreactive fibers were rarely evident inside the gustatory disc. The role of SP-containing fibers in the frog taste organ was discussed.     

The development of taste transduction and taste chip technology

Taste is one of important sensations. The primary taste sensations commonly are categorized as sweet, acid, bitter, salty and umami, of which various tastes are composed. The sensation of taste is initiated by the interaction of tas- tants with receptors and ion channels in the apical micro- villi of taste receptor cells (TRCs) when some sapid molecules (tastants) dissolve in saliva. Subsequently, through a cellular signaling pathway (TRC depolarization and Ca2+ release) gustatory signals a…     

咸鲜味、糖醋味菜肴最佳配比与作用机理的研究

通过正交试验对咸鲜菜肴、糖醋菜肴进行感官检验，利用模糊关系法对检验结果进行处理，结果表明：对于咸鲜菜肴，最佳配比为盐∶味素＝３．２５∶１，食用温度为１０℃（凉拌），糖醋味菜肴的最佳配比为盐∶醋∶糖＝１∶５∶１５，食用温度为４０℃。     

Electrical responses to taste chemicals across the dorsal epithelium of bullfrog tongue

Summary Stimulation of the bullfrog tongue with taste chemicals produced a slow change in transepithelial potential difference across the dorsal epithelium. The potential profile was in many respects similar to that of the intracellularly recorded potential changes in taste cells and to the activity of taste fibers in frogs.

五峰夏秋茶主要呈味成分分析研究

为了研究五峰春茶、夏茶和秋茶的主要呈味成分和品质的差异, 以五峰春茶、夏茶和秋茶为样品,利用重量法对五峰春茶、夏茶和秋茶的水分、水浸出物进行测定和比较;利用紫外分光光度法和高效液相色谱法(High Performance Liquid Chromatography, HPLC)测定样品的主要呈味成分,包括茶多酚、儿茶素、表没食子儿茶素没食子酸酯(Epigallocatechin gallate, EGCG)、咖啡因和氨基酸含量.研究结果表明,五峰春茶、夏茶和秋茶的主要呈味成分存在差异.茶多酚、儿茶素、EGCG含量：春茶 < 夏茶 < 秋茶;咖啡因、茶氨酸、总氨基酸含量：春茶 > 夏茶 > 秋茶.不同季节的茶叶呈味成分成分之间存在较大差异,可能是导致五峰夏秋茶苦涩味偏重的主要原因.     

酱油风味与功能性成分研究进展

酱油作为中国传统发酵调味品,其风味是重要的质量指标,功能活性也受到人们的关注。酱油的风味和功能成分复杂,如何全面地解析构成风味和功能特性的挥发性及非挥发性化合物,并对其进行有效的调控一直是调味品行业的研究热点。据相关研究报道,酱油中香气活性物质有202种,按气味类型可分为酸香、醇香、麦芽香、花香和果香、焦糖香、烟熏香、蔬菜香等,不同香气的化合物以一定比例组合形成了酱油浓郁的酱香;酱油中非挥发性物质有230种,带给酱油酸味、甜味、苦味、咸味、鲜味和浓厚味的综合味感,其中咸味、鲜味较为突出;酱油中已报道的生理功能活性物质约30种,在抗氧化、抗癌、降血压、降尿酸等方面具有一定的生理功能作用。详细介绍了酱油风味检测技术的更迭和优缺点,按照香气特征、滋味特征和功能特性分类介绍了其关键活性物质基础,评述了技术和理论的发展方向,旨在为酱油及传统发酵行业的高品质发展提供借鉴。
