| 1 | 金樱子—西瓜混合保健果汁饮料的研究显示文摘以金樱子果和西瓜皮为主要原料,经取汁、调配、过滤、杀菌等加工工序,研制出了混合透明的营养保健型果汁饮料。研究表明,用明胶能有效除去金樱子果汁中的多酚物质,防止了产品的浑浊;适量添加西瓜汁和柠檬酸,能有效地抑制金樱子汁的涩味,提高了产品的适口性并确定了产品的最佳生产配方。 | Yu Yougui Shaoyang Higher Training School\ Shaoyang\ 422004 | 1998 | 饮料工业1998，1，6： | 2 |
| 2 | Age Assignment of the Lycoptera- bearing Bed显示文摘In the Yanliao area, the occurrence of the Nestoria-Keratestheria fauna and the Eoparacypris- Luanpingella-Darwinula assemblage in the Dabeigou Formation s.s., a Rb-Sr isochron age of 145.2 Ma for the Baiqi Formation and a complete stratigraphic sequence-all this proves that the Lycoptera-bearing bed overlies the Upper Jurassic. The Jehol fauna comprises the primitive Trigonioidids fauna, Eosestheria fauna, Lycoptera fauna et al., and their own laws of evolution expound that they belong to Cretaceous faunas. The associations of Eosestheria with Yanjiestheria, Lycoptera with Eosestheria, and Kuntulunia with Yanjiestheria as well as the occurrence of early angiosperms and sporo - pollen in the Fuxin Formation and its equivalents also demonstrate that the Lycoptera-bearing, bed should be assigned to the Cretaceous. The confirmation of the existence of Aucellina in the Jixi Group and the correlation of Trigonioidids and Cypridids with those in the equivalent strata of Japan and Western Europe have also | Li Peixian, Su Deying, Li Yougui and Yu JingxianInstitute of Geology, Chinese Academy of Geological Sciences, Beijing | 1994 | Acta Geologica Sinica(English Edition)1994，68，3： | 1 |
| 3 | Distribution patterns of tree species in an evergreen broadleaved forest in eastern China显示文摘Ecological assembly rules in evergreen broad-leaved forest are far from clear understanding.Spatial dispersion of individuals in a species is central in ecological theory.We analyzed the spatial patterns as well as associations between adult and juvenile of each tree species in a 5-ha subtropical evergreen broad-leaved forest plot in eastern China.Out of the 74 species occurring with more than 10 individuals,88.4%of these species are aggregated.Most of them are aggregated from small to large scales.Spatial distributions of some species corre-spond with topography.Many bad dispersed species in the Baishanzu exhibit a highly aggregated distribution at small scales.These suggest that environmental heterogeneity and/or dispersal limitation may be the most important mechanisms that control the distribution patterns of these species.Our observations of the aggregations of abundant species basically support the hypothesis that dispersal limitation decreases as the number of reproductive trees increases.The rest species are randomly distributed,with less than 10 individuals.For most common species,spatial aggregation is weaker in larger diameter classes,and the distance between adults is larger than that between juveniles and adults,suggesting that density-dependence works on loosing aggregation and excluding conspecific juveniles away from adult trees.However,the density-dependent effect is not strong enough to eliminate all seedlings near adult trees and to result in a regular distribution of trees;thus the density dependence is usually masked by the refuge effect. | Zhengrong LUO Bingyang DING Xiangcheng MI Jiuhua YU Yougui WU | 2009 | Frontiers in Biology2009，4，4： | 1 |
| 4 | Identifi cation and characterization of a novel tetrapeptide from enzymatic hydrolysates of Baijiu byproduct显示文摘In order to prepare angiotensin I-converting enzyme(ACE)inhibitory peptides,distilled spent grains of Chinese strong-flavor Baijiu were hydrolyzed by alcalase followed by papain under optimized conditions.A superior ACE inhibitory peptide was separated and purifi ed by ultrafi ltration and high-performance liquid chromatography(HPLC),and its amino acid sequence was further identified as Gln-Gly-Val-Pro(QGVP)by electrospray mass spectrometry(ESI-MS).QGVP formed 6 hydrogen bonds with the active site of ACE,which is responsible for reducingα-helix structure content of ACE causing subsequent inactivation.M oreover,it showed no significant cytotoxicity toward human umbilical vein endothelial cells(HUVECs),a nd signifi cantly i nduced phosphorylation of endothelial nitric oxide synthase(p-e NOS)and decreased endothelin 1(END1)expression in angiotensin I(Ang I)-treated HUVECs,demonstrating the potential antihypertensive effect.The peptide QGVP hydrolyzed from distilled spent grain proteins of Chinese strong-fl avor Baijiu was expected to be used as a food ingredient to prevent or co-treat hypertension with other chemical drugs. | Qiang Wu Changqing Zhong Guirong Zeng Xu Zhang Liping Xiang Chang Wan Yougui Yu | 2022 | Food Science and Human Wellness2022，11，6： | 0 |
