<正> 大约公元前900年,一位阿拉伯医生Rhazes第一次在文献中提到咖啡。最初,咖啡是一种食物,继而用于酿酒、入药,用作饮料可追溯到700年前。如今它是世界上最普遍的兴奋刺激饮料之一。咖啡是由一种属于茜草科的热带植物的成熟果加工制作而成的。咖啡树的主要品种有小粒种咖啡(Coffea arabica)、中粒种咖啡(C.robusta)和大粒种咖啡(C.liberica),而小粒种咖啡是主要栽培种。咖啡炒制加工过程概述如图1。 相似文献

Coffee consumption is worldwide spread with few side effects. Interestingly, coffee intake has been inversely related to the serum enzyme activities gamma-glutamyltransferase, and alanine aminotransferase in studies performed in various countries. In addition, epidemiological results, taken together, indicate that coffee consumption is inversely related with hepatic cirrhosis; however, they cannot demonstrate a causative role of coffee with prevention of liver injury. Animal models and cell culture studies indicate that kahweol, diterpenes and cafestol (some coffee compounds) can function as blocking agents by modulating multiple enzymes involved in carcinogenic detoxification; these molecules also alter the xenotoxic metabolism by inducing the enzymes glutathione-S-transferase and inhibiting N-acetyltransferase. Drinking coffee has been associated with reduced risk of hepatic injury and cirrhosis, a major pathogenic step in the process of hepatocarcinogenesis, thus, the benefit that produces coffee consumption on hepatic cancer may be attributed to its inverse relation with cirrhosis, although allowance for clinical history of cirrhosis did not completely account for the inverse association. Therefore, it seems to be a continuum of the beneficial effect of coffee consumption on liver enzymes, cirrhosis and hepatocellular carcinoma. At present, it seems reasonable to propose experiments with animal models of liver damage and to test the effect of coffee, and/or isolated compounds of this beverage, not only to evaluate the possible causative role of coffee but also its action mechanism. Clinical prospective double blind studies are also needed. 相似文献

Abstract The agroforestry program of the AMISCONDE Initiative was implemented in 13 buffer zone communities of La Amistad Biosphere Reserve. This program introduced citrus (Citrus spp.) and promoted the widespread inclusion of poró (Erythrina poeppigiana) shade trees, ground story vegetation, and soil conservation techniques to the local cultivation of coffee (Coffea arabica var caturra). This program sought long-term socioeconomic and ecological health in these buffer zone communities through conservation and development projects such as coffee agroforestry systems. This paper examines the ecological and socioeconomic benefits of two introduced coffee agroforestry systems: coffee-poró and coffee-citrus. The project has decreased agrochemical inputs, integrated multi-strata vegetation, and implemented soil conservation techniques such as vetiver grass, cover crops, terraces, water channeling, and shade trees in an effort to sustainably manage coffee production on the steep buffer zone slopes. The agroforestry project of the AMISCONDE Initiative has likely improved the production of coffee ecologically and economically. However, new specialty markets should be explored to increase economic and ecological gains. Organic and fair trade coffee niche markets are suggested as alternatives for meeting the long-term AMISCONDE objectives of community development and conservation. 相似文献

Transpiration of Arabica Coffee and Associated Shade Tree Species in Sub-optimal, Low-altitude Conditions of Costa Rica 总被引:3,自引:0,他引:3
Sap flows of coffee (Coffea arabica L. cv ‘Costa Rica 95’) and associated timber trees (Eucalyptus deglupta or Terminalia ivorensis) or leguminous tree (Erythrina poeppigiana) were measured simultaneously during 12 months in 4-year-old coffee agroforestry systems in sub-optimal ecological conditions
of Costa Rica. In the wet period, coffee and shade tree transpiration followed the daily patterns of photosynthetic photon
flux density (PPFD) and reference evapotranspiration (ETo) while their transpiration was restricted at higher air VPD values
(>1.5 kPa) registered during the dry period. Coffee transpired more per unit leaf area in full sun than under shade, an indication
of higher environmental coffee stress in non shaded conditions. Nonetheless, coffee daily water consumption per hectare was
generally higher under shade than in full sun due higher vegetative growth of shade-grown coffee plants. Minimum and maximum
daily transpiration were 0.74 and 4.08 mm for coffee, 0.35 and 1.06 mm for E. deglupta, 0.70 and 2.10 mm for T. ivorensis and 0.13 and 0.79 mm for E. poeppigiana. Estimation of the annual combined water transpiration by coffee and shade trees was 20–250% higher than that of coffee grown
in full sun. Nevertheless, there was no evidence that water use by associated trees decreased soil water availability for
coffee and hence limited coffee transpiration in the dry season due to its relatively short length (3 months) and the high
annual rainfall (over 3100 mm). In the sub-optimal, low altitude conditions of this experiment, E. deglupta was the optimum shade species as it maintained a more constant shade level throughout the year and ensured a better protection
to coffee underneath than T. ivorensis and E. poeppigiana which underwent a complete defoliation during the adverse meteorological conditions of the dry period. 相似文献
