1热处理对直链淀粉扩增、蜡性及正常玉米淀粉物理性质和酶解率的影响显示文摘对直链淀粉扩增(ae)、蜡性(wx)及正常玉米淀粉经热处理(autoclaving)后,其物理性质和酶解率的变化进行研究。淀粉经热处理后,除蜡性淀粉其峰值粘度增加外,所有淀粉的峰值粘度降低,且糊化温度提高。热处理增加扩增淀粉的热焓(ΔH),但降低蜡性淀粉的ΔH;同时对正常玉米淀粉的ΔH几乎无影响。热处理使蜡性和正常玉米淀粉的硬度和粘结力增加,但使扩增淀粉的硬度和粘结力降低;同时使所有淀粉的弹性降低。热处理后除蜡性淀粉其溶解率提高外,所有淀粉的膨胀率和溶解率降低。热处理降低所有淀粉的透光率和酶解率。刘惠君 Lawrence Ramsden Harold Corke 1998中国粮油学报1998,13,4:17
2芋头在加工食品中的应用显示文摘芋头是天南星科中最重要的可食品种,具有悠久的栽培历史。2,000多年来,亚洲、非洲和波利尼西亚等地区的人,一直把它当作一种农作物。芋头遍布于热带地区,现在栽培的品种可能有数千种,大致可归纳为一个种属两个亚种,即生长1个中央大块茎的“dasheen”型和生长成很多小球茎的“eddoe”型。 芋头是一种淀粉质块茎,叶子简单宽阔而叶柄长。尽管很多芋头品种的外表、风味和质地均不一致,但其某些特征仍是相似的,如外表多毛。蒋高松 Lawrence Ramsden Harold Corke 1998中国食品工业1998,,12:10
3Stigmatic exudate in the Annonaceae:Pollinator reward,pollen germination medium or extragynoecial compitum?显示文摘Although 'dry-type' stigmas are widely regarded as ancestral in angiosperms, the early-divergent family Annonaceae has copious stigmatic exudate. We evaluate three putative functions for this exudate: as a nutritive reward for pollinators; as a pollen germination medium; and as an extragynoecial compitum that enables pollen tube growth between carpels. Stigmatic exudate is fructose dominated(72.2%), but with high levels of glucose and sucrose; the dominance of hexose sugars and the diversity of amino acids observed, including many that are essential for insects, support a nutritive role for pollinators. Sugar concentration in pre-receptive flowers is high(28.2%), falling during the peak period of stigmatic receptivity(17.4%), and then rising again toward the end of the pistillate phase(32.9%). Pollen germination was highest in sugar concentrations <20%. Sugar concentrations during the peak pistillate phase therefore provide optimal osmolarity for pollen hydration and germination; subsequent changes in sugar concentration during anthesis reinforce protogyny(in which carpels mature before stamens), enabling the retention of concentrated exudate into the staminate phase as a pollinator food reward without the possibility of pollen germination. Intercarpellary growth of pollen tubes was confirmed: the exudate therefore also functions as a suprastylar extragynoecial compitum, overcoming the limitations of apocarpy.Jenny Y.Y.Lau Chun-Chiu Pang Lawrence Ramsden Richard M.K.Saunders 2017Journal of Integrative Plant Biology2017,59,12:3
