all the results are showed as following : 1 . thiolysis and unthiolysis hplc together will be better to quantify the main apple polyphenolics 硫解和非硫解hplc相結(jié)合能較全面地定量分析蘋(píng)果果實(shí)中主要多酚化合物種類和含量。
there were different kinds of apple polyphenolics with different varieties of gala and golden . as it is known, the anthocyanidin is only in gala skin but not in golden skin . it is found in this study that there has quercetin in golden pulp but not be detected in gala pulp 嘎拉和金冠中多酚化合物種類不同,已知嘎拉果皮中含有花青素-山越橘苷,而金冠中沒(méi)有;本實(shí)驗(yàn)發(fā)現(xiàn)金冠果肉中含有槲皮苷,而嘎拉果肉中沒(méi)有檢測(cè)到。
5 . the total content of all determined polyphenolics in golden changes less than 93 that in gala . considering the stable of the their content and the costing for storing the apples, golden apples would be stored in cold storage, air condition and ultro-lower storage for 84 days, 157 days and 182 days, respectively 金冠果實(shí)中多酚在貯藏過(guò)程中變化幅度小于嘎拉:從總酚含量穩(wěn)定性和蘋(píng)果貯藏成本考慮,金冠能夠普通冷藏到84天、氣調(diào)到157天、超低氧貯藏到182天;嘎拉能普通冷藏到55天、氣調(diào)貯藏107天、超低氧貯藏161天。
from 24th august of 2001 to 8th april of 2002, gala ( malus cv . gala ) and golden ( m . cv . golden delicious ), stored with three different models of cold storage, air condition and ultro-lower oxygen, were kindly provided in different sale time by inter-profession technique center of fruit and vegetable of france . the fruits were cut into three parts of the skin, pulp and core according to the human edible habit . the apple polyphenolics in the skin and pulp were determined by thiolysis hplc and unthiolysis hplc in institut national de la recherche agronomique, laboratoire de recherches cidricoles 為建立能全面測(cè)定蘋(píng)果果實(shí)多酚的hplc方法,同時(shí)為蘋(píng)果營(yíng)養(yǎng)標(biāo)簽的制定提供不同銷(xiāo)售時(shí)期蘋(píng)果多酚含量的依據(jù),指導(dǎo)貯藏方式和時(shí)期的選擇,明確的消費(fèi)信息,自2001年8月24日至2002年5月15日,由法國(guó)果蔬跨行業(yè)技術(shù)中心提供普通冷藏、氣調(diào)和超低氧方式下,不同銷(xiāo)售時(shí)期的嘎拉(malus,cv.gala)和金冠(m.cv.goldendelicious)為試材,根據(jù)蘋(píng)果食用習(xí)慣將果實(shí)分為果皮、果肉和果心二部分,利用硫解hplc和非硫解hplc定量分析世界主栽品種金冠和嘎拉果皮和果肉多酚物質(zhì)含量,并對(duì)不同貯藏方式下和同一貯藏方式下的不同商業(yè)貯藏時(shí)期多酚物質(zhì)含量作了比較。
