帮朋友求助，翻译软件太烂了，高氯酸－－Gao chloric acid，晕！ 摘 要 目的 考察不同的配方中乳酸菌对无机硒生物的转化能力 方法 通过改变富硒酸奶的处方条件，例如接种量、硒的浓度、其它配料等，考察乳酸菌对无机硒的利用能力。将培养好的样品进行细胞离心，离心后的量取上清液，以此得到残留的无机硒，再用总的加加硒量减去，得到有机硒的含量。用浓硫酸-高氯酸的消化体系消化样品后准确测定无机硒，利用紫外分光光度法，于335nm处测量吸光度,在标准曲线上查出硒含量，计算无机硒的利用率和转化率。 结果 利用透析的方法，将无机硒和有机硒分开。其总硒含量达0.4μg/mL,转化硒为0.323μg/mL,转化率为92.43%。 结论 乳酸菌接种量7%,加糖量8%,在40℃发酵可制得口感和组织状态较佳的酸乳制品,与普通酸乳相比感官和理化指标均无差别。有机硒含量达到0.323μg/mL,成人每日饮用200~500 mL充分满足对硒的需求。 关键词: 无机硒 有机硒 加硒条件 乳酸菌 生物转化 利用率 转化率 [ Last edited by 小晓春 on 2007-6-16 at 04:56 ] |

这是一个朋友翻的，请大家改改： ABSTRACT Objective To investigate the different prescription Lactobacillus of inorganic selenium into the biological capacity by changing the method Se prescription of yogurt pieces, such as the amount of inoculation, the concentration of selenium, and other ingredients, Lactobacillus inspection of inorganic selenium in capacity utilization. Will cultivate good sample cell centrifugation, the centrifuge obtained from the supernatant, this is the residual inorganic selenium, The overall increase and then subtracting the selenium, organic selenium content. H2SO4 - perchloric acid digestion of samples after digestion system accurately measured inorganic selenium, UV spectrophotometry, at 335 nm absorbance measurements, the standard curve discovered selenium content in terms of inorganic selenium utilization and conversion rate. The results of the use of dialysis method, inorganic and organic Se Se separately. The total selenium content of 0 .4μg/mL into 0.323μg/mL for selenium, the conversion rate of 92.43%. Conclusion Lactobacillus inoculum 7% and 8% sugar. at 40 ° C can be obtained by fermenting and taste better state of the Organization of acid dairy products, Compared with ordinary yoghurt sensory and physical-chemical indicators of discrimination. Organic selenium content reaches 0 .323μg/mL. Adult daily consumption of 200 ~ 500 mL of selenium fully meet the demand. Keywords : inorganic selenium organic selenium and selenium conditions Lactobacillus Bioconversion utilization rate conversion |

以下翻译不知行不？ Abstract Objective：Look at different formulations of lactobacillus inorganic selenium into the biological capacity 。 Methods：Se yogurt by changing the prescription conditions, such as inoculation, the concentration of selenium, and other ingredients. Lactobacillus inspection of the use of inorganic selenium capacity. Will cultivate good sample cell centrifugation, the centrifuge obtained from the supernatant, this is the residual inorganic selenium, The overall increase and then subtracting the selenium, organic selenium content. H2SO4 - perchloric acid digestion of samples after digestion system accurately measured inorganic selenium, UV spectrophotometry, at 335 nm absorbance measurements, the standard curve discovered selenium content in terms of inorganic selenium utilization and conversion rate。 Results：Use dialysis method, inorganic and organic Se Se separately. The total selenium content of 0 .4μg/mL into 0.323μg/mL for selenium, the conversion rate of 92.43%。 Conclusion：Lactobacillus inoculum 7%, 8% sugar, 40 ℃ and texture can be obtained and state organizations better acid dairy products, Compared with ordinary yoghurt sensory and physical-chemical indicators of discrimination. Organic selenium content reaches 0 .323μg/mL. Adult daily consumption of 200 ~ 500 mL of selenium fully meet the demand。 Keywords ：Inorganic selenium、Organic selenium、Se conditions、Lactobacillus、Bioconversion、Utilization、Conversion。 |
