Next the full bottle was weighed by the scale and gained the mass. The mass of the liquid, therefore, can be calculated with subtraction between the mass of the full bottle and the mass of the empty bottle. Finally its density is calculated with the equation ρ = m/v. The operation should be done at the room temperature.

D 汉译英:参考答案

Vegetables contain many different phytonutrients, many of which have antioxidative properties. Research has shown that vegetables contain other antioxidatant nutrients, in addition to the well-known vitamins C and E, and carotenoids, which significantly contribute to their total antioxidant capacity. For example, flavonoids, including compounds such as flavones, isoflavones, flavonones, anthocyanins and catechins, that are components of vegetables, have strong antioxidant capacity. There is convincing evidence that vegetables are beneficial to health and contribute to the prevention of degenerative processes. It is important to investigate the beneficial phytonutrients present in foods and the mechanisms responsible for these effects. The protection provided against diseases by vegetables has been attributed to the various antioxidants in foods. There is overwhelming evidence to indicate that free radicals cause oxidative damage to lipids, proteins, and nucleic acids. Free radicals may lie at the heart of the etiology or natural history of a number of diseases, including cancer, heart, vascular, diabetes and neurodegenerative diseases Therefore, antioxidants that can neutralize free radicals may be of central importance in the prevention of these diseases.

A. 根据文章的意思用表格中提供的词汇填空

1)Combined ohmic and conventional cooking of hamburger patties has recently

been patented as a new method of cooking. The method is based on passing electric current through the meat patties causing internal heat generation. It has been found to reduce cooking time up to half the time usually required in conventional cooking. However, the effect of applying ohmic cooking on the quality of cooked patties is not known yet. This work summarizes the experimental investigation made on the quality of hamburger patties cooked by conventional and ohmic-assisted cooking. Several properties of the patties cooked by the two methods were tested such as mechanical properties, oil and moisture contents. The results showed insignificant differences in the properties of the patties cooked by the two methods. It was concluded that ohmic heating has no effect on the quality of the cooked hamburger, which was also confirmed by non-expert tasting.

2)The free sugars and fatty acids (both free and bound) of different parts of

jackfruit (Artocarpus heterophyllus) were isolated. The sugars and fatty acids were identified and quantified by gas-liquid chromatography as their trimethylsilyl derivatives and methyl esters, respectively. Fructose, glucose and

in the bark, which is devoid of glucose. Capric, myristic, lauric, palmitic, oleic, stearic, linoleic and arachidic acids were found as major fatty acids with varying proportions in different parts of jackfruit.

3)Water extract and ethanol extract from top and body portions of field horsetail

(tsukushi) were prepared, and the antioxidative activity was investigated using four different methods. The contents of total phenolic components were richer in the ethanol extract fractions of each portion than in the water extracts. On the other hand, protein contents were much lower in ethanol extract fractions than in water extract fractions. These fractions had remarkable antioxidative activities, similar to that of 5 mM ascorbic acid. Water extracts of both portions showed high superoxide anion radical-scavenging activities. Hydroxyl radicals were effectively scavenged by ethanol extracts. Field horsetail (tsukushi) is rich in vitamins C and E. Moreover, it contains high levels of copper and zinc. These are essential elements, for superoxide dismutase to act against active oxygen species. Tsukushi is not only a health food, but is also useful in preventing various degenerative diseases.

2)The effect of storage temperature on the shelf life, weight loss, respiration rate

and ethylene formation of Hass avocado was studied. Two batches of green mature avocado fruits were stored at 10 and 20 ?C (first batch) and at 7 and 25?C (second batch). The avocado shelf lives were 22, 8,32 and 6 days under these temperature levels, respectively. Based on the data of the first assay Q10 was calculated as 2.75,with this value the predicted shelf life at 7and 25 ?C were 29.8 and 4.8 days, respectively. That meant shelf life was underestimated 7 and 20% at 7 and25 ?C, respectively. Weight loss was linear at both the storage temperatures, it was 4.3% in fruits at 20 ?C for 8 days and 3.0% at 10 ?C for 22 days. The maximum CO2 yield at 20 ?C was reached during the second day of storage, while at 10 ?C it was reached at the 17th day. The maximum ethylene production at 20 ?C was reached the second day of storage, and at 10 ?C the 6th day.

1)Coffee cherries were harvested at full maturity and treated in 50 green beans

per tree separately. The green beans were depulped using the wet processing method. After desiccation by silicagel, the beans were frozen in liquid nitrogen for 2 min before crushing in a ball mill. The fine powder was split into six samples; three were used to estimate water content and the other three underwent further analysis.

2)The estimation of total polyphenols and catechins was carried out in green tea

leaves. The ethanol extract of tea shoots was used for determination of total polyphenols and catechins. Total polyphenols were estimated by using Folin phenol Ciocalteu reagent in the presence of sodium carbonate. The absorbance of blue colour developed was measured at 700 nm. Total catechin was estimated using acidified vanillin reagent and the absorbance was measured at 500 nm. Catechin was used as standard. Total polyphenols and catechins were expressed as % on the basis of dry matter. Catechin fractions in

Effect of frying in different culinary fats on the fatty acid composition of silver carp 油炸不同烹饪脂肪对鲢鱼脂肪酸组 成的影响 姓名: 何毅 学号: 110107904 班级:食工1105班 完成日期: 2013/11/9 DOI: 10.1002/fsn3.40食品科学与营养网页292–297,2013 年7 月

关键字: ?脂肪酸组成; ?煎炸; ?油; ?鲢鱼 摘要 四种不同的油炒的影响(葵花籽油、大豆油、橄榄油、玉米油) 对鲢鱼脂肪酸的组成的 影响进行了评估。油炸后在所有评价样品的水分含量降低的鱼片脂肪含量增加。意思是饱和脂肪酸(SFA)、单不饱和脂肪酸(MUFA)、多不饱和脂肪酸(PUFA),∑ω3和∑ω6含量的原 料鱼分别是26.1 ± 0.5、52.1 ± 1.1,15.1 ± 0.6,8.9 ± 0.1 和6.1 ± 0.4%。煎炸导致脂肪酸鲢鱼脂质和油炸用的脂肪之间的交换。作为一个相互作用的结果,MUFA,PUFA,∑ω6,和PUFA / SFA的比例样品炒向日葵,大豆和玉米油,显着增加,而大量的SFA下降。煎炸了∑ω3/ω6比消极影响但橄榄油煎样品中的减少是其他样品之间最小。除了在大豆油中长链ω3-多不饱和脂肪酸含量的样品由油炸不受影响。 简介 海鲜是最丰富的ω3来源-长-多不饱和脂肪酸(LC-PUFA),主要为二十碳五烯酸(EPA,20:5ω3) 和二十二碳六烯酸(DHA,22:6ω3) 链。EPA和DHA的出现在个体发育中起着关键的作用,尤其是神经系统的发育、功能和心血管系统、免疫系统(Lauritzenet al. 2001年)的 运作。ω3和ω6多不饱和脂肪酸(PUFA)被认为是必不可少的,但由于他们不能在人体内 合成,它们必须通过饮食获得(Mahan 和Escott-Stump2005)。 水产养殖是实现发展中国家像伊朗人民的营养目标的手段之一。鲢鱼支持伊朗淡水渔业,是包括派遣内陆水产品总产量的58%左右的最重要物种。鲢鱼(鲢) 广泛应用于复合鱼文化,由于它的快速增长和抗应激、疾病和粗率的搬运。这一物种的消费对人类的营养尤其是在伊朗极为重要。 鱼通常是由伊朗人常见的食用油炸的形式。煎炸,特别深层脂肪油炸在过去的六年期间已成为最受欢迎的食物制备技术。原因是制备甚至对经验丰富更少的厨师是容易的,过程是快速的,和成品是非常美味(Gere 1982)。 复杂化学和物理所发生的变化过程中感官失败、营养价值下降和形成的化合物对健康产生不利影响的热操作结果。

大学英语专业学习计划

大学英语专业学习计划 篇一:大学英语专业规划 英语专业学习规划 英语小教093 陈盼盼 对于英语专业的学生来讲,进入大学校园后会发现专业课程交相出现,英语有关书籍种类繁杂。不由得觉得科科重要,本本经典。但是只有科学的规划,合理的时间安排才会平衡自己学习上的需求与学校授课步伐上的差异,使听说读写译五种技能得到锻炼及提高,四年之后达到熟练掌握英语这门语言工具的能力。 大一: 这一年是英语专业学习压力比较小的时候。主要开设的课程有综合英语,语音,语法,教师基本技能及如思想品德等基础课程。从中可以看到这两个学期是在为专业打基础的时候。可以做的事情首先是锻炼自己的口语,这与一般学校头一二个月的时候进行规范语音的工作相一致。平时进行语言模仿,可以选择语音质量较高的电影,歌曲,配乐诗歌,散文朗诵及演讲等材料进行逐句模仿,大段背诵的形式来锤炼语音,让人在听觉上感到一种享受。其次是对单词的积累。可以结合大学英语六级或是专业英语四级的词汇手册作为参考,加大平时背诵的单词数量,为大二下学期专业四级的考试打下基础。通过阅读有关词根词缀构词法或相关的书籍

和其它形式的材料可以帮助揭示单词内在的规律。再次是对语言基础知识的积累。多读些关于语言学习的书和杂志,报刊。如各种简装本的名著,新兴词语汇集,英语学习,二十一世纪报等,它们可以提高对语言的感性认识,增强语感,而另一个非常实用但却容易被忽略的材料是像新概念这样的经典教材,语言准确,句型精美,通过精听,模仿,背诵这三个步骤可以在短时内提高语言基础。 大二: 如果还没有完成如语音表达标准,词汇捕捉敏锐这样的对语言表层现象的掌握,那么这一年要做的事情就显得很多。除了对上述能力的加强外,这个时期对语法的把握也是比较重要的事情。不要相信他人的观点:语法不再重要,没有语法也可以交流。这样的观点看起来是十分荒谬的。英语语言高度的逻辑性就体现在其精准的语法结构上。中西方思维逻辑的判别在这里也可以窥见一斑。阅读专业的语法教材或者参加语法培训都是可取的。在第二个学期,我的学习重点会转向英语专业四级考试。但经过上面三个学期的积累和第四学期大量做题实战加之权威书籍的指点想必我一次性通过的比例应该不小。 大三: 无论是什么专业的同学在这时都应该提早做前途归化。考不考研,考什么研是英语专业学习一直疑问的问题。但不
