「民以食為天!」
歷史的發展伴隨著糧食資源豐富的區域,古中國流傳至今的這句話說明了「吃」是多麼重要的一件事,求得三餐溫飽遂成為那個時代的人的生活中心。但相較於遠古時代,現今的人們較少為了「吃飽」而煩惱,而自此衍生而出的是「不只吃飽,更要吃好」,開始追求大魚大肉、滿漢全席;開始改變烹調方法,煎煮炒炸、煙燻、醃製;開始利用食品加工的技術為食物加上各式各樣的顏色與味道。 導致在食品加工業蓬勃發展的現代,「吃」這件事變成了一個疑問詞,重視養生的我們開始對吃進去的東西產生疑問,「我吃進去的食物有哪些成分?」、「食品添加物是什麼?」、「食品的檢驗標準是怎麼訂定的?」、「檢驗超標會對人體產生什麼危害?」,這些各式各樣對於吃的疑問加上媒體的渲染下,對「吃」的恐懼油然而生。 「吃得飽不如吃得巧!」 對應這些問題,其實科學家們發展出了多套嚴謹的毒理機制來評斷食品安全性。而我們將在本課程中以深入淺出的概念將毒理學應用在食品安全評估,介紹這些機制運作的方法和實際應用的例子,希望使同學了解看到擺在架上的食品,其背後許多不為人知的故事,並在面對層出不窮的食安問題時,能具有相當的基本概念,與對這些問題的思辨能力。
本週課程會先將接下來六週內容做一次性的概述,認識可能造成食品危害的途徑。學習毒理學之基本概念如ADME、ADI,與如何將其應用於食品檢驗標準的方法。修完此週後應會對檢驗標準的訂定有一定認識,且能藉由自身判斷新聞中常見的檢驗超標或殘留所代表的意義。

「天然就是健康的嗎?」本週將介紹天然食物中所不為人知的一面,包含天然食物複雜的成分中可能會具有毒性的物質,如動植物毒素、黴菌毒素與蕈菇毒素,和非毒素所造成的不適反應,如食物過敏反應。最後對輻射污染與基改食品兩個眾所關注的議題進行討論。

介紹過了食物在上游處理過程中可能造成的食安危害,這週要介紹的是食物在烹煮過程中可能產生的有害物質,包含燒烤產生的多環芳香族碳氫化合物、油炸所產生的丙烯醯胺,與香腸中的亞硝酸鹽會造成什麼危害?最後介紹了由餐具釋放的有毒物質。希望在學完本週課程後可以學會如何在食物的烹煮過程中避開或減少攝取這些毒性物質。

食品添加物在近期常常被提出討論,過量添加與違法添加的事件也時有耳聞,造成社會大眾恐慌。成分表上複雜的添加物名詞,與多種不知名的添加物是否讓你不知所措?揪竟如此多種的食品添加物吃進肚子裡會對人體造成什麼為害?在本週將對現在市面上常見的食品添加物進行介紹,包含防腐劑、保色劑、乳化劑等等。

熱量也具有毒性嗎?如果是的話,這也許是另一個能說服自己開始減少熱量攝取的理由了!本週將從基本的營養單位:醣類、蛋白質、脂肪開始講起,介紹他們在人體內的代謝過程。與介紹熱量、肥胖與疾病三者間的關係。小提醒:別忘了期末作業與期末總複習考試喔!

We asked all learners to give feedback on our instructors based on the quality of their teaching style.
We firmly believe that open access to learning is a powerful socioeconomic equalizer. NTU is especially delighted to join other world-class universities on Coursera and to offer quality university courses to the Chinese-speaking population. We hope to transform the rich rewards of learning from a limited commodity to an experience available to all.

偏硬,教材反覆看才能達到100%通過(只看一兩次不太可能全對),教授講課算活潑期中榮譽作業海報很好做,但期末榮譽作業滿花時間看資料的

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
