| Summary: | 碩士 === 國立臺灣大學 === 微生物與生化學研究所 === 96 === The research mainly measured the food contents regarding the anti-cucumber mosaic virus transgenic tomato cultivated by Asian Vegetable Research and Development Center (AVRDC). We collected the transgenic and non-transgenic tomatoes classified them into ripe and unripe groups in spring, summer and winter. Each group divided into two sub-groups with different treatments. One was measured immediately, and the other was storage under room temperature for three days before measurement. The tomato sample was preserved under -30℃ after being lyophilized and ground. The procedure inspected thirteen ingredient contents within three categories, general contents (including total solid, crude fat, crude protein, carbohydrate, total sugar, ash and crude fiber), key nutrients (including vitamin C, folate, lycopene and β-carotene) and anti-nutrients (including α-tomatine and lectin). Between transgenic and non-transgenic tomatoes, the analyzed results were not significantly different in total solid, crude fat, crude protein, ash, crude fiber, vitamin C, folate, lycopene, β-carotene, α-tomatine and lectin. Transgenic tomatoes did not change the content of the ingredients. However, the analyzed results were significantly different in carbohydrate and total sugar between non-transgenic and transgenic tomatoes. The transgenic tomato need completed for substantial equivalence for food safety. The content of the ingredients in crop may affect by environment and the difference among individuals and batches may existence. So the analyzed results were significantly different. In according to the degree of difference were lower than 20%, and unwanted effect may not occur and we need not research in the reason of the significantly different content. Besides, among key nutrients and anti-nutrients were not significantly different, the research would cooperate with the assessments of inherited traits, toxicity, allergenicity and ecological environment. We can make completely food safety assessment for transgenic tomato.
