"近年來雖然已經有許多奈米化食品出現，但其大規模量產與應用，仍然受到技術和成本上的限制。運用本土生產的大宗原料或食品加工廢棄物，再配合適當製造過程，是解決這些問題的良好對策。本計畫擬以國內每年大量產生的貝類外殼廢棄物與較為常見的海藻做為材料，探討將貝類外殼廢棄物製備成經濟價值較高的有機酸鈣、奈米鈣的方法；以及用龍鬚菜製備具有較高抗氧化活性之海藻水解物與海藻水解物−奈米鈣複合材料之方法。第一年擬使用化學反應分解廢棄貝殼，尋求降低使用化學品、提高產物之產率、以將貝殼中的鈣離子充分應用的方法。先以鹽酸溶液在不同反應條件下與貝殼中的碳酸鈣反應，再用有機酸溶液及多醣溶液與水解產物鈣離子結合，利用各種化學反應與物化性質，建立提高含有鈣離子化合物與奈米粒的水溶性與應用性，而尋求產生有機酸鈣鹽與奈米鈣之適當條件。第二年擬以國內產量最高的龍鬚菜做為原料，探討以酵素水解提高其抗氧化性的條件，並試驗以具有較高抗氧化力之水解產物與貝殼鈣離子製成海藻水解物-鈣複合奈米粒之方法。本計畫之執行有助於建立將貝類廢棄物與常見海藻轉變為高生理活性和高經濟價值產物之技術，做為國內相關產業提升其環境保護與開發新產品之技術參考。" "Nano-sized food products have become available in the market. However, technology knowhow and cost effectiveness impose a limit on their large scale production and widespread applications. Making use of plentiful domestic agricultural materials or food processing wastes, combined with a facile production process, is a good strategy to resolve these issues. This research project proposes to use the mollusk shell wastes and common algae (seaweed) as raw materials, to explore the method of making calcium salts of organic acids and making nano-sized calcium, to prepare algal hydrolysates with increased antioxidative activities, and to prepare antioxidative algal hydrolysate-calcium composite nanoparticles. In the first year, we plan to hydrolyze mollusk shell wastes by acid dissolution reactions. The method of reducing the amount of chemicals used in the process, increasing product yield, and making full use of calcium in the shell wastes will be examined. Firstly, the calcium carbonate in the shell wastes will be dissolved with hydrochloride solution under different reaction conditions. Organic acids or polysaccharide/protein solution will then be used to react with the calcium ions dissolved in the acidic solution. The optimal conditions for making different calcium salts of organic acids and nano-sized calcium will be established. In the second year, Gracilaria, the most abundant edible seaweed in Taiwan, will be used as the starting material. The enzymatic conditions for increasing the antioxidative properties of the hydrolysates will be explored. In addition, the method of making algal hydrolysate-calcium composite nanoparticles from highly antioxidative hydrolysates and shell calcium will be examined. The implementation of this project will help develop the technology for turning mollusk shell wastes and common seaweed into products with high bioactive properties and high economic value. The future results of this project can offer a useful reference to domestic industry for advancing their environmental protection and new product development technology."
