摘要

本研究以鮪魚加工衍生的蒸煮液，進行精製、蛋白酵素水解、濃縮與製作噴霧乾燥微膠囊粉末，開發成具水產風味的調味粉末製品。由於粉末製品有方便性、即溶性與可長期儲藏的特性，因此許多食品調味品以粉末形式呈現。經初步測試後，18種微膠囊造粒的條件（3種噴霧乾燥溫度、2種水解物與阿拉伯膠調配比例與3種阿拉伯膠濃度等＝3×2×3）與粉末性質間的關係（如粉粒的含水率、水活性、密度、粉粒流動性、溶解性、色澤與粒徑分布等）在實驗中被探討。較優良微膠囊產品進行電子顯微鏡觀察造粒情形，並進行儲存條件測試，以開發出最佳製程的微膠囊粉末製品。從本研究結果發現，精製濃縮的鮪魚蒸煮液水解物與15%阿拉伯膠進行噴霧乾燥，所得產品經由整體品評（味覺、視覺與嗅覺分析）評價最好，尤其以噴霧乾燥溫度160℃，蒸煮濃縮液與15%阿拉伯膠以1:5比例混合均質後進行微膠囊造粒，此產品整體品評為最佳，其亦有高溶解度、低含水率以及優良之儲存特性。

Since powdered products are convenient, instant and long-term storage of the features, many seasoning products are present in form of powder. In this study, tuna cooking juice derived from can processing was refined, hydrolyzed by proteinase, condensed, and spray-dried for production of microencapsulated powder. It is desired to develop a seasoning powder of with seafood flavor. After initial testing, 18 kinds of microencapsulation conditions (three kinds of spray drying temperature, two gum Arabic/cooking liquid hydrolysate ratios, and three kinds of concentrations of gum Arabic solutions; 3 × 2 × 3= 18) were developed and the properties of the microencapsulated powder products (including moisture content, water activity, density, powder flow, solubility, color, and size distribution, etc.) are studied. Excellent microcapsules were observed by scanning electron microscopy and tested for their optimum storage conditions. Through whole tasting test (taste, sight and smell), spray dried microencapsules made from refined, hydrolyzed and concentrated tuna cooking juice mixed with 15% gum Arabic had higher evaluation scores. Especially the microencapsulated power produced with spray drying temperature of 160℃ and cooking juice concentrate/ 15% Arabic gum ratio of 1:5 had high solubility, low water content and excellent storage characteristics.
