一.大宗漁獲機能性調理食品之開發-沖泡式速食湯調理包為期充分利用大宗漁獲、海藻和水產加工副生物資源,擬就其萃取物為原料,利用真空濃縮或噴霧乾燥技術,以添加方式試製成具有良好風味,且可以商業量產之機能性沖泡式速食濃湯調理包。就配製配方、最適製程及產品品嚐之可接受性及營養成分蛋白質、水分、鹽分及氧化物含量為指標,進一步以添加方式試製養生海藻食品或具良好風味之調理加工產品並將研究成果推廣給漁民及水產加工業者期能充分利用海藻及水產加工副產物除可提升其利用率及價值亦可增加產品市場流通性。二.水產即食調理食品之開發秋刀魚是我國重要遠洋漁獲物之一,其主要漁期為每年8至11月,94年度產量105,000公噸。秋刀魚是提供EPA和DHA的良好來源,以往曾有研究人員將之加工成罐頭、夾層魚排、調味魚乾及珍味製品。重組加工可應用於廣泛的原料上,生產高附加價值的肉製品。由於重組處理時易於定量、調味、分割、供食,加工業者可設計產品來滿足顧客的特殊需求。本研究嘗試將秋刀魚肉加工成冷凍即食醬汁餃子,以提高秋刀魚的利用價值。工作內容包括:(1)調理條件之探討:以六種熟秋刀魚碎肉(包括帶皮帶血合肉和去皮去血合肉及三種粒徑)為基質,混合不同調味料和副原料,加工成冷凍即食醬汁餃子。(2)製品品質的分析:就熟秋刀魚碎肉和上述6種製品,進行其化學性質及微生物的分析以瞭解原料和製品的品質。(3)產品接受性的評估:採用官能品評,以瞭解產品的接受性。(4)將產品儲存於-18℃,分析其化學性質與微生物的變化,以瞭解製品的儲藏壽命。

一.大宗漁獲機能性調理食品之開發-沖泡式速食湯調理包This trial attempt to extract or to use massive harvest of fisheries and seaweed or itsprocessing residue for converting those to become highly economic instant soup stockproducts with functional characteristics. The aim of this work was to find the mostsuitable drying process as well as the optimum conditions in order to convert a preparedsoup obtained from fisheries or its byproducts into a dried preparation with the bestspecific characteristics for subsequent commercialization. A vacuum or spray dryer hasbeen used to convert the liquid extract into a powdered product, the features of which(concerning fat content, protein, ash and moisture composition as well as oxidation rate)were used as the parameters considered in optimizing the drying process. Afterreconstitution, the final product was tasted by a non-trained panel to evaluate the qualityof the final soup in terms of flavor, aiming at evaluating the potential addition ofcompounds such as flavor enhancer and salt. Those results will popularize to fishermanand food factory. The prospects are to utilize the seaweed and fisheries processingresidues as possible, not only to increase its utilizing ratio and value but also to acceleratethe market circulation.二.水產即食調理食品之開發Pacific saury ( Cololabis saira) is one of the most important landings caught from deepsea. The fishing season of pacific saury is between August and November each year. Thecatches in 2005 was 105,000 mt in Taiwan. Pacific saury was good sources ofeicosapentaenoic acid and docosahexaenoic acid. The processed forms of pacific sauryincluding canned, fish cake, dried stick and dried seasoned fish slice were developed byresearchers. In this study, Pacific saury were ground then mixed with ingredients, toproduce frozen instant steamed dumplings with thick sauce, in order to elevate the valueof Pacific saury.The main works including: (1) Pretreatment condition study: After thawing, rawmaterials are divided into six types, that is two fish meat (with skin and dark muscle andwithout skin and dark muscle) and three grind size, Each minced meat mixed differentlevels season and ingredients to produce steamed dumplings with thick sauce. (2)Chemical and microbiology analysis of sample: Ground fish meat and six steameddumplings were sampling, and pH, VBN, TBA, aerobic plate count, psychrophiliccount, Coliform and E. coli were analysis to elevate its quality. (3) To compare theiracceptability with sensory evaluation, and (4) Sample were frozen at -20℃,thensampling at an interval time to analysis chemical and microbiology items. According tothe above results, to evaluate the shelf life of products.
