魷魚為台灣遠洋漁業之重要漁獲物之一，在加工過程中會產生大量的副產物或廢棄物，如內臟與墨囊 等；其中墨囊具有腥臭味，常造成使用上的困擾。因此本研究以赤魷墨囊進行一般成分分析及除臭相關試 驗，得知其水分含量約62.64%、粗蛋白28.54%、其它 (包括黑色素與碳水化合物) 7.02%、灰分1.81%、粗脂肪 0.51%；在除臭試驗方面則將烘乾之墨粉 (控制組)，分別以有機溶劑 (乙醇或正己烷)、不同濃度的鹼液以及兩 者併用處理後，再將乾燥細碎之墨粉產品進行相關除臭效果評估。在產率與總揮發性鹽基態氮 (total volatile basic nitrogen, TVBN) 方面，得知單以有機溶劑處理之產率 (39.73-42.16%) 及TVBN (160.84-165.27 mg/100 g) 與控 制組 (產率：42.69%，TVBN:171.66 mg/100 g) 相似，而在鹼液或兩者併用處理組之產率與TVBN值則隨著鹼液濃 度增加而降低，其中以高濃度鹼液 (1.0 N NaOH) 處理組之產率 (11.28%) 與TVBN (9.99 mg/100 g) 為最低。在色澤 方面，所有處理組之亮度 (L value) (14.23-19.13) 皆高於控制組 (12.94)，反之控制組之黑色度 (87.14) 為最高。最 後，經由感官品評以及上述分析結果得知，以中濃度鹼液 (0.5 N NaOH) 處理組之品評喜好度最高且除臭效果 較佳。

Squid is important catches in Taiwan's offshore fishing. However, squid viscera and ink sac in the fish processing industry are discarded or as byproducts. Among them, squid ink sac (SIS) has fish stench and is difficult to utilize. In this study, the proximate compositions analysis and deodorizing treatments of SIS from neon flying squid (Ommastrephes bartramii) were investigated. The proximate compositions in SIS were moisture: 62.64%, crude protein: 28.54%, others (melanin and carbohydrate): 7.02%, ash: 1.81% and crude fat: 0.51%. The squid ink powder products (SIP) after deodorizing treatments including no treatment (control), ethanol or hexane treatments, different alkaline concentration treatments (High, Medium, Low), or combination of ethanol or hexane solvents and alkaline solution treatments were analyzed for deodorizing evaluation. The values of yield (%) and total volatile basic nitrogen (TVBN) of deodorizing SIPs decreased with increased alkaline concentration in only alkaline treatments or combination treatments, while the high alkaline treatments (1.0 N NaOH) has the lowest yield (11.28%) and TVBN (9.99 mg/100 g). In color measurement, L* values (14.23-19.13) of all treatments were higher than that of the control (12.94), whereas the control had the highest blackness (87.14). In above-mentioned results, the SIP after medium alkaline concentration treatment (0.5 N NaOH) had the highest score of sensory acceptance and its deodorizing result was more effective.
