雞隻副產物之再利用技術

本報告將雞隻副產物再利用技術分為羽毛及其他副產物二部分進行探討。常用的羽毛再利用技術為水解技術、複合材料技術、熱裂解技術及化學修飾技術。水解技術可分解羽毛蛋白質結構，以供應生物養分或作為其他產品的原料。複合材料技術是將羽毛與其他材料結合，藉此改變材料特性，如物理性狀、隔熱性及纖維特性。熱裂解技術是將羽毛經熱化學轉化為合成氣、生物油和生物炭（羽毛炭），而羽毛炭可應用於污染吸附及電化學材料。化學修飾技術是利用化學物質改變羽毛蛋白的結構或官能基，進而改變吸附性、電化學性或溶解性。羽毛以外副產物的研究方面，高溫高壓處理技術可簡單的處理大量副產物，並應用於飼料原料。酵素水解技術能保留更多營養或機能性物質，因此產品的附加價值及應用性更佳。萃取純化研究方面，膠原蛋白萃取的文獻較豐富，可供研究人員和業者應用。而軟骨素和透明質酸提取、生物油生產和肉類加工等技術，使副產品潛在價值更加多樣化。在未來我們應該妥善應用各種再利用技術，以提升雞隻副產物再利用率並增加產品附加價值，使生態環境和產業永續發展。

The purpose of this study was to investigate the reutilization technology of chicken by-product in two parts: feathers and other by-products. Commonly used feather reutilization technologies include hydrolysis technology, composites technology, pyrolysis technology and chemical modification technology. The hydrolysis technology can decompose feather protein into biological nutrients or as raw materials for other products. The composite material technology combines feathers with other materials to change the property of the material, including the physical, thermal insulator and fiber properties. The pyrolysis technology is the thermochemical conversion of feathers into synthesis gas, bio-oil and bio-carbon (feather carbon). Feather carbon can be applied to the adsorption of pollution and electrochemical materials. The chemical modification technology uses chemical substances to change the structure or functional groups of feather proteins, thereby changing the absorptive, electrochemical, or solubility properties. With regard to the research and application of other by-products, high-temperature and high-pressure processing technology can process a large amount of by-products and then can be applied to feed materials. Enzyme hydrolysis technology can retain more nutrients or functional substances, and hence adding value and more applicability in these products. In terms of extraction and purification research, there are abundant sources of literature on collagen extraction, , which can be adopted by researchers and industry practitioners. Moreover, chondroitin sulfate and hyaluronic acid extraction, bio-oil production and meat processing technologies add more diversity to the potential value of by-products. In the future, we should properly adopt the various reutilization technologies to improve the reutilization rate of chicken by-products and increase the added-value of products, thereby to prolong the sustainable development in the ecological environment and industrial operations.
