Natural Fatty Aldehydes for Flavours and Fragrances

将评估一种新的制造工艺，以可再生原料（种子油加工副产品流）可持续地生产天然香料和香精。这些醛类染料是香水中最重要的成分之一，也是护发产品、清洁、洗衣和个人护理产品中的芳香剂，以及加工食品中的成分。醛类还可用作润滑剂、昆虫诱捕器、药物、植物生长调节剂、抗菌剂和消毒剂。这些化合物目前是由石化原料大规模生产的。除了来自不可持续的资源之外，石化产品的化学合成还导致形成具有难闻气味的副产品，这些气味的去除成本很高，并且限制了它们的应用。由于化合物对微生物细胞的抑制性质，迄今为止还不可能用生物技术生产醛。提出的生产技术将克服这些挑战，利用一种新的酵母转化植物脂肪酸有用的醛产品。

A new manufacturing process will be evaluated for the sustainable production of natural aldehyde-based flavours and fragrances from renewable feedstocks (seed-oil processing by-product streams). These aldehdyes are among the most important ingredients used in perfumery and as aromas in hair care products, cleaning, laundry, and personal care products, and as ingredients in processed foods. Aldehydes also have applications as lubricants, insect traps, pharmaceuticals, plant growth regulators, antimicrobials and disinfectants. These compounds are currently produced at large scale from petrochemical raw materials. In addition to being derived from unsustainable resources, the chemical synthesis from petrochemicals result in the formation of by-products with unpleasant odours that are costly to remove and which limit their application. Biotechnological production of aldehydes has not been possible to date due to the inhibitory nature of the compounds to microbial cells. The proposed production technology will overcome these challenges by exploiting a novel yeast to convert plant fatty acids to useful aldehyde products.
