请高手帮忙翻译个句子,是关于牡蛎高压处理的,十分感谢!主要是and these were attributed前面的部分.
Sensory analysis revealed that oysters mainly have green/sulfur/crustacean, mushroom/citrus-like, and marine/cucumber aroma notes and these were attributed to dimethyl sulfide, 1-penten-3-one, hexanal, (2,4)-E,E-heptadienal, 1-octen-3-one, 1-octen-3-ol, 6-methyl-5-hepten-3-one, octanal, (E,Z)-2,6-nonadienal, (E)-2-octenal, and decanal.
翻译得好,另有悬赏!
希望翻译能精准点，不要直接用在线翻译工具。另外再问几个有机化学的专业名词：
alkenals;alkadienals;cardboardy;painty;heptenal.
谢谢！
