چکیده
ウンシュウミカンの“貯蔵臭”による品質低下が問題とされている.貯蔵臭とは“長期貯蔵”されたカンキツ類から感じる食品異臭(オフフレーバー)とされているが,その詳細は明らかとなっていない.本研究では貯蔵臭をもつウンシュウミカンの選別法開発に向け,嗅覚官能評価によって貯蔵臭を定義すること,貯蔵臭物質を同定することを目的とした.常温および低温で長期貯蔵されたウンシュウミカン可食部を対象として嗅覚官能評価に供試した結果,常温区(25°C)と比較して低温区(4°C)において“草のようなにおい”が強まったことから,その印象を貯蔵臭として定義した.倉庫内部の臭気を評価したところ“草のような”においは感知できず,外部からの臭気付着は無いと考えられた.続いて“草のようなにおい”を対象として“におい嗅ぎガスクロマトグラフィー(GC-O)”をもちいて物質同定に取り組んだところ,p-シメネンが貯蔵臭物質として同定された.

Heavy flavor production off protons and in a nuclear environment
These lectures present an overview of the current status of the QCD based phenomenology for open and hidden heavy flavor production at high energies. A unified description based on the light-cone color-dipole approach is employed in all cases. A good agreement with available data is achieved without fitting to the data to be explained, and nontrivial predictions for future experiments are made....
متن کاملGluon Shadowing in Heavy Flavor Production off Nuclei
Gluon shadowing which is the main source of nuclear effects for production of heavy flavored hadrons, remains unknown. We develop a light-cone dipole approach aiming at simplifying the calculations of nuclear shadowing for heavy flavor production, as well as the cross section which does not need next-to-leading and higher order corrections. A substantial process dependence of gluon shadowing is...
متن کاملStudy of precursors responsible for off-flavor formation during storage of potato flakes.
Off-flavors frequently appear during the storage of potato flakes. Volatile profile analysis performed by solid-phase microextraction-gas chromatography-mass spectrometry revealed that hexanal is the main compound that appears during the storage period. Hexanal may be a degradation product of linoleic acid formed through linoleic acid hydroperoxide cleavage. Profiles of hexanal precursors were ...
متن کاملFlavor without Flavor Symmetry
Non-trivial patterns of quark and lepton masses and mixings can arise without there being any underlying flavor symmetry that distinguishes among the three families. Two realistic examples are given.
