Six optically active (Z)-7-decen-4-olide derivatives (1a-1f) were synthesized in 99% enantiomeric excess using diastereomeric resolution. The odour properties of the racemic and optically active 1a-1f were evaluated in terms of their orthonasal aromas. All of the stereoisomers had different odour characteristics and thresholds. Decen-4-olides (1a-1c) had a strong fruity note, whereas undecen-4-olide

Nanoarchitectonics and Catalytic Performance of Au-Pd Nanoflowers Supported on Fe2O3 J. Oleo Sci. (IF 1.5) Pub Date : 2023-11-02 Yoshiro Imura, Masami Tanaka, Asuka Kasuga, Ryota Akiyama, Daisuke Ogawa, Hirokazu Sugimori, Clara Morita-Imura, Takeshi Kawai
Supported anisotropic bimetallic nanocrystals are attractive owing to their potential for novel catalytic applications. Au-Pd nanocrystals are expected to have higher catalytic activity for alcohol oxidation than Au nanocrystals. However, only a few studies have reported the application of anisotropic Au-Pd nanocrystals as alcohol-oxidation nanocatalysts. Support materials such as Al2O3 and Fe2O3 influence

Physicochemical Properties of Beeswax: The Effects of Cooking Methods and Harvesting Positions J. Oleo Sci. (IF 1.5) Pub Date : 2023-10-03 Huong Dinh Tran, Hoang Minh Le, Cang Huynh Mai, Viet Bao Nguyen
Beeswax is an important agricultural product in many developing countries and its quality can be affected by various factors of the harvesting and processing. This study compared the extraction yield as well as physicochemical properties of beeswax melted by different methods (solar energy and conventional method) and collected at different positions (surface of honeycomb and the old nest cakes). Obtained

Research Progress of Nervonic Acid Biosynthesis J. Oleo Sci. (IF 1.5) Pub Date : 2023-10-03 Cheng Ling, Feng Li, Jiangyuan Zhao, Mengliang Wen, Xiulin Han
Nervonic acid (NA) is a very-long-chain monounsaturated fatty acid with great application values. It plays a vital role in the development of brain nervous system and the treatment of neurological diseases, so it has attracted much attention from all walks of life. Although NA has a wide range of sources, its current acquisition methods are still mainly relied on chemical synthesis and plant extraction

Oscillations in Dynamic Surface Tension of Cationic-nonionic Binary Surfactant Aqueous Solutions J. Oleo Sci. (IF 1.5) Pub Date : 2023-10-03 Hiroki Matsubara, Xiaolei Xu, Akira Bochi, Makoto Aratono
In this work, the adsorption dynamics of mixed aqueous solutions of tetraethyleneglycol monoocthyl ether (C8E4) - dodecyltrimethylammonium bromide (DTAB) were studied using sessile bubble surface tensiometry. When C8E4 was added to the DTAB solution, the dynamic surface tension exhibited a unique oscillation decay pattern. In contrast, the addition of DTAB to the C8E4 solution resulted in a simple
