Teng, Xiuxiu;Zhang, Min;Bhandari, Bhesh;Liu, Yaping research published 《 Effect of microwave vacuum drying with different auxiliary materials on hygroscopicity and flowability of chicken powder》, the research content is summarized as follows. Spray drying (SD) of chicken suspension by the addition of maltodextrin (MD) is a traditional method of producing chicken powder in most of Asia. Hygroscopicity of the powder is the biggest disadvantage of this method. A new method was designed by using microwave vacuum drying (MVD) with MD or gum Arabic (GA) to produce lower hygroscopic chicken powder. Hygroscopic curves and low-field NMR (LF-NMR) spectroscopy were used as the criteria to evaluate hygroscopicity of samples. The results showed that MVD-MD possessed the lowest moisture absorption capacity, followed by SD-MD and MVD-GA. The difference of hygroscopicity between SD and MVD was determined by both microstructure analyzed by inverted fluorescence microscope and hydrophilic sites reflected by the thermodn. properties and Fourier transform IR (FT-IR) spectra, while the hygroscopic difference of different MVD samples was mainly due to hydrophilic sites. Besides, the bright yellow color of MVD samples was superior to the dark brown color of SD samples and the former also produced more characteristic volatiles (2,4-decadienal and 2,4-nonadienal). In addition, silicon dioxide (SiO2) was found to be an effective anticaking agent. The results showed that a combination of MVD-MD-SiO2 could solve the hygroscopicity problem of traditional chicken powder.
22047-25-2, 2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.
2-Acetylpyrazine, also known as 1-pyrazinylethanone or fema 3126, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R’, where R = aryl group and R’=alkyl group. 2-Acetylpyrazine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 2-acetylpyrazine is primarily located in the cytoplasm. 2-Acetylpyrazine has a bitter, bread crust, and chip taste.
2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
2-Acetylpyrazine is a nitrogen containing compound that has been used in biological studies. 2-Acetylpyrazine has been shown to have inhibitory properties against the growth of prostate cancer cells and other cell lines. It also inhibits the production of fatty acids and epidermal growth factor, which are important for cellular proliferation. The inhibition is due to the photochemical properties of 2-acetylpyrazine, which cause the formation of reactive species that react with biological molecules. The reactive species may be generated by either a reaction mechanism or a reaction pathway that involve coordination geometry. 2-acetylpyrazine has also been used as a fluorescence probe for fatty acid detection in lipid bilayers and liposomes., Application In Synthesis of 22047-25-2
