Research ArticleOpen accessPhrase in the titleHead-Space Solid Phase Micro-extraction Followed by GC/MS Analysis of the Volatile Components in Seeds of Cinnamonum camphoraYang Yong, Tao WenyiThe volatile components in seeds of Cinnamomum camphora were analyzed by Solid Phase Micro-extraction (SPME) combined with GC/MS. Twenty four main kinds of volatile compounds, among which the Sesquiterpene (29%), 3-Hexen-2-one (25%) and Monoterpene (10.22%), were separated and analyzed. …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,382 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCharacterization of Flavor Properties of Sufu by HS-SPME/GC-MS, Electronic Nose and Electronic Tongue Combined with Multivariate Statistical AnalysisXiaoli Xi, Yanli Ma, Jingxuan Ke et al.Flavor is the main quality characteristic of sufu. The flavor of different types of sufu varies greatly, which will affect the preference and selectivity of consumer for sufu. To explore the flavor characteristics and distinguishing methods in different types of sufu, the volatile flavor components and free amino acids of 5 kinds of commercial sufu were determined by HS-SPME/GC-MS and … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 12 Jan 2022 · 6,394 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCharacterization of Biochemical Compositions, Volatile Compounds and Sensory Profiles of Cabernet Sauvignon Wine in Successive Vintages (2008-2017)Yufeng Ding, Yanli Ma, Suping Li et al.Cabernet Sauvignon grape is an emblematic cultivar of Huailai region, China, allowing obtaining wines accounts for a large proportion of national consumption. This work aimed to determine the differences in basic parameters, organic acids, phenolics, volatile compounds and sensory profiles of Cabernet Sauvignon wines of successive vintages (2008-2017). The total organic acids content ranged from 7.03 to 42.33 g L-1, … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 17 Aug 2020 · 6,972 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of Ultra-High-Pressure Treatment on the Chemical Composition and Aroma of Flue-Cured Tobacco Leaves for Heated Tobacco ProductsXinbo Lu, Jie Yin, Ying Yuan et al.The influences of different Ultra-High-Pressure (UHP) treatments on the chemical composition and the low-temperature pyrolysis products of Flue Cured Tobacco Leaves (FCTL) that applied in heated tobacco products were investigated in this study. Results indicated that UHP treatment reduced total alkaloids content significantly (p<0.05), especially 500-600 MPa treatment group (2.34±0.00%, 2.34±0.01%). Increase in sugars and potassium content were observed after … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 19 Oct 2025 · 2,150 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImplementing a Hybrid VMD–BiTCN–BiGRU Architecture With Intelligent Optimization for Agricultural Commodity Price Prognostication in Gujarat MarketsJignesh Hirapara, Ratnesh Kumar Namdeo, Ankit Kumar Dubey et al.In the agricultural sector, the prices of pulses require adequate forecasting to plan farming activities, store and market, and guide policy-making. However, the pulse price series is highly volatile, seasonal, nonstationary, and nonlinear, and thus conventional linear time series models are not necessarily very effective. In the suggested framework, the raw price data series is decomposed using Variational Mode Decomposition … …Journal of Computer Science, Vol. 22, Issue 7 · 1 Aug 2026 · 1,021 accessesView PDF Cite
