    Fast and Slow Roasting of Alcohol- and Honey-infused Coffee Blends: A Comparative Study of PAH and N-PAH Emissions by Hsin-Chieh Kung, Chung-Hsien Hung, Kun-Hui Lin, Bo-Wun Huang, Nicholas Kiprotich Cheruiyot, Guo-Ping Chang-Chien

    Published 2023-12-01
    “…The PAH diagnostic ratios indicated that the source of PAHs in green coffee was pyrogenic in nature and more specifically, petroleum combustion. Finally, the emission factors for the fast and slow roasting of green coffee were 1.36 mg kg−1 of coffee (7.49 µg BaP-TEQ kg−1) and 0.483 mg kg−1 (1.35 µg BaP-TEQ kg−1), respectively. …”

    Exploring phytochemical, antioxidant, and antimicrobial properties of Plumeria pudica Jacq. leaves by Kavan Shukla, Kunal N. Odedra, B. A. Jadeja

    Published 2025-01-01
    “…The results of the phytochemical evaluation indicated that both IPA and hydroalcoholic extracts exhibited a superior phytochemical composition, emphasizing the higher extractive potential of IPA compared to the non-polar petroleum ether extract. The quantitative analysis revealed the predominance of IPA extract as the quantity of phenols (101 mg GAE/g dry-weight of plant extract), flavonoids (402.2 mg QE/g dry-weight of plant extract), carbohydrates (336 mg GLU/g dry-weight of plant extract), and proteins (164 mg BSAE/g dry-weight of plant extract) were highest in the IPA extract. …”
