Description
This dataset contains the raw data generated during the master’s research on the microencapsulation of liquid smoke by spray drying. The data are divided into three main parts: (1) characterization of the liquid smoke, encompassing volatile compounds analysis — with comprehensive GC-MS chromatographic fingerprints for global volatile profiling and targeted GC-FID chromatograms for estimating the area values of selected marker compounds — together with its physicochemical characterization; (2) microencapsulation process, with operating parameters and feed formulations, and mass balance of the process; and (3) characterization of the resulting microparticles, including moisture content, water activity, particle size distribution, morphology, and also GC-MS and GC-FID chromatograms. The dataset generally provides raw chromatograms (in PDF and instrument-native formats) and experimental spreadsheets, exported directly from the instruments/software without any post-processing. In cases where a file contains processed data, this is explicitly stated in its individual description. (2025-09-23)

PDF file containing preliminary chromatograms obtained during the extraction pretests of liquid smoke for volatile compound identification. The file includes GC–MS outputs from three extraction approaches: solvent extraction using ethyl acetate and dichloromethane, and headspace solid-phase microextraction (HS-SPME) using a Carboxen/PDMS microfiber. These analyses were conducted only to verify the detectability of compounds previously reported in the literature. No experimental records were kept for solvent ratios, dilutions, extraction time, temperature, injection parameters, or GC heating program. Instrument specifications and operational details are described in the corresponding master’s dissertation and related publication. The combined PDF includes the following GC–MS data files, in this order: “Data file: Amostra met 2.D” – corresponding to 01A_pretest_extraction_liquid_smoke_ethyl_acetate.pdf (extraction with ethyl acetate). “Data file: Amostra.D” – corresponding to 01A_pretest_extraction_liquid_smoke_dichloromethane.pdf (extraction with dichloromethane). “Data file: Fumaça líquida – fibra preta.D” – corresponding to 01A_pretest_extraction_liquid_smoke_hs-spme_carboxen-pdms.pdf (HS-SPME using Carboxen/PDMS microfiber). Note: The HS-SPME (black fiber) file does not include the chromatogram graph, containing only the compound identification attempt data exported from the GC–MS software.

PDF file containing the GC–MS volatile profiling of liquid smoke (Lot 1) obtained using headspace solid-phase microextraction (HS-SPME) for compound identification. This batch was the first sample received from the supplier and was analyzed to characterize its volatile profile prior to spray drying. After evaluating the available volume, it was determined that Lot 1 would not be sufficient for the microencapsulation stage; therefore, it was used exclusively for analytical characterization. The file includes the GC–MS Autotune record, followed by the chromatograms listed below in the order in which they appear in the document: • 01B_chromatogram_liquid_smoke_blank_pdms-dvb_fiber.pdf — GC–MS chromatogram of the blank from a 65 µm PDMS/DVB SPME fiber, used to identify and subtract background or contaminant signals. • 01B_chromatogram_liquid_smoke_lot1_rep1.pdf — GC–MS chromatogram of liquid smoke, Lot 1, replicate 1. • 01B_chromatogram_liquid_smoke_lot1_rep2.pdf — GC–MS chromatogram of liquid smoke, Lot 1, replicate 2. • 01B_chromatogram_liquid_smoke_lot1_rep3.pdf — GC–MS chromatogram of liquid smoke, Lot 1, replicate 3. • 01B_chromatogram_liquid_smoke_alkane_standard.pdf — GC–MS chromatogram of the alkane standard used for retention-index calibration. Instrument specifications, operating conditions, and compound identification procedures are described in detail in the corresponding master’s dissertation and related publication.

PDF file containing the GC–MS profiling of liquid smoke (Lot 2) obtained using headspace solid-phase microextraction (HS-SPME) for volatile compound identification. This analysis corresponds to the second batch of liquid smoke received and was performed to characterize its volatile profile prior to spray drying. The file includes the GC–MS Autotune record, followed by the chromatograms listed below in the same order in which they appear in the document: 01C_chromatogram_liquid_smoke_blank_new_pdms-dvb_fiber.pdf – GC–MS chromatogram of the blank using the new blue PDMS/DVB fiber, used to identify and subtract background or contaminant signals. 01C_chromatogram_liquid_smoke_lot2_rep1.pdf – GC–MS chromatogram of liquid smoke, Lot 2, replicate 1. 01C_chromatogram_liquid_smoke_lot2_rep2.pdf – GC–MS chromatogram of liquid smoke, Lot 2, replicate 2. 01C_chromatogram_liquid_smoke_lot2_rep3.pdf – GC–MS chromatogram of liquid smoke, Lot 2, replicate 3. 01C_chromatogram_liquid_smoke_alkane_standard.pdf – GC–MS chromatogram of the alkane standard used for retention index calibration. Instrument specifications, operating conditions, and compound identification procedures are detailed in the corresponding master’s dissertation and related publication.
