“…The alcohol substances in the SS samples are summarized in Figure 1 B-b. The content of 2-hexanol has the highest content in the sample, but 3-heptanol and 3-furanmethanol have significant differences in the sample, and the content of these two substances is higher in the three kinds of J, A, and S. 1-Octen-3-ol content is generally low in Z. Interestingly, as can be seen from the Figure 1 B, there are also differences among different batches within the same region, which may contribute to their different storage methods—for example, different storage times and temperature [ 21 , 22 ]. As shown in Figure 1 B-c, the samples varied significantly according to the proportion of aldehyde substances in each.…”

Volatile organic compounds (VOCs) are the main chemical components of Schizonepetae Spica (SS), which have positive effects on the quality evaluation of SS. In this study, HS-SPME-GC-MS (headspace solid-phase microextraction-gas chromatography-mass spectrometry) and HS-GC-IMS (headspace-gas chromatography-ion mobility spectrometry) were performed to characterize the VOCs of SS from six different regions. A total of 82 VOCs were identified. In addition, this work compared the suitability of two instruments to distinguish SS from different habitats. The regional classification using orthogonal partial least squares discriminant analysis (OPLS-DA) shows that the HS-GC-IMS method can classify samples better than the HS-SPME-GC-MS. This study provided a reference method for identification of the SS from different origins.

“…Thermal processing (natural air drying and steaming drying) converts saponins of larger molecular weight into saponins of smaller molecular weight. Ginsenoside M-Rb 1 , M-Rb 2 , M-Rc, Re, Rg 1 , Rb 1 , Ginsenoside Rb 2 , Rc, Rd, Re, Rg 1 , and Ginsenoside Rd, Rk 1 , Rg 5 , Rg 3 are the major ginsenosides of white ginseng, red ginseng, and black ginseng, respectively [ 15 , 18 , 19 ]. Nonthermal processing (vacuum freeze-drying) can keep the shape and color of ginseng consistent with its fresh state, containing more natural active ingredients.…”

A method with ultrahigh performance liquid chromatography Quadrupole-Orbitrap tandem mass spectrometry (UHPLC-Q-Orbitrap-MS/MS) was applied for the quality evaluation of different processing and drying of American ginseng, including natural drying (ND), steam drying (SD), and vacuum freeze-drying (VFD). A total of 51 saponins were successfully identified in three processed products. Three processed American ginseng products were well-differentiated in orthogonal partial least-squares discriminant analysis (OPLS-DA). The S-plot also identified the marker compounds in each product, while the major ginsenosides of ND (malonyl (M)-Rd, M-Rb1, Rg1), SD (20 (S)-Rg3, 20 (S)-Rg2), and VFD (M-Rd, M-Rb1) were found. The results indicate that the method by vacuum freeze-drying can retain the content of rare ginsenosides and malonyl-ginsenosides. The marker compounds selected will benefit the holistic evaluation of related American ginseng products.

“…Figure 1 showed the multi‐gradient processing of preserved fruit and other traditional products. Some studies pointed out that gradient processing method could better protect the color and texture of fruits, vegetables, and meat products (Shi et al, 2021; Zhang et al, 2021). In addition, the preserved fruit gradient processing could increase the sugar content while removing moisture, which could improve the commercial value of dried fruit.…”

Apricot was treated by osmotic dehydration (OD) before air drying to protect its antioxidant activity and bioactive compound. The experiment set up three groups to pretreat apricot by OD in sucrose solution of different concentrations for 12 h in total, among which, OD‐1 was permeated in 60% solution for 12 h; OD‐2 was permeated in 45% and 60% solution for 6 h. OD‐3 was pretreated in 30%, 45%, and 60% solutions for 4 h. After pretreatment, apricots were dried at 60°C until the water loss rate reaching 75%. Results showed water loss rate and solids gained rate in the OD‐2 group were the highest and drying time was shortened effectively. Compared with control, all OD samples could maintain higher content of bioactive compounds and antioxidant capacity, and reduce browning. The OD‐2 pretreatment dried apricot could retain the edible quality, bioactive substances, and antioxidant capacity to the maximum extent. Novelty impact statement This research was improved according to the traditional processing technology of preserved fruit. In this study, it was found that under the same pretreatment time, the osmotic dehydration pretreatment with second‐order gradient concentration could effectively keep apricots' bioactive compounds and antioxidant activity during the drying process.
