... Olive oil is highly appreciated worldwide due to its unique and distinct flavor, recognized nutritional properties, and beneficial health effects. Due to its price and increasing demand by consumers, extra virgin olive oil (EVOO) is one of the most prone to mislabeling [1]. Several fraud practices have been detected in the olive oil market, including the mislabeling of the oil category level or origin (cultivar, region, and production mode), and the deliberated incorporation of other edible oils. ...

... The band at 1642 cm −1 was attributed to the scissoring vibration of bound water [28]. The absorption peaks around 1366 cm −1 were due to the C-H deformation vibration [29]. The peaks around 1200-1000 cm −1 were attributed to C-O-H side groups and C-O-C glycosidic bond vibrations, suggesting the presence of pyran rings [30]. ...

... As reported by Yang et al. [15], fermentation by LAB usually leads to a decrease in pH value of juice. After 48 h of fermentation, the total acid content of apple juice showed an overall upward trend ( Figure 2B), and there was no significant difference between pasteurized and HHP treated cloudy apple juice [25]. LAB uses malic acid for growth and metabolism, converting it to pyruvic acid and then to lactic acid, which enriches the flavor and taste of apple juice. ...

... Medical studies have shown that consumption of silkworm pupae protein may be associated with a reduced risk of many diseases, such as cardiovascular diseases (hypertension and hyperlipidemia) [70][71][72][73][74][75], and cancer (hepatoma and gastric cancer) [76,77]. Additionally, enzymatically produced silkworm pupa hydrolysate is reported to possess several bioactive properties, such as inhibiting angiotensin-I converting enzyme (ACE) activity [70][71][72][73][74], antioxidant activity [78][79][80], immunomodulatory activity [81], improving hypercholesterolemia [75], and anti-tumor activity [76,77]. ...

... It is remarkably appreciated and included in many people's daily diet [1][2][3]. Fruits fermentation produces a bio liquid that contains several functional molecules [4,5] such as organic acids [5,6], polyphenols [7,8], melanoidins [9,10], and tetramethylpyrazine [11,12]. The production technique used has an impact on the quality of vinegar, while the vinegar-making process plays an important role in the removal and/or formation of new components. ...

... Before treatment, all samples were melted and homogenized at 35 °C. Zhu's methods were used to remove sugar from the CH [27]. Then, a 1 g CH sample was mixed with 2 mL 10% NaCl hydrochloric acid solution (pH = 2) and 2 mL acetonitrile. ...

... In the past 10 years, enzymatic hydrolysis has been frequently adopted as a means of producing bioactive peptides from the proteins of edible insects. In such studies, silkworm pupae were relatively popular for the purpose of bioactive peptide discovery [29][30][31][32][33]. Figure 1 shows a general workflow employed by many studies in the discovery of bioactive peptides. employed in such studies are summarized. ...

... The existing methods for the detection of PAEs in edible oil include gas chromatography (GC), gas chromatographymass spectrometry (GC-MS), high performance liquid chromatography (HPLC), and liquid chromatography-mass spectrometry (HPLC-MS) (Cheng and Chang 2016;Sajid et al. 2016;Zhou et al. 2016a;Huang et al. 2020). For PAEs with high boiling point and weak polarity, HPLC is a more suitable analytical method. ...

... sucrose) and trisaccharides (e.g. erlose) (Daniele & Casabianca, 2012;Wytrychowski et al., 2013;Zhu et al., 2019). With these nutritional and functional components, RJ exhibits a wide variety of pharmacological properties such as antiaging, anti-inflammatory, antitumor, and immunomodulating effects (Collazo et al., 2021;Guo et al., 2021;Uversky et al., 2021). ...

... with discernible isolation between fluoride and the water dip and their column efficiencies were in the range of 54,000-79,800 plates m −1 . Compared with recently reported polymeric AEC packings as summarized in Table 2 [7,13,[32][33][34][35][36][37][38][39], the efficiencies and peak symmetry on our column (79,800 N/m and 1.02 for Cl − ) was superior to that on the best polymeric packing known (68,000 N/m and As: 1.3) [35], and the analysis time (< 5 min) for above six inorganic anions excluding PO 4 3− was also shortest. Their basic separation performance was also provably better than those of some commercial latex-agglomerated columns such as Ionpac AS18 and Ionpac AS11-HC-4 μm ( Table 1) (https:// assets. ...
