Quantitative Detection of Acid Value During Edible Oil Storage by Raman Spectroscopy: Comparison of the Optimization Effects of BOSS and VCPA Algorithms on the Characteristic Raman Spectra of Edible Oils

Recent advances in the application of Raman spectroscopy for fish quality and safety analysis

“…Recently, analytical methods have been developed that based on SERS sensors for the determination of Hg 2+ in water (Qi et al, 2015; Sarfo et al, 2017), milk (Jiang et al, 2021), and wine (Wang et al, 2021). The most typical types found in biological samples are divalent forms of inorganic mercury (Hg 2+ ) and methyl mercury (MeHg) (Y. Xu et al., 2017; A. M. Yuan et al., 2019).…”

“…Due to the effectiveness of pesticides in protecting agricultural products and controlling pests, the application of pesticides has increased worldwide in recent years (A. Zhu, Xu, et al., 2021). However, due to the uncontrolled disposal and abuse of pesticides in the environment, the misuse of pesticides promotes their transit through the food chain leading to consumption by humans unconsciously (Jiang et al., 2021; Xu et al., 2020). Fish is a non‐negligible source of pollution for humans.…”

“…As alternatives to traditional methods, spectroscopic analytical methods, including infrared spectroscopy (IRS) (Kamruzzaman et al., 2015; D. Liu et al., 2013; L. Wu et al., 2019), Raman spectroscopy (RS) (A. M. Herrero, 2008a), nuclear magnetic resonance spectroscopy (NMRS) (X. Cheng et al., 2013), fluorescence spectroscopy (FS) (Hassoun et al., 2019), and hyperspectral imaging (HSI) (Cheng & Sun, 2014; Mathiassen et al., 2011) are extensively investigated in rapid and nondestructive measurements. They have advantages in providing spectral “fingerprints” of the samples depending on the molecular composition of the products and have been actively reported in various fields, such as materials science (Ding et al., 2016), biology (Auner et al., 2018), and food science (Beganovic et al., 2019; Jiang et al., 2021; H. Jiang et al., 2020). Fluorescence is due to UV or visible fluorescence emitted by substances that absorb UV or VIS, while this technique is highly sensitive to environmental conditions because fluorophores may react with other substances and then induce quenching (Hassoun et al., 2019).…”

“…With the recent powerful technical advances of nanomaterials and emerging versatile SERS substrates, SERS has provided a viable platform for rapid, nondestructive, and sensitive identification of hazardous contaminants in food. Recent reviews exhibit that RS and SERS have offered the promising possibility in foodstuffs safety inspection (Craig et al., 2013; Jiang et al., 2021; Petersen et al., 2021; Wang et al., 2021), antibiotic residues evaluation (Girmatsion et al., 2021), bacterial recognition (Ahmad et al., 2021), meat quality determination (Beganovic et al., 2019), water pollution measurement (Z. Li et al., 2015), microorganism detection (Wang et al., 2018), and nondestructive analysis of agri‐foods (Wang et al., 2021). These reviews are mainly concentrated on applying RS or SERS to food quality and safety extensively.…”

High Precisive Prediction of Aflatoxin B1 in Pressing Peanut Oil Using Raman Spectra Combined with Multivariate Data Analysis

“…Raman spectroscopy uses inelastic scattering to analyze the sample, the sample does not need pretreatment, and the instrument is simple and convenient to operate [ 12 ]. In recent years, Raman spectroscopy combined with chemometric methods has been widely used in the fields of variety identification, quality analysis, and adulteration detection of edible oils [ 13 , 14 , 15 , 16 , 17 , 18 ]. However, in the detection of mycotoxins in edible oils [ 19 ], the existing research has used the synthesis of highly specific substrate materials to enhance the absorption intensity of specific Raman characteristic peaks.…”
