“…They used silver nanoparticles as SERS substrates and measured the Raman spectra of the samples in the range of 1200 cm -1 to 800 cm -1 . The characteristic peaks of Sudan II and Sudan IV at 1388 cm -1 and 1564 cm -1 , respectively (42). PLS regression was used to build calibration models for Sudan II and Sudan IV based on the reference and spectral data (42).…”

“…The characteristic peaks of Sudan II and Sudan IV at 1388 cm -1 and 1564 cm -1 , respectively (42). PLS regression was used to build calibration models for Sudan II and Sudan IV based on the reference and spectral data (42). Their results showed that the models had good accuracy and precision, with RMSEP of 0.023 mg/kg and 0.026 mg/kg for Sudan II and IV respectively.…”

“…The method achieved a classification accuracy of 100% for both pure and adulterated sesame oil samples. Another study by Adade et al [26] used surface-enhanced Raman spectroscopy (SERS) combined with chemometrics to detect the presence of Sudan dyes as adulterants in crude palm oil. Chemometric methods such as PCA, LDA, QDA, SVM and ANN were used to classify the samples.…”

In this study, an innovative odor imaging system capable of detecting adulteration in quince seed edible oils mixed with sunflower oil and sesame oil based on their volatile organic compound (VOC) profiles was developed. The system comprises a colorimetric sensor array (CSA), a data acquisition unit, and a machine learning algorithm for identifying adulterants. The CSA was created using a method that involves applying a mixture of six different pH indicators (methyl violet, chlorophenol red, Nile blue, methyl orange, alizarin, cresol red) onto a Thin Layer Chromatography (TLC) silica gel plate. Subsequently, difference maps were generated by subtracting the “initial” image from the “final” image, with the resulting color changes being converted into digital data, which were then further analyzed using Principal Component Analysis (PCA). Following this, a Support Vector Machine was employed to scrutinize quince seed oil that had been adulterated with varying proportions of sunflower oil and sesame oil. The classifier was progressively supplied with an increasing number of principal components (PCs), starting from one and incrementally increasing up to five. Each time, the classifier was optimized to determine the hyperparameters utilizing a random search algorithm. With one to five PCs, the classification error accounted for a range of 37.18% to 1.29%. According to the results, this novel system is simple, cost-effective, and has potential applications in food quality control and consumer protection.

This paper tracks the maladministration of CPO exports by conducting a judicial review of CPO export policies by the Ministry of Trade of the Republic of Indonesia. This study uses a normative legal analysis with a field research approach. The results of the judicial review of this study are that the policy of temporarily stopping the export of Crude Palm Oil by the government is entirely appropriate, considering that previously there was maladministration carried out by individuals at the Ministry of Trade involving palm oil entrepreneurs in three companies, the occurrence of export permits has entered the criteria for maladministration because the three companies The CPO manager does not have an export permit which causes state economic losses due to rising cooking oil prices due to excess CPO being exported.
