“…Hence, there is a real need for sensors that can make it possible to monitor and field-check detection. Researchers have developed portable biosensors that can be implemented in water, tea, juice, and milk with simple operation techniques, which are more desirable [4], [6]- [9], [24]. To determine the presence or absence of an enzyme inhibitor (malathion) in milk transducer with the polymer film formed on it containing the immobilized enzyme is immersed in a prepared milk sample.…”

“…Toxicity of OPs is based on the inhibition of acetylcholinesterase (AChE) enzyme in the central nervous system, and as a result, the synaptic concentration of acetylcholine will be higher than usual [3]. The results of automated monitoring, which provides information on the levels of various pesticides and organophosphate compounds in food products, show an increase in the total amount of pesticides in dairy products [4][5][6][7] due to veterinary practice against insects by applying directly in dairy plants and agriculture.…”

Immense use of an insecticide such as malathion has initiated a hindrance to the environment and has increased possible risk to human health via milk and milk products. The presence of insecticide residues in milk products is an alarming signal to set up a string monitoring system. Since their risk to human health, the determination of organophosphate pesticide levels in dairy products is essential. This study shows biosensors' development for the detection of residues of the pesticides generally used in agriculture to increase productivity, which has high toxicity and selective action, a significant part of which falls into crop and livestock products. The test system described in this paper is based on the immobilization of acetylcholinesterase on glass rods by colorimetry as a detection technique. The application of the biosensor to the analysis of the real sample confirmed its reliability. The developed biosensor test system showed excellent analytical performance with limits to detecting the concentration range of residual amounts of the acetylcholinesterase enzyme inhibitor -malathion insecticide (up to 0.089 mg/kg), along with acceptable reproducibility and stability. Distinct advantages of enzyme-based biosensors are high sensitivity, convenience, quick response, cost-effectiveness, portability, and a possibility to use for environmental detection purposes. The biosensor can be used for the analysis of organophosphorus pesticides with anticholinesterase action. It can be concluded that the benefits of using immobilized enzymes are significant since it will bring advantages for the food, pharmaceutical, and medical device industries.

“…One example of an organophosphate insecticide is malathion, which kills insects such as fleas and ants that attack plants. Malathion has been detected so far using chromatography [ 4 – 5 ], colorimetry [ 6 ], and mass spectrometry [ 7 ], although these methods are complicated and time-consuming and require expensive equipment with specialized expertise. It is therefore necessary to develop a technology that can detect pesticides quickly, easily, and economically.…”

Graphene quantum dots (GQDs) were made via a hydrothermal process with glucose as a precursor undergoing carbonization. Different spectroscopic techniques were used to analyze the optical characteristics of GQDs, including UV–visible, photoluminescence, FTIR, and Raman spectroscopy. Atomic force microscopy, transmission electron microscopy, and X-ray diffraction were used to characterize the morphological and structural properties of GQDs. An electrochemical sensor was developed by drop casting GQDs on a glassy carbon electrode (GCE). The sensor detects the organophosphate pesticide malathion in a selective and sensitive manner. Using cyclic voltammetry, the sensor’s oxidation–reduction behavior was investigated. Electrochemical impedance spectroscopy was conducted to study the electrochemical properties of the modified the GQDs/GCE working electrode, which showed excellent charge transfer properties. We measured malathion in varying concentrations between 1 to 30 µM using differential pulse voltammetry, which resulted in a limit of detection of 0.62 nM. GQDs can thus be used to develop electrochemical sensors for the detection of pesticides in water.

“…Ince (2014, 2018) have determined aflatoxin M1 levels in buffalo milk and kaymak samples from the same province. Kara and Ince (2016) have also researched malathion and malaoxon contaminations in buffalo milk samples from Afyonkarahisar province. Çınar et al (2019) have studied the compositions of general and fatty acids in buffalo milk samples from six different provinces.…”

The aim of this study was to analyze the chemical composition in terms of dry matter, protein, fat and ash contents, mineral content by laser ablation inductively coupled plasma mass spectrometry and atomic absorption spectroscopy methods and aroma profile by solid phase microextraction (SPME) method of buffalo kaymak (clotted cream) samples collected from the Çukurova region in Turkey. The results of our analyses showed that the kaymak samples contained an average of 85.31% dry matter, 78.00% fat, 4.01% protein, and 0.44% ash. Forty volatile compounds were identified comprising four aldehydes, three ketones, eight acids, five alcohols, six esters, six amines, and eight miscellaneous compounds. The average compositions of Ca, K, Na, Mg, Cu, Fe, Mn, and Zn were 408.96 mg L-1, 542.42 mg L-1, 238.84 mg L-1, 289.39 mg L-1, 0.12 ppm, 5.65 ppm, 0.08 ppm, and 14.70 ppm, respectively. When comparing these results with those in the literature using of kaymak samples from different locations, the samples from the Çukurova region had higher dry matter, fat, Ca, K, Na, Mg, and Fe contents and lower Mn content.
