Electrical impedance measurements for detecting artificial chemical additives in liquid food products

Electrical Impedance Spectroscopy for Quality Assessment of Meat and Fish: A Review on Basic Principles, Measurement Methods, and Recent Advances

“…According to the biological objects, application of EIS can be divided into three aspects, that is, electrical impedance tomography in medical imaging [2][3][4], quality and safety assessment in food industry, and phytophysiology in agronomy [5][6][7]. Research objects and targets of EIS applied in food are abundant and extensive, including for fruits, such as study on dry matter content of durian [8] and ripening of banana [9], for vegetables, such as changes in potato and spinach tissues during or after heating [10,11] and moisture content of carrot slices during drying [12], for meat, such as quality evaluation of pork meat during storage [13] and investigation of beef meat behavior during ageing [14], for chicken, such as discrimination of fresh and frozen-thawed chicken breast muscles [15], for fish, such as salt and moisture content determination of salted rainbow trout [16] and freshness estimation of carp [17], for dairy products, such as real-time detection of bovine milk adulteration [18], and moreover for determination of the additives content in natural juices [19], fermentation process of bread dough [20], and quality assessment of cooking oil [21]. Nowadays customers pay more attentions on quality attributes of meat products, such as appearance, flavor, and nutrients.…”

Deteksi Pemalsuan Kopi Luwak Menggunakan Sifat Biolistrik Dan Jaringan Saraf Tiruan

“…Hal ini membuat pengukuran sifat biolistrik bahan mengunakan metode dielektrik berpotensi sebagai sensor deteksi kopi luwak. Metode dielektrik sudah dikembangkan untuk prediksi kualitas bahan makanan dan pertanian seperti kualitas daging babi (Giraldez et al, 2010); buah kering (Alfaifi et al, 2013); air kelapa (Franco et al, 2015); penurunan kualitas minyak goreng (Yang et al, 2016); bubuk sayur kering (Ozturk et al, 2016); penambahan bahan kimia aditif dalam produk makanan cair (Nakonieczna et al, 2016).…”

Experience of business community on how to detect and stop market distribution of juices not conforming to legal requirements

“…Self-control performed by participating manufacturers is a basic principle of all European quality control systems. It usually implements the most up-to-date techniques for laboratory research [16][17][18][19]. Manufacturers that participate in quality control systems operations widely apply voluntary audit on their enterprises.…”
