Abstract:
Food is essential for a human being to survive. Therefore, for safe consumption, the
quality of the food is important. Due to the ever-increasing demand for food products,
adulteration is a very common process for gaining extra profit. Liquid foods, such as
milk, honey, wines, fruit juices, and other cheap liquids are easily mixed with adulterants.
Artificial liquid foods prepared accordingly hinder the natural quality of food, but seem
to be real products. Therefore, by following a wide range of laboratory methods, experts
can identify adulterants and even estimate the amount of adulterant and compound
composition. But all these detection methods are not easy to use, time-consuming and
expensive. In the modern era, research papers in this particular field have shown that
different types of spectroscopy and different techniques operated at a vast range of
wavelengths have been used to identify contaminants in liquid products. But, recent
studies have also focused on the development of low-cost portable devices to detect
food mixing in field conditions and to obtain qualitative results in product composition.
Accordingly, in this work, an AS7265x sensor with a spectrometric concept was used
to detect impurities in liquid products. This multi-spectral sensor can detect spectra
ranging from Visible to NIR and can detect any change in the spectrometric profile
against the original profile recorded in the system for qualitative analysis of the liquid
food samples such as juice, honey, and dairy products. So, the consumer can identify
the quality of the food product in advance.
