dilution (2)

12176971656?profile=RESIZE_400xThis paper (purchase required) reports the use of a portable optical sensor (Multi-Spectral Imaging) to build a classification model for detecting milk adulteration. This encompassed mixtures of milk from different species (cow, goat, and sheep), as well as dilution of cow’s milk with water. The study's scope also included milk with diverse heat treatments, fat content, and commercial brands.

The authors report that discriminant analyses provided reliable predictive models, with Accuracy and Cohen's Kappa values ranging between 0.80 and 1. In quantitative studies, the quantification of milk mixtures at a minimum percentage interval of 10% was detected with Mean Absolute Error (MAE) values between 0.14 and 0.05, and 0.03 for cow's milk adulterated with water at adulteration levels of 5%.

The authors conclude that the portability of these instruments adds a significant advantage by enabling on-site and real-time determination and quantification of milk adulteration.

10390258488?profile=RESIZE_710xAn investigation, conducted by the carabinieri of the Nas of Ancona and coordinated by the magistrates of Ascoli started from a report of non-compliance of the milk carried out by the expert who has been working in the field of the milk industry for years as a quality "controller". The tanker involved had a double bottom that was invisible to the human eye and could be operated by the haulier who presses that button at the most appropriate time to bypass any checks and carry out his plan: mix milk with water. 

For the leaders of Trevalli the fact was considered as "isolated" and immediately denounced. But according to the expert, it should be seen as a "system" as it is "unthinkable" that a similar investment, with the transformation of the vehicle into a complex system of retractable hatches, is made by the individual haulier without periodic gain.
