Blockchain Based Solutions for Milk Procurement Management and Adulteration Detection

Abstract

In our day-to-day life, milk is a fundamental component that is rudimentary for many food products. Consuming milk regularly is very important because it is a mixture of various macro and micronutrients and is a source of proteins, fats, carbohydrates, and vitamins. Particularly in our nation, women’s empowerment and milk production are closely related. Furthermore, rural Indian communities rely heavily on small holder dairy farms for their livelihoods, and women play an important role in milk production. The dairy sector is estimated to contribute around 6% of the country’s agricultural GDP, with the value of milk production in India exceeding 200 million ton by the year 2023 [1]. Milk is a highly perishable commodity, when not handled properly it is susceptible to microbial spoilage. The milk after production must be processed properly to retain its quality till consumption. Nowadays, many milk vendors are adulterating the milk for financial gain. Consumers have the rights to obtain good and safe milk, as it is largely consumed by people of all age groups. Supply chain process of a small holder dairy farming has been examined recently in Salem, Tamil Nadu, India and it has been observed that the current process in dairy involves the accumulated milk from dairy farmers are being poured into the milk cane, then being detected and sent to a larger container where it is mixed with all the other milk. In most cases, it would be impossible to separate fresh milk from un-fresh milk. Therefore, the objective of this research work aims to develop a Blockchain and IoT based solution for milk procurement and adulteration detection there by providing a complete milk traceability data to the consumers from production to consumption, and establishing a trust in providing quality milk to the society.
