IoT (Internet of Things) and Food Industry

            The relevant and popular IoT systems used for food industry include data acquisition system, data communication system, data analysis system and data usage [1].

            Data acquisition system

            Data acquisition system is usually comprised of the sensors that can sense the environment such as location, temperature, humidity, airborne dust, chemicals, gas, time, pH, impact, numeration, measurement, receiving still and motion pictures, etc.  These sensors shall collect real-time data of specified intervals resulting us to know the real time data which will be transmitted thru online system in order to save and analyze by transmitting thru data communication system.

            Data communication system

            The popular used data communication systems are the Internet/Ethernet systems, radio frequency identification (RFID) system and wireless sensor network (WSN) system that can be self-connected requiring low energy and little supervision of human being such as Bluetooth, Wi-Fi, ZigBee, Near Field Communication (NFC) [2].  The data will be sent online to data storage service system called a “Cloud Computing”, also known in short as “Cloud”, available for both free of charge and with charges, which can be accessible to data on Cloud from anywhere [3] including transmitting commands back to the source thru cloud system.

            Data analysis system and data usage

            For data analysis and data usage, real-time raw data is used for simple monitoring food products such as temperature fluctuations, impact, quantity, label printing errors, product grouping by bar codes, etc. by setting an alarm when data-level error occurs or saving data as a database for systematic traceability.

            Raw data will be used for analysis and planning for the purpose of improving the efficiency of the process and reducing the defects, such as planning the transportation of goods based on traffic information and routes, planting or production planning according to customer requirements, quality and safety predictions  based on internal (e.g. recipes) and external (e.g. temperature, time, humidity) factors, enabling to monitoring the qualities (e.g. color, texture, flavor, vitamins, etc.) and safety (e.g. food sterilization, microbial toxin production during storage, carcinogens in frying oil, etc.) in real time without destroying the samples for analysis and time saving for sample analysis, etc.

            For marketing and sales promotion, the data collected as a database can be used to forecast the customer needs or organize sales promotion programs to distribute more products, such as changing from First in – First out system to Least Shelf-life – First out system by using data to predict the remaining quality from time-temperature history instead of using the conventional expiration date.  According to the research, the product quality variability is reported to be reduced resulting to a greater reduction of expiry product [4].

            Applying IoT technology to support food standards will be very beneficial based on data acquisition in real time, secured and not lost, as well as, easily accessible and search; for instance, in case of data traceability to prove food fraud or counterfeiting products from other sources, including supporting food defense.

            In case the consumers wish to access the information on product allergens, they can easily access on their own through online channels.  Besides, the data can be used in critical point analysis, setting critical values and monitoring the critical point in real time.  Furthermore, self-management function is programmable by automation system or robot resulting to handle the problems more quickly and reduce bias or deviation by human decision-making, as well as, reduce the workloads of workers allowing the workers to spend time for other organizational developments more efficiently.

            In the future it is possible that IoT system will be applied to the entire food production chain from raw material production to waste management of food products by easily controlling the operations thru the application including access to consumer data as well.

            These technologies are increasingly playing significant roles in our lives.  The entrepreneurs, therefore, should adapt to respond to the rapid change of consumer requirements.

            We are pleased to provide the service to promote the food industry in Thailand and be a part of a sustainable food society.
