Abstract

Many food safety incidents have occurred in the world in the past 20 years, causing major threats and harm to human life and health. Each country or region has established different food safety management systems (FSMSs) in response, to increase food safety and to reduce food safety risks. Hence, it is important to develop an FSMS service platform with convenience, consistency, effectiveness, scalability, and lightweight computing. The aim of this study is to design and propose an IOTA Tangle-based intelligent food safety service platform for bubble tea—called IF4BT—which modularizes and integrates hazard analysis and critical control point (HACCP) principles to increase data transparency. The deep learning inference engine is based on long short-term memory and Siamese networks to check and extract significant rare data of high-risk factors, exception factors, and noises, depending on daily check and audit. IF4BT can ensure the correctness of the information of food manufacturers, so as to increase food safety and to reduce food safety issues such as allergen cross-contamination, food expiration, food defense, and food fraud.

Highlights

In the past 20 years, many major food safety incidents have occurred in the world, e.g., the melamine incident, plasticizer incident, toxic starch incident, toxic soy sauce incident, gutter oil incident, etc. [1,2,3]
Food safety: To list all hazards in the processes, including acceptance testing of raw materials, processing, manufacturing, packaging, storage, and transportation. This ensures food hygiene and food safety, which can reduce the pathogenic bacteria and prevent food poisoning; Allergens: In addition to the outer packaging being clearly marked, allergens must be controlled, and sources of allergens must be prevented from cross-contaminating the product; Food defense: Prevent food from being physically, chemically, biologically, or radioactively contaminated in a deliberate manner; Food fraud: Manufacturers are prohibited from making fakes, counterfeiting, diluting, false labeling, using raw materials from unknown sources, or making false or misleading claims about products
Is shown in Figures 1 and 2: (1) the ingredients are tapioca balls, milk, tea, and sugar; (2) the service platform is based on IOTA Tangle; (3) the food safety management system is based on hazard analysis and critical control point (HACCP) principles; and (4) reports are in the form of audit forms, warning messages, analysis reports, and XML reports

Summary

Introduction

In the past 20 years, many major food safety incidents have occurred in the world, e.g., the melamine incident, plasticizer incident, toxic starch incident, toxic soy sauce incident, gutter oil incident, etc. [1,2,3]. In the past 20 years, many major food safety incidents have occurred in the world, e.g., the melamine incident, plasticizer incident, toxic starch incident, toxic soy sauce incident, gutter oil incident, etc. Food safety incidents can present major threats to human life and health. Governments and industries of various countries are actively investing in the field of food safety [4,5]. Each country or region has formulated different food safety management systems (FSMSs) to increase food safety and reduce food safety risks [6]. Each national accreditation body (AB) and certification body (CB) issues a certification after certifying that the production line or the product meets food safety standards. Manufacturers need to sell goods internationally, so they must have different food safety certifications. The CB needs to audit production status of the manufacturer from time to time. There is a lack of professional confirmation of each process
