Proposta metodológica para implementação de boas práticas de fabricação em um processo de caulim grau alimentar

Abstract

The Brazilian animal feed industry plays a crucial role in global food security, requiring mineral inputs, such as kaolin, to meet rigorous quality standards. Kaolin is widely used as a technological additive, acting as a mycotoxin adsorbent and binder in feeds. However, its industrial processing, if not controlled by adequate engineering parameters, presents critical risks of physical, chemical, and biological contamination, including the presence of heavy metals, dioxins, and pathogens. The main objective of this work was to propose an engineering project for the structuring and implementation of a robust Good Manufacturing Practices (GMP) system in a food-grade kaolin processing plant, in compliance with Normative Instruction No. 04/2007 and Decree No. 12.031/2024 of the Ministry of Agriculture, Livestock and Supply (MAPA). The methodology adopted consisted of the technical development of a set of Standard Operating Procedures (SOPs) and Self-Control Programs (SCPs), designed to mitigate risks at identified Critical Control Points (CCPs). The project covers everything from rigorous control of raw material and packaging reception, through engineering barriers against cross-contamination, such as the installation of magnetic separators and flushing procedures, to the sanitary defense of the plant through integrated pest control and sanitation. Additionally, a complete batch traceability system and a recall plan were structured to ensure process memory and responsiveness to non-conformities. The expected results from the implementation of this project include the assurance of final product safety, the systematic elimination of risk vectors, and full regulatory compliance of the manufacturing unit. It is concluded that the proposed GMP system is not merely a bureaucratic requirement, but an essential process engineering tool to ensure product quality and competitiveness in the national and international markets.
