Abstract

This chapter provides an overview of the definitions, techniques (current and future) and implications for health of food processing. Food processing has profoundly impacted human biology and history by enhancing edibility, digestibility, and food safety. It diversifies dietary options, improves flavours, and extends shelf life, contributing to food and nutrition security. The economic value and trade of agricultural products are maximized through food processing, supporting livelihoods and employment along food supply chains. The Industrial Revolution led to large-scale, centralized food-processing operations, driving the globalization of the food supply chain and the development of food regulation systems. Food processing plays a crucial role in achieving the Sustainable Development Goals by ensuring the availability of healthy, affordable, and environmentally sustainable food products. Despite its environmental impact, food processing offers opportunities for reducing greenhouse gas emissions through novel processing and preservation technologies. Understanding food processing methods is essential for assessing their implications for nutritional content, human health, and planetary health. The diverse health impacts of processed foods and the debate over ‘ultra-processed food’ highlight the need for careful monitoring and innovation in food processing technologies.
