Food processing

Food processing builds on food science, encompassing all considerations for processing raw foodstuffs into forms suitable for human and livestock consumption. Several processing methods have shared considerations with pharmaceutical processing. Food processing also considers formulation, shelf-life, and stability. Processors must screen for toxins and detrimental changes that can occur during storage. Environmental impact, of both the raw materials and the recycling and disposal of waste food products and processing chemicals, must also be considered. Here are some of our application notes and articles relevant to food processing. Take a look to discover more!
