The microbiological analysis of food has an important role in assessment of the quality and safety of foods. There is a direct relationship between bacterial numbers and product shelf life as growth of bacteria can result in organoleptic changes in the food, including off-colours and off-odours, rendering it unacceptable to…

In a food processing environment, microbiology is an essential focus to ensure the safety of the end food product. In this article Andrew Snelson explains the processes that ensure microbiological safety during cocoa bean processing. Cocoa butter and cocoa liquor are extracted from the seed of the Theobroma cocoa tree.…

Conveyor belts are the arteries of all food processing sites. They support products from a raw material stage to final packaging and endure all the processes in between. They must be able to work safely and effectively with all manner of different product characteristics, from viscous ingredients to raw meats.…

Many food producers underestimate the effects of packaging on quality deterioration. In order to preserve product quality, it is of paramount importance to thoroughly understand and focus on the interactions taking place between the packaging and the product. It is only by applying this knowledge to tailor packaging to individual…
