Pasteurization of grain
As grain is a major ingredient in many food products, food safety becomes an issue for manufacturers to consider. Products in which they are processed do not always have the right conditions for enough Log reduction to render pathogens such as Salmonella inactive. It is therefore highly recommended to pasteurize grain before feeding it into your production line to avoid contamination, (spreading of Salmonella bacteria) and product recalls.
As food is primarily about flavor and nutrition, pasteurization should be incompliance with these factors. To retain the flavor and other organoleptic properties of grain it is essential for treatment to be carried out at reduced pressure. To prevent excessive moisture from spoiling the grain, the application of steam is applied under conditions at which condensation on the surface is limited, a high water activity is established and sufficient heat transfer is realized to render the harmful pathogens inactive.
Several outbreaks of Salmonella have been reported in recent years. For example in 2008-2009 people were hospitalized after contamination of flour. The significance of pasteurization has become clear after research from the Dutch PDV; 0,75 of all the loads of grain were tested positive for salmonella.
Log 5 is able to provide turnkey solutions to grain pasteurization. Helping you to keep the right balance between important qualities in grain products such as texture, flavor, nutrition and safety for consumption.
Challenges for pasteurization of grain
The pasteurization of dry materials as grains needs specific requirements. Due to the small size of the product and soft texture, hardening and discolorization occur easily. To prevent loss of product qualities of your products, new pasteurization techniques are required.
