Stabilization is a thermal process used to inactivate the enzymes that naturally degrade dry ingredients after harvest, milling or dehulling. Left active, enzymes such as lipase and lipoxygenase break down fats, generate off-flavors and shorten shelf life. By heating the product under controlled moisture for a precise duration, stabilization stops this enzymatic activity at the source. Revtech\u2019s continuous stabilization technology combines electric heating and direct steam injection in a closed vibratory tower, for homogeneous enzyme inactivation without gas, without open flame and without a separate re-drying step.<\/p>\t\t\t\t<\/div>\n\t\t\t\t

Why stabilization matters for shelf life and quality<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Many grains, brans, seeds and pulses carry highly active enzymes in their outer layers and germ. As long as the kernel is intact, these enzymes stay separated from their substrates. Once the product is milled, cut or dehulled, they come into contact with fats and proteins and start degrading them.<\/p>

The consequences are well known to processors: hydrolytic rancidity caused by free fatty acid (FFA) formation, oxidative off-notes, bitterness, loss of baking or binding performance, and a shelf life that can drop to a few days for the most sensitive products. Enzyme inactivation is the only way to stop these reactions durably, and it must take place as early as possible in the process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

How enzyme inactivation works<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Enzymes are proteins. Heat, and especially moist heat, denatures them irreversibly. This thermal enzyme inactivation, also referred to as enzyme inhibition, enzymatic inhibition or enzymatic deactivation, is the reference method to stabilize dry ingredients. Steam is far more effective than dry hot air for this purpose: it transfers energy quickly to the product surface and brings the moisture needed for denaturation, which allows shorter residence times and lower thermal impact on the product.<\/p>

Each enzyme has its own heat resistance. Peroxidase is among the most heat-stable enzymes found in cereals and oilseeds, which is why its residual activity is widely used as the reference marker to confirm that less resistant enzymes, such as lipase, have been fully inactivated.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Revtech\u2019s stabilization equipment is a continuous vibratory system designed for precise and reproducible enzyme deactivation of dry ingredients. The product is fed into a vibratory tower, where it is first pre-heated by direct contact with an electrically heated coil. Saturated steam (around 1 bar \/ 100 \u00b0C) is then injected directly onto the product, in a closed and controlled atmosphere.<\/p>

Four key process parameters are continuously controlled and fully adjustable for every product:<\/p>
