What is rancidity? Where will you generally find it?
Answers
Explanation:
Rancidity can occur in many products or ingredients during storage. It affects taste and odor, and can have an impact on nutritive value. Two major rancidification pathways are recognized in extruded products. Enzymatic rancidity is catalyzed by the presence of certain enzymes (examples are peroxidases and lipases). The heat treatment experienced during extrusion is usually sufficient to destroy these enzymes. However, if ingredients containing these enzymes are stored in their raw or untreated state, they will become rancid before extrusion and will contain rancidity by-products that will impact flavor and odor. For many ingredients (especially whole seeds), it is important to heat treat the ingredient as quickly as possible after the seed coat is broken as this action triggers the enzymes responsible for rancidity. Extrusion is very effective in controlling enzymatic rancidity if the raw materials are processed immediately after milling.
The second pathway responsible for rancidity is oxidation. Oxidative rancidity is a chemical reaction catalyzed by heat, ultraviolet light, heavy metals and oxygen. Many of these factors are obviously present during the extrusion process. Oxidative rancidity is best controlled by the addition of antioxidants and ‘oxygen scavengers’. Most antioxidants are added before extrusion even though there may be minor destruction during the process depending on the time and temperatures employed. There is a growing trend to utilize natural antioxidants such as mixed tocopherols, rosemary, and other unique ingredients. Often an ‘antioxidant package’ containing antioxidants and oxygen scavengers are used in synergy. Oxygen scavengers such as ascorbic and citric acid appear to increase the effectiveness of antioxidants.
