gelatinisation
The process of gelatinisation occurs when starch granules are heated in a liquid, causing them to swell and burst, which results in the liquid thickening.
2.2

2.4
enrichment
The practice of adding micronutrients back to a food product that were lost during processing.
2.5
mechanical raising agent
Adding air to a mixture by: whisking, creaming sugar and fat sieving
