Alkaline modified starch, also referred to as treated starch, is a type of modified starch created by treating regular starch with an alkaline solution, typically sodium hydroxide (lye) or potassium hydroxide. Here's a breakdown of its key aspects:

Process:

  • Standard food-grade starches (like corn or potato starch) are subjected to a controlled alkaline treatment.
  • The alkali causes minor fragmentation of the starch molecules, altering its properties.
  • The process is carefully monitored to achieve the desired modifications without degrading the starch excessively.

Properties and Uses:

  • Alkaline modification affects the way starch behaves in water. It can:
    • Increase solubility, making it easier to disperse in liquids.
    • Reduce thickening power (viscosity) compared to unmodified starch.
    • Improve freeze-thaw stability, preventing breakdown after freezing and thawing cycles.
  • These properties make alkaline modified starch useful in various food applications:
    • Thickeners in soups, sauces, gravies, and puddings (often alongside other starches for desired texture).
    • Stabilizers in bakery products and frozen foods.
    • Texturizers in candies, gummies, and low-fat products.

Safety:

  • Regulatory agencies like the US FDA and European Food Safety Authority consider alkaline modified starch safe for consumption when used within recommended levels.
  • It's generally classified as a Generally Recognized As Safe (GRAS) food additive.
