D
diatomaceous earth
Explanation: 

Detailed explanation-1: -Alginates are the salts of alginic acid. They are extracted from brown algae . Soluble alginates are widely used in the food industry as thickeners, stabilizers, and emulsifiers. Alginates are soluble in water-miscible solvents such as alcohols and ketones.

Detailed explanation-2: -Sodium alginate and most other alginates from monovalent metals are soluble in water and yield solutions of high viscosity, thus making them particularly useful as thickening agents.

Detailed explanation-3: -Alginic acid is an FDA-approved food ingredient in soup and soup mixes as an emulsifier, thickener, and stabilizer 5. It is also available in oral dietary supplements and is found in antacids such as Gaviscon to inhibit gastroesophageal reflux by creating a physical barrier in presence of gastric acid 9.

Detailed explanation-4: -Sodium Alginate is a pure type of dried, ground kelp (seaweed)-it’s commonly used to thicken food. It is the most economical thickener for Dyes of all types and it works as a thickener for other liquids as well. Use whenever you want to use dyes more like a paint.

Detailed explanation-5: -Sodium alginate (a food product derived from brown algae or seaweed) is a thickening and gelling agent that forms heat stable gels in the presence of calcium. This property allows cooks to make gelled spheres, in a technique known as spherification.
