What is the usage ratio of sodium alginate as a thickener?

Sodium alginate, as a thickener, has different usage ratios depending on the type of food. The following are some general usage ratios in common foods:

Beverages: The typical amount added is 0.05% - 0.2%. For example, in fruit juice drinks and plant protein drinks, adding about 0.1% sodium alginate effectively prevents the precipitation of fruit pulp and protein, resulting in a uniform texture and smooth taste.

Dairy products: The usage amount is generally between 0.1% and 0.5%. Taking yogurt as an example, adding 0.2% - 0.3% sodium alginate can improve the texture of the yogurt, prevent whey separation, make the yogurt thicker, and give it a richer taste.

Ice cream: The addition ratio is typically 0.15% - 0.3%. At this ratio, sodium alginate can control the growth of ice crystals during freezing, resulting in a fine texture and improved melt resistance, extending the holding time at room temperature.

Jams and jellies: The amount of sodium alginate used is typically 0.5% - 1.5%. In jams, adding about 1% sodium alginate gives the jam a suitable consistency, making it easy to spread, while preventing syneresis during storage; in jellies, this ratio allows the formation of a gel structure with elasticity and toughness.

Meat products: The general usage amount is 0.2% - 0.5%. Adding 0.3% - 0.4% sodium alginate to sausages and luncheon meat can improve the water retention and binding properties of the meat filling, resulting in a tight structure, reducing water and nutrient loss during steaming, and improving yield.

Noodle products: In bread and pastries, the amount of sodium alginate added is typically 0.1% - 0.3%. For example, in bread making, adding about 0.2% sodium alginate can improve the rheological properties of the dough, enhance the toughness and extensibility of the dough, increase the bread volume, make the internal structure fine and uniform, slow down the staling rate of the bread, and extend the shelf life.
