Agar Agar (Strip)
Food
Code: 253153
Food‑grade plant‑based gelling/thickening agent. Use 0.2–1.5%; dissolve at 90–95°C, sets on cooling.
Agar Agar (Strip) food‑grade hydrocolloid used as a plant‑based gelling and thickening agent in desserts, confectionery, and beverages.
| Benefit | Typical use level | Key food/tech findings | Sources |
|---|---|---|---|
| Gelling agent | 0.2–1.5% w/w | Thermo‑reversible gel; sets ~35–45°C after dissolving at ~90–95°C | Food Hydrocolloids |
| Texture & suspension | 0.1–0.5% w/w | Stabilizes particulates and provides clean, high‑clarity gel matrix | Codex |
*Use level refers to percentage in finished food. Adjust with sugar, acid, and salts to tune texture.
Mechanistic highlights
- Agarose network: Forms double‑helix junction zones on cooling that create a rigid gel matrix.
- Thermo‑reversibility: Melts on reheating above the melt point allowing rework.
- Electrolyte/acid sensitivity: High ionic strength and strong acids reduce gel strength.
Safety & practical use
- Usual use level: 0.2–1.5% in foods (up to 2% for very firm gels).
- Preparation: Disperse in water and heat to 90–95°C until clear; pour and allow to set during cooling.
- Upper tolerance: High intakes may cause GI discomfort as fiber; hydrate adequately.
- Allergens: Derived from red seaweed; does not contain common allergens.
- Strips or powder, off‑white to pale‑yellow
